Tags of technology objects
Certain tags of technology objects are retentive, for example adjustment values of absolute
encoders. STEP 7 automatically manages the retentivity of technology object tags, so you do
not have to configure their retentivity.
The retentive tags of technology objects are unaffected by a memory reset. They can only be
deleted by resetting to factory settings.
Reference
You can find additional information on configuring retentivity in the STEP 7 online help.
