Description
The DIGIFORCE® 9307 monitors processes in
which precisely defined functional relationships between two or more measured quantities
need to be demonstrated. These measured quantities are recorded synchronously during the
manufacturing process or subsequent functional testing to produce a measurement curve, which is
then assessed using graphical and mathematical evaluation techniques. After internal evaluation,
the measurement curve and computed evaluation results are visualized on the color display and
are also output at the external control interfaces. The processes in the controller are
optimized by a powerful real-time operating system to achieve an extremely fast evaluation
cycle: it typically takes just 15 ms to deliver the global OK or NOK evaluation result, which
can then be analyzed by the higher-level controller.
In addition to the traditional evaluation windows with defined entry and exit sides, the
DIGIFORCE® 9307 also offers thresholds,
trapeziums of type X or Y and envelopes as graphical evaluation elements.Individual evaluation
results from the graphical tools can then be combined by mathematical operations to provide even
more analysis flexibility for a huge range of signal curves.
DIGIFORCE® has a wide range of process
control applications, including monitoring processes such as joining, riveting or calking, or
checking torque curves, for instance for hinges or high-quality rotary controls. Even complex
signal/time curves (e.g. pressure curves, leaks etc.) can be monitored using the large choice of
evaluation techniques.
Simultaneous recording of up to two Y variables (Y1 and Y2) with respect to a common X variable
allows many applications to use one DIGIFORCE® controller to monitor two synchronous
processes.
Alternatively, this feature can be used to evaluate an application with three process variables,
for instance the force/displacement curve and associated current consumption of a lifting
electromagnet. While DIGIFORCE® is used in
many automated production areas, it is equally at home in the manual workstation, for instance
to monitor force/displacement when using hand presses for assembly or for random spot-checking
in goods inwards.
