LS Master-K120 PLC - Cnet Communication

3 posts in this topic

Hi 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. Now I am trying to connect using an OPC server. I happen to be using KepServer. Following the PLC manual's instructions, I modified my serial cable and configured my parameters. Then I added the device using KepServer, 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 checked and double checked my basic parameters (station number, baud rate, parity, data/stop bits). I've sent my question multiple times 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'm really banging my head. I hope someone here has worked with this PLC.

Hello, I am playing with this card G6L-CUEB at the present and looked at the frame editor. When the switch is set to 3 and the defaults are used the card outputs: 02 41 42 43 44 45 46 47 48 49 4A 4B 4C 4D 4E 4F 50 03 02 50 4F 4E 4D 4C 4B 4A 49 48 47 46 45 44 43 42 41 03 over and over. So, the default serial settings are 38400, 8N1. It appears you can construct frames and send/receive to the card. Doubling clicking on a frame brings up the editor. The frames can be saved and loaded. I have not been able to find any pre-created frames. I am adding support for the Master-K protocol to PeakHMI. I was unaware that Kepware supported Master-K. It is not listed on their website. More investigations. Cheers, Mark http://www.peakhmi.com/
