1.14.2.23 TagSet Object (List)
Description
The object "TagSet" enables simultaneous access to several tags in one call. This features
better performance and lower communication load that single access to various tags.
Usage
Using the TagSet object, you may:
● Add tags to the list ("Add" method)
● Access tag objects contained in the list, and their properties ("Item" method)
● Write all tags of the list ("Write" method)
● Read all tags of the list ("Read" method)
● Remove single tags from the list ("Remove" method)
● Remove all tags from the list ("RemoveAll" method)
Tags in the list are accessed via:
'VBS169
Dim myTags
myTags = HMIRuntime.Tags.CreateTagSet
myTags("Tagname")
In order to have error-free read/write access to tags (tag objects) of the list, the respective tags
must exist in WinCC tag management.
If an error occurred during read/write access, the method used will return an error message
using the "LastError" and "ErrorDescription" properties.
