Firmware Flash Compatibility and Industrial Network Execution
The ABB PM867K01 integrates MPC866 processor architecture with 18 MB firmware Flash PROM storage for controller software execution. The module supports AC 800M controller communication through Ethernet-based Control Network protocols including MMS and IAC.
The processor supports deterministic industrial communication requirements through dual Ethernet interfaces and CEX-bus connected communication modules. ModuleBus communication supports distributed I/O handling with configurable scan rates according to connected I/O module quantities.
The controller firmware structure supports up to 32 applications, 64 programs per application, and 32 controller tasks, allowing structured execution of IEC 61131-3 control applications.
Frequently Asked Questions
Q: Does the PM867K01 support redundant controller configuration?
A: The PM867K01 article is specified as a non-redundant processor unit. It supports single processor controller configurations with ModuleBus I/O capability.
Q: What is the maximum current supplied to connected CEX-bus modules?
A: The CEX bus supply current capability is specified as maximum 2.4 A for connected communication modules.
Q: What communication interfaces are available on the PM867K01?
A: The module provides two Ethernet channels using IEEE 802.3 10 Mbit/s RJ-45 interfaces and two RS-232C interfaces for general communication and service tool connection.
Field Installation Guidelines
- Install the PM867K01 on the specified AC 800M controller baseplate and verify mechanical locking before energizing the system.
- Confirm the 24 VDC power supply polarity and voltage range before connection.
- Maintain separation between communication cables and high-voltage power wiring to reduce electrical interference.
- Connect Ethernet and RS-232C cables according to the applicable industrial wiring practices and grounding requirements.
- Ensure protective earth and cabinet grounding are correctly implemented according to the control cabinet design.
- Verify ModuleBus and CEX-bus connections are fully seated before controller startup.
- Operate the processor within the specified environmental conditions, including temperature, humidity, and pollution degree requirements.
