I have WinCC project (version v6.2) and some tags are wrong.
These tags are structure tags.
I want to modify these tags but I can't do anything.
How can we modify structure tags?

Re: [?]: WinCC Structure Tags???
It' easy and hard. To modyfy a structure tag, seems modify all structured tag into project.
Before modify you need check if the wrong tag are the same tag for every structure.
for example you have a structure tag named ANALOG_IN
Under ANALOG_IN , you have zero, range, out ecc
Your tag are
ANALOG_IN.zero
ANALOG_IN.range
ANALOG_IN.out
Where ANALOG_IN is the tagname create during contruction of the tag
for example you have LIT2011 tag name and PI1234
LIT2011.zero
LIT2011.range
LIT2011.out
PI1234.zero
PI1234.range
PI1234.out
if read LIT2011.zero correct and not read PI1234.zero , this seem the problem in into plc not in the structured tag
Before change a structurated tag you need to go into Stucture , delete all the tag, and them click over stucture and modify.
After rebuild the tag whit a modified structure
