Schneider 490NRP25400 is an advanced industrial network redundancy module designed to enhance the reliability of Ethernet-based communication in Modicon M340/M580 PLC systems. As an upgraded version in the 490NRP series, it builds on the capabilities of the 490NRP25300 with improved redundancy protocols and expanded compatibility, making it ideal for mission-critical industrial automation environments where uninterrupted network connectivity is paramount. Below is its detailed specification:
- Manufacturer: Schneider Electric
- Product Series: Modicon M340/M580 (mid-to-high range PLC platforms)
- Model: 490NRP25400
- Product Type: Advanced Ethernet network redundancy module
- Compatibility:
- Primary compatibility: Modicon M340 (e.g., BMXCPU31100) and M580 (e.g., BMXCPU51200) series PLCs.
- Supports integration with EcoStruxure Automation Expert and Machine Expert software.
- Works with industrial Ethernet switches (managed/unmanaged) and third-party devices using Modbus TCP/Ethernet/IP.
- Physical Attributes:
- Weight: Approximately 0.13 kg
- Form Factor: Compact modular design, fits 1 slot in Modicon M340/M580 racks
- Protection Class: IP20 (requires installation in a control cabinet with IP20+ protection)
Enhanced Redundancy Protocols:
Supports both
EcoStruxure Machine Expert Redundancy (ring topology) and
Parallel Redundancy Protocol (PRP) as defined in IEC 62439-3. PRP enables simultaneous data transmission over two independent networks, ensuring zero switchover time (< 5 ms) in case of a network failure—superior to traditional ring redundancy for ultra-critical applications.
Dual Gigabit Ethernet Ports:
Equipped with 2 x 10/100/1000 Mbps Gigabit Ethernet ports (RJ45), supporting auto-negotiation and full-duplex communication. This higher bandwidth (up to 1 Gbps) accommodates large-volume data transmission, such as high-frequency process variables or video streams from machine vision systems.
Advanced Network Monitoring:
Integrates real-time diagnostics for network health, including link status, packet loss, and latency measurements. Faults are logged with time stamps and can be accessed via PLC registers or EcoStruxure software, enabling predictive maintenance and rapid troubleshooting.
Seamless Protocol Integration:
Natively supports Modbus TCP, Ethernet/IP, and PROFINET (via protocol translation), facilitating interoperability with multi-vendor systems (e.g., Siemens, Rockwell) in heterogeneous industrial networks.
Cyber-Security Features:
Includes basic security mechanisms such as port isolation, MAC address filtering, and support for IEEE 802.1X authentication, reducing the risk of unauthorized network access in critical infrastructure.
- Safety Standards: CE, UL 508, CSA C22.2 No.14
- EMC Compliance: IEC 61000-6-2 (immunity), IEC 61000-6-4 (emissions)
- Network Standards: IEEE 802.3 (Ethernet), IEC 62439-3 (PRP)
- Hazardous Areas: ATEX Zone 2 certification (for use in potentially explosive environments)
- Configuration Tool: EcoStruxure Machine Expert (V2.5+) or Automation Expert
- Key Settings: Redundancy mode (PRP/ring), network parameters, security policies, and diagnostic thresholds
- Remote Management: Supports SNMPv3 for remote monitoring and configuration via network management systems
- Critical Process Control: Oil refineries (ESD systems), chemical plants (reactor communication loops)
- High-Speed Manufacturing: Automotive production lines (real-time robot coordination)
- Energy Infrastructure: Power grids (substation automation), renewable energy plants (SCADA connectivity)
- Transportation: Railway signaling systems, airport baggage handling networks
For optimal performance, pair with Schneider’s managed switches (e.g., BMXNOE01100) and ensure firmware compatibility with PLC CPUs. Refer to Schneider’s official datasheet for detailed wiring diagrams and redundancy setup guides.
