System Configuration

This section outlines the system configuration required to use the parallel link function.
You can use the parallel link function in the CPU module using the built-in RS-485 port, communication board, and
communication adapter.
The serial port assignments are fixed to the following numbers, regardless of the system configuration.
■FX5U CPU module
CH4: Communication adapter-2
CH3: Communication adapter-1
CH1: Built-in RS-485 port
CH2: Communication board
Communication device
Built-in RS-485 port
Communication FX5-485-BD
board
Communication FX5-485ADP
adapter
*1 Assign CH3 and CH4 in the order from the adapter closest to CPU module.
In the parallel link, only one channel is available to use for one CPU module.
Serial port Important points for selection
CH1 Since it is built-into the CPU module, there is no
need to add equipment.
CH2 Mounted on top of the CPU module, there is no
change in the installation space requirements.
*1
CH3, CH4 Mount the communication adapter to the left of the
CPU module.
