Product Overview
The ABB PM891K02 3BSE053242R1 is a redundant processor-unit package for the AC 800M control platform. The package contains two PM891K01 processor units, one TK850V007 CEX-Bus extension cable, one TK855 RCU Data Link cable and one TK856 RCU Control Link cable. Each PM891 is a monolithic controller unit containing its power supply, CPU boards and termination hardware. The processor uses a 450 MHz MPC8270 device and provides 256 MB of memory, including 208.985 MB available for control applications. ABB specifies an execution time of 0.043 ms for 1,000 Boolean operations and application-program cycle times down to 1 ms. The K02 configuration provides primary and backup controller paths. ABB specifies a maximum switch-over time of 10 ms in a redundant configuration. The redundancy architecture can cover the CPUs, CEX-Bus, communication interfaces and S800 I/O when the required supporting components are installed.

Benefits
• High processing capacity for larger control applications
• Paired controller architecture for improved availability
• Large application-memory capacity
• Faster Ethernet connectivity than earlier 10 Mbit/s AC 800M processors
• Integrated construction with reduced external termination hardware
• Scalable CEX-Bus communication expansion
• Support for distributed optical S800 I/O
• Defined data and control links between redundant processors
Application Areas
Application Area
Typical Use
High-Performance Process Control
PM891K02 can execute larger sequencing, regulation, interlocking and equipment-control applications that require more processor performance and application memory than earlier AC 800M controller generations.
Redundant Continuous-Process Automation
The paired processors can provide primary and backup controller paths for production systems where controller availability is an important design requirement. ABB specifies a maximum controller switch-over time of 10 ms.
Large Multi-Application Projects
With 208.985 MB of application RAM, 32 applications per controller and 64 programs per application, PM891 can support control projects containing multiple process areas, operating units and execution tasks.
Distributed S800 I/O Systems
Seven optical ModuleBus clusters can connect up to 84 I/O modules. This arrangement is suitable where control cabinets and field I/O stations are distributed across different parts of a facility.
AC 800M System Expansion
PM891K02 can be used when an installed System 800xA or AC 800M project requires a redundant PM891 controller pair. Mechanical layout, Control Builder version, firmware, CEX-Bus interfaces and application backups should be reviewed before integration.
Frequently Asked Questions
Q1. What components are included in PM891K02?
ABB lists two PM891K01 processor units, one TK850V007 CEX-Bus extension cable, one TK855 RCU Data Link cable and one TK856 RCU Control Link cable. BC810K02 is not included.
Q2. Does PM891 contain an internal backup battery?
No. ABB states that PM891 does not contain an internal battery. Engineers should maintain a verified project backup and confirm the application-storage, cold-retain and recovery strategy before replacing or commissioning the controller.
Q3. When is BC810K02 required with PM891K02?
BC810K02 is required when the design must support hot replacement of a PM891 processor unit. It also provides the sectioned CEX-Bus arrangement used to improve availability with redundant communication interfaces. The kit must be ordered separately.
