PI service
Function which, on an NC, executes a clearly defined operation. PI services can be called from
the PLC and the HMI system.
PLC hard key
PLC hard keys are provided via the PLC interface of the HMI software, just like hotkeys. The
functions, which can be triggered via the user interface, can be configured.
They take the form of MCP keys or evaluations of PLC signal logic operations in the PLC user
program. For this reason, they are referred to as "virtual keys".
Programming support
Provision of → Dialogs to assist programmers in writing → Parts programs with "higher-level"
components
Properties
Characteristics of an object (e.g of a → Variable)
Recompile
NC code sections can be generated in a → Part program from input fields in → Dialogs in the
→ Programming support system. Recompilation is the reverse operation. The input fields used
to generate a selected section of NC code are retrieved from the NC code and displayed in
the original dialog.
Selecting
A program formulated in the NC language, which specifies motion sequences for axes and
various special actions.
Simulation
Simulation of a → Parts program run without movement of the actual machine axes.
