Corrected from:
PLC Designer V3.12
Response of the new version:
The PLC Designer correctly displays the online values of the variables.
What happens:
When working online, no online variable values are displayed in the watch window and in the editor window.
When does this behaviour occur?
The behaviour occurs if a project was downloaded to the controller using PLC Designer V3.8 or lower and if you go online with this project with the controller again after installing PLC Designer V3.9 or higher. In this case, it does not matter if you go online with the PLC Designer which was originally used to download the project or with PLC Designer V3.9 or higher.
Which products are affected?
PLC Designer V3.9 and higher
Short-term measures:
Install the older PLC Designer version on a separate computer on which no PLC Designer ≥ V3.9 has been installed and go online with this PLC Designer.
As an alternative, you can also execute "Clean all" (menu Create>Clean all) in the PLC Designer and download the project once again.
Evaluation/recommendations:
After installing PLC Designer V3.9 or higher, variable monitoring is no longer possible if a project was downloaded with an older PLC Designer version before installing PLC Designer V3.9 or higher.
