Emerson 5X00875G01 is a high-performance control processor belonging to the Ovation OCR3000 series, acting as the core component for critical distributed control system (DCS) applications, especially in ultra-supercritical coal-fired power plants. It integrates the processor and IOIC modules into one unit, with an interface supporting up to 16 local I/O branches that it scans in parallel to boost operational efficiency significantly. Equipped with a 64-bit quad-core processor, 4GB DDR4 ECC memory and 64GB SLC SSD, it achieves a 200μs control loop execution and can handle 50,000 I/O points. Its triple modular redundancy architecture ensures 99.9999% availability, and it has hardware – assisted virtualization and encrypted firmware validation to meet ISA – 99 Level 3 security standards. Operating on 24VDC power, it works stably at 0°C to 60°C and is widely used in power and nuclear – related systems for tasks like flue gas desulfurization control and safety – related system communication.
Emerson’s Ovation system is a distributed control system (DCS) specifically designed for the power generation and water/wastewater treatment industries. As a reliable innovation platform, it provides comprehensive control capabilities and powerful system integration. The main components of Ovation system include:
1. Host: It is the core of the entire system, responsible for data processing, storage, and forwarding, as well as controlling the execution of logic.
2. Screen: It is an interface for users to interact with the system, used to display real-time data, alarm information, trend charts, etc., and allows users to set parameters and control operations.
3. Sound system: Provides sound alarm function. When the system detects abnormal situations or faults, it will emit sound prompts through the sound system, so that operators can respond in a timely manner.
4. Projector: In some applications, it may be used for large screen display, allowing multiple people to simultaneously view system status and operation information.
5. Touch devices: such as touch screens, provide an intuitive operating interface, allowing users to easily perform various controls and settings.
6. Control system: including control logic, algorithms, and strategies, used to achieve precise control of industrial processes.
7. I/O modules and interfaces: used for connecting and exchanging data with external devices such as sensors, actuators, etc. These modules can convert signals from external devices into digital signals that the system can recognize, or convert control signals from the system into instructions that external devices can execute.
8. Communication and network equipment: Ensure data communication and information sharing between internal components of the system and between the system and other external systems.
9. Software and firmware: including operating systems, control software, databases, etc., to provide necessary support and guarantees for the normal operation of the system.
