Carrier DataPort Description
The Carrier DataPort driver allows the FieldServer to transfer data to and from devices over either RS-
232 or RS-485 using Carrier DataPort protocol. The FieldServer can emulate either a Server or Client.
The DataPort device provides a gateway to CCN devices. This driver polls the DataPort device which in
turn reads data from the CCN devices. Up to 15 system elements may be connected to a DataPort
Device.
Carrier limits the number of CCN devices that can polled from a DataPort Device and also limits the data
that can be transferred between some CCN devices and the DataPort device. For information on these
limitations please consult the Carrier Corporation.
The driver is an active Client driver. This means that it initiates read polls with the DataPort device which
is expected to provide responses. Server functionality is provided by the driver too.
The driver is configured to allow a single Data Table (usually the Display Table) to be read from the CCN
devices via the DataPort device. As the table typically contains more than one data element, the
retrieved data is stored in a number of consecutive Data Array locations in the FieldServer. The driver
can provide descriptions for each of the table values retrieved.
The driver has no advanced knowledge of the CCN devices and their Data Tables. This means that the
driver handles each table in a generic way, without regard for the particular variables that constitute the
tables. The most important consequence of this is that the variable values are stored in the order in
which they appear in the response from the DataPort device. It is not possible to map particular variable
values to particular locations in the FieldServer Data Arrays.

Hardware Connections
The FieldServer is connected to the Carrier DataPort device as shown below.
Configure the DataPort Device according to manufacturer’s instructions. This driver requires that the
DataPort device’s DTPCONFIG table has been configured prior to connection with a FieldServer. In
addition, consult the manufacturer’s information on connecting Carrier Device’s to CCN network.
Note: Typical connections are 9600,N,8,1.

Configuring the FieldServer as a Carrier DataPort Client
It is not possible to complete a configuration for communication with a DataPort device until you are
familiar with the data available from the devices connected to the DataPort. The DataPort device does not
provide a method for discovering the data tables and variables that are available in all the Carrier devices.
Configuring the DataPort driver as a Client is easy; however, you will not be able to complete the server
side configuration until you have a list of the variables and the order in which the DataPort device will
report them. The driver is capable of helping you determine this information but cannot auto-complete the
configuration. This method is discussed in Appendix A.
For a detailed discussion on FieldServer configuration, please refer to the FieldServer Configuration
Manual. The information that follows describes how to expand upon the factory defaults provided in the
configuration files included with the FieldServer (See “.csv” sample files provided with the FieldServer).
This section documents and describes the parameters necessary for configuring the FieldServer to
communicate with a Carrier DataPort Server.
The configuration file tells the FieldServer about its interfaces, and the routing of data required. In order to
enable the FieldServer for Carrier DataPort communications, the driver independent FieldServer buffers
need to be declared in the “Data Arrays” section, the destination device addresses need to be declared in
the “Client Side Nodes” section, and the data required from the servers needs to be mapped in the “Client
Side Map Descriptors” section. Details on how to do this can be found below.

Field / Variable Names
A list of variable names vs. table names vs. equipment types is not provided in this manual. The
reasons for this are that they are not all available to us they can be configured in some devices using
software provided by the Carrier Corporation.
Consult the points list with the literature provided with each type of equipment from Carrier to obtain
variable names. Alternately use the software provided by Carrier to browse the network and
determine the table and variable names.
This driver may also be used to obtain a list of variable names for a given table. On the following
pages are sample Map Descriptors which may be included in the configuration to help obtain this
information. FieldServer recommends that if these Map Descriptors are used to obtain variable name
information, they should be removed from the final configuration as they will consume resource and
processing time.

