Utilizing its dedicated 100 Mbit\/s RCU-Link interface, the primary CPU streams cyclic data updates and execution state mirrors to the backup CPU without impacting main application scan rates. The hardware monitors backplane communication integrity, triggering automatic channel switchover when hardware communication faults are detected across the backplane bus. Firmware compatibility requires system software 800xA 6.0.2 or Compact Control Builder 6.0.0-1 and higher.\u003c\/p\u003e\n\u003ch3\u003eFrequently Asked Questions\u003c\/h3\u003e\n\u003cp\u003eQ: What happens to the process outputs during a CPU switchover event?\u003c\/p\u003e\n\u003cp\u003eA: The redundant CPU pair executes internal memory mirroring via the TK851 RCU-Link cable, allowing the secondary processor to assume control within 10 ms, maintaining uninterrupted signal states on field I\/O channels.\u003c\/p\u003e\n\u003cp\u003eQ: Can an individual PM862 CPU module be replaced while the remaining unit is running?\u003c\/p\u003e\n\u003cp\u003eA: Yes, the redundant processor configuration allows for the removal and replacement of a failed secondary CPU or baseplate component while the primary CPU maintains active execution, provided the RCU-Link and power connections are handled according to standard maintenance protocols.\u003c\/p\u003e\n\u003cp\u003eQ: How does the backup battery protect application software during supply outages?\u003c\/p\u003e\n\u003cp\u003eA: The included 3.6 V lithium backup battery powers the static RAM array during main 24 VDC power loss, retaining system data, user application logic, and real-time clock parameters for the duration of the battery shelf life.\u003c\/p\u003e\n\u003ch3\u003eField Installation Guidelines\u003c\/h3\u003e\n\u003cp\u003eMount the TP830 baseplates vertically on standard 35 mm DIN rails inside an IP20-rated enclosure, providing a minimum vertical clearance of 50 mm above and below the assembly for natural convective cooling. Interconnect the primary and secondary baseplates using the TK851 RCU-Link cable, ensuring the locking mechanisms click into place to maintain high-speed synchronization. Connect the TB807 ModuleBus terminators to the last active positions on the ModuleBus interface to eliminate signal reflection across backplane communication paths. Ground the shield wires of all communication lines, including CEX-Bus extension cables, directly to the panel earth bar using low-impedance grounding clamps to prevent high-frequency noise interference.\u003c\/p\u003e","brand":"ABB","offers":[{"title":"Default Title","offer_id":53054199333176,"sku":"PM862 3BSE081636R1","price":188.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0893\/1616\/3896\/files\/598._ce34a1db-7745-48a5-b028-41b1f3343c9b.jpg?v=1790646246","url":"https:\/\/www.automodulexpert.com\/products\/pm862k02-3bse081636r1-abb-redundant-processor-module","provider":"AutoModuleXpert Ltd.","version":"1.0","type":"link"}
