It would seemone way to do this would be to have 2 CPUs S7-200+EM2411, one at the remote station with the WinCC Flexible panel, and one at the central station. You start by programming comms between the 2 S7-200 CPUs over the EM241 modems, and then you could connect serially the remote CPU to the operator panel. Would that be applicable in your project? Hope this helps, Daniel Chartier
