I am working with an LS Master-K120 PLC.
I have managed to write a simple program and download it to the PLC.
This was done using RS-232 and COM1. This communication is fine. I can upload and download code and parameters.
Now I am trying to connect using an OPC server.
Following the PLC manual's instructions, I modified my serial cable and configured my parameters. Then I added the device using the OPC Server (KEPware), but could not connect.
I found a small application at the PLC manufacturer website called the Cnet frame editor. I also failed to connect with this application. Only timeout errors.
I've sent multiple requests for help here (http://eng.lsis.biz/), but LS has not responded.
If I can figure out how to connect to the PLC using Cnet Frame Editor, I can move on. Until then I'm stuck. I hope someone here has experience with this PLC.
