'Action on Page Activated' / 'Action On Page Deactivated' Dynamics

The 'Action On Page Activated' dynamic (only available for an HMI page and HMI page templates) with the selected action is triggered when the HMI page or HMI page template is activated or first loaded in the HMI application. The 'Action On Page Deactivated' dynamic with the selected action is triggered when the HMI page or HMI page template is deactivated in the HMI application.

For each dynamic, the following actions are available:

Action Description

Toggle value Toggles the Boolean variable assigned to the selected HMI tag.

Increment value Increments the variable value assigned to the selected HMI tag by the value set for the 'Step' (positive or negative value).

Write value Writes the value set in the 'Source variable' or 'Source constant' field to the 'Destination variable' value when the page is activated or deactivated. With 'Source Type' set to 'Constant', a constant is expected as 'Source constant'. With 'Source Type' set to 'Variable', an HMI tag of the data type expected by the 'Destination variable' must be entered as 'Source variable'.
