وصف
ABB 3BSE018150R1 PM864K01 Processor Unit Kit
The ABB 3BSE018150R1, also cataloged as the PM864K01 Central Unit, operates as a dedicated processor hardware component for control execution, memory management, and communication processing within the ABB AC 800M System 800xA controller platform.
The PM864K01 processor unit provides CPU execution, controller communication handling, and application processing functions inside the ABB AC 800M automation architecture. Furthermore, the unit integrates termination accessories required for CEX-bus, ModuleBus, and RCU-Link communication paths.
The processor kit includes the PM864 CPU module with TP830 mounting baseplate and dedicated bus termination components. Therefore, system engineers can install the assembly directly into compatible AC 800M controller configurations without separately sourcing standard termination hardware.
The ABB controller architecture uses backplane and bus communication mechanisms for module interaction. In addition, firmware and control software compatibility must be verified before replacement activities, especially when upgrading from previous PM864 configurations to PM864AK01 equivalents.
Backplane Bus Communication and I/O Integration
The PM864K01 supports ABB AC 800M controller communication through internal module buses and external communication interfaces. The included TB850 CEX-bus terminator, TB807 ModuleBus terminator, and TB852 RCU-Link terminator maintain correct electrical termination conditions for connected controller components.
The AC 800M platform supports I/O density scaling through modular expansion structures. Moreover, correct termination installation prevents communication disturbances caused by improper bus impedance or open-ended communication lines.
The processor unit operates as the central execution element, coordinating application logic, controller tasks, and connected I/O modules through ABB industrial control network structures.
Frequently Asked Questions
Q: What components are included with ABB 3BSE018150R1 PM864K01? A: The kit includes the PM864 CPU, TP830 baseplate, TB850 CEX-bus terminator, TB807 ModuleBus terminator, TB852 RCU-Link terminator, memory backup battery, and 4-position power plug.
Q: Can ABB 3BSE018150R1 be used for new AC 800M installations? A: This part is designated as a spare component for systems placed on the market before July 22, 2017. New installations should use the recommended PM866AK01 replacement according to ABB documentation.
Q: What software compatibility applies when replacing this processor unit? A: Replacement with PM864AK01 requires Control Software version 3.2/10 or later. Application modifications are not required when meeting the specified compatibility conditions.
Field Installation Guidelines
Install the PM864K01 processor unit on the designated ABB AC 800M controller mounting structure.
Verify that the TP830 baseplate is mechanically secured before connecting controller modules.
Install CEX-bus, ModuleBus, and RCU-Link terminators according to the system hardware configuration.
Maintain proper separation between power wiring and communication wiring to reduce electrical interference.
Connect the power plug using the approved ABB wiring arrangement and verify polarity before energizing.
Confirm controller firmware and Control Software compatibility before commissioning replacement units.
Handle the lithium memory backup battery according to applicable transport and disposal requirements.
