Workpiece counter

Functionality
The "Workpiece counter" function provides counters for counting workpieces.
These counters exist as system variables with write and read access from the program or via
operator input (observe the protection level for writing!).
Machine data can be used to control counter activation, counter reset timing and the count-
ing algorithm.
Meters
● $AC_REQUIRED_PARTS- Number of required workpieces ( workpiece target )
● $AC_TOTAL_PARTS- Total number of workpieces actually produced ( total actual )
● $AC_ACTUAL_PARTS- Number of current workpieces (current actual)

The number of workpieces at which the number of current workpieces
$AC_ACTUAL_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.
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.
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.
