Configuring Connections
S7 Connections through M7 FMs
For S7 connections established through the internal MPI-/PROFIBUS DP interface,
each S7 connection at the FM requires two connection resources (for two transition
points); at an S7/M7 CPU or C7-600 CPU, one is required in each case (for the
end point).
(1) Available connection resource
(2) Assigned connection resource
(3) PROFIBUS DP
