Operating as a non-redundant primary controller, the module scales I\/O density up to 96 I\/O modules per node across local and extended ModuleBus lines. Each TP830 baseplate contains a factory-assigned hardware Ethernet MAC address printed directly on the unit label. On-board memory structures allocate 10.346 MB of dynamic RAM for application tasks, enabling execution speed down to 0.23 ms per 1000 boolean operations across up to 32 parallel control tasks.\u003c\/p\u003e\n\u003ch3\u003eFrequently Asked Questions\u003c\/h3\u003e\n\u003cp\u003eQ: How does the PM860A processor retain user application programs during main power outages?\u003c\/p\u003e\n\u003cp\u003eA: An internal 3.6 V lithium backup battery powers the static RAM array during 24 VDC primary power interruptions, preserving stored application code and system state variables.\u003c\/p\u003e\n\u003cp\u003eQ: What functions do serial communication ports COM3 and COM4 execute on the processor baseplate?\u003c\/p\u003e\n\u003cp\u003eA: Port COM3 operates as an RS-232C serial channel supporting hardware modem control signals, while port COM4 features galvanic isolation designed specifically for local configuration software interfaces.\u003c\/p\u003e\n\u003cp\u003eQ: Can the PM860A processor be configured in a dual-CPU redundant hardware arrangement?\u003c\/p\u003e\n\u003cp\u003eA: No, the PM860A architecture operates exclusively in non-redundant CPU configurations, supporting up to 96 connected I\/O modules.\u003c\/p\u003e\n\u003ch3\u003eField Installation Guidelines\u003c\/h3\u003e\n\u003cp\u003ePosition the TP830 baseplate onto the standard DIN rail and press firmly until the slide-lock mechanism engages. Verify that the rear metal grounding clip establishes direct electrical contact with the DIN rail surface to ensure protective earth continuity.\u003c\/p\u003e\n\u003cp\u003eInstall the TB850 CEX-bus terminator and TB807 ModuleBus terminator into the open extension ports on the baseplate assembly to eliminate signal reflections. Connect incoming 24 VDC control power to the dedicated terminal connections, verifying input voltage stays within 19.2 to 30 VDC. Connect RJ-45 Ethernet cables (CN1, CN2) using shielded twisted-pair conductors, maintaining physical separation from high-voltage motor feeds to prevent electromagnetic noise coupling.\u003c\/p\u003e","brand":"ABB","offers":[{"title":"Default Title","offer_id":52964280140088,"sku":"PM860AK01 3BSE066495R1","price":188.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0893\/1616\/3896\/files\/598._b5b3da16-05cb-43e4-ac85-f9e78a5c7847.jpg?v=1789523517","url":"https:\/\/www.automodulexpert.com\/products\/cpu-processor-unit-abb-3bse066495r1-pm860ak01","provider":"AutoModuleXpert Ltd.","version":"1.0","type":"link"}
