Official Package Contents
Redundant Wiring, I/O & Diagnostics01Link the CPUs Install TK851 between the two RCU-Link connectors and verify both processor status indications. 02Share the CEX-Bus Connect both CPUs to the same CEX-Bus through TK850 or the approved BC810/BC820 arrangement. 03Use optical S800 I/O Connect redundant CPUs to S800 I/O through optical ModuleBus and two TB840 units; do not use the electrical ModuleBus. Applications & Fault ScenariosBackup CPU not availableCheck TK851 continuity, both baseplate supplies, firmware equality, project configuration and controller diagnostics. CEX-Bus segment faultInspect TK850 or BC810/BC820, segment power and communication-interface LEDs; either processor must be able to control the expansion units. Additional Specifications

FAQWhat is included in PM866AK02?Two CPUs, two TP830 baseplates, two TB807 terminators, one TK850 cable, one TK851 cable and two memory-backup batteries; no license is included. How are the CPUs linked in PM866AK02?Use the supplied TK851 RCU-Link cable. Both processors also connect to the same CEX-Bus. Can the electrical ModuleBus be used with PM866AK02?No. Redundant CPUs connect S800 I/O through optical ModuleBus and two TB840 units. What is the switch-over time for PM866AK02?ABB specifies a maximum of 10 ms, with process outputs frozen during the transfer. How should PM866AK02 redundancy be commissioned?Match firmware and application data, verify both baseplate supplies and bus links, confirm primary/backup health, then follow the site-approved test procedure. What should be included in a PM866AK02 RFQ?Provide the part number, quantity, destination, required date, machine/system model, firmware release, installed CEX/I/O arrangement and labels for both CPUs. RFQ for PM866AK02For a faster technical and commercial check, send the installed-part details before the requested ship date. Email Miya Zheng
