Yokogawa offers a range of CPU modules tailored for different control systems, including the CENTUM series Distributed Control Systems (DCS) and the STARDOM network-based control systems. These modules are engineered to meet the demanding requirements of process industries, ensuring seamless integration and optimal performance.
Types:
- CENTUM VP CPU Modules: Utilized in Yokogawa's flagship DCS, these modules provide robust processing capabilities for large-scale process control applications.
- STARDOM FCN/FCJ CPU Modules: Designed for network-based control, these modules offer flexibility and scalability for various automation needs.
Technical Features
-
High Processing Performance:
- The CPU modules for systems like the CENTUM VP are equipped with dual-core processors operating at up to 1.5 GHz, designed to execute complex control algorithms with low latency. In STARDOM FCN-500 modules, the CPU provides response times as low as 1 ms, ensuring real-time processing for critical applications.
-
Memory and Data Handling:
- The CENTUM VP CPU modules feature 2 GB DDR4 RAM for rapid data processing and 512 MB flash memory for secure data storage. STARDOM FCN-RTU models include 128 MB SDRAM and up to 256 MB flash memory to handle high-speed data logging and control operations, suited for remote monitoring and logging applications.
-
Redundancy Support:
- Many CPU modules, including those in the CENTUM VP series, support dual-redundant configurations for CPU, power supply, and control network connections, providing automatic failover capabilities. This redundancy increases system reliability and ensures continuous operation, meeting the requirements of high-availability environments.
-
Scalability:
- Yokogawa’s CPU modules support modular expansions, allowing the addition of up to 64 I/O modules in the CENTUM VP system and up to 8 expansion racks in STARDOM FCN-500. This scalability enables easy system growth to meet increasing process demands without extensive reconfiguration.
-
Robust Communication Capabilities:
- Yokogawa CPU modules are compatible with a variety of communication protocols. The CENTUM VP CPUs include up to 2 Ethernet ports with 1 Gbps speed, supporting protocols like Modbus TCP/IP, OPC UA, and EtherNet/IP. STARDOM FCN modules support Modbus RTU, HART, and DNP3, making them ideal for remote and distributed applications.
- FCN-500 modules offer up to four network interfaces, allowing flexible integration across industrial Ethernet and field network setups.
-
Operating Conditions:
- Designed for industrial resilience, the STARDOM FCN-500 modules operate within a temperature range of -20°C to 70°C and offer high resistance to shock and vibration, meeting IEC 60068-2 standards. This ensures reliable performance in harsh environments.
