ABB HIEE300900R0001 Processor Unit

Product Description

Key Specs

• System Compatibility: Exclusive to ABB Advant OCS platform (compatible with Advant Controller 450/460 racks; requires matching backplane and power supply modules).
• Processing Performance: 32-bit RISC CPU; control cycle time as low as 5ms (for 10k I/O points); supports up to 64k distributed I/O (via Profibus DP/Foundation Fieldbus).
• Memory Configuration: 16MB program memory (non-volatile Flash) + 32MB data memory (SRAM with battery backup); expandable via optional 64MB Flash card (for program backup/data logging).
• Communication Interfaces:
  • 2×Ethernet (TCP/IP, for HMI/SCADA integration; supports ABB Industrial IT protocols).
  • 1×Profibus DP-V1 master (for connecting distributed I/O, e.g., ABB CI801 modules).
  • 1×Serial port (RS232, for local configuration/debugging).
• Power Supply: 24V DC (20-28V DC, redundant input supported); power consumption ≤25W (typical load).
• Env: -10°C~+50°C, 5%-95% RH (non-condensing); IP20 (rack-mounted in Advant OCS cabinets).
• Physical Dimensions: 160mm (W) × 130mm (H) × 220mm (D); weight ~1.8kg (fits standard Advant OCS 19-inch racks).

Core Functions

1. High-Speed Control Execution: Runs complex control strategies (e.g., PID loops, sequential function charts) with deterministic cycle times, critical for process stability in power plants (turbine control) or refineries (reactor temperature regulation).
2. Distributed I/O Coordination: Manages data exchange with remote I/O modules (e.g., ABB AI801 analog input modules, DI801 digital input modules) via Profibus DP, enabling centralized control of geographically dispersed process points.
3. System Redundancy Support: Works with redundant Advant OCS racks (1:1 hot standby) — automatically switches to backup processor within 100ms if primary unit fails, ensuring zero process downtime.
4. Data Management & Logging: Collects real-time process data (e.g., pressure, flow) and logs to external storage (via Ethernet); supports historical data retrieval for process analysis and compliance reporting (e.g., ISO 9001).
5. Fault Tolerance: Built-in self-diagnostics (CPU health monitoring, memory error checking, communication link status) — triggers alarms for anomalies (e.g., I/O module disconnection) and stores fault codes (last 100 events) for troubleshooting.

Core Advantages

1. Mission-Critical Reliability: Redundant power input + hot-standby capability meet the high availability requirements of industries where downtime causes significant losses (e.g., nuclear power, upstream oil & gas).
2. Scalable Performance: Supports up to 64k I/O points and 100+ PID loops, scaling from medium-sized processes (chemical batch plants) to large integrated facilities (combined cycle power plants).
3. Legacy System Compatibility: Maintains backward compatibility with existing Advant OCS modules (e.g., CI800 communication modules), enabling cost-effective upgrades for aging industrial control systems.
4. Secure Data Transmission: Implements ABB’s proprietary communication encryption (for Ethernet/Profibus) to prevent unauthorized access, critical for compliance with industrial cybersecurity standards (e.g., IEC 62443).

Applications

1. Power Generation: Serves as the core CPU for Advant OCS in coal-fired or gas-fired power plants — controls boiler combustion, turbine speed, and grid synchronization to maintain stable power output.
2. Petrochemical Industry: Manages refinery processes (e.g., crude oil distillation) — coordinates distributed I/O for temperature/pressure monitoring and regulates valve positions via PID control to ensure product quality.
3. Water & Wastewater Treatment: Controls large-scale water treatment plants (e.g., desalination facilities) — manages pump stations, chemical dosing systems, and filtration units via distributed I/O, ensuring compliance with water quality standards.
4. Metallurgy: Regulates steel mill processes (e.g., blast furnace temperature control) — executes high-speed control loops to maintain precise process parameters, reducing material waste and improving production efficiency.

Precautions

1. System Compatibility Check: Confirm compatibility with Advant OCS rack model (must be Controller 450/460) and backplane version (v3.0+ recommended); mismatched hardware causes communication failures.
2. Redundant Configuration: When using hot-standby mode, ensure primary/backup processors have identical firmware versions (v5.2+ for optimal redundancy switching); firmware mismatches delay failover.
3. Battery Maintenance: Replace the data memory backup battery (CR2032) every 2 years — low battery causes SRAM data loss during power outages; use only ABB-approved batteries.
4. Wiring & Grounding: Connect redundant power inputs to separate 24V DC supplies; ensure proper cabinet grounding (≤1Ω) to reduce EMI interference (critical for Profibus communication stability).
5. Firmware Updates: Perform firmware updates via ABB’s Control Builder M software (v6.0+) — follow ABB’s step-by-step guide to avoid CPU boot failures; back up programs before updating.
6. Environmental Protection: Install in climate-controlled Advant OCS cabinets (avoid direct sunlight or extreme humidity); use cabinet cooling fans if ambient temperature exceeds 40°C.
