Signal state 0 The signal is set to 0 as soon as processing takes place in the channel, e.g.:
a program is being executed or block search.

DB3300
DBX4.2
All axes referenced
Signal(s) from channel (PLC → NCK)
Edge evaluation: No Signal(s) updated: Cyclic
Signal state 1 All axes that must have a reference point have been referenced.
(Note for axes that must have a reference point:
MD34110 REFP_CYCLE_NR, MD20700 REFP_NC_START_LOCK)
Signal state 0 One or more axes of the channel have not been referenced.
Special cases, errors, ... The spindles of the channel have no effect on this IS.
Corresponding to ... IS "Referenced/synchronized 1" (DB390x DBX0.4)

DBX4.3
All axes stationary
Signal(s) from channel (NCK → PLC)
Edge evaluation: No Signal(s) updated: Cyclic
Signal state 1 All axes assigned to the channel are stationary with interpolator end. No
other traversing motions are active.

DBX4.6
Channel-specific NCK alarm is active
Signal(s) from channel (PLC → NCK)
Edge evaluation: No Signal(s) updated: Cyclic
Signal state 1 At least one NCK alarm is present for the channel.
Thus the following group interface signal is also set:
DB2700 DBX3.0 (NCK alarm is present)
The PLC user program can interrogate whether processing for the channel
in question has been interrupted because of an NCK channel:
DB3300 DBX4.7 (NCK alarm with processing stop active).
Signal state 0 No NCK alarm is present for the channel.
Corresponding to ... DB3300 DBX4.7 (NCK alarm with processing stop active)
DB2700 DBX3.0 (NCK alarm present)
Note for the reader /DA/ Diagnostics Guide
DB3300
DBX4.7
NCK alarm with processing stop active
Signal(s) from channel (PLC → NCK)
Edge evaluation: No Signal(s) updated: Cyclic
Signal state 1 At least one NCK alarm, which is causing a processing stop of the part pro‐
gram running in the channel, is active.
Signal state 0 There is no alarm active for the channel that is causing a processing stop.
