5.3 EtherCATeld-buscouplerUR20-FBC-EC
The UR20-FBC-EC eld-bus coupler is an EtherCAT par-
ticipant certied by the EtherCAT* Technology Group. The
coupler is the head module for the u-remote system bus, to
which up to 64 active u-remote modules can be connected.
The EtherCAT coupler has two Ethernet ports, and the inte-
grated switch supports a line network structure.
The coupler can be activated with a system-independent
web server application via the USB service interface or the
EtherCAT. In addition, all information, such as diagnostics,
status values and parameters, can be exported and all con-
nected modules can be simulated or forced.
The station's main power supply is integrated in the coupler.
Power is supplied via two 4-pole connectors, separated into
the input and output current paths.
