Controllers MELSEC iQ-R Series Product features -Network-
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
