EK1100 EtherCAT Coupler
The EK1100 coupler connects the EtherCAT Device Protocol with the EtherCAT Terminals (ELxxxx/ESxxxx/
EMxxxx). One station consists of a coupler, any number of EtherCAT Terminals and a bus end terminal, e.g.
EL9011.
The coupler converts the telegrams from Ethernet 100BASE-TX to E-bus signal representation in passing
with minimum latency The coupler is connected to the network via the upper Ethernet interface. The lower
RJ-45 socket may be used to connect further EtherCAT devices in the same strand.
The coupler supplies the connected terminals with the necessary E-bus current for communication. The
coupler can supply a maximum of 5V/2A. Power feed terminals (e.g. EL9410) must be integrated if more
current is required.
In the EtherCAT network, the EK1100 coupler can be installed anywhere in the Ethernet signal transfer
section (100BASE-TX). The coupler thereby processes exclusively unaddressed MAC Broadcast telegrams
of the type EtherCAT Device Protocol from the EtherCAT master. Since directed addressing via MAC
Unicast or IP addressing is not used, neither a switch nor a router can be used.
