Setting Up Serial
Communications
The Model GS868 flowmeter can transmit stored data and displayed
readings to a remote ANSI terminal or a personal computer by
connecting the meter’s RS232 interface to the serial port of the PC. In
addition, the Model GS868 can receive and execute remote
commands via this link.The meter can also be configured with a
MODBUS option card for MODBUS (RS485) 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
communications over the Ethernet, if desired.
Note:
To set Fieldbus communications parameters, see Appendix D,
Foundation Fieldbus Communications .
Use the
COMM
submenu to set the RS232, MODBUS, Ethernet and
MODBUS/TCP communications port parameters and to enter a
network identification number.T A network identification number is
required to use the GE
Instrument Data Manager or PanaView
software. While following the programming instructions, refer to the
menu map in Figure A-3 on page A-3
.
1.
To enter the
COMM
submenu, press
[F4]
at the
Global PROGRAM
screen.
2.
Use the [
←]
and [
→]
and
[F1]-[F4]
keys to select the desired Baud
Rate. The available rates are 300, 600, 1200, 2400, 4800, 9600 and
19,200 baud.
3.
Use the [
←]
and [
→]
and
[F1]-[F4]
keys to select the number of
UART Bits , as shown in Table 1-11 below.
4.
Enter a Network ID number between 1 and 254 and press
[ENT]
.
The default number is 1.
A network ID number is only necessary for communication with the
GE
Instrument Data Manager or PanaView software. See the
software User’s Manual for more information.
IMPORTANT:
If the network ID number is changed, communication
with the
Instrument Data Manager or PanaView must
be re-established with the new ID number.
