CC-Link IE Field Network Remote Head Module

The CC-Link IE Field head module can control the I/O and intelligent function modules directly when installed on the same base unit, and can operate as a network remote station. Installing two remote head modules improves network reliability by having redundant network lines, and supports online module replacement (hot-swap) when a module needs to be changed while the system is still in operation.

Distributed control or redundant system can be easily realized

Wiring and space saving distributed control system
Realize a highly scalable distributed control system by combining with various I/O and intelligent function modules.

Remote station with redundant head modules and network
Network system reliability can be improved by installing redundant head modules and redundant network cables; even if an error occurs in one of the head modules, the network standby module can take over without disrupting network communications and initiates the control system to switch to the standby system. In addition, if one of the head modules is replaced, the settings and parameters are automatically transferred to the standby module and re-initialized.
