Result Of The Preset/Actual Comparison In Modules That Cannot Be; Parameterized; Result Of The Preset/Actual Comparison In The Case Of Parameterizable - Siemens SIMATIC ET 200S Manual

What happens when modules are inserted during operation
If you reinsert a module that has been removed in the ET 200S I/O system during
operation, the CPU carries out a preset/actual comparison for the inserted module.
This compares the configured module with the one that is actually inserted. The
following activities occur depending on the result of the preset/actual comparison:
Modules that cannot be parameterized
The following activities occur irrespective of whether the power module of the
inserted module is switched on or off.

OB 83 is called with the corresponding
diagnostic buffer entry (event ID 3861
The module is entered in the system status
list as available.
Direct access is again possible.
Modules that can be parameterized
The following activities only occur when the power module of the inserted module
is switched on.

The CPU reparameterizes the module.
If parameter assignment is successful, the
module is entered in the system status list
as available.
Direct access is again possible.
