5.3 EtherCAT eldbus coupler UR20-FBC-EC
The UR20-FBC-EC eldbus coupler is an EtherCAT partici-
pant certied by the EtherCAT
1)
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, the integrated
switch supports a line network structure.
The coupler can be accessed with a system-independent
web server application via the USB service interface or the
EtherCAT. Thus, all information, such as diagnostics, status
values and parameters, can be read and all connected mod-
ules 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.
