UR20-FBC-PB-DP
The UR20-FBC-PB-DP eld-bus coupler is a PROFIBUS-DP
participant certied by the PROFIBUS 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 PROFIBUS-DP coupler has a Sub-D socket and supports
all services in accordance with the DP-V1 specication.
The coupler can be activated with a system-independent
web server application via the USB service interface. In addi-
tion, all information, such as diagnostics, status values and
parameters, can be exported and all connected 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.

Addressing
The eld-bus coupler on the PROFIBUS-DP is addressed via
the two rotary switches.
A maximum of 125 addresses (1 to 125) can
be assigned. Each address may be assigned
only once in the overall bus structure.
Addresses 1 and 2 are generally used by the
control systems. Bus addresses 000 plus 126
and higher may not be used!
