Description: Defines the number of user variable names for channel-specific global user data (GUD).
Approximately 80 bytes of memory are reserved in the SRAM for each variable name. The
additional memory required for the value of the variable is equal to the size of the
data type of the variable multiplied by the number of channels. This means that each
channel has its own memory available for the variable values. The number of available
channel-specific global user data is exhausted on reaching the limit value set in
MD18130 $MN_MM_NUM_GUD_NAMES_CHAN or MD18150 $MN_MM_GUD_VALUES_MEM (memory space for
user variables).
The name created with the DEF statement is valid for all channels.
The memory requirement for the variable value is equal to the size of the data type
multiplied by the number of channels.
Buffered user memory is used.
Special cases:
The battery-backed data are lost if this machine data is altered.

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
