EK1122-0000
The 2-port EtherCAT junction enables configuration of EtherCAT star topologies. A modular EtherCAT star
hub can be realized by using several EK1122 units in a station. Individual devices or complete EtherCAT
strands can be connected at the junction ports. The EtherCAT junctions are connected via RJ-45 sockets
with direct display of link and activity status. The Run LED indicates the status of the EK1122. Through
TwinCAT and other suitable EtherCAT masters the EK1122 also supports coupling and uncoupling of
EtherCAT strands during operation (hot connect).
EK1122-0080
Hot Connect is an EtherCAT feature for changing topologies through direct coupling or uncoupling during
operation. Coupled EtherCAT components are already quickly linked to the data communication after
connection as standard. Fast hot-connect technology further reduces the connection time significantly,
enabling even faster tool changes. Fast hot-connect ports may only be connected to each other, which is
why they are specially identified.
The EK1122-0080 EtherCAT junction with Fast Hot Connect is complemented by the EK1101-0080
EtherCAT coupler with Fast Hot Connect.
