Rules For The Assembly Of Fault-Tolerant Stations; I/O For Cpu 410-5H - Siemens SIMATIC PCS 7 CPU 410-5H System Manual

Rules for the assembly of fault-tolerant stations

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:
● The CPUs have to be inserted in the same slots.
● Redundantly used external DP master interface modules or communication processors
must be inserted in the same slots in each case.
● External DP master interface modules for redundant DP master systems may only be
inserted in central controllers and not in 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, i.e. they must have the same article
number, product version and - if available - firmware version.
● Two CPUs 410-5H must have system expansion cards with the same number of POs.

I/O for CPU 410-5H

You can use the input/output modules of the SIMATIC S7 with the CPU 410-5H Process
Automation. The I/O modules can be used in the following devices:
● Central controllers
● Expansion units
● Distributed via PROFIBUS DP
● Distributed via PROFINET IO
You will find the function modules (FM) and communication processors (CP) that can be
used with the CPU 410-5H in Appendix Function and communication modules that can be
used in a redundant configuration (Page 335).
