System Configuration

This section outlines the system configuration required to use non-protocol communication.
You can use up to a maximum of 4 channels (FX5UC is maximum of 3 channels) of non-protocol communication in the CPU
module using the built-in RS-485 port, communication board and communication adapters.
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

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.
