Invalid configuration states of the ET 200SP on PROFINET IO

Invalid configuration states
The following invalid configuration states of the ET 200SP distributed I/O system lead to the
failure of the IO device or prevent data exchange:
● Number of modules exceeds maximum configuration.
● Faulty backplane bus (e.g. defective BaseUnit). ET 200SP backplane bus interruptions do
not trigger an interrupt.
● At least one I/O module is plugged into a different BaseUnit as the one configured in the
parameters.
● No server module.
● Invalid or incorrectly configured BusAdapter.
Note
Removal of the server module will trigger a station stop. All I/O modules of the ET 200SP
distributed I/O system fail (substitute value behavior) but the interface module continues to
exchange data.
Revoking the station stop (by correcting the invalid configuration state) leads to a brief failure
of the ET 200SP distributed I/O system and automatic restart.
