Delphi MODBUS RTU & ASCII Unit, Bibliothek.Delphi Unit supporting Modbus protocol library.SuperCom MODBUS Protocol LibraryMODBUS is an industrial data communication protocol used to control PLC's and automation machines connected through serial lines (RS-232, RS-422, RS-485) or Ethernet TCP/IP connections.
Modbus master on serial and slaves on Ethernet (TCP). Connect a Master Modbus RTU RS232, RS485 with one or more Modbus TCP slaves / servers. Modbus Library.Modbus TCP slave to Modbus Master converter. Yes I understood that Modbus TCp isn't RTU or ASCII over TCP, what I meant is that modbus TCP is like any TCP communication, the only difference is the data structure (right?). I am forced to use modbus and even if I wasn't the situation I am working on makes using modbus the, or a, logical solution.
Thank you very much for your answer, I was looing hope. I would like to start from scratch so libraries are not what I am looking for.What I am asking for is if someone could give me a simple code written in C for a client and/or a server that communicate using Modbus, since I am not sure of what I will be using any type of Modbus would be a great help (RTU/TCP/ASCII).The simpler the better, what I would like the code to demonstrate is, for example: an initialization to the server, a request, an answer, closing the connection.Thank you very much for your time. I am not sure if I want to be using ModBus/TCP, ModBus/RTU or ModBus/ASCII for now.I have searched for client/server examples in C and I could find libraries but no simple example of communication.
