Rules for arranging fault-tolerant station components

The following rules have to be complied with for a fault-tolerant station, in addition to the
rules that generally apply to the arrangement of modules in the S7-400:
● Insert the CPUs into the same slots.
● Redundantly used external DP master interfaces or communication modules must be
inserted in the same slots in each case.
● Insert an external DP master interface for redundant DP master systems only in the
central controllers and not in the expansion units.
● Redundantly used modules (for example, CPU 410-5H, DP slave interface module IM
153-2, external DP interface module CP443-5, communication module CP 443-1) must
be identical, which means they must have the same order number and the same product
or firmware version.
