Compilation error after deleting a machine module in the ApplicationTemplate (eliminated from V3.5.1)

Eliminated from:
PLC Designer V3.5.1 (Service Pack 1)

Behaviour of the new version?
When a machine module is deleted, the persistent data area is rearranged automatically. Therefore, no error message will occur after deleting a machine module.

Due to the modified persistent data area, carry out a project download instead of an online change.



What happens?
The PLC Designer outputs the following error message when the project is compiled:

C0077: Unknown 'xxx' type

When does the problem occur?
After deleting a machine module, the above error message appears during project compilation.

Which products are affected?
PLC Designer from V3.5.0

Diagnostics options?
None

Short-term measures/recommendations?
Open the MM_PD variables list (folder A55_VarLists) in the Application Template and use the right mouse button to open the context menu. Execute the Rearrange list and clean gaps command.

Evaluation:
Deleting a machine module leads to gaps in the persistent data area. This leads to error messages during project compilation. The above-described recommendation provides a workaround for the function restriction.
