Interruption of the ET 200pro backplane bus
Separate diagnostics for bus interruption: USI = W#16#0001
If the ET 200pro does not start up, the causes can include:
● One or several missing modules
● Terminating module missing
● Number of modules exceeds maximum configuration
● Backplane bus fault (for example, defective bus module)
If the data exchange is interrupted, the causes can include:
● At least two modules (compared to a missing module, this is no longer a gap, but rather a
loose backplane bus)
● Terminating module missing
● Backplane bus fault (for example, defective bus module)
ET 200pro backplane bus interruptions do not trigger an interrupt.
You can read this information with STEP 7 in SIMATIC Manager via "Accessible nodes" in
the "Module information" window. This requires that the programming device is available in
the PROFINET subnet. The information is displayed in text format.
