Hi Olis,

Hmm. I was expecting full article, pictures, screenshots and code handed to me on the golden pillow.

I just go through the same. Did you manage to solve it?

I found that library for Modbus.

And this one for MDP.

Look like it is going to be a lot of fun. I have an access to the full Beckoff system for development period. Just don't really want to break it. Only £3,500 for the mainboard.
