Applications
The Energy Control System (ECS) allows for unambiguous cost center accounting.
Electrical as well as non-electrical energy and its consumption can be recorded,
optimized and billed to individual cost centers.
The U1601, U1602 and U1603 summators are at the heart of the Energy Control
System (ECS) and enable the recording and billing of both analog and digital quantities.
ECS operating software revision level: V2.57
The current operating instructions covering the latest firmware update are available for download
LON is a registered trade mark of the Echelon Corporation.

System Description
• Analog signals from orifice plates, measuring transducers or other measuring
instruments are acquired, analyzed and stored together with meter pulses from energy
meters, flow meters and heat meters at the intelligent U1601 summator.
• Each summator can be connected to up to 12 energy meters with pulse output. Data
collected at the meter inputs are integrated and stored according to various criteria to
a semiconductor memory with battery back-up.
• 64 channels are available for the generation of sums and/or differences based upon
meter values. Values from other summators which are connected to the ECS LAN can
be used to generate virtual channels as well. All of the stored measurement values
can be displayed at the summator.
• Stored values can be read out from the U1601 summator with a PC, or can be remote
queried with the help of a modem. A radio-controlled clock for correct time
synchronization or a printer for the generation of reports can be connected to the
second RS232 interface.
• Several summators can be linked to one another via the ECS LAN, a multi-master
compatible RS485 field bus, for applications which required the use of more than 12
inputs (analog/binary). The linking of up to 255 summators from 16xx series
instruments via the ECS LAN allows for the establishment of a powerful energy control
system, which is controlled and monitored with a PC.
• All of the instruments connected to the bus can be queried and programmed from any
desired summator thanks to the multi-master system structure. A limit value violation at
summator M can thus trigger a signal at summator N. Each bus user has access to all
data and functions throughout the entire system.
• LON is a new type of intelligent bus concept with allows controllers, sensors and
actuators to communicate with one another. In addition, up to 63 nodes can be
connected to a U1601 summator via the integrated LON network.
• Two freely programmable relays allow for the generation of messages or the triggering
of specific actions if certain criteria have been fulfilled.
• User generated programs can be installed to the summators through the use of the
system-specific programming language, Energy Control Language (ECL). The
summators can thus be adapted to customer-specific calculations, analyses,
monitoring and optimization independent of the energy control system.
• ECSwin PC software for configuring parameters at the summators, and for reading in
energy consumption data and displaying them in tabular and graphic form.

Channels
Cyclical Generation of Channel Registers
Due to the fact that many various energy data registers are made available to each
channel (33 registers without maximum values: Etot, EtotT1, EtotT2, Pmom, 10+1 times
Eday, 12+1 times Emon, 4+1 times Eyear), only the most important summations are
performed continuously, and less important summations are performed in accordance
with a rotating schedule. For example, Etot is calculated continuously, whereby Emon-
12 is determined less frequently (approximately every 30 to 90 seconds). Power values,
except for Pmom, are continuously calculated based upon energy values, and thus
need not be summated.

Channel Names
A name can be assigned to each channel with a length of up to 8 characters. These
names allow for improved channel identification during data processing, as well as for
graphic representations. System-wide access to a given channel is also enabled through
the use of such names.
<A> Etot Motor5
A system-wide search for a channel with the name “Motor5” is performed from
summator A, and total energy from this channel is graphically displayed (see also ECL
command: FINDER).
Channel Numbers
If inputs (E1 ... E12) are to be assigned to the channels, each input can only be assigned
to the channel which bears the same number, i.e.:
Inputs E / Outputs A
Channels

Virtual Channels
• Any unused channel can be utilized as a virtual channel for the generation of any
desired sums or differences which result from physical inputs or other virtual
channels. It makes no difference which summators within the ECS LAN the channels
have been assigned to!
• Unused physical channels can also be utilized as virtual channels, in which case even
the maximum value registers for the corresponding physical channel are made
available.
• The synchronizing-interval data logger can record data from virtual channels.
Differential Linking (ECL commands dVSUM and dVIRT)
As soon as they have been defined, incoming energy quantities (~ meter pulses) from
the source channels are continuously summed and the summed energy quantities are
fed to the virtual channel, “as if they had actually just been measured”. The virtual
channel is decoupled from the source channels and data can be manipulated as
desired.
Areas of application: logical coupling of input signals (as if the corresponding input
signals had been switched together to a single channel).
Example 1:
Channel 26 at summator D generates a cost center based upon channels 1 ... 5+8 from
summator B weighted with a factor of 0.7, and channel 4 from summator C weighted
with a factor of 0.3
H1=’B:dVSUM 1..5+8 0.7, C:dVSUM 4 0.3, D:dVIRT 26=’
Example 2:
Channel 10 is the difference between 1 ... 8 and total-sum channel 9
(sum of 1 ... 8 minus channel 9):

Channel Parameters (chapter 6.4, page 33)
Numbers Range
In order to ensure greatest possible accuracy, all internal calculation operations are
performed with 64 bit floating decimal point numbers. This means that 15 (!) significant
decimal places are possible.
Switching the Channel Display On and Off
The On/Off function only determines whether or not a channel is visible while browsing
through channel data at the display, or during read-out with '*' (ECL command:
ONOFF). The function of the channel remains otherwise entirely unaffected.
Channel Start/Stop
The Start/Stop function is used to determine whether or not meter pulses are to be
accepted at a given input (ECL command: STARTSTOP).
• A virtual channel which has been generated by means of “differential linking” can be
influenced with the Start/Stop function in an analog fashion.
• Since the binary input status of a channel is not influenced, this function can be used,
for example, to avoid taking undesired binary data into consideration.
Energy Metering
Meter pulses filtered out in this fashion are integrated, per channel, into a temporary
meter. The meter values are converted into their corresponding energy values every 1 to
2 seconds, and are added to total energy registers. Pulses are converted to energy
values by means of the following formula:

Power Calculation
Instantaneous power, PMOM, is determined based upon the interval between the
incoming pulses. All other power values are calculated from the corresponding energy
value, taking the corresponding time interval into consideration.
The calculation of power assumes the assignment of an energy unit of measure per hour
(kWh). The power factor must be adapted accordingly for other units of measure (e.g.
liters per minute) (ECL command: PFACTOR). The default value is 3600, and it would be
60 for the “liters per minute” example.
Formula for the calculation of power based upon energy E and duration dt:
P = E * Pfactor / dt
Only sensors which have been connected via the LON network are capable of
transmitting already calculated power and energy values to the summators.

