Mode groupspecific interface signals
The exchange of mode groupspecific signals to/from the mode group is transferred to DB11
in the user interface. In this way, the mode group can be monitored and controlled from the
PLC or NCK.
The following table lists all mode groupspecific interface signals:
Modegroup signals (PLC => NCK)
Mode group Reset
Mode group Stop axes plus spindles
Mode group Stop
Mode change
Operating mode: JOG, MDA, AUTOM.
Single block: Type A, Type B
Machine function:
REF, REPOS, TEACH IN,
Change in mode group
A change in the configuration of a mode group with respect to its assigned channels requires
a subsequent POWER ON.
The change is made via machine data:
MD10010 $MN_ASSIGN_CHAN_TO_MODE_GROUP.
Mode group numbers must be assigned contiguously starting with 1.
Machine data
There are no mode groupspecific machine data.
Basic logic functions: Mode group, channel, program operation, reset response (K1)
