L5391/Display Handler MP - RG354686

Description

This block associates page handler function blocks with the real-world pages of a Multi-Page Operator Station (model number L5391).  There must be a unique page handler associated with each page.  Make sure the reference to each page handler is added to the display handler.

The Prev Page, Next Page and Set Page inputs control which page is currently displayed.  The Page output indicates which page is currently being displayed.  The default configuration for a multi-page operator station has one page with a selection band already defined.  This selection band has two buttons connected to the Prev Page and Next Page inputs of the display handler and the Page output is connected to a selection button which has 12 legends predefined for pages 1 through 12.

The Touch Screen may be disabled via configuration or via a logic signal.

A Screen Saver may be enabled which blanks the display after a period without touches (configurable from 0.1 to 100 minutes).  Once blanked, the screen may be reactivated by a touch (this works even if the touch screen is disabled).

Parameters

Page 'N'	Specifies a unique function block associated with each page ('N') to be displayed.

Set Page	Specifies a page to be displayed.  If the input is not a valid page, then the first page is displayed.

Prev Page	Displays the previous page before the current page.  If the current page is the first page, then the last page is displayed.

Next Page	Displays the next page after the current page.  If the current page is the last page, then the first page is displayed.

Get Page	Returns the current page being displayed.  Same as the Page output.

Touch Mode	Enables or disables the touch screen.  Expects either true (enable) or false (disable).

Get Touch Mode	Returns the touch screen mode:  Disabled or Enabled.

Screen Saver Delay	Configuration only.  Expects a value between 0.1 and 100 minutes.

Screen Saver	Enables or disables the screen saver.  Expects either true (enable) or false (disable).
