Product Overview
The ABB PM861AK02 3BSE018160R1 is a redundant processor-unit package for the AC 800M control platform. ABB identifies the package as two PM861AK01 processor units combined with a TK850 CEX-Bus expansion cable and a TK851 RCU-Link cable. Each PM861AK01 processor unit incorporates a PM861A CPU, TP830 baseplate, TB850 CEX-Bus terminator, TB807 ModuleBus terminator, TB852 RCU-Link terminator and memory-backup battery. The K02 package therefore provides the principal controller hardware required to create a paired PM861A configuration. The PM861A uses a 48 MHz MPC860 processor and provides 16 MB of SDRAM, including 7.155 MB available for control applications. ABB specifies 0.23 ms for 1,000 Boolean operations and application-program cycle times down to 1 ms. In a redundant arrangement, the primary and backup processors are connected through the Redundancy Control Link. ABB specifies a transfer time of less than 10 ms from the primary CPU to the backup CPU. Actual process behavior during the transfer also depends on the application, communication modules, distributed I/O arrangement and controller configuration.

Benefits
• Paired controller architecture for improved system availability
• Defined K02 package for redundant installations
• Predictable execution for established AC 800M applications
• Expandable communication-interface structure
• Support for distributed optical ModuleBus I/O
• Battery-backed application memory
• Compact rail-mounted construction
• Suitable for maintaining an installed PM861A architecture
Application Areas
|
Application Area |
Typical Use |
|
Redundant Process Control |
PM861AK02 can operate sequencing, interlocking and regulation applications where a paired AC 800M controller arrangement is required. Transfer from the primary CPU to the backup CPU is specified at less than 10 ms, although complete process response depends on the engineered system. |
|
Plant Utility Automation |
The controller package can coordinate water distribution, compressed-air, cooling, steam and other utility functions. Separate application tasks can be assigned according to the required execution rate and operating priority. |
|
Distributed Optical I/O Systems |
In a redundant CPU arrangement, PM861A supports seven optical ModuleBus clusters and up to 84 ModuleBus I/O modules. This makes the package applicable to installations where field I/O is distributed across several plant areas. |
|
Production and Material-Handling Control |
PM861AK02 can coordinate conveyors, production sections, equipment permissives and machine sequences within an AC 800M architecture that requires primary and backup processors. |
Frequently Asked Questions
Q1. What is included in the PM861AK02 package?
ABB describes PM861AK02 as two PM861AK01 processor units supplied with one TK850 CEX-Bus expansion cable and one TK851 RCU-Link cable. Each PM861AK01 includes a PM861A CPU, TP830 baseplate, CEX-Bus and ModuleBus terminators, RCU-Link terminator and backup battery.
Q2. What is the difference between PM861AK01 and PM861AK02?
PM861AK01 is a single processor-unit package. PM861AK02 contains two PM861AK01 units and the cables required to establish the controller redundancy links. The two article numbers should not be treated as the same package configuration.
Q3. How should ModuleBus I/O be arranged in a redundant PM861A system?
ABB specifies seven optical ModuleBus clusters and a maximum of 84 I/O modules for a redundant PM861A configuration. The electrical ModuleBus is not listed as an active I/O cluster in the redundant arrangement, so the optical architecture should be reviewed during system design.
