Writing a 32-bit integer ModbusTCP

[EE_Kraig]

Is there a way to set the PLCAddressKeypad to write a 32-bit integer or do I have to do it in code?

Code: [Select]

string[] data = new string[] { "13", "0" };
modbusTCPCom1.Write("40001", data);

Thanks! IT was the SwapBytes/Words setting that was messing with me.

if your SwapBytes and SwapWords are correct, it should just be:

modbusTCPCom1.Write("L40001", "13");

An important note is that version 3.99v has a bug in the Modbus drivers. You need to either upgrade or apply the driver patch.

Yes, you got me the patch. In this case it was my fault.
