DBB194 - DBB206
Dynamic M functions: M0 - M99
Edge evaluation: no
Signal(s) updated: Jobcontrolled by NCK
Signal state 1 or
edge change
0 → 1
The dynamic M signal bits are set by decoded M functions.
Signal state 0 or
edge change
1 → 0
For a general help function output, the dynamic M signal bits are acknowledged by the PLC basic
program after the OB1 has been completely run-through (executed once).
For a fast help function output, after the PLC identifies the help functions, they are acknowledged in
the same OB40 cycle.
Application
example(s)
Spindle clockwise/counterclockwise rotation, switch coolant ON/OFF

help function is active if the appropriate associated
M00
and
M01
(help functions) were enabled/activated beforehand.

Value of F help function
Edge evaluation: no
Signal(s) updated: Jobcontrolled
The values of the F help functions for positioning axes are stored here. The axis to which each
value applies is determined by the extended address.
