Create a sequence program.
To change the output characteristics, write the offset data (BFM#10 to #13) and the gain data
(BFM#14 to #17) in the sequence program, and then turn on the corresponding bit of BFM#9 for
the corresponding channel.
Example: Program for changing the output characteristics of channels 1 and 2 (For FX
PLCs):
X000
M0
T0
FNC224

Transfer the sequence program to change the output characteristics.
Transfer the sequence program, and start the PLC.
After the PLC is started and the output characteristic write command (X000) is turned on, the offset
data and gain data will be written.
Since the offset data and gain data are stored in the EEPROM incorporated in FX
sible to delete the pre-written sequence program.
8
Check the analog output signals
Check that the output analog signals correspond to the set output data.
