Tag Functions Overview

Tag functions provide browse, add, modify, and delete access to the configured tags on a server. You can retrieve the properties for each tag with User API calls. For example, you can retrieve user-defined collection parameters for a tag before collection, or retrieve user-configured display parameters to prepare for plotting.

You can retrieve string and numeric tag properties. Every tag property is classified as string or numeric (double float). For example, Boolean properties are converted to double float and time data type properties are converted to string.

You can add, delete, or modify tags using the User API.

You can browse tags in three different ways. The simplest mode uses ihuFetchTagCache to filter by tagname. To filter by additional properties. such as data type or collector name, use ihuFetchTagCacheEx. Finally, to browse in multiple browser windows at the same time, for example, to compare the tags on one server with those on another server, use ihuFetchTagCacheEx2 or ihuFetchTagCacheEx3.
