Why is the CPU grayed out in the target system when doing an Online Upgrade with CPU 410 Expansion Packs via the Automation License Manager (ALM)?
Requirements for the Online Upgrade function
A CPU version that supports the Online Upgrade function must be configured and it must have the corresponding firmware version:
- CPU 410 Expansion Pack (PO): CPU firmware V8.1 or higher
- CPU 410 Expansion Pack (PN Red): CPU firmware V8.2 or higher
If a CPU version that supports the Online Upgrade function is configured (hardware requirement fulfilled), but the firmware version of the CPU is lower than required, the CPU is grayed out in the target system and can therefore not be selected.
To be able to use the Online Upgrade function you must configure the firmware version of the CPU required as minimum and load it into the CPU. Then, when connecting, the CPU is no longer grayed on the target system and can be selected for an upgrade with an Expansion Pack.