3.3
Inputs E1 ... E12 and E1 ... E6 respectively (analog / binary)
Analog Inputs
For summator U1601 12 optically isolated analog inputs are available, E1 ... E12, for
summator U1603 6 optically isolated analog inputs are available, E1 ... E6. These can
switch settings and appropriate software settings.
One metering channel, 1 ... 12, can be assigned to each of the inputs, E1 ... E12,
one metering channel, 1 ... 6, can be assigned to each of the inputs, E1 ... E6.
The applied analog input value may correspond to a measured power quantity.
The input ranges (20 mA, 5 mA, 10 V, S0) must be pre-selected with the DIP switches,
as well as the I/O RANGE parameter. Energy is matched to the various ranges, and
calculated and recorded as a channel quantity with the configurable ANAFAKTOR and
ANAOFFSET parameters.
Binary Meter Inputs
The 12 analog inputs, E1 ... E12, of
A
D
summator U1601, and the 6 analog inputs,
E1 ... E6, of summator U1603 respectively,
can also be used as binary inputs (in
accordance with the S0 standard).
E
N
Configuration is accomplished by means of
A binary input recognizes two different levels, high level “1” and low level “0” (max. low
level adjustable with ECL command: LEVEL). Thus switching back and forth between
tariffs T1 and T2 can be performed with input 12. The synchronization pulse from the
electric utility can also be connected, for example, to input 11. Status can be queried via
software with the ECL command INPUT.
Debouncing Time and Trigger Edge
Debouncing time and the trigger edge can be configured individually for each of the
maximal 12 channels. Sampling time for all maximal 12 channels amounts to 5 ms.
• Debouncing time is adjustable from 10 ms to 2.55 s in 10 ms steps, ECL command:
PULSE
• High level trigger flank (1): Triggering occurs for change from low level to high level,
ECL command: EDGE
• Low level trigger edge (0): Triggering occurs for change from high level to low level.
If an input is used as a binary input, the selected debouncing time applies to this
operating mode as well. For example, if debouncing time has been set to 1 s, only those
signals are processed which remain stable at either high or low level for at least 1
second. Only debounced signals appear at the input status display at the control panel
as well.
3.4
Analog Outputs A1 and A2
Two configurable analog outputs can be driven with the ECL command ANA. The
output quantity (20 mA or 10 V range) must be selected with the DIP switches and the I/
Input channels can be recorded, scaled and read out continuously as transduced
quantities with the help of a background program (see also ECL command: ANA 13,
ANA14).

Gossen Metrawatt GmbH
3.5
S0 Outputs S1 through S4
Just like the relay outputs, four freely programmable S0 outputs allow for the forwarding
of messages when certain conditions have been fulfilled. Selectable voltage is limited to
50 V. Additionally, these outputs can be used as floating pulse outputs for the
transmission of meter readings to remote locations with the help of ECL background
programs (see ECL command: S0REL 1 ... 4).
3.6
Relay Outputs
Two freely programmable relays (changeover contacts) allow for the generation of a
message or the triggering of an action, if certain criteria have been fulfilled. For example,
a relay output can be activated if the mean power value within the synchronization
interval exceeds a certain value. The current relay status is displayed at the LCD under
summator status. A ?indicates that the contact is closed and active. Please observe the
characteristic values in the appendix.
Relay Names
A channel name can be assigned to each of the relays and may have a length of up to 8
characters. This name allows for improved relay identification during data processing, as
well as for graphic representations. System-wide access to a given relay is also enabled
through the use of such names:
<A> REL Horn=1
A system wide search for a relay with the name “Horn” is performed from summator A,
and this relay is activated (see also ECL command: FINDER).
3.7
Self Test
As long as the electronics are functional and no system error has been detected, the
status LED and the status relay are on. If the instrument electronics malfunction, the
relay is released and the LED goes out. A horn which can be driven with the status
relay’s break contact can be used to indicate a malfunction.
The current relay status is displayed in the status window (see chapter 5.8, page 26).
Functional testing can be expanded by means of appropriate programming (ECL
command: STATCHECK, see detailed information in online help: ? STATCHECK). For
example, the output can be deactivated (error condition) as soon as the 24 V power
supply drops to below 16 V, or if the condition of the lithium battery no longer allows for
reliable data storage.
3.8
RS232 Interface
Communications with a host computer (PC), a terminal, a modem or a printer is made
possible via the RS232 serial interface.
Access to All Measurement Data
A PC which has been connected to the RS232 interface has full access to all stored
system measurement values. ECSwin parameters configuring software, which runs on
the PC, manages all ECS data and allows for tabular data analysis.
Port Configuration
The RS232 port is configured in the DTE format (data terminal equipment), and signals
are conducted by a 9-pin D-SUB plug. The DTE configuration is compatible with
standard PC and terminal configurations. Wiring of the connector cable is described in
Gossen Metrawatt GmbH

