Binary and ASCII protocols

Mitsubishi Electric's communication protocol can be selected from "Binary Code Communication" and "ASCII Code Communication". Binary code communication has a shorter packet length, so it allows for faster communication. Unless there is a specific reason not to, we recommend binary code communication.

For example, if you are using GX-Works3, set it in the network parameter settings.

c_plc_0136

To communicate in binary code, select the binary protocol when selecting the following units.

c_plc_0137
