Controller indicates old firmware version after changing SD card (corrected from V3.9)

Corrected from:
3200C controller V3.9
p500 controller V3.9
 
Response of the new version:
The correct controller version is indicated in parameter 4 (Device: software revision) of the WebConfig.
 
What happens?
Instead of V3.5.1.117, version V3.5.0.92 is displayed in parameter 4 (Device: software revision) of the WebConfig.

When does the problem occur?
If the controller is equipped with firmware version 3.5.1 and an SD card with version 3.5.0 is inserted (e. g. in the case of device replacement), the WebConfig displays version 3.5.0.

Which products are affected?
3200C controller V3.5.1 and higher
p500 controller V3.5.1 and higher

Possible diagnostics:
None

Short-term measures/recommendations:
Instead of inserting the SD card of the old controller into the new controller use the Backup&Restore software to save your project on the old controller and restore it in the new controller.

Evaluation:
After inserting the SD card of a controller equipped with version 3.5.0 into a controller equipped with version 3.5.1, the old version 3.5.0 will still be displayed in the WebConfig of the controller with version 3.5.1. This does not impair the controller functions. The above-described remedy can be used as a workaround for the function restriction.