3.9
ECS LAN
Several summators can be linked to one another via a multi-master compatible RS485
field bus (ECS LAN) for applications which require the use of more than 64 channels.
The connection can be established by means of a 2-wire cable using either bus or a line
topology. The maximum length per segment is1200 meters. Distances of several
kilometers between 2 summators can be accommodated with fiber optic transmission
and
4-wire technology.
A maximum of 255 summators can be connected to the ECS LAN. This means that a
maximum distance of approximately 300 km can be covered without additional
boosters.
Multi-Master System Architecture
The most significant advantage of the multi-master system architecture is the fact that
each of the bus users has full access to all of the data and functions encompassed by
the overall system. It is thus unnecessary to assign the designation of bus master a
single summator.
General Notes Concerning the ECS LAN
• The connector technology for the individual LAN segments can be freely selected and
combined.
• The longest cable length is determined by the transmission speed in accordance with
RS485. The ECS LAN normally runs at 62.5 KBaud, which corresponds to a
maximum cable length of 1.2 km, (see also chapter 6.7, page 39).
• The transmission cable must be terminated at both ends (and only at the ends) with
matching resistors. The matching resistors are integrated and can be switched on or off
at the control panel. Correct functioning of the 2-wire connection can only be secured
through the use of these integrated matching resistors. No external resistors may be
used!
• The loop resistance of the transmission cable may not exceed 100 Ohms in 2-wire
operation.
• Up to 16 summators can be connected to a single bus segment. If the matching
resistors have been correctly installed (see above), if spur line lengths have been
minimized and if the overall loop resistance of the transmission cable is less than 100
Ohms, up to 32 summators can be operated within a single segment.
• User statistics can be queried via the control panel (instrument status).

Bus Left, Bus Right
Each summator is equipped with 2 complete ECS LAN interfaces. They are designated
as LAN L and LAN R. Each of these interfaces can be operated with
either 2-wire or 4-wire transmission technology (RS485).
2-Wire
A bus system, by means of which several summators are connected to the same bus
cable, must be laid out with 2-wire technology.
4-Wire
4-wire technology is used where unusually long transmission paths are involved, or
when boosters need to be integrated into the system. In such cases only line-to-line
connection is possible.
Cable Lengths (LAN Bus)
If several summators (up to 16) are to be installed in close proximity to one another
(overall maximum bus cable length of 100 m), a bus connection making use of a
twisted, two conductor cable is recommended. A line-to-line connection with a twisted
four conductor cable is not necessary until the distance between 2 summators is
greater than 400 m (max. 1200 m).

ECS-LAN Terminal Assignments
User Directory
Directory of ECS LAN Users
Each summator automatically generates an internal directory (ECL command: DIR) of all
users connected to the ECS LAN (assuming that unique identification has been
assigned throughout the entire system). Each summator acknowledges its presence to
12
Gossen Metrawatt GmbH
the entire system every 3 seconds with a so-called broadcast message, and all
receiving summators update their internal directories accordingly. If no message is
broadcast for a period of greater than 20 seconds, the summator in question is deleted
from the internal directories of the other summators.
Unique Identification
Each summator within the ECS LAN must be assigned its own unique summator
identification. Up to 255 different, freely selectable identifications can be created.
The following format is used: A, A1 .. A9, B, B1 .. B9, .. , Z, Z1 .. Z4
System-Wide Access to Measurement Data
Example: Total energy from channel 1 at summator D1 is to be queried from
summator A:
<A> D1:Etot 1
3.10 LAN LED (LANL/LANR)
One LED each for bus left and bus right indicates correct operation of the ECS LAN:
• If no ECS LAN users have been connected, the LED does not light up.
• If one or more users are connected to the corresponding bus segment, the LED lights
up.
• If two or more users have the same identification, the LAN LEDs which represent the
users with identical identification blink. Exception: If the summators with identical
identification are connected to the same LAN segment, no decisive error message
occurs. For this reason, the number of summators should always be compared with
the total number indicated in the user statistics (control panel, instrument status)
during instrument installation.
• If the internal matching resistor has not been switched on during bus operation, the
corresponding LAN LED blinks.
3.11 LON Connection
LON is a relatively new type of intelligent bus concept which allows control units,
sensors and actuators to communicate with one another. Rapid, cost-effective wiring is
achieved by means of intelligent decentralization. Each node (user) is equipped with a
neuron chip, and can communicate with all of the other nodes via the LON-Talk
protocol. Data transmission is accomplished with a standardized, twisted, potential-free
two conductor cable, which can be wired either in bus, ring or star configuration (freely
selectable topology!). The electrically isolating FTT10 transceiver used to this end is
protected against polarity reversal and transmits data at a speed of 78 kb per second.
Thus up to 63 additional nodes can be connected to a U1601 summator via the
integrated LON network. During the first phase of completion, bus users include LON
compatible bus meters, as well as input/output modules, gas or water meters etc. at
later stages.
Energy values from the LON meters can be freely assigned to channels K1 ... K64 by
means of differential linking.

