Implementing Tag-Level Security
About this task
Set tag level security in Historian Administrator. You need the Historian Security Groups to implement tag-level security. You can use a Windows pre-defined group (power users, for example) or create your own separate group specifically for this function. For more information on creating and adding groups, refer to Setting Up Historian Security Groups.
Users must have iH Security Admins rights to set individual tag level security, browse, or query tags in Historian Administrator.
Procedure
- Access Configuration Hub.
-
In the NAVIGATION section, under the Configuration Hub
plugin for Historian, select Tags.
A list of all the tags appears.
-
Select the row containing the tag whose security you want to define.
The tag details appear in the DETAILS section.
-
Enter values as described in the following table.
Field Description Read Group The Windows security group that can retrieve the tag data and plot it in a trend chart. For example, if you select a group with power users, in addition to members of the iH Security Admins group, only a member of the power users group will be able to read data for that tag. Even a member of the iH Readers group will not be able to access data for that tag, unless they are also defined as a member of the power users group.
Write Group The Windows security group that can write tag data (for example, using the Excel Add-in for Historian). Administer Group The Windows security group that can create, modify, and delete the tag. Note: If you are using domain groups (instead of local groups), the Read Group, Write Group, and Administer Group fields contain only the groups whose names begin with iH<space> (case-sensitive). Therefore, ensure that the group that you want to use begins with iH<space>.
