5.2 PROFINET eldbus coupler UR20-FBC-PN-IRT
The UR20-FBC-PN-IRT eldbus coupler is a PROFINET I/O
participant certied by the PROFINET user organisation. 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 PROFINET coupler has two Ethernet ports, and the inte-
grated 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
Ethernet. 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.