Synchronizing-Interval Data Logger
The energy values which have been measured during a given interval can be stored to a
data logger. This interval (duration: 10 s .. 999 hr., default: 15 minutes) is either derived
from system time, or the interval limit is determined with a trigger pulse slope (default:
channel 11). Energy measured during this interval (EINT) is entered into a list along with
the time and the date. The mean power value occurring within the interval (PINT) is
calculated based upon EINT and the duration of the corresponding interval.
Formatting the Data Logger
!
Attention!
The contents of the data logger are deleted during formatting.
The number of records in the data logger depends upon the number of channels. Thus
the data logger can be formatted in accordance with the desired number of channels.
Formatting can only be performed with an interpreter. Data area resolution is also
defined simultaneously (ECL command: FORMAT).
Defining the Number of Records
The format command reserves adequate space for the selected number of channels in
system memory. The greatest possible number of records is thus determined, but not
memory duration which is solely dependent upon the duration of the interval.
Example: Only channels 1 ... 4, channel 17 and channels 21 .. 23 are to be recorded to
the data logger.
<A> FORMAT=1..4+17+21..23
If the format command is called up without parameters, status information is read out to
the data logger. Most importantly, the number of records which can be entered to the
data logger is shown here.
<A> FORMAT = 1...4 + 17 + 21 ... 23
<A> format
Format(0): 8 channels, 26214 records (= 273 days, with a 15 min. interval)
Channels: 1;2;3;4;17;21;22;23
16
Gossen Metrawatt GmbH
Reading Out the Data Logger
Data stored to the data logger can be read out together with time and date either
directly at the instrument’s control panel or via the serial interface with the ECL
command EINT. The following example shows a read-out of all measurement data for
channels 1 through 5 in ASCII format:
<A> Eint/## 1..5 * **
16.04.93;17:45:00;1;0.5;0.75;0.99;1.36
16.04.93;18:00:00;1.01;0.1;0.76;0.80;0.83
16.04.93;18:15:00;0.99;0.48;0.75;1.02;1.28
Querying a Specific Record
Data for a specific date can be read out with the ECL command INDEX. The example
below shows the value from the data logger for channel 1 on 16 April 1993 at 6:15 p.m.
(in clear text):
<A> Index 16.04.93 18h15, Eint/ 1 .
16.04.93 18:15:00 : Eint-863 (01:Motor7) = 0.99 kWh
Data Logger Memory Structure
The data logger is a ring buffer of fixed size which is formatted accordingly. Access is
made with an index number. Index 0 always refers to the current interval, index 1 to the
last interval and index 2 to the interval before the last etc. The ECL command INDEX
transforms a time entry into the corresponding index number.
Ring Buffer
When memory capacity has been used up, the oldest record (the record with the
highest index number) is deleted to make room for the newest record. The interval which
has just been completed is thus assigned index number 1, and the index numbers for all
previous records is increased by 1.
Range of Values for the Data Logger
Limitation of Resolution to Reduce Data Volume
All data registers at the summator are internally 8 bytes wide (64 bit floating point).
However, where the data list is concerned (as of Eint-1), for which overall memory
duration is directly dependent upon available memory capacity, a format with a width of
2 bytes must be used (which results in a loss of accuracy). Since only energy values are
stored to memory (and no power values since these are calculated), standard “0”
formatting results in the following limitation of the range for values:
Range of Values
–0.8191 ... 0 ... +0.8191
–81.91 ... -0.82, +0.82 ... +81.91
–8191 ... -82, +82 ... +8191

Operation (menu displays)
The U1602 micro-summator and the U1603 mini-summator are not equipped with any
display or operating elements. Communications and parameters configuring are
accomplished with ECSwin software. The display which appears in the control panel
mode is identical to the operating menus provided with the U1601 summator.
Extreme caution must be exercised when changing the parameters for the COM1 and
COM2 serial ports.
If the settings are changed, no communication takes place between the PC and the
summator. Only one port should be changed at any given time, so that the summator
can still be controlled with the other. COM2 must be set to ECL or ECL+HP.

out valid data because, for example, it is currently being calibrated (ErrChan 24:
inservice). The in-service function is activated by configuring the in-service feature:
Example: INSERVICE FEATURE = 3
This function is only active per channel in mode 4=LON.

Time / Date
After the time has been entered to the first line, the cursor jumps to the date line. Entries
have an immediate effect on the integrated real-time clock, and for this reason entry
cannot be interrupted. ECL command: TIME/DATE
Station Name
The station name must have a length of between 1 and 8 characters. If no name is
entered, the name “-” is automatically assigned to the station. The following characters
can be used: _ + – 0 ... 9 A ... Z a ... z. ECL command: STATION
Station ID
Each station within the ECS LAN must have its own unique ID. The same ID may not be
used more than once. Up to 255 IDs can be assigned. The ID has a maximum length of
2 characters. If a blank is entered into the character string, the string is truncated as of
the blank when the entry is acknowledged with F4. IDs have the following format: A, A1
... A9, B, B1 .. B9 ... Z, Z1 .. Z4.
Interval
Range of possible entries for the synchronization interval: 10 seconds ... 999 hours
(entry in seconds). ECL command: INTERVAL (ITV)
Interval Source
The synchronization interval can be generated in three different ways:
Time: Intervals are generated based upon the selected interval duration.
Program: An interval is only generated by the ECL command: SYNC=.
Channel 11: A meter input serves as a binary input for the synchronization signal. The
selected pulse duration and pulse edge are taken into consideration.
ECL command: INTERVAL SOURCE (IQ)
Source (tariff source)
Selection of the appropriate tariff T1 or T2 can be made in two ways:
Channel 12: A meter input serves as a binary input for determining the valid tariff. The
selected pulse duration is taken into consideration. The pulse edge parameter is used to
determine which level is assigned to tariffs T1 and T2. If the “+” edge (1) is selected: low
level (0 V at input) corresponds to tariff T1, and high level (24 V) to tariff T2. If the “-”
edge is selected, these relationships are reversed.
Program: The appropriate tariff is selected with the ECL command TARIFF=1 or
TARIFF=2. These commands are only enabled if “Program” has been selected as the
source. ECL command: TARIFFSOURCE (TQ)
Tariff Unit
The maximum length for the tariff unit of measure is 4 characters. The tariff unit of
measure must be at least one character long. ECL command: TUNIT
T Fix Point
Determines the number of places after the decimal point which are used for the display
of incurred energy costs. ECL command: TFIX
Cost Factors T1 and T2
Cost factors are entered in the same way for tariffs T1 and T2.
The cost factor is used to convert energy values into costs. This conversion can be
applied to the total energy registers for tariffs EtotT1 and EtotT2, as well as EtotT1T2.
Cost factors can be entered within a range of 0.000 to 99.999
ECL command: COSTFAC1, COSTFAC2.

