Pages
“Page” is used to refer to the screen data that is displayed on an HMI. You place objects on pages to
implement the required functions.
Pages and objects have the following three types of attributes.
The NA-series Programmable Terminals use event-driven applications in which the actions to perform
when events occur are specified. You can use events and actions to create more flexible applications
than is possible with conventional HMIs.
After you register a highly versatile subroutine as a global subroutine, you can call the subroutine from
anywhere in the project. This improves reusability and maintainability.
Also the use of Visual Basic allows you to reuse any of the many samples that are available on the
Internet to improve development productivity.
Attributes of pages and objects
Description
Properties
Properties set the appearance of an object or page, such as the position,
size, and color.
Animations
Animations set motion, such as blinking and movement.
Events and Actions
You can set events and the actions to perform when the events occur.
