5 Detailed descriptions of the eldbus coupler
5.1 PROFIBUS eldbus coupler
UR20-FBC-PB-DP
The UR20-FBC-PB-DP eldbus 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 accessed with a system-independent
web server application via the USB service interface. Thus,
all information, such as diagnostics, status values and para-
meters, can be read and all connected modules can be simu-
lated 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.

Collective error Red: Conguration error, or error in the coupler,

message
Red ashing: Station in Force mode
BF
Bus failure Red: No connection to the eldbus

to the control unit, or error in the parameter set or
slave address error or rmware update is running

Addressing
The eldbus 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!
