Operation
The operation of a CPU 410-5H requires a system expansion card. The system expansion
card specifies the maximum number of process objects that can be loaded to the CPU and
saves the license information in case of a system expansion. The system expansion card
forms a hardware unit with the CPU 410-5H. In redundant operation, two CPUs 410-5H must
have system expansion cards with the same number of POs.
2.5
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 modules (e.g., CPU 410-5H, DP slave interface module IM 153-2)
must be identical. This means that they must have the same order number and the same
product or firmware version.
● Two CPUs 410-5H must have system expansion cards with the same number of POs.
2.6
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 Auto-Hotspot.
