Notes:
•
The quantity of expansion RS232C/RS485 communication modules is the total number of FC5A-SIF2 and FC5A-SIF4 connected to the
CPU module.
•
The stability of communication depends on the quantity of the connected expansion RS232C/RS485 communication modules, the
cable length, and the communication speed. If communication is unstable, confirm and adjust those factors.
•
Values indicated in square brackets represent FC5A-SIF2 earlier than version 200.
