About tags
Tags are used to identity pieces of equipment. There is a tag hierarchy, which means there can be a tag for an entire machine as a whole, but the individual parts of the machine can also have tags.
-
Tag numbers are unique within a site.
-
A tag is always imported into AVEVA™ Operational Safety Management from an external system.
Values
Each tag has associated values.
-
Values are imported along with tag.
-
These values cannot be changed in AVEVA™ Operational Safety Management.
