Rules for arranging fault-tolerant station components

The are additional rules 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 CPUs must be identical, which means they must have the same article
number, product version and firmware version. It is not the marking on the front side that
is decisive for the product version, but the revision of the "Hardware" component
("Module status" dialog mask) to be read using STEP 7.
● Redundantly used other modules must be identical, which means they must have the
same article number, product version and - if available - firmware version.
