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

*1. This value is achieved when fast operation mode of the motion module (RD78GH) is used. For details, please refer to the MELSEC iQ-R Motion Module User's Manual (Application) (IB-0300411ENG) .

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

Network features

Networks best for each application can be selected. ^*2