Channel Name
Each physical channel can be assigned a name for the purpose of improved
identification. The name need not be unique, unless it is also used as a field name for a
database. The length of the name may not exceed 8 characters, and it must be at least
one character long. ECL command: CHANNEL
Long Name
An expanded channel name including up to 20 characters. ECL command: LNAME
E-Unit, P-Unit
A freely definable energy unit of measure (e.g. kWh) and power unit of measure (e.g. kW)
can be assigned to each physical channel. The units of measure may not exceed a
length of 4 characters, and must be at least one character long.
ECL command: EUNIT, PUNIT
(Channel) Visible
Each physical channel can be made visible or invisible for queries from the control panel
or for “*” - lists during interpreter operation. The function of the channel remains
otherwise unchanged! If, for example, only channels 1 through 3 are visible, values can
only be queried for these channels in the normal display mode, and the instrument
appears to be a 3 channel device. If “Etot*”, is queried during interpreter operation, total
energy is only displayed for these three channels.
If all channels have been deactivated, time and date are displayed in the normal display
mode. These entries are immediately effective and need not be acknowledged.
ECL command: ONOFF
Channel Start/Stop
The acceptance of meter pulses at a given input is controlled with the Start/Stop
function. A channel which has been created by means of t “differential linking” can be
influenced with the Start/Stop function in an analog fashion. Since the binary input
status of the channel is not influenced, undesired counting of binary data can, for
example, be avoided with this function. These entries are immediately effective and
need not be acknowledged. ECL command: STARTSTOP (STSP)

ECL command: CFIX
C-Factor
The following can, for example, be accomplished with this function: The measured
quantity is consumption in cubic meters. This quantity needs to be displayed in the unit
3
of measure standard cubic meters [Nm ], so that a correction factor is required. This (C-
Factor) is thus the desired multiplication factor used for the calculation of the energy
value for a given channel.
Meter Constant
The meter constant can be defined individually for each physical channel. It indicates
how many meter pulses are generated by a connected meter per kWh, and is used in
U-Ratio, I-Ratio
The Uratio and Iratio factor can be defined individually for each physical channel (see
page 7 for calculation formula).
Sign Changes (+, -): Press “<<” (F2) when the cursor is all the way to the left.
Range of possible entries for Uratio and Iratio: 0.000 ... 99999.999
If the Uratio or Iratio factor is set to zero for a given channel, meter pulses can be
disabled for the channel in question. However, it is better to use the Start/Stop function
for this purpose. ECL command: URAT, IRAT
Note
A detailed description on URAT and IRAT is given in the ECL Interpreter and
Command List (3-348-870-03).
P-Factor
The P-Factor can be defined individually for each physical channel (see page 7 for
calculation formula).
Sign Changes (+, -): Press “<<” (F2) when the cursor is all the way to the left.
Range of possible entries for Uratio and Iratio: 0.000 ... 99999.999

LON Channel
The LON user which has been selected with its neuron ID has 8 channels. Channel 5 is
displayed at local channel 1, if channel 1 has been set to the LON mode.
LON Activity
If a LON user malfunctions, all local channels which are used to display LON channels
indicate errors. In this way, the LON channel can be displayed (run) or suppressed
(stopped) without switching off individual channels.
Neuron ID
This is the internationally unique address for a LON user and consists of a 12 place
hexadecimal value. The summator automatically establishes contact with the LON user
which has been assigned to this address. If the local channel has been set to the LON
mode, the suppressed “LON channel” is displayed (channel 5 from the previous
example).
LON Factor, LON Offset
LON user values are scaled to a value of -1 ... 0 ... +1.
The range characteristics can be freely adapted to the measuring task with the
LON Factor and LON Offset parameters. ECL commands: LONFACTOR, LONOFFSET

ECS LAN via COM
If a 4-wire ECS-LAN connection is to be provided via an asynchronous V24 interface, a
new mode is available for the serial interfaces as from V2.48:
LAN-R or LAN-L.
Example: Two devices shall be interconnected in a TCP/IP network at ECS-LAN level.
Two COM servers are used for this purpose which are linked to one device each per RS
232 interface and are interconnected per Ethernet. COM servers transmit signals in a
transparent manner from the RS 232 interface to the allocated COM server.
As soon as LAN-R or LAN-L has been selected by COM-1 or COM-2 in the setup
menu, the ECS LAN data stream is diverted to this COM interface. The interface
parameters baudrate, parity and handshake are now applicable, instead of the ECS LAN
settings which were previously in use.
Recommendation: maximum baud rate (115200 Bd), parity OFF, handshake RTS/CTS.
The selected parameters must correspond to the settings of the connected COM
server, however, they may deviate from those of the opposite terminal, if necessary.
Please note that the now redundant ECS LAN connection should no longer be used.
Please also make sure that the matching resistor for 2-wire parameters configuration is
activated in order to prevent any ECS LAN errors.
Special case: Use of COM and ECS LAN Connection
The ECS LAN connection is not deactivated in the ECS LAN-via-COM operating mode.
Any telegrams to be sent are transmitted both via the associated COM interface and the
ECS LAN interface. Incoming telegrams are processed by both interfaces. Nevertheless,
it is not a star hub configuration as the two interfaces (COM and ECS LAN) cannot “see”
one another.

2-wire connection is normally used (terminals 45 + 46 or 49 + 50), and this is the only
possibility which allows for bus configuration with multiple users at the same bus cable.
In this configuration the first and the last instruments on the bus cable must be
terminated with the internal matching resistors. Proper functioning of the bus is not
possible if the terminating resistors are not activated (Bus LED LAN/L or LAN/R blinks).
For long transmission distances, or if boosters are required, 4-wire connection can be
used (only line-to-line connection is possible). The required terminating resistors are
automatically activated. The default baud rate is 62.5 kBaud.
Note
Additional information on adjusting the interface (parameter type SET... ) is also
provided in the ECL Interpreter and Command List (3-348-870-03).

When the summator is shipped, all of the passwords have been deleted: any user is
able to configure parameters. If this needs to be avoided, passwords can be entered for
5 users:
Enter a password for user 1 first (master). Passwords for other users (2 through 5)
cannot be entered until the password for user 1 has been entered. After the password
for user 1 has been entered, parameters can be changed for a period of 5 minutes if
none of the keys are activated. After this time period, or after an instrument self-test,
password entry is once again required.
Each user can change his password at will.
After the user has logged on with his password, he has only 5 minutes to change his
own password, even if none of the keys have been activated during this time.
If password protection is to be cancelled for all users, user 1 (master) must enter special
password “111111”. The system deletes all passwords and parameters can be
configured by any user.

