Example:
$MC_MM_SYSTEM_FRAME_MASK = 'B001101' means that
there are three system frames; one for PRESET, one for PAROT and one for TOROT and TOFRAME.
The system frame mask is used to define if the corresponding function has a system frame. With non-configured
frames, in certain circumstances the function will be rejected with an alarm.
System frames in data management
The system frames are stored in the static NC memory and can, therefore, be archived and reloaded. System
frames in data management can be read and written in the program using the following variables:
System variables Significance
$P_SETFR System frame for PRESET and scratching (SetFrame)
$P_EXTFR System frame for zero offset external (ExtFrame)
$P_PARTFR System frame for TCARR and PAROT (PartFrame)
$P_TOOLFR System frame for TOROT and TOFRAME (ToolFrame)
$P_WPFR System frame for workpiece reference points (Work-Piece-Frame)
$P_CYCFR System frame for cycles (Cycle-Frame)
$P_TRAFRAME System frame for transformations (Transformation Frame)
$P_ISO1FR Frame for G51.1 mirroring (ISO)
$P_ISO2FR Frame for G68 2DROT (ISO)
$P_ISO3FR Frame for G68 3DROT (ISO)
$P_ISO4FR System frame for G51 scale (ISO)
$P_RELFR System frame for relative coordinate systems
All write operations to these frames must be executed using system functions. For cycle programmers, it has
been made possible to write the frames using the above variables. Attempts to write to a non-configured system
frame are rejected with the alarm "Channel %1 block %2 name %3 not defined or option not available".
System frames in the data management are either activated directly with the system function (TOROT, PAROT,
etc.), or with a G500, G54 to G599 instruction.
Active system frames
The active system frames are the frames, which are active in the main run. An appropriate current system frame
exists for each current system frame in the data management. Only with the activation of the data management
frame are the values taken into account with regard to the preprocessing.
