Display of differences in parameter sets after loading the source code from the controller (fixed as of V3.21)

Corrected from:
PLC Designer V3.21
 
Response of the new version:
If the controller detects differences in the field device data when going online, these are displayed under Details in the "Field device data have changed" dialog.
 
What happens?
When going online, the "Field device data have changed" dialog appears. 
Under <Details>, there are, however, no entries listed.
For the SoftPLC parameters, the message 'Unknown date in PLC Designer and controller' appears.
 
When does this behaviour occur?
The behaviour occurs if a source code has been loaded from the controller (menu File>Source upload) which has been compiled with a compiler V3.5.7.51 (current version of PLC Designer V3.13) and going online on a controller with a PLC Designer version > V3.13.
 
Which products are affected?
PLC Designer from V3.14
 
Short-term measures:
If the "Field device data have changed" dialog appears when logging in after loading the source code from the controller, use PLC Designer V3.13 for logging in.
 
Evaluation/recommendations:
The PLC Designer can be used to transfer the source code to the controller. In the event of servicing, this may be helpful because it allows you to directly load the source code from the controller and use it to monitor the variable values in the controller. Due to the above function restriction, the PLC Designer reports parameter set differences when going online with the controller. This leads to unnecessary uncertainty since there are no differences in this case.
