Events

event

occurs at runtime to indicate that a certain situation has occurred. An action or method is then performed. Both users and the system can cause events on the HMI device. For example, an event can occur when the user clicks the mouse button. The system can also trigger events. For example, an event could occur when a graphic element enters a specific state, such as a color changing values.

Events include:

Mouse click

Mouse down

Mouse up

Load project

Variable value changes

Variable value meets specified condition

Variable value is out of specified range

Events perform methods to create application logic. Add a method to an event and configure that method to have the event perform the method at runtime. For each event, you must configure one or more methods to perform. When the event is triggered, the configured method occurs. Methods, dependent on type of event and element, include:

Create object

Create variable

Delete node

Increment value

Set bit value

Set variable value

Toggle value

Toggle bit

Open dialog

Acknowledge all active alarms

Confirm all active alarms

Change user
