Workpiece counter

Fu n ctionality
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 counting algorithm.
C o unters
● $ AC_REQUIRED_PARTS
Number of workpieces required (workpiece setpoint)
In this counter you can define the number of workpieces at which the actual workpiece counter $AC_ACTUAL_PARTS is
reset to zero.
The generation of the display alarm 21800 "Workpiece setpoint reached" can be activated via machine data.
● $ AC_TOTAL_PARTS
Total number of workpieces produced (total actual)
The counter specifies the total number of all workpieces produced since the start time.
The counter is set to zero automatically upon every booting of the control system.
● $ AC_ACTUAL_PARTS
Number of actual workpieces (actual)
This counter registers 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.
● $ AC_SPECIAL_PARTS
Number of workpieces specified by the user
This counter allows users to make a workpiece counting in accordance with their own definition. Alarm output can be
defined for the case of identity with $AC_REQUIRED_PARTS (workpiece target). Users must reset the counter
themselves.
