Destination and use
english
The SD-I-DP-V0-2 PROFIBUS gateway is used in conjunction
with non-contact safety sensors and solenoid interlocks with
serial diagnostics. In these components, the diagnostic output is
replaced with a serial input and output cable. If components with
serial diagnostics are wired in series, the inputs and outputs of the
diagnostic channels as well as the safety circuits are wired in series.
In this way, a series-wired chain of maximum 31 either identical
either different components can be set up.
For the evaluation, the serial diagnostic cable is connected to the
here-described PROFIBUS gateway. The Diagnostic gateway con-
verts the serial signals of the series wiring into the PROFIBUS DP-V0
protocol. The gateway is integrated as slave at the end of an exist-
ing PROFIBUS DP system. In this way, the diagnostic signals can
be evaluated in a PLC, which is also integrated in the PROFIBUS
network.
Operational conditions can be read and control commands e.g. to
unlock a solenoid interlock, which is installed on the components of
the series-wired chain, can be transmitted.
The status or failure information of each individual component of
the series-wired chain is automatically loaded in the PLC.
For more information, refer to the detailled manual.
Notes
The PROFIBUS gateway does not realize safety tasks. The safety
monitoring of the above-mentioned safety switching appliances
must be realized independently.
Montage
The PROFIBUS gateway SD-I-DP-V0-2 is designed as IP 10 device
for control cabinet mounting and can be snapped onto standard rails.
Wiring
Terminals:
SD
24 V
0 V
24 VDC supply, approx. 180 mA operating current, PELV supply unit.
Note
The PROFIBUS gateway and all SD slaves must be connected to
the same 24 VDC power supply.
The SD Interface is wired with normal control cables.
The cable for the SD Interface, which is connected to the
PROFIBUS gateway, is maximum 200 m long; its wiring capacitance
is limited to 60 nF. Normal 200-m long control cables of the LiYY or
H05 VV-F type with cable sections of 0.5 mm
wiring capacitance of approx. 30 – 45 nF.
The PROFIBUS must be connected by means of default PROFIBUS
cables and a default PROFIBUS connector with integrated terminal
resistor.

Addressing of the PROFIBUS gateway
By means of the switches 1-7, the PROFIBUS slave address is
represented binary in accordance with the diagram below. The
address is loaded upon the initialization of the PROFIBUS system
after the start-up.
