6.3 Functions
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.
Subprograms
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.
External functions
Additional, user-specific functions can be integrated by means of external functions. The
external functions are stored in a DLL file and identified by an entry in the definition lines of
the configuration file.
PI services
The PI_START function starts PI Services (Program Invocation Services) from the PLC in the
NC area.
