3.5.2.6 Upgrade of a redundantly configured automation system
Objective
The PO volume is to be increased for a redundantly configured automation system.
Requirements
● You can access the CPU for which you want to perform the PO upgrade with the engineering
station via a PCS 7 project.
● The CPUs for which you want to upgrade the system expansion card are switched on and
functional. Making the preparations does not depend on the CPU operating mode.
● The PO volume on the System Expansion Cards of the CPUs is evenly distributed.
Basic procedure
1. Using CPU 410 Expansion Packs, create the PO-Activation-File for both CPUs at the
desired PO volume.
You can find information on this in the following sections:
– Section "Ordering an upgrade for a CPU 410-5H (Page 53)"
– Section "How to prepare for the upgrade of the System Expansion Card (Page 54)"
2. Perform the upgrade for this automation system.
You can find information about this in the section "How to perform the upgrade of the System
Expansion Card (Page 58)".
3.5.2.7 Upgrade of a redundantly configured automation system for CPUs with different PO
volumes
Example
In a redundantly configured automation system, a CPU 410-5H is irreparably damaged (due
to water damage, for example).
You want to restore the system using new hardware.
Initial state:
● CPUs with different PO volumes are available (for example, 100 PO and 800 PO).
● Redundant operation of the automation system is not possible because different PO
volumes are licensed on each of the System Expansion Cards of the CPUs.
Proceed as follows for upgrading the System Expansion Cards.
