HMI general
 The HMI Basic Panel in the context of the S7-1200 can communicate with up to 4 CPUs.
 Text Displays for the S7-1200 are planned in a future release.
 Compatibility with current HMI Ethernet devices
At present, only the Basic Panels have been system-tested and released in conjunction with WinCC
Basic and the S7-1200. However, other panels can also be connected to the S7-1200 in the context of
WinCC flexible.
 MP277 and 377 panels will talk with the S7-1200. Use WinCC flexible for programming and select
the S7-300 communication channel (Rack 0 - Slot 0) at the start.
