Brief Product Description

ABB PM860K01, part number 3BSE018100R1, is a complete processor unit kit for ABB AC800M controller (Compact Product Suite). The kit includes PM860 CPU module, TP830 baseplate, TB850 CEX-bus terminator, TB807 ModuleBus terminator, memory backup battery and 4-position power plug. It runs real-time multitasking operating system, executes control logic according to IEC61131-3 standard, manages S800 I/O via ModuleBus and CEX-bus. It supports redundant CPU configuration for high availability, multiple communication interfaces to connect with HMI, DCS and fieldbus devices. Built-in hardware self-diagnosis monitors CPU, memory, bus and power status. Fully tested surplus and refurbished ABB PM860K01 (3BSE018100R1) kits are available for legacy AC800M system maintenance, controller replacement and plant automation retrofit projects.

FAQ (Frequently Asked Questions)

• Q: Controller cannot download program or communication failure after replacement?
  A: Verify hardware model matches project configuration, check CEX-bus and ModuleBus terminators, inspect baseplate contact, backup battery status, IP address and engineering station communication settings.
• Q: Does ABB PM860K01 support redundant configuration?
  A: Yes, it supports CPU redundant hot standby. Redundancy setup and commissioning must be completed in Control Builder M software.
• Q: What is the difference between PM860K01 and PM861AK01?
  A: PM860K01 is basic AC800M CPU kit; PM861AK01 has higher processing performance and supports RCU link for extended redundancy.
• Q: What does the complete kit contain?
  A: PM860 CPU, TP830 baseplate, TB850 CEX-bus terminator, TB807 ModuleBus terminator, memory backup battery and 4-position power plug.
• Q: Is ABB PM860K01 (3BSE018100R1) available for new automation projects?
  A: This legacy AC800M processor kit is end-of-life for new installations. Only fully tested surplus and refurbished units are supplied for existing system maintenance and retrofits.
