Mitsubishi Melsec FX PLC Setup Information

 Topic: CM333

Pay close attention to the configuration details, and limitations provided in this topic. The Mitsubishi CPU types each have specific communication nuances that must be considered.

This help file includes setup information for the Mitsubishi Melsec FX PLC. It includes two drivers: Mitsubishi FX-1N(C)/2N(C)/3U(C) (CPU) and Mitsubishi FX Series CPU.

The Mitsubishi Melsec FX series PLC all have a one serial communications port to which the C-more connects. The serial communications parameters are fixed for this port, therefore there is no setup in the PLC. The parameters in the C-more Protocol Manager are also fixed with the exception of the Timeout and Poll Time.

The C-more panel is the master by default.

 

Note: Remember to power cycle the PLC after making changes to the communication port settings.
