Lifecycle status. ABB lists PM861AK01 as a Classic-lifecycle CPU with replacement available and identifies PM858 among the newer controller series for PM861A/PM864A migration.
Migration conditions. ABB states that PM858 and PM862 can be used from System 800xA 6.0.2 and that both processor modules in a redundant pair must be the same type. Confirm the exact replacement package in the ABB lifecycle plan for the installed project.
Executes control applications and manages local, optical and CEX-Bus resources in an AC 800M controller station.
Supports paired CPUs where loss of the primary processor should transfer control to the healthy partner.
Capture LEDs and controller diagnostics, then check power, firmware/project compatibility, baseplate and bus termination.
Verify both processors are the same approved type and inspect RCU-Link hardware and redundancy synchronization.
Separate CPU, Ethernet, CEX-Bus and ModuleBus symptoms before replacing the processor; each path has its own diagnostics.
Amikon can review the exact part number, installed system, quantity, destination and required date before quotation.
Independent multi-brand support for maintenance, outage and legacy-system requirements.
These models are listed only as independent sourcing references. They are not substitutes for PM861AK01. Compatibility, configuration and stock must be confirmed separately for each item.
