Hi All,

Does the A2S-Modem count in the PLC as an Intelligent Module or does it have no interface with the PLC other than looking pretty....its connected to a RS232 card that sits in the rack as well. Im hoping its there to look pretty and is not adding to the intelligent module count as i'm up to 5 modules now and I need to add a profibus module.
