Produkt-Beschreibung
1. High-Speed Processing & Large Memory
- 32-bit high-performance ARM industrial processor, fast control cycle down to 10ms, supports massive complex algorithms
- Built-in large storage: 512MB RAM + 1GB flash ROM, stores control programs, historical trends, alarm logs and configuration parameters
- Independent backup lithium RTC battery: retains clock, parameters and offline data for long-term power-off maintenance
- Handles up to 256 mixed analog/digital I/O points, compatible with all CENTUM VP series I/O modules
2. Complete Vnet/IP Dual Ethernet Communication
- Dual integrated RJ45 Ethernet ports for redundant Vnet/IP control bus
- 100Mbps high-speed industrial bus, stable data exchange between CPU, operator stations, HIS and field I/O racks
- Supports cross-system interconnection via Modbus TCP for third-party PLC, analyzers and auxiliary equipment
- Built-in maintenance USB port for local offline program download, parameter backup and firmware upgrade
3. Full Redundancy Support for High Availability
- Hot redundant dual CPU configuration supported (two CP451-50 paired as primary/standby)
- Undisturbed bumpless switchover without process interruption during CPU failure or replacement
- Synchronizes all control logic, real-time data and historical records between master and slave controllers
- Zero production downtime for continuous-process industries (chemical, oil & gas, power)
4. Powerful Built-In Process Control Functions
- Rich native control library: multi-loop PID, cascade PID, ratio control, fuzzy logic, sequence control, batch control
- Integrated alarming system: high/low limit, deviation, rate-of-change, equipment fault alarms with timestamp recording
- Real-time trending, totalization, mass/energy calculation and unit conversion
- Supports SIS interlock logic when matched with ProSafe-RS safety system, compliant with IEC 61508 SIL2/SIL3
5. Comprehensive Self-Diagnosis & Online Maintainability
- Full-module self-diagnosis: CPU core, memory, communication bus, power supply, battery and I/O channel health monitoring
- Real-time fault code display and historical failure log storage for rapid troubleshooting
- Hot-swap capable: replace module online without shutting down the entire control station
- Automatic fault isolation; abnormal CPU will not affect normal operation of other rack modules
6. Open System Interfaces & Software Compatibility
- Fully compatible with Yokogawa integrated engineering tool (CAMS): graphic configuration, offline simulation, online debugging
- Supports standard industrial open interfaces: OPC UA/DA, ODBC, DDE for data interaction with MES, database and upper management systems
- Bidirectional communication gateway function to connect legacy CENTUM CS3000 systems, protecting existing investment
- Remote maintenance: remote firmware update, remote diagnosis and parameter modification via Vnet/IP
7. Robust Industrial Environmental Adaptability
- Standard IP20 protection for indoor control cabinet installation
- Wide operating temperature: -20°C ~ +55°C; storage temperature: -40°C ~ +70°C
- Humidity tolerance: 5%–95% RH non-condensing
- Strict EMC anti-interference design, complies with CE, CSA industrial electromagnetic standards, resists surge, pulse and RF interference
- Low power consumption, no forced cooling fan required, long service life
8. Stable Power Supply & Compact Modular Design
- Rated power input: 24VDC industrial control power, low ripple circuit design
- Standard vertical rack mounting structure, slim single-slot size, saves cabinet space
- Lightweight aluminum alloy housing with good heat dissipation
- Standard suffix definition: CP451-50 = Standard type, non-explosion-proof basic version
