Boundaries for macro function
Macros are used to define a character string replacement consisting of text only. This
replacement is made prior to execution of the replacement mechanism described here.
Boundary conditions
For subroutine calls with M, T, and D functions, the following supplementary conditions
apply:
• Only one function may be replaced for each part program line.
• A subroutine call must not be superimposed on M functions with predetermined meaning.
• In a part program block with an M, T or D function to be replaced, the following applies:
2-146
- No modal subprogram call can be active
- No subroutine return can be programmed
- No part program end can be programmed
Note
The M, T, and D values passed to the cycle have not yet been executed and must,
therefore, be programmed again in the cycle.
Specific tasks
Additional M function for program stop
Additional M function for conditional stop
