Invalid Configuration States Of The Et 200Sp On Profinet Io; Failure Of Supply Voltage L+ At Baseunit Bu - Siemens SIMATIC ET 200SP Manual

5.3.2

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 the exchange of user data with the I/O modules.
● Number of modules exceeds maximum configuration
● Faulty backplane bus (e.g. defective BaseUnit). ET 200SP backplane bus interruptions do
not trigger an interrupt.
● Missing server module
● At least one I/O module is installed in a different BaseUnit than the one configured in the
parameters.
Note
If you remove more than one I/O module or the server module, this results in a station stop.
All I/O modules of the ET 200SP distributed I/O system fail (substitute value behavior) but
the interface module is still exchanging 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.

5.3.3 Failure of supply voltage L+ at BaseUnit BU...D
Failure of the supply voltage L+
The I/O modules react as follows to failure of the supply voltage L+ on the BaseUnit BU...D:
● If an I/O module is removed during failure of the supply voltage, a pull interrupt is
generated.
● If an I/O module is installed during failure of the supply voltage, a plug interrupt is
generated.
