DB21, ...
DBB158 - DBB193
F functions 1 to 6
Extended address F functions 1 to 6
Edge evaluation: No Signal(s) updated: job-controlled by NCK
Signal state 1 or
edge change
0 → 1
Up to 6 F functions (one path feed and up to 5 axis-specific feeds for
positioning axes) are made available here simultaneously as soon as the F change
signals are available.
Value range of F function: Floating point (corresponding to the MC5+format)
Value range of the extended address: 0 to 18; integer number
The extended address of the F function is generated from the feed type (path feed or axis-specific
feed) and the axis names.
It is coded as follows:
The F functions remain until they are overwritten by new F functions.
Signal state 0 or
edge change
1 → 0
• After the PLC has ramped-up.
• All help functions are deleted before a new function is entered.
Application
example(s)
Control of programmed F word by the PLC, e.g. through overwriting of the set feed rate override.

DBB194 - DBB206 Dynamic M functions: M0 - M99
Edge evaluation: No Signal(s) updated: job-controlled 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
DB21, ...
DBX318.5 Associated M01/M00 active
Edge evaluation: No Signal(s) updated:
Signal state 1 or
edge change
0 → 1
This bit indicates that an M00 or M01 help function is active if the appropriate associated M00 and
M01 (help functions) were enabled/activated beforehand.
Signal state 0 or
edge change
1 → 0
No associated M00/M01 help functions active.
Corresponding to ... DB21, ... DBX30.5 (activate associated M01)
