Workpiece counter

Function
The "Workpiece counter" function makes available various counters which can be used in
particular internally in the controller to count workpieces.
The counters exist as channel-specific system variables with read and write access in a
range of values from 0 to 999 999 999.
System variable
$AC_REQUIRED_PARTS
$AC_TOTAL_PARTS

Meaning
Number of workpieces to be produced (setpoint number of
workpieces)
In this counter the number of workpieces at which the actual workpiece
count ($AC_ACTUAL_PARTS) will be reset to "0" can be defined.
Total number of completed workpieces (actual workpiece total)
This counter specifies the total number of all workpieces produced
since the start time. The value is only automatically reset to "0" when
the controller powers up with default values.
