Subprogram Call Up Function (M98, M99) - Siemens Sinumerik 802D sl Programming Manual

Enhanced Level Commands
4.2 Program support functions (2)
Note
Use of this command in a program allows the tool to advance little by little. This
command can also be used to input offset values one at a time from a program by
specifying this command successively instead of inputting these values one at a
time from the MDI unit.
Example of programming
G10 P16 X32.5 W0.05 ;

Setting the workpiece coordinate system shift data
With the commands of "G10 P00 X (U) ⋅⋅⋅ Z (W) ⋅⋅⋅ C (H) ⋅⋅⋅ ;", it is possible
to write and update the workpiece coordinate system shift data using a part pro-
gram. If an address is omitted in the designation of data input block, the offset
amounts for the omitted addresses remain unchanged.
4.2.2

Subprogram call up function (M98, M99)

This function can be used when subprograms are stored in the part program me-
mory. Subprograms registered to the memory with program numbers assigned can
be called up and executed as many times as required.
The created subprograms should be stored in the part program memory before
they are called up.
