IMPORTANT
Distributed I/O module assignments made while in the test mode are saved
in Flash memory.
After loading an application designed to use Distributed I/O modules, these
assignments are used to automatically update the assignments in the
application, but only if module address and module type match. This
update can be inhibited by restarting the controller with the square reset
switch on the CPU module – the assignments done in the test mode are
deactivated and not used to update the assignments in the application.
To reactivate such deactivated assignments, use the option 'Use existent
Assignment' in the 'Distributed I/O Module Assignment' screen as shown
above. Then the assignment update is done in the loaded application.
Each time the assignments for a loaded application are changed by the
user, the application should be saved to Flash memory to save these
changes and to guarantee their availability after any controller restart. This
also applies to the test mode during startup.
