Startup of the ET 200S
Switch on the supply voltage
for the DP slave.
DP slave receives configuration
data from the DP master.
DP slave sets outputs to ”0”
and accepts the set
PROFIBUS address.
”BF” LED off;
inputs and outputs
are enabled;
data transfer possible.
Yes
No
Does the configuration
data correspond to the
actual setup?
Remedy: Alignment of online
and offline configuration data
The ”ON” LED comes on
and the ”BF” LED flashes.
”Startup when expected < > actual
configuration” parameter disabled (only
in the case of DPV 0)

Note
All interface modules support the default startup. In other words, you do not have
to carry out configuration using the DDB file or HWCONFIG.
In this case the following conditions apply:
• The default parameters are used (see the parameters for the electronic
modules).
• AKF (general identifier format in compliance with the PROFIBUS standard) in
the configuration frame
• Grouping (packing) of the electronic modules is not possible without
parameterization.
• All supply voltages must be switched on at the power modules.
• It is not possible to remove or insert modules during operation.
