3.2 Parameterizing the control using machine data
3.2.1 Machine data for setting actual value, scratching, PRESET
Access levels for system frames
The machine manufacturer or user can assign the access levels for system frames as well
as for individual functions and data areas using display machine data. Access levels 0 to 3
can also be entered.
Default setting: This machine data is predefined with access level "7". This means that
access is granted to all these data areas and functions when the keylock switch is in the 0
position.
Access levels are available for the following system frames:
System frame
ToolFrame
PartFrame
WPFrame
CYCFrame
TraFrame
ExtFrame
SetFrame
Function
The behavior of the Scratching and Set actual value, PRESET functions is influenced by a
number of machine data. The selected settings affect operation (how softkeys and values
are displayed, and how the entered values are stored).
With the introduction of system frames, two variants are available for the functions. The
variants are differentiated by a channel-specific machine data:
