$AN_SETUP_TIME
$AN_POWERON_TIME
The following three timers are defined as
channel-specific system variables and can be
activated via machine data.
$AC_OPERATING_TIME
$AC_CYCLE_TIME
$AC_CUTTING_TIME
$MC_RUNTIMER_MODE
All timers are reset with default values when the
control is powered up, and can be read independent
of their activation.
Programming example
1. Activate runtime measurement for the active NC
program; no measurement with active dry run
feedrate and program testing:
$MC_PROCESSTIMER_MODE
2. Activate measurement for the tool operating time;
measurement also with active dry run feedrate and
program testing:
$MC_PROCESSTIMER_MODE= 'H34'
3. Activate measurement for the total runtime and
tool operating time; measurement also during
program testing:
$MC_PROCESSTIMER_MODE= 'H25'

13.8.2 Workpiece counter

Function
The "workpiece counter" function can be used to
prepare counters, e.g. for internal counting of
workpieces on the control. These counters exist as
channel-specific system variables with read and write
access within a value range from 0 to 999 999 999.
