Diagnostics via diagnostic address with STEP 7

Malfunctions that occur in the ET 200S are indicated by the "SF" LED, and the
cause is entered in the diagnostic buffer of the IM 151-7 CPU. Either the CPU
enters STOP mode, or you can respond to errors by means of error or interrupt
OBs in the user program.
To enable a response to be made, it must be possible to identify whatever caused
the problem by means of a diagnostic address.
Diagnostic addresses
If you run the ET 200S with a DP master from the SIMATIC S7 range on the
PROFIBUS-DP, diagnostic addresses are assigned in STEP 7 as follows:
You specify two diagnostic addresses during configuration:
DP master (SIMATIC S7)
Diagnostic address
When configuring the DP master, you specify
(in the associated project for the DP master)
a diagnostic address for the ET 200S.
The DP master receives information on the
status of the ET 200S or on a bus
interruption by means of this diagnostic
address.

Diagnostic address
During configuration of the ET 200S, STEP 7
sets the diagnostic address for slot 2 to 2045
by default for the ET 200S (in the associated
project for the ET 200S).
The ET 200S receives information on the status of
the DP master by means of this diagnostic
address.
