      Classic CPU Replacement Scope

      When replacing PM861A or PM864A, compare firmware, application memory, communication modules, I/O and the complete redundant-controller design.

      Technical notes

      PM862K01 3BSE076940R1 is an ABB AC 800M processor unit built around the PM862 CPU, with a 67 MHz clock, 32 MB RAM and 23.521 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 3BSE076940R1, firmware and control-system version, the ModuleBus/CEX-Bus layout and every redundant-partner detail before installation.

      Firmware, Memory and Project Baseline

      Engineering check: Confirm PM862K01 3BSE076940R1 matches the configured processor type, 67 MHz clock and 32 MB memory. Record firmware, application version and project checksum, then verify that memory allocation is within the documented application-RAM limit.

      Cold-Start and Interface Diagnostic Test

      Acceptance test: Execute a controlled cold start with the approved project. Check task scheduling, retained data, watchdog status, controller communication and any configured CEX-bus interfaces before reconnecting process outputs.

      PRODUCT & ORDER FAQS

      Questions buyers ask about PM862K01 3BSE076940R1

      • Is PM862K01 3BSE076940R1 a complete redundant controller?

        No. PM862K01 is the single-processor package. The CPU is redundancy-capable, while PM862K02 article 3BSE081636R1 is the two-unit redundant package. A second loose K01 should not be assumed to equal the K02 supply scope without checking all redundancy hardware.

      • What changes in the ModuleBus layout when PM862 operates redundantly?

        With a non-redundant CPU, ABB lists one electrical plus seven optical clusters and up to 96 I/O modules. In redundant operation, use seven optical clusters with no electrical local cluster and a maximum of 84 I/O modules. The existing I/O topology therefore determines whether pairing is practical.

      • Which courier can I choose for my PM862K01—DHL, FedEx, UPS, or my own forwarder?

        Please state the delivery address, postcode, desired delivery speed and any collect-account or forwarder instructions. Because the processor package may include a 3.6 V lithium backup battery, Moore confirms the exact contents before comparing DHL, FedEx, UPS or another requested service. The 3-day handling period is separate from carrier transit.

      • How should the 32 MB PM862 memory rating be used for project sizing?

        Use 23.521 MB as the RAM available for application programs and data, not the full 32 MB installed RAM. The project must also meet task-cycle and online-change requirements; having a file smaller than 32 MB alone does not prove that it will run on PM862.

      • How can I request warranty support if my PM862K01 appears to have a hardware fault?

        The one-year independent-supplier warranty review uses the exact 3BSE076940R1 serial identity, pre-installation condition, 24 VDC measurement, LED or boot symptoms and the installed firmware and project version. ModuleBus, serial-port or redundant-configuration incompatibility is investigated separately so it is not automatically recorded as a failed CPU.

      • Are COM3 and COM4 available after PM862 is configured as a redundant pair?

        No. ABB marks both RS-232C interface specifications as non-redundant-configuration only. COM3 is the general port with RTS/CTS, and COM4 is the isolated service port. Plan another communication path if a serial connection must remain active in the redundant system.

      • Does the 0.18 ms Boolean benchmark mean the whole control loop scans in 0.18 ms?

        No. The 0.18 ms value is ABB's benchmark for 1000 Boolean operations. Application cycle time can be configured down to 1 ms, while ModuleBus scanning may be 0-100 ms depending on I/O. Total loop response also includes task, I/O and communication timing.

      • How can stock be verified as the correct PM862K01 package?

        Require clear labels showing PM862K01 and 3BSE076940R1, and confirm the PM862 CPU and supplied baseplate, terminators and backup battery against the quotation. A PM862K02 pair, PM861A/PM864A unit or CPU without its listed accessories is a different supply scope.
