Introduction
All Maple Systems HMIs programmed with EBPro (EasyBuilder Pro), including every cMT X Series and cMT Series model, are compatible with a Mitsubishi FX0S/FX0N/FX1S/FX1N/FX2/FX3SA. Configure your Controller and HMI/cMT with the following parameters to establish reliable communication.
Supported Series: Mitsubishi FX0S/FX0N/FX1S/FX1N/FX2/FX3S/FX3SA
