Compensation memory structure

Tool offset memory size
Each channel can have a dedicated tool offset memory (TO unit).
Which tool offset memory exists for the relevant channel is set with the machine data:
MD28085 $MC_MM_LINK_TOA_UNIT (assignment of TO unit to a channel)
The maximum number of tool cutting edges for all tools managed by the NC is set with the
machine data:
MD18100 $MN_MM_NUM_CUTTING_EDGES_IN_TOA (number of tool cutting edges in NC)
Tools
The tool offset memory consists of tools numbered T1 to T32000.
Each tool can be set up via TOA files or individually, using the "New tool" softkey. Offset values
not required must be assigned the value zero. This is the default setting when the offset
memory is created. The individual values in the offset memory (tool parameters) can be read
and written from the program using system variables.
Note
The tools (T1 to T32000) do not have to be stored in ascending order or contiguously in the tool
offset memory, and the first tool does not have to be assigned number T1.