Appendix A.3.
Map Descriptor Length Explained
The Length parameter is specified as part of the Map Descriptor.
Client Reads:
The length means: “The number of table variable’s whose values are to be stored when the response
is received.” If you do not know the length of the table in advance, set the length to a larger number
(e.g. 100). The driver will process the response; if the table contains more than 100 elements then
some data will be discarded.
Server:
The length parameter is used when the server returns a value that is a string. The length is used to
tell the driver how many characters to extract from consecutive array location to form the response
string. When the server returns a value that is a number, state or time the length should always be 1.
Appendix A.4.
How the Client stores the states/values of the Table Variables.
Discrete States
Appendix A.4.1.
When a Carrier DataPort device reports the state of a table variable which has a discrete state, it
reports the state as a keyword like on/off. This driver converts the keywords to facilitate reading
by other devices.
The driver is programmed to recognize the keywords listed below. The user can add keywords
by specifying additional information in the configuration file.
State Word
CLEAN
DIRTY
HEAT
COOL
ON

If the driver doesn’t recognize the state word, it stores the characters of the state word as decimal
values based on their ASCII value. the number of characters stored is dependent on the length
parameter.
For example, say the driver responds, reporting a variable to be a state ‘INCREDIBLE’. If the
length parameter of the polling Map Descriptor is 1 then the driver stores the first character of the
word incredible; by storing a value of 73 (An uppercase ‘I’ is the seventy third character in the
ASCII alphabet.).
The driver recognizes discrete state words by checking the 1st character of the value field. If it is a
non-digit then it is regarded as a state word. The comparison against keywords in the list is done
without respect for the case of the letters.
Unrecognized Discrete State Words
If the driver does not recognize the discrete state word that has been used it will report the
following error - CarrDP:#24 Err. MD=<MapDesc1> discrete state word not recognized.
The unrecognized discrete word can be found by extracting 10 characters from the line starting at
the 10th character. Once the 10 characters have been extracted they are left and right trimmed
to remove leading and trailing spaces.

Extending the List of Discrete State Words
You can extend the list of state words the driver recognizes by modifying the configuration CSV
file.
The following example adds three state words. If a device reports the state of the variable as
LIGHT then the driver will store the value of 1, if on the other hand the state is reported as DARK
then the driver will store the value zero.

This method may be used to change the values of any of the driver’s default state words by
duplicating the word and specifying a new value in the configuration file.
Appendix A.4.2.
Time Values
If the driver receives a variable value reported in the format hh:mm then the driver stores a
number obtained by multiplying the hours by 60 and adding the minutes. The driver recognizes a
time value by checking the 3rd character for a colon and checking that the 1st character is a digit.
Value_Stored = hh * 60 + mm
E.g. 5:30pm is reported as 17:20 and is stored as 17*60 + 20 = 1040.

Numeric Values
The driver recognizes numeric values by checking the first character of the value field. If it is a
digit then the field is treated as a number.
Appendix A.4.4.
Occupancy Strings / Values
If the value returned for a variable is 8 characters long and each of the characters is a one or a
zero then the driver regards this as an occupancy string an converts it to a binary coded decimal
value and then stores this value.
E.g.: 00101010 = 42 decimal

Appendix B. Trouble Shooting/Connections - Tips and Hints
Appendix B.1.
Connection problems.
Confirm that the device you are trying to attach to the FieldServer is in fact a DataPort device and not
a DataLink device which looks very similar but connects differently.
A DataLink device will require the DataLink driver – FieldServer part # FS-8700-82. Please contact
FieldServer to request an exchange of driver.
Appendix B.2.
Timeouts
Some Data Port tables are long and result in messages of up to 6.5 kB being sent from the data port
to the FieldServer. The default timeout is insufficient in such cases.
In resolving one customer’s connection problems a timeout of 4 s on a table of 134 entries was found
to produce good results.
Please read the notes provided with Error message #25 in section Appendix D of this manual.
Appendix B.3.
Determining Storage Locations
Set the Application parameter to ‘Print_storage_locations’ on the connection to tell the driver to print
messages each time it stores data. The driver dumps messages in the error log reporting the Data
Array name, offset, value and the ‘line’ from which the data was extracted.
Remove the parameter to stop the messages being printed.
Example:
In the line below the driver reports that the line beginning ‘hd_pos_a…..’ was processed and that the
value 0.0 was stored in DA_D2_01 at offset 149.
T02> DPStore:DA=DA_D2_01 Off=49 Val=0.00 <hd_pos_a 0.0

