Function block “Disp_DisplayPage”
For each variable you define its use, i.e. text display or value entry.
The inputs of the function block must be parameterised for this
purpose. Function block “Disp_DisplayPage” supports the cursor
control function. If several variables requiring a value entry are
shown, the first entry position is marked by a cursor. After the
entry is completed, the cursor moves to the next position. An
application involving several screens and the calling of one screen
can be implemented in the user program. For this use the rocker
buttons P1, P2, P3, P4 and the ESC, DEL, ALT and OK buttons for
which the status can normally be scanned in the program.
Information on the menu display, current cursor position and
button status is indicated by the outputs of the
“Disp_GetDisplayInfo” function block.
The “Disp_DisplayElement” and “Disp_DisplayPage” function
blocks are used for defining elements. The term “element” refers
to the function blocks. An element is a variable that has additional
properties such as the positioning on the display. The additional
properties are defined by the parameters assigned to the function
block inputs.
Other functions are shown in the function/function block
overview.
