The Mitsubishi CC-Link IE Field Network Head Module LJ72GF15-T2-CM serves as an intelligent device station with 1 Gbps transmission speed. It supports 2048 remote I/O points and 1024 remote register words. Featuring RAS functionality and an included end cover, it functions as a remote station on the CC-Link IE Field Network, allowing flexible configuration of L-series I/O and intelligent function modules. This reduces wiring and saves space. The RAS function centrally manages error information: when an error occurs at the remote station, the error log is saved to the head module's latch area and instantly notified to the master station. Even after a power cut, the logged errors are retained, aiding quick fault identification and minimizing downtime.
