Available in all applications, although most tags that use this method are VTScada-based only.
Used by: DriverMux (driver multi-plexer) tag.
The Driver Select drawing method is used to provide operators with a means to select one of the configured drivers to use exclusively, or to allow the DriverMUX tag to work automatically.

The graphic editor to configure the Driver Select drawing method is as follows:

(Click title to expand text)
The Tag field displays the name and description of the tag that is currently associated with this drawing method. You can use this to select a different tag or parameter to use as the data source for this drawing method.
The Tag field is only present when editing a completed drawing method object
Label for 1st, 2nd and 3rd radio buttons
The function of each radio button is defined within the drawing method. The default labels describe these functions well, but you may choose to use your own labels for each.
Show bevel around radio buttons
Adds a decorative edge to the cluster of three buttons. When the bevel is shown, you may also add a title.
Available only when the bevel is shown around the radio button cluster. If you have more than one DriverMux tag in your application, it would be appropriate to make the title describe which is being affected by the operator’s choices.
