Hi everyone, I'm working with EasyModbus TCP on my .NET 5 project that running on Armbian. A strange issue that I found is that when you specify a Unit Identifier above 128 (128 itself or greater) in the serial port the sent data will be like this. 63,6,0,0,0,1,86,27 witch means unit identifier is 63. My code is:
var client = new ModbusClient("COM4") { Baudrate = 19200, StopBits = StopBits.One, Parity = Parity.None };
while (true)
{
try
{
client.UnitIdentifier = 128;
client.Connect();
client.WriteSingleRegister(0, 1);
//Console.WriteLine(client.sendData[0]);
Thread.Sleep(100);
}
catch (Exception)
{
}
}

You mean client.DataBits = 8? Databits property is not present in ModbusClient.
You can change the databits property in the COM4 serialport properties.

Did it work?
Did it work?
I'm not at work until Saturday. I should test it on Saturday. Also, I have to find a way to set data bits to 8 on Armbian too. That's my final destination and need to work there. Anyhow, thanks for your quick replies.
