Introduction
All Maple Systems HMIs programmed with EBPro (EasyBuilder Pro), including every cMT X Series and cMT Series model, are compatible with a Mitsubishi L6ADP CPU. Configure your Controller and HMI/cMT with the following parameters to establish reliable communication.
Supported Series: Mitsubishi L6ADP CPU RS232 Series Port
