Introduction
All Maple Systems HMIs programmed with EBPro (EasyBuilder Pro), including every cMT X Series and cMT Series model, are compatible with an Omron C/CQM1 Series. Configure your Controller and HMI/cMT with the following parameters to establish reliable communication.
Supported Series: OMRON C, CPM, CPL, CQM Series (Host Link Protocol)
