TM5NS31 | Schneider Sercos III Communication Module Supplier

Introduction to the TM5NS31

As industrial automation evolves, the demand for high-speed, deterministic communication grows. The TM5NS31 from Schneider Electric meets this need as a dedicated Sercos III communication module within the Modicon TM5 range. Designed for seamless integration with Modicon LMC078 motion controllers, it provides robust field bus interface capabilities for demanding motion control applications.

Key Features and Technical Specs

• Physical interface: RJ45 connectors for Sercos III and Ethernet/IP.
• Integrated connection type: Ethernet/IP with 2 RJ45 connectors at 100 Mbit/s.
• Current consumption: 5 V DC base.
• Power dissipation: 1.75 W.
• Product weight: 0.03 kg.
• Local signalling: 1 LED green/red for STAT, 1 LED green/red for Sercos III, and 2 LEDs green for Sercos III ports 1 and 2.
• Resistance to electrostatic discharge: 4 kV contact and 8 kV air per EN/IEC 61000-4-2.
• Resistance to electromagnetic fields: 10 V/m from 80 MHz to 2 GHz per EN/IEC 61000-4-3.
• Surge withstand: 0.5 kV differential mode and 1 kV common mode per EN/IEC 61000-4-5.

A standout feature is the dual-protocol support: the TM5NS31 integrates both Sercos III and Ethernet/IP, enabling flexible network topologies and simplified system architecture.

Applications and Use Cases

In high-precision motion control systems, the TM5NS31 excels at synchronizing multiple axes over a Sercos III ring. For instance, in packaging machinery, it coordinates servo drives with minimal jitter, improving throughput. Additionally, its Ethernet/IP connectivity allows straightforward integration with upstream PLCs and HMIs, reducing engineering effort.

Installation and Setup

Mount the TM5NS31 onto a Modicon TM5 bus base (ordered separately) and connect the required power supply and terminal block. Use standard RJ45 cables for Sercos III and Ethernet/IP links. Ensure proper grounding and follow Schneider’s wiring guidelines to maintain signal integrity. The module’s compact 0.03 kg weight simplifies DIN rail installation.

Maintenance and Reliability

Routine inspection of LED indicators helps verify communication status. The module’s robust EMC immunity reduces the risk of data corruption in noisy industrial environments. Periodic cleaning of connectors and verification of cable integrity extend service life. For critical systems, schedule annual checks per the manufacturer’s manual.

Compatibility and Integration

The TM5NS31 is designed for Modicon LMC078 motion controllers and supports Sercos III at 100 Mbit/s. It also features Ethernet/IP via two RJ45 ports, enabling integration with standard industrial networks. This dual-interface capability allows the module to serve as a bridge between motion control and plant-wide automation systems.
