A REPOS instruction must have been programmed at the end of the interrupt routine if return
positioning to the point of interruption is required, e.g.
N104 REPOSL M17

Interrupt routine with REPOSA

If an interrupt routine with REPOSA triggered by the PLC (block FC9) "interrupted" in channel
status in program operation is completed, then the following sequence is typical:
1. Before the re-approach to the contour, the controller stops and goes to program status
"Stopped". The following NC/PLC-interface signal is set:
DB21, ... DBX318.0 (ASUB is stopped)
2. The operator presses the START key. Thereupon, the signal DB21, ... DBX318.0 is reset
and the re-approach motion starts.
3. 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.
Note
The NC/PLC-interface signal DB21, ... DBX318.0 (ASUB is stopped) is available only for
the following case: Interrupt "interrupted" in program operation in the channel status.
Note
In case of interrupt routines that close without REPOS, the signals "Asub-Done" and
DB21, ... DBX318.0 (ASUB is stopped) occur at the same time.
