Note
Machine manufacturer
Machine data MD27860 $MC_PROCESSTIMER_MODE is used to switch-in the timer that
can be activated.
The behavior of active time measurements for certain functions (e.g. GOTOS,
override = 0%, active test run feed, program test, ASUB, PROG_EVENT, …) is configured
using machine data MD27850 $MC_PROG_NET_TIMER_MODE and
MD27860 $MC_PROCESSTIMER_MODE.

Note
Residual time for a workpiece
If the same workpieces are produced one after the other, then the timer values:
• Processing time for the last workpiece produced (see $AC_OLD_PROG_NET_TIME)
and
• Current processing time (see $AC_ACT_PROG_NET_TIME)
can be used to determine the remaining residual time for a workpiece.
The residual time is displayed on the operator interface in addition to the current processing
time.
NOTICE
Using STOPRE
The system variables $AC_OLD_PROG_NET_TIME and
$AC_OLD_PROG_NET_TIME_COUNT do not generate any implicit preprocessing stop.
This is uncritical when used in the part program if the value of the system variables comes
from the previous program run. However, if the trigger for the runtime measurement
($AC_PROG_NET_TIME_TRIGGER) is written very frequently and as a result
$AC_OLD_PROG_NET_TIME changes very frequently, then an explicit
STOPRE should be
used in the part program.
General conditions
● Block search
No program runtimes are determined through block searches.
● REPOS
The duration of a REPOS process is added to the current processing time
($AC_ACT_PROG_NET_TIME).
