Schneider Electric 140CPU67160 module CPU en mode de redondance chaude

Schneider Electric  140CPU67160  module CPU de réserve chaude

Voici une présentation détaillée des caractéristiques fonctionnelles du module CPU de réserve chaude 140CPU67160 de Schneider Electric :

1. Architecture de redondance en mode réserve chaude

Mécanisme de réserve chaude à double machine

• Prend en charge le fonctionnement synchrone en temps réel des CPUs ma?tre et de réserve, échangeant des données via des liens redondants à haute vitesse (par exemple, le réseau Unity).

• En cas de défaillance du CPU ma?tre, le CPU de réserve prend automatiquement le contr?le de manière transparente dans<100ms, ensuring uninterrupted system operation.

Application Scenarios

• Suitable for critical scenarios where downtime is not allowed, such as chemical, power, and rail transit industries.

• E.g., temperature control of reactor vessels in refineries, switch status monitoring in substations.

• 
  

2. High-Performance Computing CapabilityProcessor and Memory

• CPU: PowerPC 603e 266MHz, supporting complex algorithms and multitasking.

• RAM: 1024KB (including 512KB dedicated data storage), expandable to 8MB file storage and 7MB program storage.

Instruction Execution Speed

• Basic logic instructions execute in ~0.05μs, suitable for high-speed closed-loop control (e.g., servo motor positioning).

• 
  

3. Rich Communication InterfacesStandard Ports

• 1× Modbus RS232/485 (supports ASCII/RTU protocols)

• 1× USB 2.0 (for programming and debugging)

• 2× Distributed I/O interfaces (support Unity Network/SyncLink)

Expandable Networks

• Supported via optional modules:

• 6× Ethernet (TCP/IP, Modbus/TCP)

• 6× Profibus DP (master/slave mode)

• 6× Modbus Plus (supports 63 distributed nodes)

Application Value

• Connects PLCs, HMIs, SCADA systems, and third-party devices (e.g., frequency converters, smart meters) to build complex industrial networks.

• 
  

4. Integrated Display and Operation InterfaceLCD Display

• 2-line × 16-character backlit LCD shows:

• CPU status (Run/Stop/Fault)

• Real-time clock and date

• Key I/O point values or alarm messages

Physical Buttons

• 5 programmable buttons (mapped to specific memory addresses) for on-site emergency operations (e.g., shutdown, mode switching).

• 
  

5. Safety Certification and Reliability DesignSafety Rating

• Certified to SIL2 (complies with IEC 61508), supporting safety-related applications (e.g., emergency shutdown systems).

Environmental Adaptability

• Operating temperature: -25°C to +60°C

• Humidity: 5%–95% (non-condensing)

• Vibration resistance: 10–57Hz (1g), 57–200Hz (2g)

Data Protection

• Built-in lithium battery (12mAh) preserves RAM data for up to 10 years during power outages.

• 
  

6. Flexible Programming and DiagnosticsProgramming Languages

• Remote diagnostics via Ethernet or Modbus

• 
  

7. Modular Expansion CapabilityLocal I/O Expansion

• Supports 27-slot local backplanes, configurable with digital/analog I/O modules, communication modules, etc.

Distributed Architecture

• Connects up to 63 remote I/O stations via Unity Network or Profibus DP, with maximum I/O points per station:

• Digital: 8,000 points

• Analog: 1,984 points

Typical Application Scenarios

• Power Systems: Substation automation, generator synchronization control

• Chemical Processes: Reactor temperature/pressure closed-loop control, emergency shutdown systems
