Dear Experts,

some questions about Profibus.

Actually on our Plant, we are using one profibus Card to communicate with Remote I/O (Wago), valves cluster, frequency converter, and some black boxes (Siemens s7....) via DP/DP Coupler.

My questions: - Is it  possible to add a second PB card, so it will be possible to separate the Black boxes on one Card and the Remote I/O, ... , on the other ?

                       - Adding a new slot, or a new black box , will only need a Download on one card and avoid communication disturbance on the Remote I/O?

                       - Where could I find a clear documentation how to configure the Profibus cards.

Thank you for your help.
