 In the Graphics editor, create a graphic object and then attach touch animation with
the DerivedOff <component> command as the object’s action. When the object is
touched, derived tags processing stops.
 For the Logout Macro in the FactoryTalk View SE User Accounts editor, specify the
DerivedOff command, or a macro that contains the command.
 For the Shutdown command in the Display Settings Behavior tab, specify the
DerivedOff command, or a macro that contains the command.
Setting up FactoryTalk View SE events
Events are expressions that trigger actions:
 Expressions are equations containing tag values, mathematical operations, if–then–
else logic, and other built-in FactoryTalk View functions. For information about using
expressions, see Chapter 20, Creating expressions.
 Actions are FactoryTalk View commands, symbols, or macros. For example, an action
could initiate a snapshot of tag values using the DataLogSnapshot command, or
change a tag value using the Set command.
An events component is a file that contains the definitions of one or more events. An
events component can be run when an HMI server starts, or it can be run using the
EventOn command after the HMI server has started.
Parts of the Events editor
Use the Events editor to set up events processing for an application.
To open the Events editor
1. In FactoryTalk View Studio, in the Explorer window, open the Logic and Control
folder.
2. Right-click the Events icon, and then click New.
You can also open the Events editor by dragging its icon into the FactoryTalk View
Studio workspace, or by double-clicking an existing Events component.
Events are detected at the FactoryTalk View SE Server (also called the HMI server);
therefore, commands that run only at the FactoryTalk View SE Client are ignored when
issued by an event expression. For a list of these commands, see Appendix A, FactoryTalk
View commands.
