I need to make a system in Visual Studio (C #) that allows me to communicate with the PLC, but at the moment I can not find an alternative to obtain this communication. I was reading the MODBUS TCP / IP cominication, I can not understand.
How would you send the information to a specific PLC register from C # and how to identify that registry?
I would appreciate if someone could guide me on the subject.
Greetings.
