Network module

The network module lineup fulfills new needs for industrial networks: system-wide optimization including high-speed control, large capacity data management, flexible wiring, and easier setup/maintenance required in manufacturing.

Open integrated networking across the manufacturing enterprise

  • Integrates IT system information communications and real time control communications on the same network
  • Highly accurate time synchronization within ±1 µs is possible between connected stations, allowing precise time-series analysis when an error occurs
  • High-precision motion control with minimum communication cycle time of just 31.25 µs*1

High-speed, large-capacity, and highly-reliable distributed control network for controllers

  • Realizes 128K word (maximum link points) large data bandwidth and 1 Gbps high-speed communication
  • Multi-functions such as dual-loop optical network and external power supply enable highly-reliable distributed control system

Field network realizing highly-flexible wiring

  • Enables safety control and motion control as well as communications between multiple controllers and I/O control
  • Realizes flexible wiring topologies according to the layout of production lines, equipment, and devices
