Hello all, I was wondering how to go about having 2 plc's communicate thru my touch panel. I have a MP-270 touchpanel running WinCC flexible 2005 Advanced. The HMI has a connection to each but neither PLC to the other. Is it possible to have an Input turn on a tag for that connection than have this tag turn on another tag that is read from the second PLC. It seems like an easy idea but I'm stumped.
Thanks,
