Fundamentals
3.3 Defining start softkeys
Reverting to the standard application
You can exit the newly created user interfaces and return to the standard application.
You can use the <RECALL> key to close new user interfaces if you have not configured this
key for any other task.
Note
Calling dialogs in the PLC user program
Dialogs can be selected from the PLC as well as via softkeys: An interface signal is available
in DB19.DBB10 for signal exchange between the PLC → HMI.
3.3 Defining start softkeys
Dialog-independent softkey
Start softkeys are dialog-independent softkeys which are not called from a dialog, but which
have been configured before the first new dialog. In order to access the start dialog or a start
softkey menu, the start softkey must be defined.
Programming
The definition block for a start softkey is structured as follows:
//S(Start)
HS1=(...)
PRESS(HS1)
LM...
END_PRESS
//END
22
; start identifier of start softkey
; defining the start softkey: horizontal SK 1
; method

; end of method
; end identifier of start softkey
