Product Overview

The ABB PM862K01 3BSE076940R1 is a processor-unit package for the AC 800M controller platform. It combines a PM862 CPU with the items required for the standard K01 configuration and is intended for rail-mounted industrial control installations. The processor uses an MPC866 device operating at 67 MHz. It provides 32 MB of memory, including 23.521 MB available for control applications. ABB specifies an execution time of 0.18 ms for 1,000 Boolean operations, while application-program cycle times can be configured down to 1 ms. Two RJ45 Ethernet channels connect the controller to the Control Network. The baseplate also provides two serial interfaces: COM3 for general RS-232C communication and COM4 as an isolated connection for configuration tools. CEX-Bus and ModuleBus support allow communication interfaces and distributed I/O resources to be added according to the system architecture.

Application Areas

Frequently Asked Questions

1.What is the difference between PM862K01 and PM862K02?
PM862K01 is the single-controller package associated with article number 3BSE076940R1. ABB describes PM862K02 as the redundant package containing two PM862K01 configurations. A K01 unit supports redundancy-capable hardware, but one K01 package alone does not constitute a complete redundant controller pair.

2.Which software versions support PM862K01?
ABB specifies compatibility with System 800xA 6.0.2 and Compact Control Builder 6.0.0-1 or later. Before installation, engineers should also verify the controller firmware, installed hardware libraries and the compatibility requirements of the existing project.

3.Do the PM862 Ethernet ports operate at 100 Mbit/s?
The two built-in Ethernet interfaces are specified as 10 Mbit/s IEEE 802.3 ports. ABB recommends a 100 Mbit/s switched Ethernet backbone for the Control Network. The port speed and the recommended backbone speed should therefore not be treated as the same specification.
