Industrial Control Network and Firmware Compatibility
The ABB PM867K02 operates as an AC 800M controller processor with redundant CPU capability and high-integrity execution functions. Therefore, it manages application programs, controller tasks, and I/O communication through the AC 800M architecture.
The processor supports two Ethernet channels for control network communication and uses MMS and IAC protocols for controller data exchange. Additionally, the module supports CEX bus communication expansion with up to 12 communication modules.
The PM867K02 provides firmware storage through an 18 MB Flash PROM and maintains controller configuration through battery-backed memory functions. Furthermore, its redundant configuration supports a maximum switch over time of 10 ms for controller continuity.
The module supports ABB industrial control architecture requirements, including backplane bus communication velocity, Profinet or Ethernet-based deterministic industrial networks through compatible communication interfaces, and I/O density scaling within AC 800M Modulebus configurations.
Frequently Asked Questions
Q: Does the PM867K02 support CPU redundancy configuration?
A: Yes. The PM867K02 supports redundant controller operation and provides a maximum redundancy switch over time of 10 ms.
Q: What power supply range does the PM867K02 require?
A: The processor unit requires a 24 V DC supply with an operating range from 19.2 V DC to 30 V DC.
Q: How many I/O modules can the PM867K02 control through Modulebus?
A: A single PM867K02 supports up to 96 I/O modules, while redundant PM867 configurations support up to 84 I/O modules.
Field Installation Guidelines
Install the PM867K02 on the specified AC 800M mounting base and verify correct mechanical locking before applying power.
Use a regulated 24 V DC supply and confirm polarity before connection. Keep power wiring separated from high-voltage cables and switching circuits to reduce electrical interference.
Connect Ethernet communication cables according to industrial network installation practices. Maintain proper cable routing and grounding methods for shielded communication wiring.
Before commissioning, verify controller firmware compatibility, application configuration, Modulebus addressing, and redundant CPU synchronization status.
Maintain the operating environment within the specified temperature, humidity, vibration, and pollution limits defined by IEC/EN 61131-2.
