Incorrect module configurations of ET 200S on the PROFINET IO

Incorrect module configuration
The following incorrect configuration states of the ET 200S result in a failure of the ET 200S
IO device or prevent data exchange.
● Starting with 2 missing modules
● Terminating module missing
● Number of modules exceeds maximum configuration
● Rear panel bus fault (for example, defective terminal module)
Note
The IO device will not start up if one or more modules are missing (gap) and the ET 200S
is switched on.

Interruption of the ET 200S backplane bus

Separate diagnostics of bus interruption
If the ET 200S does not start up, the causes can be as follows:
● 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.
You can read this information with STEP 7 in the SIMATIC Manager via "Accessible
participants" in the "Module status" window. To this end, the PD must be available in the
PROFINET sub-net. The information is displayed in text format.