Firmware Update
The operating system is stored to flash memory. Summator updating is performed on
site via the serial interface.
Required Tools
• PC with serial interface. Notebooks are best suited because they can be operated
without mains power.
• Null modem cable, e.g. GTZ5232000R0001 (RTS/CTS conductors must be used due
Preparation
• Download the new firmware version from our website:
Save it to an empty directory and decompress the files.
• Connect the summator (COM 1) and the PC with the null modem cable.
• Disconnect the LON bus plug from the summator.
The following work steps are required to this end:
1. Abbreviated Instructions
➭ PC: Start the download with the “Update32.exe” program.
➭ Select the desired language.
➭ Select the COM port to which the summator is connected.
➭ Update the bootstrap loader first.
Update > new bootstrap loader
Set the U1601 ... 3 summator to the download mode to this end, and start the
update.
The summator is automatically reset after updating has been completed.
➭ Then update the firmware and the help texts:
Update > update all
Set the U1601 ... 3 summator to the download mode to this end, and start the
update procedure.
Two files are transferred to the summator.
The summator is automatically reset after updating has been completed.
Done!
The summator is once again ready for use.
Note
If you have connected LON users to your summator, the LON LED on the
summator may blink in exceptional cases. If this is the case, the LON nodes
must be reinstalled (see chapter 12.4).
Gossen Metrawatt GmbH
43
2. Complete Instructions
➭ Connect the U1601 ... 3 summator directly to the PC with the GTZ5232000R0001
null modem cable. A hardware handshake is necessary due to the high baud rate, for
which reason the RTS/CTS leads have to be crossed over (see wiring diagram
below).
➭ PC: Start the download with the “Update32.exe” program.
➭ Select the desired language.
➭ Select the COM port to which the summator is connected.
➭ Update the bootstrap loader first.
Update > new bootstrap loader
– U1601 Summator:
The U1601 summator can be set to the download mode in two ways:
• Press and hold the menu key until “SETUP SELECTION” appears.
Press the menu key 4 times until “SETUP-STATION Menu4” appears.
Then press the F5 key = BOOTSTRAP LOADER AND TESTS ...
Press and hold F1 (BOOTSTRAP LOADER) until the bootstrap loader menu appears.
The default value of 115,200 baud has proven itself in actual practice, and should not
be changed.
• Alternative: Press and hold the F1 key and disconnect auxiliary power at the device
(power-up reset). The summator is now ready to receive data.
– U1602 and U1603 Summators:
These summators can be set to the download mode as follows:
• Press and hold the BOOT button with a pencil until the LEDs go out briefly. When the
button is released, the 4 LEDs start blinking. The LED which remains illuminated the
longest indicates the utilized baud rate:
STATUS : 115,200 baud
LAN/L : 38,400baud
LAN/R : 19,200 baud
LON :
9,600baud
The default value of 115,200 baud has proven itself in actual practice, and should not
be changed.
The summator is now ready to receive data.
Start the update procedure with the PC software.
The summator is automatically reset after updating has been completed.
➭ Then update the firmware and the help texts.
Select update > all.
Set the U1601 ... 3 summator to the download mode to this end, and start the
update procedure.
Two files are transferred to the summator.
The summator is automatically reset after updating has been completed.
Done!
The summator is once again ready for use.

Note
If you have connected LON users to your summator, the LON LED on the
summator may blink in exceptional cases. If this is the case, the LON nodes
must be reinstalled (see chapter 12.4).
6.10 Master Reset
A normal reset is executed after interrupting auxiliary power and when the integrated
watchdog is triggered, i.e. neither measurement data nor parameters are deleted.
However, if you would nevertheless like to delete all measurement data and reset the
parameters to their default values, a master reset must be executed using the keypad at
the U1601 summator. This is only possible within the first seven seconds after switching
the summator on. Press and hold the following keys simultaneously for at least three
seconds to this end:
F1 + F5 + MENÜ
Master reset can also be triggered with the following ECL command: SYSRESET = 590.
The master reset is now performed, after which the instrument returns to its normal
display. The following parameters are not effected by the master reset:
ID
Linking of the status relay
Language
Password configuration
LON matching resistor
Baud rate for the RS232 interface

Programming
9.1
General Information
ECL - Energy Control Language
The flexibility of the ECS is based upon programmability of the individual summators
using a programming language which was developed especially for the ECS, namely
ECL or Energy Control Language. See ECL Interpreter operating instructions and
command reference for more details concerning this high level language which is similar
to FORTH, and which is just as easy to learn as BASIC. Thanks to its programmability,
the following, additional system characteristics are made available:
Virtual Channels
Even complex formulas for the creation of virtual channels can be concisely and plainly
formulated as background programs. No predefined patterns get in the was of flexibility.
Programming the Relays
Relay switching may depend upon a multitude of conditions. Any desired conditions,
even conditions which effect more than one summator, can be formulated with ECL.
These conditions are monitored continuously by a background program. A specialized
type of relay output programming might even correspond to a simple form of
energy management ...
Simple Energy Management
Example: If mean power at a given load component exceeds a specified value, the load
component is switched off by activating one of the two relays. Whether or not this shut-
down is desired at all can be determined by the system clock (e.g. nighttime only), by
querying a binary input (e.g. only shut down if high level is applied to input 10) or by
analyzing the power values of additional load components.
Tariff Selection
Highly specialized requirements for switching between tariffs can be fulfilled by means of
time comparison functions with background programs.
Flexible Adaptation to Database-Specific Transmission Formats
Repetitive queries to the database can be set up as normal P programs. Complete
ASCII oriented database formats can also be realized with this type of program. When
the program is started, data transmission is performed in accordance with the desired
format.
Background Programs H0 through H31
32 background programs, H0 through H31, are available. Each program can record up
to 127 characters. The background programs are run continuously, one after the other.
Due to the multi-tasking structure of the operating program, normal operating
sequences are not effected at all by the background programs.
Programs P0 ... P31, Q0 ... Q31
64 programs, P0 through P31, or Q0 through Q31, respectively, record repetitive
command sequences which can then be run simply by opening the corresponding
program. Programs can be nested, and a normal P program can be run as a sub-
program from a background program.
54

