ABB PM864AK01-eA 3BSE018161R2 Processor Unit Module – Key Functions
1. High-Performance Industrial Control
Dual-core ARM Cortex-R4 CPU (up to 400 MHz) for real-time deterministic control in automation systems (cycle time ≤1ms)
Optimized for ABB’s AC 800M PM8xx series, supporting complex control strategies (PID, motion control, batch processing)
2. Advanced Communication & Connectivity
Multi-protocol fieldbus support:
PROFINET IRT (Isochronous Real-Time) for motion control applications
EtherNet/IP, Modbus TCP, OPC UA for seamless SCADA/MES integration
Dual Ethernet ports (CN1/CN2) with switch functionality for daisy-chaining I/O modules
3. Enhanced Redundancy & Diagnostics
Hot-swappable redundancy (supports CPU, power, and communication redundancy) for fault-tolerant systems
On-board diagnostics (LED status indicators, event logging) for predictive maintenance
4. Cybersecurity & Compliance
Secure boot & firmware signature verification (IEC 62443-4-2 compliant)
Role-based access control (RBAC) for user authentication via ABB Control Panel 800
5. Industrial Applications
Power generation: Excitation control (UNITROL 6000), turbine governor systems
Oil & gas: Safety instrumented systems (SIS), compressor control
Pharmaceutical: Batch process automation (FDA 21 CFR Part 11 compliance)
