Notes:
•
Use one power supply to power the CPU module and the expansion interface module or expansion interface slave module.
•
When using a separate power supply, power up the expansion interface module or expansion interface slave module first, followed
by the CPU module, otherwise the CPU module causes an error and cannot start and stop operation.
•
Use the optional expansion interface cable FC5A-KX1C for connection between the expansion interface master and slave modules.
•
If the expansion interface cable is disconnected during operation, the I/O modules connected to the expansion interface slave mod-
ule are reset and all I/O points are turned off automatically. Then, turn off the power to the CPU module and the expansion interface
slave module, connect the cable, and turn on the power again.
•
Only one expansion interface module can be used with the CPU module.
•
AC input module, analog I/O modules, expansion RS232C/RS485 communication modules, and AS-Interface master module cannot
be connected to the right of the expansion interface module. When AC input module is connected, the ERR LED on the CPU module
does not turn on. Make sure that AC input module is not connected to the right of the expansion interface module.
