4. If your GF868 does not include an option card for MODBUS
communications, you have completed programming the COMM
submenu. However, if you have installed a MODBUS option card,
complete the following steps:
a. Use the keys to select the desired MODBUS Baud
[F1]-[F3]
Rate from three selections: 2400, 4800 and 9600.

Note: If you change any of these MODBUS options, you will need to
power down your meter and power up again to load the
changes into the MODBUS option card.
After completing the above steps, the meter returns to the User
Program. Continue as follows:
•
To continue programming the meter, refer to the menu maps in
Appendix A and navigate to the desired menu. Then, proceed to
the appropriate section of this manual for instructions.
•
To leave the User Program and retain the previous settings,
press [EXIT] and then press
programming changes will be discarded and you will be
returned to the data display.
•
To leave the User Program and return to measurement mode,
press and then press
[EXIT]
Your programming changes will be entered into the meter's
memory, and you will be returned to the data display.
To request specific parameters from the GF868 via the MODBUS,
the control system must enter the appropriate register number. Only
registers 1 through 90 are available for MODBUS communications,
while registers 508 through 512 are used by the GF868 to store the
MODBUS parameters. For details, see Table 1-7 on the next page.
Note: If you request Ch2 or AVE data from a 1-Channel meter, the
values will all be zero.