Program Names
Names can be assigned to P programs. P programs can be queried system-wide with
the help of such names.
9.2
Parameters Configuration and Data Visualization at a PC
The easiest way to communicate with a summator from a PC is by means of terminal
emulation, e.g. with the help of HyperTerminal. However, the user must be very familiar
with the commands.
ECSwin provides a much more convenient method.
Program features:
ECSwin is used primarily for configuring parameters at U1600, U1601, U1602, U1603
and U1615 summators in an ECS LAN. Beyond this, reading in and visualizing energy
consumption data in the form of measured value tables and graphics (online display) is
supported as well. The 32 bit program (as from version V3.4 x) runs under MS Windows
Vista, 7 (32 and 64 bit), 8 and 10. Connection to U16sxx is possible via TCP/IP or
RS232.
The following functions are provided by the software:
• A dialog box for logging on and configuring access authority
• A dialog box for setting time in the ECS LAN
• A dialog box for configuring summator parameters
• A dialog box for configuring channel parameters
• A dialog box for setting meter readings
• A dialog box for configuring relay parameters
• Transmit user created command sequences to the summator
• A dialog box for generating virtual channels
• Control panel display (including device display, keys and LEDs) for U1600 and U1601
• Ascertainment and graphic representation of the ECS LAN network topology
• Querying and display (as table or characteristic curve) of Intervalic, daily, monthly and
annual energy and power data which have been stored to memory at the summator
• Querying and graphic display of current measured values in data logger format
• Data transmission via modem (maintenance of a dial-up list)
• Terminal emulation

LON Bus System Structure
The most commonly used transmission medium for industrial and building management
applications is twisted pair copper cable, which is used together with the electrically
isolated FTT-10A transceiver. Both of the conductors can be connected to either pole,
and installation is thus reverse polarity protected.
Maximum transmission distances are influenced by the electrical characteristics of the
cable, and the network topology. Utilized cables should comply with the stipulated
specifications in order to prevent interference during communication. Due to the
possibility of reflections, only one cable type may be used in any given bus segment.
Network Topologies:
Bus Topology
(bus terminator at both ends)
Free Topology
(bus terminator at one end)
If a bus structure is used, the components are connected in parallel, one after the other.
A bus terminating resistor must be used at each end. Branch lines may not exceed a
length of 3 meters. Only one bus terminator is required with free topologies, but
transmission distances are limited in this case.
If repeaters are used, the bus signal can be boosted thus increasing maximum possible
transmission distance. Due to response characteristics, only one passive repeater may
be included in any given bus segment. The transition to other physical transmission
media, and/or targeted forwarding of data packets to individual bus segments, is
accomplished by means of routers.
The following recommendation is based upon experience gained by Gossen Metrawatt
GmbH during installation and start-up of LON systems. The environment within which
the cable is laid has a decisive influence on correct cable selection, and must therefore
be taken into consideration during the planning stage. All generally applicable directives
for laying control and telecommunications cables must be adhered to during installation.

Specified values apply to total cable length and are only valid for the FTT-10A transceiver.
11.2 Cable Type
Inexpensive wiring is possible for applications in environments with minimal interference
using the following cable type: JY (ST) Y 2 ea. 2 x 0.8 mm with twisted wire pairs. The
above specified dimension of 0.8 mm refers to the diameter of the wire, which results in
a wire cross-section of 0.5 square mm.
In most cases no shielding is required. It may be possible to eliminate communications
problems occurring in environments with excessive interference by connecting the
shield at one end. If cables are used which contain several wire pairs, it may be
advantageous if the individual pairs are shielded. Special LON bus cable can be used for
highly demanding requirements.
11.3 Bus Termination
Additional bus terminators are required for bus topologies, and where repeaters are
utilized. These can be purchased as auxiliary LON component U1664 in top-hat rail
mount housing. Each unit includes a one-ended and a two-ended bus terminator.

• 8-channel (S0) meter polling module
• 6-channel analog input module
• 6-channel relay output module
U1660
U1661
OCL210
12.1 Network Interface
A so-called binding is generally required in order to enable communication amongst
LON devices. This means that network variable outputs are linked (bound) to network
variables inputs with the help of a tool.
Binding is not required for the U1601, which significantly simplifies installation. The
nodes are addressed via the neuron ID (LON ID). The neuron ID is a twelve digit number
which is printed on the device, and which can be queried via the display at the A2000.
The channel function is configured with the mode command (CMODE). The desired
values are selected with the sub-channel command (LonCHANNEL). Selected values
and any error messages generated by the LON devices are queried cyclically (polling).
12.2 Functions
Acquiring Energy and Power Values (mode: LON, CMODE = 4 LON)
The U1601 continuously acquires meter readings and power values from the LON
devices. A delta value is generated based upon the current meter reading and the
previous value, which is added to Etot and Eint. The current meter reading is stored to
non-volatile memory for use in generating the next delta value. Only positive delta values
are taken into consideration.
Special feature for U1660 and U1661: These devices are not equipped with a non-volatile
memory. If supply power to any given LON data logger is interrupted, it starts counting
again from zero. Meter readings acquired after this point in time are smaller than the
recorded energy value, and thus no delta value is generated. In order to assure that this
energy is not ignored, the first value after a power failure is saved as the previous value,
and is used as a basis for generating the next delta value.
Acquiring Analog Values (mode: LON-ANA, CMODE = 5 LonA)
LON device network variables can also be acquired as analog values. This operating
mode is especially useful for the innumerable values read out by the A2000 and the
DME400. Values are no integrated in this case.
Acquiring Analog Values with Integration (mode: LON-PE, CMODE = 6 L-PE)
If the analog value represents power, energy is calculated by means of integration.
Binary Inputs and Outputs
(mode: LON-INP, CMODE = 7 LonI or LON-REL, CMODE = 8 LonR)
Binary inputs can be queried with the U1660 meter polling module, and the OCL210
relay output module is capable of switching relays.

