Meaning
Processing time in seconds
The runtime of the path axes (at least one is active) is
measured in all NC programs between NC start and
end of program/NC reset without rapid traverse
active. The measurement is interrupted when a dwell
time is active.
The value is automatically reset to "0" every time the
control powers up with default values.
Actual net runtime of the current NC program in
seconds.
Is automatically reset to "0" when a new NC program
starts.
Net runtime in seconds of the program that has just
be correctly ended with
M30
Changes to $AC_OLD_PROG_NET_TIME
After POWER ON,
$AC_OLD_PROG_NET_TIME_COUNT is at "0".
$AC_OLD_PROG_NET_TIME_COUNT is always
increased if the control has newly written to
$AC_OLD_PROG_NET_TIME.
Trigger for the runtime measurement:
0 Neutral state
The trigger is not active.
1 Exit
Ends the measurement and copies the value
from $AC_ACT_PROG_NET_TIME into
$AC_OLD_PROG_NET_TIME.
$AC_ACT_PROG_NET_TIME is set to "0" and
then continues to run.
2 Start
Starts the measurement and in so doing sets
$AC_ACT_PROG_NET_TIME to "0".
$AC_OLD_PROG_NET_TIME is not changed.
3 Stop
Stops the measurement. Does not change
$AC_OLD_PROG_NET_TIME and keeps
$AC_ACT_PROG_NET_TIME constant until it
resumes
4 Resume
The measurement is resumed, i.e. a
measurement that was previously stopped is
continued. $AC_ACT_PROG_NET_TIME
continues to run. $AC_OLD_PROG_NET_TIME
is not changed.
