7.4.2 Communication detail settings

POINT

(1)When the [intelligent function module switch setting] has been set

After writing PLC parameters to the PLC CPU, turn the PLC CPU OFF then back ON again, or reset the PLC CPU.

(2)Connection of multiple GOTs

To some serial communication module models, two GOTs can be connected using both CH1 and CH2.
