Introduction
All Maple Systems HMIs programmed with EBPro (EasyBuilder Pro), including every cMT X Series and cMT Series model, are compatible with VEICHI VC Series PLC. Configure your Controller and HMI/cMT with the following parameters to establish reliable communication.
Supported Series: VEICHI VC1S, VC1, VC2, VC3, VC5 PLC
