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 MD number Designation/meaning
ToolFrame 9183 $MM_USER_CLASS_WRITE_TOOLFRAME
Protection level write toolholder
PartFrame 9184 $MM_USER_CLASS_WRITE_PARTFRAME
Protection level write tool reference point
WPFrame 9185 $MM_USER_CLASS_WRITE_WPFRAME
Protection level write workpiece reference point
CYCFrame 9186 $MM_USER_CLASS_WRITE_CYCFRAME
Protection level write cycle frame
TraFrame 9187 $MM_USER_CLASS_WRITE_TRAFRAME
Protection level write transformation frame
ExtFrame 9188 $MM_USER_CLASS_WRITE_EXTFRAME
Protection level write external WO
SetFrame 9210 $MM_USER_CLASS_WRITE_ZOA
Protection level write settable WO
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:
MD 28082: $MC_SYSTEM_FRAME_MASK
Bit:
0 Actual value setting, scratching
1 External work offset
2 TCARR, PAROT
3 TOROT, TOFRAME
