Product Overview
The ABB PM857K02 3BSE088386R1 is a redundant AC 800M High Integrity processor package for System 800xA control applications. The package contains two complete PM857K01 safety processor units, a TK850 CEX-Bus expansion cable and a TK851 RCU-Link cable. Each PM857 processor operates at 96 MHz and provides 32 MB of memory, including 22.184 MB of application RAM. It completes 1,000 Boolean operations in approximately 0.17 ms and supports a 10 ms application program cycle. The two processors operate as a synchronized primary and backup pair. ABB specifies a maximum processor switch-over time of 10 ms. The memory is mirrored between the controllers and should not be interpreted as 64 MB of combined application memory.

Application Areas
|
Application Area |
Typical Use |
|
Redundant High Integrity Control |
PM857K02 can form the processor layer of a redundant High Integrity architecture when combined with the required SM812 configuration and software. It is suited to applications that require both defined safety logic and processor availability. |
|
Equipment Shutdown and Interlocking |
The redundant processor pair can execute permissives, shutdown sequences and protective interlocks for compact process units or critical equipment. Engineers must include the 10 ms application cycle and connected-device response times in the overall design. |
|
Burner and Combustion Control |
PM857K02 may be used within a properly engineered burner or combustion-control system when the complete project remains within the 128-signal limit. The controller package must be combined with the required High Integrity hardware and software. |
|
Packaged Process and Utility Units |
The controller can coordinate process logic, equipment sequencing and protective functions for skids, utility units and localized process systems. Its redundant arrangement reduces reliance on a single processor. |
Frequently Asked Questions
Q1. What is included in the PM857K02 package?
PM857K02 contains two complete PM857K01 safety processor units, one TK850 CEX-Bus expansion cable and one TK851 RCU-Link cable. Each PM857K01 unit includes a PM857 CPU, TP830 baseplate, TB850, TB807, TB852 and a 4943013-6 memory-backup battery.
Q2. Does PM857K02 provide 64 MB of usable application memory?
No. Each processor has 32 MB of memory and 22.184 MB of application RAM. In the redundant arrangement, application data is synchronized between the processors rather than combined into one larger memory resource.
Q3. Does the 10 ms switch-over time guarantee uninterrupted field operation?
The 10 ms value is ABB’s specified maximum processor switch-over time. Complete system behaviour also depends on task execution, communication recovery, I/O redundancy, field-device response and how the application handles the transfer.
