OPC UA - Data type change of the diagnostics parameter "Active Setting" (with old PLC Designer project and new firmware)


Compatibility with previous versions:  
If a PLC-Designer project (based <V1.13) is loaded on a controller with a firmware of V1.13, the values of indexes 0x2472:11-14 and 0x2473:11-12 are not displayed in EasyStarter.


Background:
The value range of the "Active Setting Parameter" had to be extended - so that it is identical to the settings parameters.
Specifically, this concerns the indexes 0x2472:11-14 and 0x2473:11-12, where the data type of the parameters was changed from unsigned integer to unsigned double integer (in order to cover a larger data range).

These parameters are not displayed in EasyStarter when using a controller firmware >= V1.13 if the application was created with a controller device description file (devdesc) < V1.13.

However, the parameters are displayed correctly on the PLC Designer pages.


Workaround:
Translate the PLC Designer project with the appropriate device description V01.13 and the changed data types.