12.3.8 Multifunctional Energy Meters U228x W1, U238x W1
The new energy meters of the EM228x and EM238x series transmit the primary values
via LON interface. This means for features Q1 and Q9 that the secondary value is
multiplied with the transformer ratio (CTxVT).
This implies for feature Q1, where CT and VT are freely configurable within specified
limits, that the energy value also changes when the product of CTxVT is changed.
Consequently, such a change should only be made in open-circuit mode without any
load applied.

12.4 Reinstalling a LON Device
The following actions are executed when a LON device is installed:
– Find a bus user based upon the entered neuron ID.
– Read out device type.
– Assign net variables to be read in to a summator channel. Each multi-channel device
has only one neuron ID. The channel is selected with the sub-channel parameter.
– For U1660 and U1661: Transmit parameters to the device.
– For energy metering (MODE = LON): Start delta value generation, i.e. the first value is
saved as previous value energyOld. Delta value = energy – energyOld. Energy values
recorded previously by the LON device are not taken into consideration.
Reinstallation of a LON channel is initialized with the LonNEW c = 1 command, or by
changing the neuron ID. Reinstallation of all LON channels is initialized with the
command:
LonNEW ** = 1 or via SETUP / LON / INSTALLATion
12.4.1 Preparing the Summator
Set bus termination at the control panel:
SETUP / LON / TERMINATION = 50 Ohm (SetLON = RA50)
LON network termination is set via TERMINATION:
TERMINATION = open
in case of external termination
TERMINATION = 50 Ohm with free topology
TERMINATION = 100 Ohm with bus topology using two terminators
(branch lines < 3 m).
12.4.2 Preparing the LON Device
Connect the LON terminal at the LON device to the summator.
Connect operating power to the LON device.
12.4.3 Configuration via the Summator Control Panel
• Configure the summator channel:
LON activity = STOPPED
Set the channel mode: MODE = LON (or LON-ANA, LON-PE, LON-INP, LON-REL)
Enter the sub-channel.
Enter the neuron ID of the LON device.
Enter and/or check all other channel parameters.
LON activity = RUN
• If the summator finds the device, the device type is displayed in the left column.
U1661.6 indicates a U1661 device with 6 channels.
Parameters are transmitted to the device, and are read back in the case of the U1660
and the U1661.
U1660: Check METER CONSTANT.
U1661: Check LONFACTOR, LONOFFSET and P-FACTOR.
• Check LON type.
If the type is displayed correctly: Check for channel errors.
Installation is now complete.
If the connected device is not displayed at LON type: Check the LON ID.
If LON type is ??????.?: Check the LON ID, and check LON wiring.
70
Gossen Metrawatt GmbH
Start reinstallation:
By changing the neuron ID. For example, set the first digit to 1, and then back to 0.
Reinstallation of all channels can be initialized via SETUP / LON / INSTALLATion.
Repeat this procedure until the device type is recognized.
12.5 Configuration at a PC with ECSwin Software
• Log on to the desired summator at the terminal.
• Access the “Configure / Channel parameters” menu function.
• Wait until all data have been read in.
• Enter all parameters to the “Meter inputs” index register.
– MConst is transmitted to the device for the U1660 (double check).
– P-FACTOR is transmitted to the device for the U1661 (double check).
• Enter all parameters to the “LON parameters” index register.
– The LON factor and LON offset parameters are transmitted to the device for the
U1661, (double check).
• Transmit data to the summator.
• Data are read back automatically and the LONtype column is filled in (this column has
read-only access). Due to the fact that type recognition via the LON bus takes several
seconds, “???????.?” is sometimes displayed as a type designation. The channel
parameters window should then be exited and reopened.
• Check LON type.
If the type is displayed correctly: Check for channel errors.
Installation is now complete.
If the connected device is not displayed at LON type: Check the LON ID.
If LON type is ??????.?: Check the LON ID, and check LON wiring.
Start reinstallation:
Use the following command for a single channel: LonRE c = 1 in terminal window
Use the following command for a all channels: LonRE ** = 1
Repeat this procedure until the device type is recognized.
12.6 Replacing a LON Device
• Deactivate the affected summator channel
(control panel: MODE = OFF; ECSwin: CMode = 0).
Deactivate all affected channels for multi-channel devices.
• Replace the LON device.
• Enter a new LON ID.
• Reactivate all deactivated channels
(control panel: MODE = LON; ECSwin: CMode = 4).
• Check LON type.
If the type is displayed correctly: Check for channel errors.
Replacement is now complete.
If the connected device is not displayed at LON type: Check the LON ID.
If LON type is ??????.?: Check the LON ID, and check LON wiring.
Parameters are transmitted to the device in the case of the U1660 and the U1661.
Check for parameters configuring errors. Control panel: CHANNEL ERROR menu,
terminal: ErrChan c
Gossen Metrawatt GmbH
71
If a parameters configuring error is detected:
For U1660: Check METER CONSTANT
For U1661: Check LONFACTOR, LONOFFSET and P-FACTOR.
Start reinstallation:
At the control panel: by changing the neuron ID. For example, set the first digit to 1,
and then back to 0.
Reinstallation of all channels can be initialized via SETUP / LON / INSTALLATion.
At terminal window: For one channel with the following command LonRE c = 1
For all channels with the following command LonRE ** = 1
Repeat this procedure until the device type is recognized.
12.7 Additional LON Parameters
• Waiting time for responses:
SETUP / LON / TIMING CODE = 9 (LONSTATTIMing = 9
TIMING-CODE
Waiting time in ms
)
LONSTATTIMing
Waiting time is set for a response with TIMING CODE.
TIMING CODE is an encoded value for the duration of
