Schneider 490NRP25300 is an industrial-grade network redundancy module specifically designed for Schneider’s Modicon M340/M580 series PLCs (Programmable Logic Controllers). Its core function is to enable redundant network communication, ensuring uninterrupted data transmission between PLCs and upper-level systems (e.g., SCADA, HMI) or between distributed PLCs—critical for high-availability industrial automation scenarios where network downtime could cause production losses or safety risks. Below is its comprehensive specification:
- Manufacturer: Schneider Electric
- Product Series: Modicon M340/M580 (mid-range to high-end PLC platforms for industrial control)
- Model: 490NRP25300
- Product Type: Network Redundancy Module (focuses on Ethernet network redundancy)
- Compatibility:
- Primary compatibility: Modicon M340 and M580 series PLCs (must be used with matching CPU modules, e.g., M340 CPU 140CPU31100, M580 CPU BMXCPU31100).
- Supports integration with Schneider EcoStruxure Automation Expert software and Modbus TCP/Ethernet/IP protocols.
- Works with standard industrial Ethernet switches (e.g., Schneider Unmanaged Switch BMXNOE0100) for redundancy topology.
- Physical Attributes:
- Weight: Approximately 0.12 kg.
- Form Factor: Compact modular design, fitting standard Modicon M340/M580 PLC rack slots (occupies 1 slot).
- Protection Class: IP20 (requires installation in a closed control cabinet with IP20+ protection to resist dust and accidental contact).
- Ethernet Redundancy Support:Enables ring redundancy (EcoStruxure Machine Expert Redundancy protocol) and dual-path redundancy for Ethernet networks. Automatically switches to a backup communication path within < 100 ms if the primary path fails (e.g., cable break, switch failure), ensuring no interruption to data transmission between PLCs and upper-level systems.
- Dual Ethernet Ports:Equipped with 2 independent 10/100 Mbps Ethernet ports (RJ45 interfaces) to connect primary and backup network paths. Supports full-duplex communication, with a maximum data transmission rate of 100 Mbps—meeting the bandwidth needs of real-time industrial data (e.g., process variables, control commands).
- Protocol Compatibility:Natively supports industrial Ethernet protocols such as Modbus TCP and Ethernet/IP, ensuring seamless integration with Schneider’s own automation products (e.g., Magelis HMI) and third-party systems (e.g., Rockwell PLCs) that use these protocols.
- Redundancy Status Monitoring:Integrates LED status indicators (e.g., "Primary Active" green LED, "Backup Active" yellow LED, "Fault" red LED) for visual monitoring of redundancy status. Fault information (e.g., port disconnection, protocol mismatch) is also transmitted to the PLC CPU or EcoStruxure software for remote alerting and fault tracing.
- Industrial-Grade Stability:Built with industrial-grade components, it complies with IEC 61000-6-2 (industrial environment EMC immunity) and IEC 61000-6-4 (EMC emissions) standards. Resists electromagnetic interference (EMI) from on-site equipment (e.g., motors, inverters) and voltage fluctuations, ensuring stable operation in harsh environments (e.g., factories, power plants).
- Safety Certifications: CE (complies with EU Low Voltage Directive 2014/35/EU and EMC Directive 2014/30/EU), UL 508 (US industrial control equipment safety standard), CSA C22.2 No. 14 (Canadian safety standard).
- Industrial Standards: IEC 61131-2 (compatible with PLC hardware design standards), IEEE 802.3 (Ethernet standard compliance for port communication).
- Configuration Software: Requires Schneider EcoStruxure Machine Expert (V2.0 or later) or EcoStruxure Automation Expert. The software provides a dedicated "Redundancy Configuration" interface to set:
- Redundancy topology (ring/dual-path).
- Failover trigger conditions (e.g., port link loss, protocol timeout).
- Status monitoring parameters (e.g., redundancy switch count, fault log retention time).
- Diagnostics: Supports remote access to redundancy status via EcoStruxure software, including real-time display of active paths, fault codes, and historical failover records—simplifying on-site maintenance and troubleshooting.
The 490NRP25300 is widely used in industrial scenarios where network reliability is critical, including:
- Process Industry: Chemical plants (reactor control network redundancy), oil refineries (pipeline monitoring data transmission), and pharmaceutical facilities (batch process communication).
- Manufacturing: Automotive assembly lines (PLC-to-HMI real-time data transmission), electronics factories (SMT machine network redundancy), and food processing lines (production line control signal transmission).
- Energy & Utilities: Power generation plants (turbine auxiliary system communication), water/wastewater treatment plants (pump station network redundancy), and renewable energy (solar/wind farm PLC interconnection).
- For a complete redundancy system, the 490NRP25300 must be used in pairs (one per redundant PLC) and matched with redundant Ethernet switches.
