DigitalFlow™ XGS868i Programming Manual 125
Appendix C. Programming the XGS868i Using PanaView™
C.6.3 Entering Communications Data
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 present, the XGS868i may also have the standard
RS232 serial interface.
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. In addition, the Model XGS868i can receive and execute remote commands,
using
PanaView software, via this link.
Use the Comm port submenu to set the communications port and MODBUS parameters. While following the
programming instructions, refer to Figure 54 on page 141 of Appendix D, PanaView Menu Maps .
Note:
For a more detailed explanation of the MODBUS interface, refer to Chapter 1, Setting Up MODBUS
Communication s, on page 37.
C.6.3a Setting Up the Serial Port
1. To enter this submenu from the
Global
menu, highlight and double-click on the Comm port option in the center
pane.
2. Enter a Meter Address number between 1 and 254 and click
[Next Item].
The default number is 1.
A meter address is only necessary for communication with the GE Measurement & Control PanaView software. See
the PanaView User’s Manual for more information.
IMPORTANT:
If the meter address or baud rate is changed, communication with PanaView must be re-established with
the new address number.
3. Double-click on the desired Baud Rate (from 300 to 19,200).
If you have the RS485 MODBUS option, proceed to step 4 below. If you have the standard RS232 serial interface, the
meter exits the
Comm port
submenu and returns to the
Global PROGRAM
prompt.
Note:
The XGS868i MODBUS communication settings chosen in the next four steps must match those of the
MODBUS control system.
4. Double-click on the desired MODBUS Baud Rate (from 2400 to 19,200).
5. Double-click on the desired MODBUS Parity (None, Odd or Even).
6. Double-click on the desired MODBUS Stop Bits (1 or 2).
7. Enter the desired MODBUS Address.
The meter exits the
Comm port
submenu and returns to the
Global
window. Click
[Exit Page]
once to return to the Site
Edit Menu , and
[Close]
to exit the Site Edit Menu
.
IMPORTANT:
You must reboot the XGS868i to load the new settings.
