- Technical Specifications:
- CPU model: 32 – bit RISC processor, operating frequency 1GHz.
- Memory configuration: 2GB DDR3 SDRAM, 1GB Flash memory.
- Redundancy mode: 1:1 hot standby redundancy, automatic switching time ≤ 100ms.
Detailed content
-
- Working voltage: 24V DC, current consumption ≤ 800mA.
- Working temperature: -20~70°C.
- Communication interface: 2 Ethernet ports (10/100/1000Mbps), supporting Modbus TCP/IP protocol.
- Functional Characteristics:
- Redundant fault – tolerance: The dual – CPU hot standby design ensures that the standby CPU can immediately take over the work when the main CPU fails, without affecting the production process.
- ECC memory: Equipped with error – correcting code memory, which can automatically correct single – bit errors and detect multi – bit errors, improving the reliability of data processing.
- Easy maintenance: Supports hot – swap. The module can be replaced online, and the system will automatically synchronize data after replacement without manual intervention.
- Powerful processing capacity: It can quickly process complex control algorithms and a large number of I/O data, ensuring the real – time performance of the control system.
- Application Scenarios: It is the core control component of the CENTUM VP DCS system, and is widely used in key production processes in industries such as petroleum, chemical, natural gas and power generation. It is used to implement advanced control strategies, logic interlock and data calculation, ensuring the efficient and safe operation of large – scale industrial processes.
