Description: The specified value reserves memory space for the variable values of the global user
data (GUD). The
dimensioning of the memory depends to a large extent on the data types
used for the variables.
Overview of the memory requirements of the data types:
Data type Memory requirement
REAL 8 bytes
INT 4 bytes
BOOL 1 byte
CHAR 1 byte
STRING 1 byte per character, 100 characters permitted per string
AXIS 4 bytes
FRAME up to 1KB depending on control model
The total memory required by a channel or axis-specific global user variable is the
memory
requirement
of
the variables multiplied by the number of channels or axes. The
number of global user variables available is given when the limit defined in MD18120
$MN_MM_NUM_GUD_NAMES_NCK, MD18130 $MN_MM_NUM_GUD_NAMES_CHAN, MD18140
$MN_MM_NUM_GUD_NAMES_AXIS or MD18150 $MN_MM_GUD_VALUES_MEM is reached.
Buffered user memory is used.
Special cases:
The buffered data are lost if this machine data is altered!
