The user can also send back the number of a dialog text line and a function result
(to DB 40).Both values returned refer to the function number of the softkey pressed. The
dialog text line number and/or function result must be entered in the same PLC cycle in which
the SOFTKEY FUNCTION NUMBER is made available in DB 40/DW 49. In this way, dialog
texts can be displayed at the operator panel and/or subsequent menus stated that also have to
be generated via a programming workstation.
If a softkey with configured softkey function number is pressed on the operator panel, this
SOFTKEY FUNCTION NUMBER is transferred (DW 41) and a strobe bit (DB 40, DW 49,
bit 14) set to "1".
The user can now obtain the function number and send back a function result (DL 50) and a
dialog text number (DR 50) to DB 40 in the same PLC cycle; these are declared valid by
means of an acknowledgement bit (DB 40, DW 49, bit 15).
