ModBus Protocol

Has anyone had experience with communicating to devices using the ModBus/TCP protocol?
I am wanting to create my own driver to use with VB to communicate using this protocol.
If anyone has done any of this let me know thanks!!!

If anyone is interested you can find info on this protocol at:
