1 Serial Communication
The primary interface used for XVG/eXVG is serial communication, which is the
exchange of data one-bit-at-a time, sequentially, on a single data line or channel.
XVG/eXVG can communicate either in PECC (a propriety standard protocol) or
Modbus protocol via the serial interface.
2 Baud Rate
Baud rate is the speed at which a data line changes its state or the number of times per
second the line changes state. If two serial devices are connected together via direct
cables, then baud rate and bit-per-second are the same. XVG/eXVG Modbus
communication supports baud rates of 9600, 19200, 38400, and 57600.
3 Parity bit
A parity bit is optionally transmitted along with data to help detect data corruption
that may occur during transmission. There are three parity modes available: Odd,
Even, or None. XVG/eXVG Modbus communication default parity setting is Even.
4 Start and Stop Bits
The start bit informs the receiving device that a character is coming; a stop bit
indicates that a character is completed. The start bit is always 0 and stop bit is always
1. Per Modbus protocol requirements, XVG/eXVG Modbus communication employs
1 stop bit in Even or Odd parity mode, and 2 stop bits in None parity mode.
5 Electrical Interface Standards
XVG/eXVG serial communication uses either RS232 for one-to-one connection or
RS485 for a multi-drop capable network.
- RS232 interface uses three wires: transmit, receive, and common (ground) line.
A -3 to -12V signal indicates a 1, a +3 to +12V signal indicates a 0.
Communication is one-to-one, and full-duplex capable. Distance is limited to
50 feet.
- RS485 interface uses two wires: T+/R+ and T-/R-. The RS485 receiver
compares the voltage difference between both lines instead of the absolute
voltage level on a signal line. Communication is half-duplex and up to 32
devices can be connected to a multi-drop network up. Distance is limited to
4000 feet.

Follow RS232 and RS485 standards for wiring and biasing of the communication
bus.
6 XVG/eXVG Modbus Communication Default Settings
The default settings for XVG/eXVG Modbus communication are as follows:
- Baud Rate: 19200
- Parity Mode: Even
- Number of Start Bits: 1
- Number of Stop Bits: 1
- Device Address: 1
7 Protocol
Modbus devices communicate using a master/slave technique, in which only one
device (the master) can initiate transactions. The other device (the slave) responds by
supplying the requested data to the master or by taking the action requested. The
master can address individual slaves or can initiate a broadcast message to all slaves.
Slaves will only return a message to requests that are specifically addressed to them.
However, all slaves will perform the action requested by a broadcast message, but
responses are not returned.
XVG/eXVG Modbus conforms to standard Modbus protocol and support Modbus
Remote Terminal Unit (RTU) mode (ASCII mode is not supported). With RS485, it
is possible to have multiple host masters and XVG/eXVG units on the same network.
However, the following protocol requirements must be observed:
-
-
Only one host master can send a request message at a time.
Each XVG/eXVG unit on the same network must have a unique address.
7.1 General Modbus Frame
Modbus protocol establishes the format for the master request message by placing
into it the device address, a function code defining the requested action, any data to
be sent, and an error–checking field. See Table 1 for a general Modbus frame which
is followed from left to right.

DATA
ERROR-CHECK

7.2 Modbus Transactions
The slave’s response message is also constructed using Modbus protocol. It
contains fields confirming the action taken, any data to be returned, and an error–
checking field.
If an error occurred in receipt of the message, or if the slave is unable to perform
the requested action, the slave will construct an error message and send it as its
response.

7.3 Modbus Register Types
Each Modbus register in the XVG/eXVG is identified by its 4-digit number
address. With XVG/eXVG, the term “register” refers to both Modbus Holding
Registers (read-write) and Modbus Input registers (read-only). The types of
XVG/eXVG Modbus registers are listed in Table 3.

7.4 Modbus Functions
The following Modbus functions are supported by the XVG/eXVG:
- Read Registers (0x03)
- Write Single Register (0x06)
- Write Multiple Registers (0x10)
- Diagnostics (0x08) Query Data sub-function (0x00)
The master can address individual slaves, or can initiate a broadcast message (using
device address 0) to all slaves. Slaves perform the actions requested by the broadcast
messages but will not return a response. Per Modbus protocol, only Write Single
Register (0x06) and Write Multiple Registers (0x10) support broadcast message.

