In Unity Pro V11.1 and V12.0, when changing the OS version of a PLC CPU in Unity Pro configuration screen, the task time is lost.
The task time must be re-entered manually.

Example: the initial version of the BM P34 2020 was 02.30 and task time : Periodic, 50 ms. After updating in 02.50, the task time : cyclic, with watch dog 205 ms (default values).

This problem will be corrected in Unity Pro V13.0
