Hi Rossmann, I don´t remember to see "UnitIdentifier" parameter in the tcp methods. Only for rtu. But I´ll double check. Now I´m having another problem, I need a library that works in .net core (UWP application for raspberry Pi 3) Do you know if easymodbus works in .net core? When I create an UWP application and try to reference the DLL it gives me an error.

Hi Shwetha! Thank you for your atention. This is a peace of code that I made for testing purposes and worked fine simulating with modsim32 class Program { static void Main(string[] args) { ModbusClient modbusClient = new ModbusClient("192.168.0.33", 502); modbusClient.Connect(); int[] readHoldingRegisters = modbusClient.ReadHoldingRegisters(200, 1); for (int i = 0; i < readHoldingRegisters.Length; i++) Console.WriteLine("Value of HoldingRegister " + (i + 1) + " " + readHoldingRegisters[i].ToString());...

Hi, I could use easymodbus function to read values from modsim in my computer over tcp. But now I need to comunicate with a device, over tcp also, and it requires a device adress, beyond the Ip adress I need to pass this device adress, but the methods in easymodbus only require Ip adress, port number, start adress and length. I saw that this is a feature in the modbus protocol that some devices implement, like to divide their memory area. Can someonme help me?
