3g3MV with SCU 41 board

[Mesut_yigit 0]

Hi all ; In my recent project , I had to connect 10 3G3MV inverters with an omron CJ1M cpu 21 through a SCU 41 card , but I have no documentation and example to do that. My purpose is to remotely give the start , stop and ramp signals and change the speed reference. Could someone tell me how to do that.

You will need CX-Protocol. You can then write a protocol to communicate with the devices. There are standard protocols with the package to communicate with many Omron devices. These can be used as samples to modify for your device. CX-Protocol will assist in writing communications code for any serial device. It is easy to use. You then use the PMCR function in the PLC to send and receive data.
