Signal state 1 or The signal is set to 1 if the control stops automatically prior to the end of the ASUB.
edge change The NST DB21, ... DBX318.0 (ASUP is stopped) is supplied only for the case "Interrupt in a

Signal(s) updated: cyclic
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.
Basic logic functions: NC/PLC interface signals (Z1)
