6.8 Diagnostics with STEP 7
Update interrupt
The update interrupt is reported when the following requirements are met:
● The parameters were incorrectly assigned.
● The parameter assignment of the ET 200iSP deviates from the parameters and
identification data that is stored retentively in the modules.

Diagnostics for incorrect ET 200iSP configuration statuses

Incorrect configuration states
The following incorrect configuration statuses on the ET 200iSP lead to an ET 200iSP station
failure or prevent startup of the data exchange. These reactions are not dependent on the
setting of the IM 152 parameter "Operation at Preset <> Actual Configuration":
● Two missing electronic modules
● Terminating module missing
● Number of modules exceeds the maximum configuration
● Backplane bus fault (for example defective terminal module)
Note
If one module is missing (gap) and the ET 200iSP is powered down and powered up again,
the ET 200iSP will not start up. Startup with more than one missing module is not possible.
If more than one electronic module is missing, then the ET 200iSP can only be guaranteed
to start up reliably after these modules are inserted if the power is switched OFF and ON
again.
