Modbus RTU/TCP Library(.NET5) Fully implemented and debugged next functions: 3,6,16.USE at own risk and responsibility.
Example of use:
1.Init TCP variant
Commutation comms = new Commutation("127.0.0.1", 502, 500); Modbus mdb = new Modbus(comms);
2.Init Serial variant
SerialSettings serialSettings = new SerialSettings(); serialSettings.BaudRate = 19200; serialSettings.DataBits = 8; serialSettings.Parity = System.IO.Ports.Parity.None; serialSettings.PortName = "COM1"; serialSettings.ReadTimeout = 100; serialSettings.stopBit = System.IO.Ports.StopBits.One; serialSettings.WriteTimeout = 100; Commutation comms = new Commutation(serialSettings); Modbus mdb = new Modbus(comms);
3.Data exchange with "slave"
Console.WriteLine("SetINT32: " + mdb.SetINT32(5, -10000000).ToString()); Console.Write("GetINT32 " + mdb.GetINT32(5, out s32val).ToString() + " "); Console.Write(s32val.ToString() + "\n");
where is: bool Set*(register address,data value,optional parametr:"slave" address); return true if operation success
bool Get*(register address,data value,optional parametr:"slave" address); return true if operation success
4.Retrieving errors buffer
foreach(string errorMsg in mdb.GetErrorsList()) { Console.WriteLine(errorMsg); }
