Hello everybody

We have a machine from an Italian manufacturer with a 840D SL controller which we want to connect to the firm’s network. Network etc. is already set up.
Now we just need 2 soft keys that appear in the data input/output area and connected with the paths of the network.
I have seen before that this works and that it’s not too much effort; however I think that the manufacturer’s staff doesn’t quite understand what I want to do.

Has anybody got some approaches?

Many thank in advance
