Firmware, Redundancy and Industrial Network Integration

The PM867K01 CPU board integrates a microprocessor, RAM memory, real-time clock, LED indicators, INIT push button, and CompactFlash interface. The controller base plate provides two RJ45 Ethernet ports for Control Network communication and two RJ45 serial interfaces for configuration and service operations.

The PM867K01 supports CPU redundancy functions when configured with compatible redundancy components. The redundancy architecture covers CPU modules, CEX-Bus communication paths, communication interfaces, and S800 I/O connections. The maximum controller switchover time in redundant configuration is 10 ms.

ABB AC 800M High Integrity functionality requires the addition of an SM812 safety module and SIL-certified software. Therefore, the controller supports IEC 61508 and TÜV-certified safety execution environments for combined safety and process control applications.

The module supports firmware flash compatibility within the AC 800M controller environment and provides deterministic backplane communication through the controller architecture. Furthermore, the I/O density scaling supports electrical and optical Modulebus clusters for distributed S800 I/O expansion.

Compatibility applies to ABB 800xA version 6.0.2 and later systems.

Frequently Asked Questions

Q: Does the PM867K01 support CPU redundancy operation?
A: Yes. The PM867K01 supports CPU redundancy configurations with compatible redundancy components covering CPU, CEX-Bus, communication interfaces, and S800 I/O connections.

Q: What communication interfaces are integrated on the PM867K01 controller?
A: The controller provides two Ethernet RJ45 ports for Control Network communication and two RS-232C RJ45 serial interfaces. COM3 supports modem control signals, while COM4 provides isolated configuration tool communication.

Q: Is the PM867K01 suitable for SIL safety applications?
A: Yes. High Integrity operation requires an SM812 module and SIL-certified software. The AC 800M High Integrity platform supports IEC 61508 and TÜV-certified safety control functions.

Field Installation Guidelines

• Install the PM867K01 on the designated AC 800M controller base plate with correct mechanical alignment.
• Verify the 24 V DC power supply polarity before energizing the controller.
• Connect Ethernet communication cables to CN1 and CN2 ports according to Control Network topology requirements.
• Use shielded communication wiring where required by the industrial installation environment.
• Keep RS-232C service connections separated from high-voltage power wiring to reduce electromagnetic interference.
• Confirm CEX-Bus and Modulebus connections before commissioning connected communication modules and S800 I/O units.
• Maintain proper grounding practices for cabinet installation and follow ABB system installation documentation.
• Verify firmware and System 800xA compatibility before controller replacement or migration activities.
