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
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
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
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.
