More Information

Overview Manuals Specifications Redundancy Package Capacity Planning Recovery Design

Features:

  • Redundant PM891 package: Two PM891K01 units and the official three-cable link set form the K02 purchasing scope.
  • High application capacity: Each processor provides the documented 450 MHz CPU and 256 MB RAM profile.
  • External backup boundary: ABB documents no built-in backup battery for PM891, so recovery and external backup planning remain project decisions.

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.

Availability is subject to Apter Power's current inventory and sourcing confirmation.

PM891 K02 package boundary

  • Processor pair: Confirm two PM891K01 nameplates and identical approved firmware.
  • CEX link: Verify the TK850V007 extension cable included by ABB.
  • RCU links: Keep TK855 data and TK856 control cables in their documented roles.
  • Excluded hardware: Do not assume a license, BC810K02, or external battery unit is included.

PM891 resource review

  • Application memory: Compare the compiled project and retained-data demand with the approved controller build.
  • Task load: Review peak execution load, task periods, and communication overhead.
  • I/O architecture: Confirm the optical ModuleBus and remote-I/O topology.
  • Cabinet load: Allow for two controllers, link hardware, power demand, and heat dissipation.

Redundant start-up and recovery checks

  • Project archive: Validate a restorable controller backup before the outage.
  • External backup: Document the approved battery or power-continuity strategy.
  • Synchronization: Confirm primary and backup controller states after loading the application.
  • Failover test: Use the site procedure to verify controlled switchover and recovery.
Description
ABB PM891K02 3BSE053242R1 is the redundant PM891 processor package. ABB lists two PM891K01 processor units, a TK850V007 CEX-bus extension cable, a TK855 RCU data-link cable, and a TK856 RCU control-link cable; no license is included.

PM891K02 3BSE053242R1 provides 450 MHz processing and 256 MB RAM per controller, with flash storage, two 10/100 Mbit/s Ethernet channels, optical ModuleBus support, and a maximum documented redundancy switch-over time of 10 ms.

Before ordering PM891K02 3BSE053242R1, verify both processor identities, the approved 800xA release, cabinet power and heat load, external backup strategy, link-cable routing, Control Network design, and application recovery plan.

FAQS

The following is a list of questions commonly asked by our customers. Please contact us if you have a question about our process that is not answered below.
When should PM891K02 3BSE053242R1 be selected instead of PM891K01?
Select K02 only when the approved AC 800M design requires a redundant processor pair and the documented link-cable package.
What must procurement verify in a PM891K02 3BSE053242R1 quotation?
Request both processor units, TK850V007, TK855, TK856, nameplate traceability, required condition, quantity, destination, and delivery target.
How should engineers prepare an application transfer to PM891K02 3BSE053242R1?
Validate the project archive, supported software, firmware, network identities, communication modules, I/O topology, retained data, and rollback procedure.
Why can a PM891K02 3BSE053242R1 pair fail to synchronize after installation?
Check firmware alignment, RCU cable roles, Control Network settings, application state, processor diagnostics, and approved redundancy configuration.
What cabinet checks matter before installing PM891K02 3BSE053242R1?
Confirm DIN-rail space, 24 V DC capacity, heat dissipation, IP20 enclosure protection, grounding, airflow, and link-cable bend clearance.
How should backup power be reviewed for PM891K02 3BSE053242R1?
ABB documents no built-in PM891 battery; verify the approved external backup or recovery strategy for the installed project.
What network records reduce PM891K02 3BSE053242R1 replacement risk?
Preserve both Ethernet paths, IP settings, node identity, time synchronization, switch ports, communication-module tree, and failover test results.
What should be checked if PM891K02 3BSE053242R1 shows high controller load?
Review task periods, event bursts, communication traffic, I/O scan settings, diagnostics, and differences between the approved and restored applications.
