Bus voltage failure

Planning and application
The object value of the control value remains unchanged with a download.
During the download, the output behaves just as it would at bus voltage re-
covery. After the download, the switch position remains unchanged and only
changes with the next switch command. Timers will not operate and must be
restarted. Status values of the control values are updated and sent.
Note
After a download with a change, the parameter complies in behaviour
toa reset of the device in the ETS.
If a download of the application is again undertaken (full download) after
a full discharge, the behaviour is the same as after a reset.
After the application is removed or after an interrupted download, manual
operation no longer functions.
After the switch state is set with bus voltage failure, the Electronic Switch
Actuator remains functional until the bus voltage recovers.
