Connection Parameters Needed for HMI/cMT Products to Communicate with HCFA R Series using EBPro (EasyBuilder Pro)

Introduction

All Maple Systems HMIs programmed with EBPro (EasyBuilder Pro), including every cMT X Series and cMT Series model, are compatible with HCFA R Series. Configure your Controller and HMI/cMT with the following parameters to establish reliable communication.

Supported Series: HCFA R Series
