About navigation buttons
Use the navigation button object to create buttons to navigate between previously viewed graphic displays. FactoryTalk View SE can maintain a navigation history of displays that are viewed, and the navigation buttons let you browse back to a previous display and forward to the next.
Each navigation button performs a single function at runtime, with the option to display the previous screen, the next screen, or the navigation history. Multiple navigation buttons can be added in a group to resemble the functionality of navigation buttons in a web browser, letting you move back, move forward, and view history.
Navigation history is optional, and is configured for each client. To track displays, you have to
- Activate the display navigation functionality using the FactoryTalk View SE Client.
- Specify what displays to track using the Properties tab in the Display Settings for each display.
This provides flexibility in tracking only the displays you specify.
Navigation buttons can be active or inactive at runtime. A button’s active or inactive state depends on both the configured action of the button and the position of the currently opened graphic display in the navigation history list. For example, if the button is configured to display the next graphic display and the currently displayed graphic display is the first one in the navigation history list, the button is inactive because there is no ‘next’ display to go to. When the currently displayed graphic display is not the first one in the navigation history list, the button is active.
When a button is active, clicking it starts the corresponding action. When a button is inactive, clicking it causes no response.
