The Schneider Electric TM5NS31 SERCOS III communication module serves as a critical component within the Modicon TM5 I/O system. Its primary function is to act as a bus coupler, effectively creating distributed I/O islands on a SERCOS III fieldbus network. This particular setup enables seamless data exchange between a central motion controller and remote I/O modules. Consequently, it proves especially suitable for high-performance machinery and coordinated motion applications.
Additionally, the TM5NS31 module works specifically with the Modicon LMC078 motion controller and other PacDrive 3 systems. It guarantees deterministic communication, which is absolutely vital for precision motion control tasks. Furthermore, its compact physical design and rugged build quality make it a reliable choice for demanding industrial environments.
This section outlines the core technical attributes of the TM5NS31 module in detail.
First, regarding communication capabilities, the module fully supports the SERCOS III fieldbus protocol. Moreover, it also includes integrated Ethernet/IP connectivity for additional networking flexibility. Second, for physical interfacing, it comes equipped with two parallel RJ45 connectors dedicated to the SERCOS III network. These ports support a standard data rate of 100 Mbit/s, ensuring fast and reliable data transmission.
Next, concerning power requirements, the module draws a current of 350 mA at 5 V DC from its bus base. Its maximum power dissipation is rated at a low 1.75 W, which helps maintain energy efficiency. Meanwhile, regarding compatibility, the TM5NS31 is engineered for seamless operation with the Modicon LMC078 motion controller. However, please be aware that the module itself requires additional components for full operation. For instance, you must order a bus base, a power supply, and a terminal block separately, as these are not included with the module.
Furthermore, for status monitoring, the module incorporates several on-board LEDs. Specifically, it features a green/red LED for STAT, another green/red LED for SERCOS III activity, and two dedicated green LEDs for each of the SERCOS III ports. Therefore, operators can easily diagnose network and module status at a glance.
The TM5NS31 is specifically engineered to withstand harsh industrial conditions. For example, its physical dimensions are compact, measuring just 37.5 mm in width, 99 mm in height, and 75 mm in depth. Additionally, the module itself weighs only 0.03 kg, making it extremely lightweight and easy to handle during installation.
Moreover, this module meets rigorous environmental resilience standards. For instance, it offers resistance to electrostatic discharge up to 4 kV on contact and 8 kV in air, conforming to EN/IEC 61000-4-2. Meanwhile, it withstands electromagnetic fields up to 10 V/m (80 MHz...2 GHz) and 1 V/m (2...2.7 GHz), as specified in EN/IEC 61000-4-3. Besides these, the TM5NS31 also provides surge withstand capabilities of 0.5 kV differential mode and 1 kV common mode, per EN/IEC 61000-4-5. As a result, this module delivers reliable performance even in electrically noisy environments. Finally, it is a Green Premium compliant product, reflecting Schneider Electric's commitment to environmental sustainability.
Properly installing the TM5NS31 is a straightforward process, thanks to the Modicon TM5 system's modular architecture. First, begin by mounting the required bus bases onto a standard 35 mm DIN rail. Next, take the TM5NS31 electronic module and insert it into its dedicated bus base. Press down firmly until you hear a distinct click, confirming it is securely seated. Then, mount the terminal block onto the assembly to complete the hardware setup.
After completing the mechanical assembly, proceed with the wiring. Connect the SERCOS III network cables to the two RJ45 ports on the module's front face. Typically, the bus topology used is a line configuration. For example, connect the first port to your SERCOS master device, such as the LMC078 controller. Then, connect the second port to the next SERCOS slave device further down the line. Meanwhile, do not forget to set the SERCOS III node address using the rotary switches located on the front panel.
Finally, once hardware setup and addressing are complete, proceed to configuration. The bus coupler automatically detects all connected TM5 I/O modules. Consequently, it builds a local process image without requiring manual mapping. Therefore, this automated discovery significantly simplifies and accelerates the overall startup process.
