Detailed Information on Schneider 140CPU67160S

1. Basic Information

• Manufacturer: Schneider Electric
• Product Series: Modicon Quantum (industrial-grade large-scale PLC platform)
• Model: 140CPU67160S
• Product Type: Enhanced hot-standby safety CPU module (S suffix indicates safety-focused enhancements)
• Compatibility: Fully compatible with Modicon Quantum series racks, power modules (e.g., 140CPS12400), I/O modules, and communication modules. Seamlessly integrates with hot-standby redundancy setups (requires 140CR series redundancy modules).
• Physical Attributes: Weight approximately 0.5 kg; modular design fitting standard Modicon Quantum rack slots for easy installation and replacement.

2. Core Performance Parameters

3. Safety & Certification

• Safety Ratings: Certified to SIL 3 (per IEC 61508/61511) by TÜV Rheinland, suitable for safety-critical applications (e.g., emergency shutdown systems, HIPPS).
• Safety Mechanisms:
  • Hardware fault detection (via built-in self-testing, BIST) with 99.9% diagnostic coverage.
  • Secure memory partitioning to separate safety and non-safety code.
  • Integrity checks for program execution and data transmission (CRC validation).
• Compliance: CE, UL 508, CSA C22.2 No. 14, ATEX (Ex II 2G Ex d IIC T4), IEC 61131-2 (industrial control equipment standards).

4. I/O Expansion Capability

• Local I/O: Disabled in hot-standby mode (focus on distributed/remote I/O for redundancy).
• Distributed I/O:
  • Max digital I/O: 31,744 points (inputs + outputs) via remote networks.
  • Max analog I/O: 1,984 points (inputs + outputs) for process variables (temperature, pressure, flow).
• Network Support: Compatible with Modbus Plus, Ethernet/IP, and Profinet for distributed I/O communication, with up to 63 drops per network.

5. Communication Interfaces & Expansion

• Built-in Ports:
  • 1 x Modbus Plus port (for high-speed peer-to-peer communication and distributed I/O).
  • 1 x Modbus port (RS232/485, configurable for HMI or device communication).
  • 1 x USB port (for local programming, configuration, and data retrieval).
  • 1 x 10/100 Mbps Ethernet TCP/IP port (supports Modbus TCP, hot-standby synchronization, and SCADA integration).
• Expansion Slots: Supports up to 6 optional communication modules (e.g., 140NOE77101 Ethernet, 140NOM21100 Modbus, 140CRP93200 redundancy) to add protocols like Profibus DP or enhance redundancy.

6. Power & Backup

• Rack Bus Current Requirement: 2,500 mA (powered by Modicon Quantum power modules; ensure sufficient capacity for redundant setups).
• Backup Battery:
  • Type: Lithium-ion (Li-ion) for non-volatile data retention.
  • Capacity: 1,200 mAh.
  • Service Life: ~10 years at 25°C (backs up RAM data, RTC, and safety configuration during power loss).

7. Environmental Ratings

• Operating Temperature: 0°C to 60°C (suitable for harsh industrial environments).
• Storage Temperature: -40°C to 85°C (for transportation and idle storage).
• Relative Humidity: 5%–95% RH (non-condensing, resistant to humid conditions in water/wastewater facilities).
• Vibration/Shock Resistance: 5 g vibration (10–150 Hz, IEC 60068-2-6); 30 g shock (11 ms, IEC 60068-2-27).

8. Software & Functional Features

• Programming Software: Compatible with Schneider Unity Pro (V11.0+) and EcoStruxure Control Expert, supporting IEC 61131-3 languages (LD, ST, FBD, SFC, IL) for safety and non-safety code development.
• Key Functions:
  • Safety logic execution (separate from standard control logic) with forced integrity checks.
  • Advanced data logging (stores safety events, diagnostics, and process trends for compliance audits).
  • Online modification of non-safety code (without interrupting safety functions) to minimize downtime.
  • Cyber security features (password protection, secure boot, and encrypted communication).

9. Typical Applications

• Safety-Critical Process Industries: Oil & gas refineries (emergency shutdown systems, ESD), chemical plants (toxic gas monitoring), and pharmaceutical facilities (batch process safety interlocks).
• Energy & Utilities: Power generation (turbine protection systems), water treatment (pump safety shutdown), and nuclear auxiliary systems.
• Heavy Manufacturing: Steel mills (rolling mill safety controls) and pulp/paper (digester pressure safety loops).
