Detailed Description
2.11 Response to overstore
Auxiliary Function Output to PLC (H2)
2-28 Function Manual, 08/2005 Edition, 6FC5397-0BP10-0BA0
Constraints
If a subroutine called indirectly via an M function in a part program in one of the following
ways, no preprocessing stop is performed:
• MD10715 $MN_M_NO_FCT_CYCLE (M function to be replaced by subroutine)
• M98 (ISO dialect T / ISO dialect M)
2.11 2.11 Response to overstore
Overstore
On the SINUMERIK HMI operator interface, the following functions:
• NC START of a part program
• NC START to resume an interrupted part program
the auxiliary functions that are output with the start, can be changed with the "Overstore"
function. Possible applications include:
• Addition of auxiliary functions after block search
• Restoring the initial state to position a part program
Types of auxiliary functions that can be overstored
Basically, the following types of auxiliary functions can be overstored:
• M (special function)
• S (spindle speed)
• T (tool number)
• H (aux. function)
• D (tool offset number)
• DL (additive tool offset)
• F (feed)
Duration of validity
An overstored auxiliary function, e.g. M3 (spindle right) remains valid, until it is overwritten by
another auxiliary function of the same auxiliary function group by overstoring again or by
programming in a part program block.
