What protocols does your PLC support/implement(a very common one is modbus over TCP)? Or are you responsible for writing this as well? Are you comfortable with working directly with sockets, or perhaps your PLC has an API that wraps all the socket stuff for you? More information is required to help you.

What you are asking is basically what I do every day for work so I am more than happy to help!
