1.9.3 Configuring the Communications Port
The Model XGS868i flowmeter is equipped with an RS232 or an RS485 serial interface. An RS485 option is also
available with MODBUS capability. When the MODBUS option is installed, the XGS868i may still also have the
standard RS232 serial interface.
The meter can be configured with a MODBUS option card for MODBUS communications, a Foundation Fieldbus
option card for Foundation Fieldbus communications, an Ethernet option card for Ethernet communications, or with a
MODBUS/TCP option card for MODBUS communication over the Ethernet, if desired.
Note: To set Fieldbus communications parameters, see Appendix E, Foundation Fieldbus Communications.
The serial port is used to transmit stored data and displayed readings to a personal computer by connecting the meter's
serial interface to the serial port of the PC. Also, the Model XGS868i can receive and execute remote commands, using
PanaView software with this link.
COMM
Use the
submenu to set the communications port and MODBUS parameters. While programming the meter,
refer to Figure 31 on page 80.
1.9.3a
Setting Up the Serial Port
Use the steps below to configure the communications port:
1. In the Keypad Program, scroll to PROG and press [Enter].
2. In the PROG menu, scroll to GLOBL and press [Enter].
3. In the Global PROGRAM menu, scroll to COMM and press [Enter].
4. Enter a Meter Address (between 1 and 127) and press [Enter]. (The default address is 1.)
A meter address is necessary for communication with the GE Measurement & Control PanaView software. See
Appendix C, Programming the XGS868i with PanaView™, or the PanaView™ User's Manual (910-211) for more
information.
IMPORTANT:
If the meter address or baud rate is changed, communication with PanaView must be re-established with
the new parameters.
5. Scroll to the desired Baud Rate and press [Enter]. (Available baud rates extend from 300 to 19,200.)
6. Do one of the following:
•
If you have the RS485 MODBUS option, proceed to Step 1 in Setting Up MODBUS Communications on the
following page.
•
If you have the standard RS232 serial interface, go to Procedure Options on the next page.
