Re: How can I create Modbus TCP driver for my devices?

Hi
I know there is a built-in WinSock driver within ATEasy.
But my devices only support communication through Modbus TCP which is more than bare WinSock string.
How can I create Modbus TCP driver for my devices? Where should I start from?
Thanks.

Here is some information to get you started on the Modbus protocol.

The basics on sending/receiving through the Modbus Protocol is described here:

Here is an ATEasy ModBus driver. It was developed by a customer and was written for an ActiveX control from "modbustools.com". A link to their web site is below.

The driver is untested by Marvin Test Solutions and provided as-is.
