Introduction
The HMI extension (Human Machine Interface) provides access for interacting with the user through the display of graphical screens. To achieve this goal, there are two ways to operate with screens:
- Basic Screen - A set of basic dialogs providing by the operating systems
- Custom Screens - Customizable screens that allow arbitrary flexibility
Custom screens only define an interface to a screen. The screen itself is externally created. The layout and functionality of this screen is not defined in the OTX. The interface to the screen is the OTX Screen Signature. A Screen Signature defines all IN-, OUT- and INOUT-Parameters of a screen. The OTX Runtime have to map the Screen Signature Parameters to the proper screen controls. The OTF supports two kinds of Custom Screens:
Generic Screen
As the name said, Generic Screen is completely data driven. Only the Screen Signature have to define. The default layout can be used or the layout can be adapted.
