ABB PM860 Controller Processor Unit

Product Description

The ABB PM860 (3BSE066495R1) is a processor unit for the ABB AC 800M controller platform. It executes application programs, processes control logic, and manages scheduled tasks within the controller. The module uses an MPC860 processor with a 48 MHz clock frequency and 16 MB of memory. Furthermore, it supports up to 32 controller applications and 32 tasks, with application program cycle times down to 1 ms.

Technical Specifications

Processing and Application Capacity

The PM860 uses the MPC860 processor to execute controller applications and process Boolean operations. Its specified performance is 0.23 ms per 1000 Boolean operations. Meanwhile, the controller supports up to 32 applications, with each application accommodating up to 64 programs and 128 diagrams.

In addition, the processor supports 32 controller tasks and 32 different cycle times. Application programs can run with cycle times down to 1 ms, allowing different control tasks to operate according to their configured execution schedules.

Memory and Data Management

The PM860 provides 16 MB of total memory, including 10.346 MB of RAM available for applications and 2 MB of Flash PROM for firmware storage. Flash memory also supports storage functions within the controller.

Furthermore, the built-in 3.6 V lithium battery provides backup for supported controller data retention functions. The specified memory configuration should be considered when checking application requirements and available controller resources.

Power Supply and Controller Synchronization

The module operates from a 24 VDC supply within a specified range of 19.2-30 VDC. Its typical current consumption is 180 mA, with a maximum of 300 mA. Corresponding power dissipation is 4.32 W typical and 7.2 W maximum.

The PM860 also provides a redundant power supply status input for monitoring the power supply condition. However, this feature does not mean that the processor itself supports controller redundancy.

For multi-controller applications, the specified CNCP protocol supports clock synchronization between AC 800M controllers with a synchronization accuracy of 1 ms. In addition, the controller provides an event queue of up to 3000 events per OPC client.

Frequently Asked Questions

Q: Does the ABB PM860 support processor redundancy?

A: No. The PM860 is specified as a non-redundant processor unit. Its redundant power supply status input is a separate monitoring function and should not be interpreted as processor redundancy.

Q: What processor and memory configuration does the PM860 use?

A: It uses an MPC860 processor operating at 48 MHz, with 16 MB of total memory, 10.346 MB of application RAM, and 2 MB of Flash PROM for firmware storage.

Q: What power supply does the PM860 require?

A: The module requires 24 VDC, with an acceptable supply range of 19.2-30 VDC. Its typical current consumption is 180 mA, rising to a maximum of 300 mA.
