About the Tag Converter Wizard
The tag converter wizard (TCW) requires core information from an
existing application to perform the conversion.:
•
Exported HMI tag database
•
Exported displays (xml format)
•
Exported alarms (xml format)
When this pre-conversion information is available, you can run the
wizard. The wizard examines the HMI tag database to determine
which tags to convert to alias tags or direct reference tags.
The HMI tags are substituted with the alias or device tags in the
display and alarm xml files. When the conversion is done, a
Convert_Log.txt file is generated. This file indicates all tag
substitutions on a display-by-display basis. A new set of display and
alarm xml files is created that you can import into your migrated
application. The original display and alarm xml files are unaltered.
IMPORTANT
HMI tags that use custom scale and offsets are not converted.
Any alias tags with initial values assigned are not converted.
You must manually set the custom scale, offsets, and initial
values for these tags, for objects to operate correctly.
IMPORTANT
The tag converter wizard converts HMI tags to device tags. It
does not convert device tags to HMI tags. Back up your
application before starting the conversion. The conversion does
alter you original displays when imported into your new
application.
