Hey all,

I am familiarizing myself with B&R's automation studio. I am using AS 3.0.71.10. I was looking at their coffee machine example, which utilizes a visualization. They are using a structured text program to control the visualization. There is an integer variable, which they have named 'setPage' that they use to switch pages in the visualization. I have also seen this similar technique used in the C language as well.

What i can't figure out is how that variable switches the page. Is it tied to another variable somewhere? When that integer is changes, where is it tied to the page index? I just can't figure it out.

Thanks in advance,

Brian

(* change page from global buttons *)
IF (gMainLogic.cmd.vis.newPage = 65535) AND (setPage <> setPageOld) THEN
IF (setPage = 0) THEN
setPage := setPageOld;
ELSE
gMainLogic.cmd.vis.newPage := setPage;
setPageOld := setPage;
END_IF
END_IF

This is the code that links the setPage to the global variable.
That global variable is linked to the page ChangeDataPoint. Open the 'visu' and check the properties.
