Basic logic functions: NC/PLC interface signals (Z1)

DB21, ...
DBX318.0 ASUB is stopped
Edge evaluation: no Signal(s) updated: cyclic
Signal state 1 or
edge change
0 → 1
The signal is set to 1 if the control stops automatically prior to the end of the ASUB.
The NST DB21, ... DBX318.0 (ASUP is stopped) is supplied only for the case "Interrupt in a
program mode and channel status stopped".
Signal status 0 or
edge change
1 → 0
The NST DB21, ... DBX318.0 (ASUP is stopped) is set to 0 at Start and Reset.

ASUB with REPOSA
is triggered in the
status AUTOMATIC
mode stopped
If the interrupt routine is ended with REPOSA, then the following sequence is typical:
• The part program is stopped using the stop key, stop-all key or as a result of an alarm.
• The controller assumes program status "Stopped".
• The PLC initiates an ASUB via block FC9.
• Before the re-approach to the contour, the controller stops and goes to program status
"Stopped". NST DB21, ... DBX318.0 (ASUP is stopped) is set.
• The user presses Start. The NST DB21, ... DBX318.0 (ASUP is stopped) is set back, the repeat
approach movement is started.
• At the end of the re-approach motion, the FC9 signal "ASUB done" is set and the path of the
interrupted part program is continued.