Table 16: General Setup Parameters
9.1.2 Position Interpolation Parameters
The XVG/eXVG Fuel Metering Valve can be configured to operate with a non-linear
stroke profile by adjusting the values in this table. The Position Interpolation Table is a
43-point table, which maps a specific position to a linear demand position point. The first
30 points in the table are spaced at 0.1mA intervals and the remaining points are spaced
at 1.0mA intervals.
17
Download from Www.Somanuals.com. All Manuals Search And Download.
The position interpolation feature is enabled / disabled via the IDM_POSINTTBLEN
setup parameter. The valve will ignore this data in this table and assume a linear stroke
profile when IDM_POSINTTBLEN is disabled. Valid Parameter Interpolation Table
values are in the range of 683.0-3413.0, values are in fixed point IQ8 format (count value
multiplied by 28).

Table 17: Position Interpolation Table Parameters
9.1.3 Stroke Position Parameters
For XVG/eXVG low measurement and flow control accuracy improvement, the CdA
values are calculated based not only stroke position (using stroke- CdA interpolation
table) but also on pressure ratio condition.
The following Stroke Position Table lists default values of fifteen stroke positions that
will be used in CdA values calculation. Table values are (stroke value*224).

10 Write Modbus Application
Software packages that support Modbus protocol could be used to write Modbus
application for the XVG/eXVG. The necessary Modbus functions are Read
Registers, Write Single Register, and Write Multiple Registers.
-
-
All XVG/eXVG Modbus parameters are readable using Read Register
function.
Write to the writeable registers can be accomplished with Write functions and
appropriate password.
User Responsibility
By using the Modbus read and write functions, it is possible to access all of the
XVG/eXVG parameters, features, and functions. The following precautions must
be considered when writing your own Modbus application:
31
Download from Www.Somanuals.com. All Manuals Search And Download.
-
-
-
-
-
Only one host master can send request message at a time.
Each XVG/eXVG unit on the same network must have a unique address.
Adhere to the tables of registers provided and their allowable data range.
Do not attempt to write to any register if you are not sure of the consequence.
Do not write to registers that are for options your XVG/eXVG does not have.
Failure to do so can result in erratic control and/or damage to equipment. Care
must also be taken that the process cannot cause damage to property or injury to
personnel if the wrong commands are sent due to operator error or equipment
malfunction.
Handling Communication Errors
-
Reading from or writing to a register that does not exist or is currently
disabled will result in a “time-out response”, or in other words, the
XVG/eXVG will not reply with a message.
-
-
Messages with the wrong format, timing, or CRC are ignored.
Writing to a read-only register, writing with out-of-range data, or writing with
improper permission will result in response error messages.
It is the user’s responsibility to handle the error appropriately and determine
whether to resend the message or halt the operation.
-
Following are a few sample procedures for XVG/eXVG Modbus application:

All XVG/eXVG parameters can be uploaded using Modbus Read Registers
function then convert the results into appropriate number representation for display
and monitoring. Model number and part number need to be converted into ASCII
character string. All registers are readable, choose whichever parameters are of
interest and read them.
10.2 Accessing Fault Records Procedure
The following parameters will be used to retrieve the XVG/eXVG fault records.
There are a maximum of 16 records available in the valve. The first eight are
permanent records, the other records are updated on a first-in first-out basis. When
there were 16 fault records in the valve, the oldest non-permanent record will be
deleted when a new fault record is created.

Table 25: Parameters for Gas Constant R and K
Perform the following steps to change gas constant R and K in real-time.
1. Read registers 7518, 7520, and 7008, to get the R, K, and corresponding
measured flow values. Take note of the R and K values for reference. The
only way to restore the default values without a valve close and reset (engine
shutdown) is to write those values into the valve again.
2. Write registers 7518 and/or 7520 with appropriate new values.
3. Read register 7008 to get new measured flow value.
4. Read the registers that are of interest to your application.
5. If desired, save the new R and K value to the valve. Note that the following
SAVE or RESET procedure will CLOSE and RESET the valve.
SAVE Parameters routine:
- Write a password to register 3099.
- Write 1 to register 3033. Wait 100 milliseconds.
- Write 32 to register 3033. Wait 100 milliseconds.
- Write 1 to register 3005. Wait 100 milliseconds.
34
Download from Www.Somanuals.com. All Manuals Search And Download.
- Write 2 to register 3005. Valve will close and reset.
6. To restore the previous R and K values, write the value of R to register 7518
and the value of K to 7520. In case the old values are forgotten and the new
values have not been saved to the valve, reset the valve by turning power off
then on to restore R and K. The following steps will also reset the valve; care
must be taken, valve will close and reset.
RESET valve routine:
- Write a password to register 3099.
- Write 1 to register 3005. Wait 100 milliseconds.
- Write 2 to register 3005. Valve will close and reset.
10.4 Download Parameters
All setup parameters, tables 15-20, can be written when you have the appropriate
password. New parameters can be downloaded to the XVG/eXVG as follows:
- Setup proper write-access level for the parameters.
- Write the new values to the registers.
- Perform Save Parameters routine.
