Detailed Description
2.9 Associated auxiliary functions
Auxiliary Function Output to PLC (H2)
2-26 Function Manual, 08/2005 Edition, 6FC5397-0BP10-0BA0
• 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.
NC/PLC interface signals
General information
In the case of an associated user-defined auxiliary function, the same signals are output to
the NCK/PLC interface as for the corresponding predefined auxiliary function. To distinguish
which auxiliary function has actually been programmed, the value of the user-defined
auxiliary function (Parameter: "Value") is output. This means it is possible to distinguish
between predefined and user-defined auxiliary functions in the PLC user program.
Note
A change to the following machine data may require adjustment of the PLC user program:
• MD22254 $MC_AUXFU_ASSOC_M0_VALUE
• MD22256 $MC_AUXFU_ASSOC_M1_VALUE
