Detailed Description
2.10 M function with implicit preprocessing stop
Auxiliary Function Output to PLC (H2)
Function Manual, 08/2005 Edition, 6FC5397-0BP10-0BA0
2-27
Specific NC/PLC interface signals
The following specific NCK/PLC interface signals are available:
• DB 21, ... DBX318.5 (associated M00/M01 active) Check-back signal
• DB 21, ... DBX30.5 (activate associated M01) Activation signal
Example
Associating the user-defined auxiliary functions M123 with M0:
MD22254 $MC_AUXFU_ASSOC_M0_VALUE = 123
The user-defined auxiliary function M123 has the same functionality as M0 (stop).
Constraints
Please note the following boundary conditions:
• A user-defined auxiliary function may not be multiply associated.
• Predefined auxiliary functions (e.g. M3, M4, M5 etc.) must not be associated.
2.10 2.10 M function with implicit preprocessing stop
Function
Triggering a preprocessing stop in conjunction with an auxiliary function can be programmed
via the STOPRE part program command. Triggering a preprocessing stop in conjunction with
an M function can be programmed explicitly via the STOPRE part program command.
Always triggering a preprocessing stop in M function programming can be parameterized for
each M function via the following machine data:
MD10713 $MN_M_NO_FCT_STOPRE (M function with preprocessing stop)
Preprocessing stop with M function M88
The user-defined M function M88 is intended to trigger a preprocessing stop.
Parameterization
MD10713 $MN_M_NO_FCT_STOPRE [ 0 ] = 88
Application
Part program (extract)
Programming Comment
N100 G0 X10 M88 ; Traverse movement and implicit preprocessing stop via M88
N110 Y=R1 ; N110 is only interpreted after completion of the traverse
; movement and acknowledgment of the M function.
