Hello, I am using easy modbus to read register from modbus register but after 40100 it gives invalid register error. Where as I have the data in register even above 40100. Please help me. With this.

I think that the prefix "4" in your case means that it refers to a "Holding Register"

That means you should read Holding Register "100". Some Devices address the Modbus Registers in that way.

Even if I send it as 100, it gives me error as above. anything more than 99 gives me error.
