Introduction
All Maple Systems HMIs programmed with EBPro (EasyBuilder Pro), including every cMT X Series and cMT Series model, are compatible with a Mitsubishi FX232/485BD. Configure your Controller and HMI/cMT with the following parameters to establish reliable communication.
Supported Series: Mitsubishi FX0N/FX2/FX2N COM for Communication Module BD FX2N-485-BD, FX2N-232-BD, FX1N-485-BD, FX1N-232-BD, FX3U-485-ADP/BD.
