        • PRODUCT OVERVIEW

          What is this product?

          ABB identifies PM866K01 3BSE050198R1 as a 133 MHz PM866 processor unit in the AC 800M controller family. It provides 64 MB RAM, including 51.402 MB available for the application, and uses the MPC866 processor architecture documented by ABB. The unit supports 2 Ethernet channels, up to 12 CEX-Bus communication modules and maximum 96 non-redundant or 84 redundant i/o modules. CPU redundancy and a maximum 10 ms switch-over are supported in a correctly engineered pair. Selection must be based on the complete 3BSE050198R1 article number, CPU type, control-software version and installed bus configuration.

          Source boundary

          Technical values are taken from ABB AC 800M controller and processor-unit documentation. Final compatibility is confirmed against article number 3BSE050198R1, the installed controller nameplate and the project hardware configuration.

      ABB marks PM866K01 Limited and PM866AK01 Active; verify every software, kit-content and redundancy difference before replacement.

      Technical notes

      PM866K01 3BSE050198R1 is an ABB AC 800M processor unit built around the PM866 CPU, with a 133 MHz clock, 64 MB RAM and 51.402 MB available for the control application. ABB documents 2 Ethernet channels, 12 supported CEX-Bus communication modules, CPU redundancy with a maximum 10 ms switch-over, a 24 VDC supply and IP20 construction. Replacement engineering must verify article number 3BSE050198R1, firmware and control-system version, the ModuleBus/CEX-Bus layout and every redundant-partner detail before installation.

      PM866K01 Legacy CPU Confirmation

      Confirm the complete PM866K01 3BSE050198R1 identity, article number 3BSE050198R1, PM866 nameplate, CPU or hardware revision, processor-unit kit contents and the installed redundant controller arrangement. If any marking is unclear, provide close photos of the front label, side label and connections.

      PM866 Limited-Phase Quote Record

      For an accurate quotation, provide quantity, the complete PM866K01 3BSE050198R1 and 3BSE050198R1 identity, nameplate photos, controller software version, CEX-Bus and ModuleBus configuration, redundant partner details, receiving country and required delivery date. Moore Automated will use these records to match the exact processor unit.

      PRODUCT & ORDER FAQS

      Questions buyers ask about PM866K01 3BSE050198R1

      • Which label proves the unit is legacy PM866K01 rather than PM866AK01?

        PM866K01 must show ABB article 3BSE050198R1 and the PM866 designation without the A suffix. PM866AK01 uses 3BSE076939R1. Do not accept the newer A-version name or its article number as an alternate spelling of this legacy unit.

      • Can my PM866K01 be shipped by DHL, FedEx, UPS, or a carrier account I nominate?

        Please tell Moore the destination postcode, preferred service, delivery priority and any collect-account number or forwarding instructions. We first confirm whether the documented 3.6 V lithium memory battery and separate accessories are included, then check the carrier rules and quote DHL, FedEx, UPS or another requested option from the final packed details.

      • Why can a PM866A replacement not be selected only from the common 133 MHz rating?

        The two generations share a 133 MHz MPC866 and 64 MB RAM, but ABB lists 51.402 MB application RAM for PM866 and 51.389 MB for PM866A, with different article identities and lifecycle positions. Verify controller software, firmware, application build and the full redundancy hardware before migration.

      • If my legacy PM866K01 fails during the warranty period, what information should I send?

        Moore Automated's independent-supplier warranty applies to the exact quoted 3BSE050198R1 unit. Retain the nameplate, serial and received-condition photographs and submit the supply, boot, Ethernet and status observations with the installed firmware. An incompatible substitution or unvalidated migration to the A generation is not evidence that the supplied PM866K01 hardware has failed.

      • Is PM866K01 3BSE050198R1 the redundant pair order number?

        No. It is the single PM866 processor package. PM866 supports CPU redundancy, but the legacy redundant package has its own K02 article identity. Confirm both CPU labels, firmware levels and RCU/CEX interconnection parts instead of forming a pair from visually similar units.

      • Why does a 100 Mbit/s control-network drawing not make the PM866 ports 100 Mbit/s?

        ABB specifies the two PM866 Ethernet channels as 10 Mbit/s RJ45 interfaces. The 100 Mbit/s figure is the recommended switched backbone speed. Check switch negotiation and network architecture with the actual CPU port capability.

      • Can the electrical ModuleBus cluster remain when two PM866 CPUs are paired?

        No. The non-redundant arrangement allows one electrical and seven optical clusters with up to 96 I/O modules. The redundant arrangement uses zero electrical and seven optical clusters, with up to 84 modules. Rework the local I/O connection before redundancy if an electrical cluster is present.

      • What does an availability check need to prove for this Limited-generation CPU?

        The stock evidence should show PM866K01, article 3BSE050198R1, PM866 CPU label, hardware/firmware markings and the included baseplate, terminators and backup battery. Because this is the older generation, an offered PM866A or CPU-only item is not the same stock item.
