Response of the new version:
After an exception in the PLC application and subsequent switching of the controller to mains, the boot application is not deleted.
What happens?
After switching on the controller, the PLC program is not processed. The boot application is deleted on the SD card.
The boot application is automatically executed after the controller is switched on and contains, among other things, the PLC program.
When does the behaviour occur?
If an exception occurs in the PLC processing and the controller is then switched off, it can happen in rare cases that the boot application is deleted when it is switched on.
Which products are affected?
Cabinet Controller 3200C
Cabinet Controller c520
Cabinet Controller c550
Panel Controller p500
Short-term measures:
Transfer the boot application to the controller again, e.g. by downloading a project with the PLC Designer or restoring a previously performed backup.
Evaluation / recommendations:
In rare cases, an exception error in the PLC processing can lead to the boot application being deleted. The machine can only be started after the boot application has been restored (see Short-term measures).
