PM891K02 is intended for AC 800M architectures that require a matched redundant PM891 processor pair rather than a single K01 unit.
The package supports controller redundancy with separate data and control links, while each CPU supplies Control Network Ethernet, CEX-Bus expansion, and optical ModuleBus connectivity.
Commissioning should verify software support, both network paths, processor synchronization, cable identity, thermal margin, application restore, and controlled failover behavior.
