Tag Security

Tag Access Rights

Tag security is often the best way to configure security for data access. By defining security on a Tag, you affect the Tag across all windows in all projects, as opposed to configuring component security on each component that displays or controls that Tag.

If a user opens a window in the Client that has components that are bound to a Tag that the user doesn't have clearance to read or write to, the component will get a forbidden overlay.

To Set the Access Rights to a Tag

You can add read/write security to individual Tags or multiple Tags in the Designer. In order to change permissions on a Tag, you have to make changes in two places. 1) Set the Access Rights property to Custom. 2) Add Role(s) to the Permissions page.

1. In the Tag Browser, edit a Tag by double-clicking on the Tag.
    
2. In the General tab, from the Access Rights drop-down, select Custom.
   
   
    
3. Select the Permissions tab on the left side, and from the Add a Role drop-down select a role. Click the Add button.
    
4. Change each role's Access rights by selecting the Read Only or Read/Write option. If a user does not have any of the listed roles, they will be denied both read and write permissions.
   
   
    
5. Click OK. Now the user has the Read/Write permission to interact with the Tag.
