The EK1122-0080 supports Fast Hot Connect technology, which

facilitates significantly shorter connection times for EtherCAT 

components with changing topologies. Compared to Hot Connect,

which is an EtherCAT feature and enables direct coupling and uncoupling

of components during system operation, Fast Hot Connect offers even

faster data transfer and allows even faster tool changes.

The EK1122-0080 has two Fast Hot Connect ports, which are implemented

as RJ45 sockets. The Fast Hot Connect ports are specially marked,

since they may only be combined with each other. The EK1122-0080

EtherCAT junction with Fast Hot Connect is complemented by the 

EK1101-0080 EtherCAT coupler with Fast Hot Connect.
