CC-Link IE Field Network master/local module
Flexible wiring topologies according to the layout of production lines, equipment, and devices are supported.
In addition, setup and troubleshooting are easy.
Easy setup and troubleshooting
- Easy setup
- Easy troubleshooting
- Just setting link device points and assignment to the master station, the setting can be automatically transferred to each local station, thereby allowing easy network setup
- Easy troubleshooting without relying on experience and knowledge is possible on the engineering software GX Works3
Multiple topology variations
- Flexible network
- Star topology
Devices are connected via an Ethernet switch allowing device stations to be added easily. - Line topology
Continuous connection of devices along the Ethernet line, reducing wiring cost. - Ring topology
Connection is done in a continuous loop, which guarantees communications by isolating the faulty network station.

CC-Link IE Field Network remote head module
The remote head module installed in the CPU slot can control modules on the base unit via network.
Highly reliable distributed control and redundant system
- Reduced wiring
- Highly reliable
- Wiring and space saving distributed control system can be achieved
- Installing redundant head modules and redundant network cables ensure continuous communication; even if an error occurs in one of the head modules, the network standby module can take over without disrupting network communications and initiate the control system to switch to the standby system
The module within the red box is CC-Link IE Field Network remote head module (RJ72GF15-T2).
