Behavior when the read-in disable is set
Via the following channel-specific machine data it can be set, whether the activated ASUB are processed without
interruption despite a set read-in disable (DB21, ... DBX6.1 = 1), or whether the read-in disable is to be made
active:
MD20107 $MC_PROG_EVENT_IGN_INHIBIT
Programming
The event that has started this ASUB can be determined by scanning the system variable $P_PROG_EVENT. In
case of an automatic activation after a block search $P_PROG_EVENT returns the value "5".
Sequence
Sequence of automatic start of an ASUB after a block search
1. Start block search (with/without calculation, at contour, at endofblock point).
2. Stop after "Search target found".
3. NC Start for output of action blocks.
4. Last action block is activated.
5. Automatic start of /_N_CMA_DIR/_N_PROG_EVENT_SPF (default) as an ASUB.
6. The NC will stop after changing the last ASUB block (
REPOSA
command) and the following NC/PLC interface
signal is set:
DB21, ... DBX32.6 (last action block active)
The alarm 10208 "Enter NC-start for program continuation" is generated.

Note
If bit 0 is set to "1" in MD11450 $MN_SEARCH_RUN_MODE, then the alarm 10208 is
generated only when the PLC requests this by setting the following NC/PLC interface
signal:
DB21, ... DBX1.6 (PLC action complete)
