Corrected from:
PLC Designer Installer V4.1.1
Behavior of the new version:
Add-ons for older PLC Designer versions can no longer be updated. In the PLC Designer Installer, these PLC Designer versions are marked as 'Locked'. The <Change> button is grayed out.
To install add-ons from other sources, you can continue to use the CODESYS Package Manager (menu 'Tools' > 'CODESYS Package Manager').
Description of behavior:
Add-ons from PLC Designer versions <V4.1 including V3 can be updated via the PLC Designer Installer. The <Change> button displays a red box showing how many add-ons from the respective PLC Designer version can be updated.
Conditions under which the behavior occurs:
If older versions of PLC Designer (V3, V4) are installed in addition to PLC Designer V4.1, the PLC Designer Installer can update the add-ons for these PLC Designer versions.
Affected products:
PLC Designer Installer from V4.1 onwards
Short-term measures, recommendations, assessment:
The add-ons for older PLC Designer versions must not be updated. This function has only been tested and approved with PLC Designer V4.1.
Updating add-ons from an older PLC Designer version could impair their functionality.
Downgrading an already updated add-on to its original version is not supported for older PLC Designer versions (<V4.1, V3). To install the original add-on versions, you must uninstall the corresponding PLC Designer and reinstall it.
