HC800 ABB ontrol Processor Module
Technical Specifications
The HC800 is a powerful, high-density control processor module designed for executing complex continuous, discrete, sequential, and advanced control strategies. It serves as the primary intelligence engine for Symphony Plus SD Series distributed control system (DCS) installations.
-
Processor Architecture: High-speed 32-bit RISC microprocessor (PowerPC architecture) operating at high clock frequencies to handle intensive real-time computations.
-
Memory Configuration: Equipped with 128 MB of volatile RAM for execution data and 16 MB of non-volatile flash memory for secure storage of control logic, firmware, and user configurations without needing battery backup.
-
Execution Capacity: Capable of running thousands of simultaneous function blocks with execution loop cycles as low as 1 millisecond.
-
Network Communication: Seamlessly connects to the 100 Mbps PN800 Fast Ethernet redundant plant network bus for high-speed peer-to-peer and supervisory communications.
-
Local Control Bus: Connects to local I/O modules via the 4 Mbps CW800 Controlway or HN800 high-speed horizontal bus architectures.
-
Redundancy Support: Supports full hardware redundancy. Two HC800 modules can be paired on a shared baseplate for automatic, “bumpless” master-to-backup switchovers in the event of a fault.
-
Form Factor: Housed in a compact, rugged aluminum casing designed for direct vertical mounting on 35mm DIN-rails within standard system cabinets.
Target Industries
The HC800 control processor is deployed globally across heavy process industries that demand non-stop availability:
-
Power Generation: Thermal, combined-cycle, gas turbine, hydroelectric, and nuclear utility plants.
-
Water and Desalination: Municipal water treatment, large-scale desalination plants, and massive water distribution pipelines.
-
Oil, Gas, and Petrochemical: Refining facilities, gas gathering platforms, chemical processing plants, and pipeline compressor stations.
-
Pulp and Paper: Continuous digesters, recovery boilers, and paper machine processing loops.
-
Mining and Metallurgy: Ore processing plants, blast furnaces, and continuous casting lines.
Application Scenarios
The HC800 acts as the central executive hub for plant-wide or localized industrial processes:
-
Closed-Loop PID Regulation: Executing high-accuracy continuous control strategies for pressure, temperature, and flow loops in utility boiler systems.
-
Sequence and Batch Control: Coordinating complex step-by-step logic and timing configurations required for chemical batch mixing or turbine startup sequences.
-
High-Availability Failsafe Loops: Functioning in a redundant controller setup to ensure that a hardware failure will not halt the plant, maintaining full system state continuity across critical processes.
-
Smart Field Telemetry Aggregation: Acting as a localized gateway that processes and digitizes raw inputs coming from thousands of HART, PROFIBUS, or Modbus field instruments and routing them up to the operator workstations.
