An EtherCAT junction allows you to wire network devices into separated sections or branch lines, which prevents a single device failure from crashing the entire network.
Benefits of Separated EtherCAT Junctions
Isolated Failures: If a cable disconnects or a slave device fails in one branch, only that specific separated section stops working; the rest of the network keeps communicating with the master controller.
Easier Debugging: Maintenance staff can troubleshoot one isolated section or machine module without shutting down or diagnosing the whole system.
Flexible Topologies: Junctions enable tree, star, and drop-line branch configurations instead of a strict single daisy-chain path.
Hot Connect Support: You can plug or unplug specific machine segments and junction branches while the network remains fully powered and run
The ECAT-0105S EtherCAT junction can be used in an EtherCAT Terminal segment at any desired position between the EtherCAT Terminals and enables configuration of EtherCAT star topologies.
A modular EtherCAT star hub can be realized by using several ECAT-0105S Module in a station.
