These connectors are provided for the fiber optic connectors between your
PROFIBUS coupler and PROFIBUS.
The diagram on the left shows the layout of the interface.
Every PROFIBUS slave has an internal power supply. This power supply
requires DC 24V. In addition to the electronics on the bus coupler, the
supply voltage is also used to power any modules connected to the
backplane bus. The "max. current drain at backplane bus" can be found in
the Technical Data.
The power supply is protected against reverse polarity.
PROFIBUS and backplane bus are isolated from each other.
Attention!
Please ensure that the polarity is correct when connecting the power
supply!
The PROFIBUS slave modules carry a number of LEDs that are available
for diagnostic purposes on the bus and for displaying the local status. The
following table explains the different colors of the diagnostic LEDs.
Label
Color
Description
PW
green
Indicates that the supply voltage is available on the backplane bus (Power).
ER
red
Turned on and off again when a restart occurs and is permanently on when an
internal error has occurred.
Blinks when an initialization error has occurred.
Alternates with RD when the master configuration is bad (configuration error).
Blinks in time with RD when the configuration is bad.
RD
green
Is turned on when the status is "Data exchange" and the V-bus cycle is faster
than the PROFIBUS cycle.
Is turned off when the status is "Data exchange" and the V-bus cycle is slower
than the PROFIBUS cycle.
Blinks when self-test is positive (READY) and the initialization has been
completed successfully.
Alternates with ER when the configuration received from the master is bad
(configuration error).
Blinks in time with ER when the configuration is bad
DE
green
DE (Data exchange) indicates PROFIBUS communication activity.
This address selector is used to configure the PROFIBUS address for the
DP slave. Addresses may range from 1 to 99. Addresses must be unique
on the bus.
0 1
The slave address must have been selected before the bus coupler is
turned on.
When the address is set to 00 during operation, a once-off image of the
diagnostic data is saved to Flash-ROM. Please take care to reset the
correct PROFIBUS address, so at the next PowerOn the right PROFIBUS
address is used!
