To set up a 1:1 computer link system using the all-in-one 16- or 24-I/O type CPU module, install an optional RS485 com-
munication adapter (FC4A-PC2) to the port 2 connector. Connect a computer to the RS232C/RS485 converter (FC2A-
MD1) using the RS232C cable (HD9Z-C52). Connect the RS232C/RS485 converter to the CPU module using the user
communication cable 1C (FC2A-KP1C). The RS232C/RS485 converter is powered by an 24V DC source or an AC
adapter with 9V DC output. For details about the RS232C/RS485 converter, see page 26-4.
To set up a 1:1 computer link system using the slim type CPU module, an optional RS485 communication module (FC4A-
HPC2) is needed. The RS485 communication adapter can also be installed on the HMI base module (FC4A-HPH1).
