2.7 Functions
2.7
Overview
A variety of functions are available in dialogs and dialog-dependent softkey menus. These
can be activated by specific events (exit input field, actuate softkey) and configured in
methods.
Subroutines
Repeatedly used configuring instructions or others, which define the process for a particular
operation can be configured in subprograms. Subprograms can be loaded into the main
program or other subprograms at any time and executed as often as necessary, i.e., the
instructions they contain do not need to be configured repeatedly. The definition blocks of
the dialogs/softkey menu constitute a main program.
PI services
The PI_SERVICE function can be used to start PI Services (Program Invocation Services)
from the PLC in the NC area.
External functions (only HMI Advanced)
Additional, user-specific functions can be integrated by means of external functions. External
functions are stored in a DLL file and identified by an entry in the definition lines of the
configuration file.