long each table is different. The driver does not know the length of the
responses. The Carrier devices take some time between receiving a poll
and sending a response. The amount of time is proportional to the length
of the response (and hence, to the size of the table.) If the device takes
too long the driver may timeout as the default timeout is 2.0 seconds. It is
strongly recommended that you set the timeout to a large value (like 30
seconds) to start with. The effect of having a large timeout is to
1) allow the driver enough time to receive the response and
2) Increase the amount of time before the driver reports the timeout if
there is a genuine timeout event.
This message is printed when a response is received but the driver did
not find any information in the response that it could use to store. If the
problem occurs repeatedly then take a log and call tech Support after you
have tried the following diagnostic steps. 1) Check connection stats – If
bytes received per message is < 100 then it is likely that the device you
are polling is not responding properly or that a port setting is invalid.
Check the port settings.

Most FST drivers have an input buffer of 3080 bytes This driver has a
buffer size of 16000 bytes. The buffer size is hard coded so you will need
to capture a log and send an error report to FST.
When parsing a response, the driver processes the response line by line.
A single response may consist of a number of lines. Each line is
terminated with a Carriage Return (CR). If a single CR is missing then
the driver sees two lines as a single line. In versions prior to 1.03eA the
driver used the line number as the offset, therefore values extracted from
subsequent lines were stored at the incorrect offset. Now the driver
ignores the corrupted line and advances the line counter by 2 continuing

CR's message #31 will be printed more than once per response. There
is no direct corrective action you can take. The errors arise from dropped
bytes in the response. If the error occurs frequently you will need to

Error Message
Explanation
There DataPort device responded but the response reports an error. The
error number is printed in the message. The message also reports the
name of the node that was polled.
The following 6 errors are documented. For other errors contact the
Carrier Vendor.
#1 Invalid Command : The digit 1 returned as an error code means that
the last ASCII character sent to the DATAPORT by the off-network
device is not one that the DATAPORT recognizes as a command.
#2 No Display Table : The digit 2 returned as an error code means that
the off-network device has commanded the DATAPORT to transmit data
from a controller that is properly configured in the DATAPORT, but the
controller does not contain a point display table.
#3 CCN Bus Communication Error: The digit 3 returned as an error code
means that the DATAPORT cannot transmit data from the requested
controller because
DATAPORT was acquiring data from that controller.
a
communication error occurred while the
CarrDP:#33 Err. DataPort
responded with Err=%d.
Device=%s
#4 Database Full : The digit 4 returned as an error code means that the
off-network device has commanded the DATAPORT to transmit data
from a controller that is properly configured in the DATAPORT, but the
controller is beyond the 900 point limit. For example, if controllers 1
through 10 each contain 90 points, a command for the DATAPORT to
transmit data from controller 11, 12, 13, 14, or 15 will result in error code
4.
#5 DATAPORT Busy : The digit 5 returned as an error code means that
a static data update is in progress, preventing the DATAPORT from
responding successfully to a Send Controller Data Command or a Send
Data Periodically command.
#6 Controller Not Configured : The digit 6 returned as an error code
means that the off-network device has commanded the DATAPORT to
transmit data from a controller that is not configured in the DATAPORT.
For example, if only controllers 1 through 5 are configured in the
DATAPORT, a command of 0 (Send Controller Data for Controller 15)
will result in error code 6.

Driver Stats
The driver reports statistics according to the FieldServer standards. The following notes describe
some aspects of standard statistic reporting which are peculiar to this driver.
•
All error responses from the Carrier DataPort device are recorded as PROTOCOL ERRORS,
In addition to the standard FieldServer communication statistics described above and in the
FieldServer Instruction Manual, this driver can also expose some driver statistics by writing data to a
Data Array. A special Map Descriptor is required. The driver recognizes the Map Descriptor by its
name which must be "CarrierDP-stats”.
The following example shows how this special Map Descriptor can be configured. You can copy this

When the driver sees this Map Descriptor it uses the Data Array DA_CARRIER_STATS (in this
example) to store driver specific statistics. Only one of these Map Descriptors may be specified per
FieldServer.
The driver stores the following data. The location in the Data Array is obtained by multiplying the
port number by 50 and then using the location offset indicated in the table below.
