Incorrect Configuration States Of The Et 200S On The Profinet Io - Siemens Simatic ET 200S Operating Instructions Manual

Error types of the further modules
The error types of the power modules, digital electronic modules, analog electronic and the
technological modules are the same as for ET 200S with PROFIBUS DP.
8.2.5.3

Incorrect configuration states of the ET 200S on the PROFINET IO

Incorrect configuration states
The following incorrect structure states of the ET 200S lead to a malfunction of the IO device
ET 200S or prevent the entry in the data exchange:
• Starting with 2 missing modules
• Terminating module missing
• Number of modules exceeds the maximum configuration
• Faulty backplane bus (e. g. terminal module is defective)
8.2.5.4 Interruption of the ET 200S backplane bus
Separate diagnostics of bus interruption
If the ET 200S does not start up, this may have the following causes:
• One or several missing modules
• Terminating module missing
• Number of modules exceeds maximum configuration
• Backplane bus fault (for example, defective terminal module)
If the data exchange is interrupted, it may have the following causes:
• At least two modules (compared to a missing module, this is no longer a gap, but rather a
• Terminating module missing
• Backplane bus fault (for example, defective terminal module)
ET 200S backplane bus interruptions do not trigger an interrupt. The information must be
read out explicitly by the user. The data record, index F00B
information. You can read this data record with STEP 7 in the SIMATIC manager via
available participant in the module status window. To this end, the PD must be available in
the PROFINET sub-net.

Note
If one module is missing (gap) and the ET 200S is switched on POWER ON, the IO
device will not start up.
