11.6 Data transfer: System memory into R parameter
11.6 Data transfer: System memory into R parameter
The main group 3 is organized as follows:
@
3 x y Three-digit @ code
Special function
0: Machine data
1: Setting data
2: Tool offsets
3: Zero offsets
4: Programmed setpoint values
5: External setpoint values (available soon)
6: Actual values
7: Program data
3: Main group 3
All @ commands in main group 3 have <Var> as first notation. This defines directly or via a
pointer an R parameter in which the contents of the addressed system cell are to be loaded.
