  • I believe you are asking question in a wrong forum. If you want to connect a PLC from Mitsubishi, that should be in Mitsubishi forums for PLC. They must be publishing SDK/API to connect or there might be some third party SDK available. You can have a look at

  • OPC is the standard approach to communicating with PLCs. OPC provides a .NET library to do so. Please go to their site and download their library. Unfortunately OPC is a third party product so you'll need to get help from them. We can only help with C# specific issues.
