2.9 Associated auxiliary functions
Function
Associated auxiliary functions are user-defined auxiliary functions that have the same effect
as the corresponding predefined auxiliary functions. For the following predefined auxiliary
functions, user-defined auxiliary functions can be associated:
• M0 (Stop)
• M1 (conditional stop).
Requirements
The precondition for association of a user-defined auxiliary function with one of the
predefined auxiliary functions mentioned is parameterization of a user-defined auxiliary
function. Only "M" is allowed as a "type" parameter of the user-defined auxiliary function.
Parameterization
Association of a user-defined auxiliary function with one of the predefined auxiliary functions
mentioned is set in the following machine data:
• MD22254 $MC_AUXFU_ASSOC_M0_VALUE (additional M function for program stop)
• MD22256 $MC_AUXFU_ASSOC_M1_VALUE (additional M function for conditional stop)
Group assignment
The group assignment of an associated user-defined auxiliary function is always the group
assignment of the corresponding predefined auxiliary function.
Application
Associated auxiliary functions can be used in:
• Main program
• Subroutine
• Cycle
Note
Associated auxiliary functions may not be used in synchronized actions.
