- Compatibility: Fully compatible with all Modicon NW series PLC modules; support connection with Modicon 800/900/984 series PLCs and third-party industrial devices (Modbus TCP/IP compatible); support up to 16 network backplane modules for cascade connection.
- Functional Features:
- 8-slot 32-bit 1 Gbps high-speed backplane bus realizes ultra-low-latency data exchange between installed modules (latency ≤0.1 ms per slot), meeting the high real-time requirements of medium and large-scale industrial control systems for inter-module communication.
- Dual 10/100 Mbps Ethernet ports with Modbus TCP/IP protocol support seamless connection with upper industrial control networks (SCADA, HMI, MES), and auto MDI/MDIX function eliminates the need for crossover cables, simplifying on-site network wiring.
- Backplane bus redundancy and Ethernet port redundancy double insurance design, fault switching time ≤50 ms, ensuring that the PLC system’s internal communication and external network communication are not interrupted due to a single point of failure, and improving the system’s reliability and availability.
- 1 MB independent data buffer for each slot caches the high-speed data transmitted by the module, avoiding data loss and transmission congestion during peak communication periods, and ensuring the integrity and real-time performance of data transmission.
- Hot-swappable slot design allows replacement of faulty modules (CPU, I/O, communication) without shutting down the entire PLC system and backplane bus, effectively reducing the downtime of the production line and improving the maintainability of the system.
- Dual 24 VDC redundant power input ensures the continuous power supply of the backplane bus module, and the independent power protection for each slot prevents the power failure of a single module from affecting the normal operation of other modules and the entire backplane bus.
- Support for up to 16 network backplane modules for cascade connection, expanding the total number of PLC system slots to 128, meeting the ultra-large-scale I/O control and multi-task processing requirements of large industrial automation systems.
- Real-time monitoring of backplane bus operation status, Ethernet network link status, slot module operation status and power supply status via LED indicators and upper software, and accurate fault location for quick troubleshooting.
- Industrial-grade heavy-duty metal shell and rack-mounted design ensure the structural stability and anti-vibration performance of the module, and the wide temperature range and high anti-interference design adapt to the harsh industrial field environment.
- The module can be used as a communication bridge between Modicon NW series PLCs and other Modicon series PLCs (800/900/984), realizing the unified networking and centralized management of multiple PLC systems, and building a large-scale distributed industrial control network.
- Application Scenarios: Widely used in medium and large-scale industrial automation control systems in the fields of petrochemical, metallurgical smelting, power generation, automobile manufacturing and large-scale logistics parks. It is the core communication hub for Modicon NW series PLC systems to build centralized control cabinets in refinery central control rooms, steel mill smelting process control systems, power plant boiler control systems and automobile assembly line main control stations, realizing high-speed data exchange between multiple PLC modules and seamless connection with upper SCADA/MES systems. It is also suitable for large-scale distributed industrial control networks that require cascade connection of multiple network backplane modules, and can be used as a communication bridge for the unified networking of multiple Modicon PLC systems, meeting the ultra-large-scale I/O control and high-reliability communication requirements of large industrial sites.
