Bahavior for NC Stop
The behavior of the function "event-driven program call" for NC-Stop (i.e. NC/PLC interface signal
DB21, ... DBX7.2, 7.3 or 7.4 is set) can be set channel-specific for the triggering event part program end,
operator panel reset and power up with the machine data:
MD20193 $MC_PROG_EVENT_IGN_STOP
In this way, an edge change of the interface signal DB21, ... DBX7.3 (NC-Stop) initiated by the user by activating
the NC Stop key in case of reset or power-up is ignored during the execution of the event-driven user program
and an undesired stop behavior at the machine is prevented.
2 • upon an activation through operator panel reset:
0 is not suppressed.
1 suppressed.
3 • upon an activation through power-up
0 is not suppressed.
1 suppressed.
Note
The system variables $AC_STAT and $AC_PROG are not affected by this function, i.e. in the
running event-driven user program $AC_STAT is set to "active" and $AC_PROG to
"running".
NC/PLC interface signals DB21, ... DBX35.0-7 ("Program status ..." and "Channel status ...")
also remain unaffected.
Bit Value Description
The event-driven user program is:
1 • upon an activation through part program end
0 stopped/prevented at NC stop
1 despite NC Stop been completely processed.
2 • upon an activation through operator panel reset:
0 stopped/prevented at NC stop
1 despite NC Stop been completely processed.
3 • upon an activation through power-up
0 stopped/prevented at NC stop
1 despite NC Stop been completely processed.
Note
A programming of
DELAYFSTON
/
DELAYFSTOF
in the event-driven user program cannot be
provided with the behavior set with MD20193, because the NC Stop can cause an
interruption before the execution of the first command
DELAYFSTON
.
