When opening a new screen the old tag values are shown.
The old E-panel that I have replaced did not show the analog numeric fields until all the dynamic tags had retrieved new values from the PLC. I want the X2 pro panel to do the same thing or show zero until the new tag values have been retrieved.

Updating tag values from PLC more often and static “Always Active” will probably slow down performance of the PLC too much.
Is there any way to clear all dynamic tag values when they are not in use? Or anything else I can do to fix this problem?

Hi X-Anders,
if you are only using one controller you may be able to solve this by attaching a small script to the value change event of the systemtag Communication Errors. If this value is not 0 then you could go through and set the desired tags to 0 values until the PLC comes back.
