Programming example
N10 IF $AC_CUTTING_TIME>=R10 GOTOF WZZEIT ; Tool action time limit value
...
N80 WZZEIT:
N90 MSG(“Tool action time: Limit value reached”)
N100 M0
Display
The contents of the active system variables is displayed on the screen under <OFFSET PA-
RAM> <Setting data> <Timers/counters>:
Total runtime = $AC_OPERATING_TIME
Time of program execution = $AC_CYCLE_TIME
Time of feedrate action = $AC_CUTTING_TIME
Time since cold start = $AN_SETUP_TIME
Time since warm restart = $AN_POWERON_TIME
“Part count” is visible in addition in the AUTOMATIC mode in the “Position” operating area in
the information line.
8.10.2 Workpiece counter
Functionality
The “Workpiece counter” function provides counters which can be used for counting of work-
pieces.
These counters exist as system variables with read-write access from the program or
through operation (observe protection level for writing!).
The counter activation, the time of zeroing and the counter algorithm can be influenced via
machine data.
Counters
S $AC_REQUIRED_PARTS – Number of required workpieces ( workpiece target )
The number of workpieces at which the number of current workpieces $AC_AC-
TUAL_PARTS is set to zero can be defined in this counter.
The generation of the display alarm 21800 “Workpiece setpoint reached” can be activated
via machine data.
S $AC_TOTAL_PARTS – Total number of workpieces actually produced
( total actual )
The counter indicates the total number of workpieces produced since the starting time.
The counter is automatically set to zero upon every booting of the control system.
S $AC_ACTUAL_PARTS – Number of current workpieces (current actual)
This counter records the number of all workpieces produced since the starting time.
When the workpiece setpoint is reached ( $AC_REQUIRED_PARTS, value greater than
zero), the counter is automatically zeroed.
