  2. PMCR with E5CN communication

    Hello all, I would like to read and write values such as Set Value and Process Value from the E5CN via the PLC with SCU41-V1. I have never worked with it before and have limited knowledge to get started. Could anyone please guide me through this? I know PMCR can be used to establish communication, but I am now sure how to get started with it. Also I've set the communication protocol in E5CN as Modbus. Please be kind enough to let me know. Thank you veryy much.
