For information about creating HMI memory tags, see Chapter 7.
Steps for using HMI tags
To use HMI tags, complete two basic steps:
1. In the Tags editor in FactoryTalk View, create a tag. HMI tags can be used as an
internal storage location. Optionally you can map the tag name to an OPC tag or
device address.
For more information, see Chapter 7.
2. In graphic displays, alarm triggers, or anywhere else you want to use a tag’s value,
assign the tag. At run time, the tag’s value is passed to the graphic display or alarm
system.
Browse for tags
You don’t have to remember the path and name of a tag to use it in your application.
Whenever you need to use a tag, you can open the Tag Browser and select the tag to use.
To open the Tag Browser
 In most editors, click the Browse button in the Tags column.
 In the Expression editor, position the cursor where you want to insert a tag name, and
then click Tags.
 In the Parameters editor, double-click where you want to insert a tag name.
