Posted 22 Jan 2016 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. Share this post Link to post Share on other sites
Posted 12 Feb 2016 You need to use the same sequence number. The sequence is for variable area read. You will need to change the value in section Startup for D202-D203. For example, to read the setpoint, D202=C100 and D203=0300. Here is a list from p.35 in the E5CN Communications Manual. Try a couple to see how it works.
