Can two VM 204 cards talk to each other?



Is it possible to have two VM 204 cards talking directly to one another? What I would like to do is have the inputs of one card connected to buttons which would operate the outputs of another card at a different location. The second card would then send back the status of its inputs to operate the first cards outputs.

If this is possible, how do you do it?

Hopefully this all makes sense. Thanks in advance
