HWStatus with redundant AC800M
I have redundant PM891 controllers and read status of battery and power supplies A/ B.
When I do this, HwStatus.ErrorsAndWarnings, I assume that I will get the status of
the primary CPU.
Is it possible to read bits 29-31 from the redundant CPU?

For PM866 redundant controller, I could get the RPA at ErrorsAndWarnings Bit 25, RPB at ErrorsAndWarnings Bit 24 and Battery at ErrorsAndWarnings Bit 26.
Guess this will be same for PM891 as well.

For PM891 unit, the following statuses can be detected when executing in a redundant configuration, i.e. when a redundant CPU has been added:
- RPA (16#40060000/16#00000000) - Failure of the redundant power A on the Primary CPU.
- RPB (16#20060000/16#00000000) - Failure of the redundant power B on the Primary CPU.
- CEX bus fuse (16#10020000/16#00000000) - CEX bus fuse on the Primary CPU blown or missing.
- RPA on Backup (16#020A0000/16#00000000) - Failure of the redundant power A on the Backup CPU.
- RPB on Backup (16#010A0000/16#00000000) - Failure of the redundant power B on the Backup CPU.
- CEX bus fuse on Backup (16#008A0000/16#00000000) - CEX bus fuse on the Backup CPU blown or missing.
- Unit B is Primary (16#00000000/16#80000000) - The upper CPU is acting as the Backup CPU and the lower CPU is acting as the Primary CPU.
- Switchover has occurred (16#000E0000/16#40000000) - Switchover has occurred, i.e. the CPU that used to execute as Backup CPU is now executing as the Primary CPU.
- Backup CPU stopped (16#000A0000/16#00000001) - The Backup CPU has been stopped.
