Application
The DIGIFORCE®9307 monitors processes in which precisely
dened functional relationships between two or more mea-
sured quantities need to be demonstrated. These measured
quantities are recorded synchronously during the manufac-
turing process or subsequent functional testing to produce a
measurement curve, which is then assessed using graphical
and mathematical evaluation techniques. After internal evalua-
tion, 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 dened
entry and exit sides, the DIGIFORCE® 9307 also offers thresh-
olds, 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 opera-
tions to provide even more analysis exibility for a huge range
of signal curves.
DIGIFORCE® has a wide range of process control applications,
including monitoring processes such as joining, riveting or
caulking, 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 appli-
cation 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/displace-
ment when using hand presses for assembly or for random
spot-checking in goods inwards.

Block diagram
Measurement data acquisition
With an active measurement, which can be triggered by
different events, the synchronously measured quantities X,Y1
and optionally Y2 are saved in the measurement data memory.
Real-time signals can indicate whether measurements are
exceeding set signal levels while the measurement is still in
progress. The evaluation phase follows immediately after the
measurement. In this phase, DIGIFORCE®checks whether the
recorded measurement curve(s) satisfy the stored graphical
and mathematical evaluation criteria. If any of these criteria has
been infringed, the measurement is classied as BAD (NOK),
otherwise it is rated as GOOD (OK). Once this evaluation is
complete, the measurement curve, the global OK or NOK result
and numerous process-related values are displayed in a suite of
measurement windows and updated at the Fieldbus interface.
The processing steps of the evaluation phase, which nishes
when the equipment is ready for the next measurement, have
been optimized so that even dynamic manufacturing processes
can be monitored.

measurement curve. Shows a curve containing a
forward and return section and detailed evaluation using
windows, envelopes, thresholds and mathematical
operations.
Evaluation of a measurement curve
As a universal evaluation tool for a vast range of curve shapes,
the DIGIFORCE® 9307 provides congurable evaluation ele-
ments, which can be used to classify a measurement curve as
OK or NOK. In addition to the traditional evaluation windows
with dened entry and exit sides, the DIGIFORCE®9307 also
uses 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 mathemati-
cal operations to provide even more analysis exibility for a
range of signal curves. The graphical evaluation elements can
be congured both numerically and graphically in setup mode
using one or more recorded measurement curves. They can be
used in any combination, even overlapping in an X/Y graph.
Window evaluation
Symbol
Max. number: 10
The Window evaluation element tests whether the curve has
passed through the dened entry side and exit side in the
window area. The user can congure these entry/exit sides
as required, and can even set multiple input/output sides.
A live signal can be assigned to up to two windows, which
is enabled immediately during recording if any infringement
occurs. It is also possible to dene windows of type NOT (no
entry/exit) or BLOCK (curve ends inside the window) by suitable
conguration of the entry/exit sides. This evaluation element
also calculates the values listed below, which can optionally
be displayed and also input to user-denable mathematical
functions for further processing and evaluation:
► Entry and exit coordinates (measurement pairs)
► Local minimum/maximum
► Absolute minimum/maximum
► Mean value YMean
► Integral (area below curve to YMIN limit inside window)
► Curve gradient
► Inexion point

Trapezium evaluation element
Symbol
Max. number: 4
The DIGIFORCE® 9307 offers two different types of trapezium:
the type-X trapezium window with xed XMIN, XMAX limits and
type-Y trapezium with xed YMIN, YMAX limits. The trapezium
evaluation element tests whether the curve has passed through
the dened entry and exit sides; only one entry side can be con-
gured for this element. The entry/exit values are calculated.
Threshold evaluation element
Symbol
Max. number: 4
The threshold evaluation element can be used to calculate
and monitor where the measurement curve passes through
a dened X-value or Y-value. The user can choose between
threshold type X or Y. Threshold type Y provides the following
extra results:
► Local minimum/maximum
► Absolute minimum/maximum
► Mean value YMean
► Integral (area between curve and X-axis in the threshold
region XMIN to XMAX)
► Curve gradient
► Inexion point
Envelope evaluation element
Symbol
Max. number: 2
The DIGIFORCE® 9307 can use one or more measurement
curves to generate up to two envelopes. The user can then
customize a generated envelope in the X-domain, and also
set tolerances for the Y-domain. For a measurement curve
comprising a forward and return curve section, the envelope
cannot lie over the turning point.
When subsequently monitoring a measurement in measure-
ment mode, DIGIFORCE® tests whether the measurement
curve lies within the dened envelope band i.e. is classied
OK, or whether the curve passes outside the valid envelope
and hence must be classied NOK.
Rotary switch evaluation element
Symbol
Max. number: 2
The Rotary switch evaluation element enables haptic testing of
rotary switches and rotary or rotating controls comprising up to
32 control positions. This evaluation tests whether the number
and level of force maxima and minima satisfy the saved criteria.
In addition, the angular distance and Y-mean value of the
extreme values will be monitored.
Mathematical operation
Symbol
Max. number: 10 of which 6 can be evaluation
Specic measurement curve variables and results from the
graphical evaluation elements can be combined using basic
mathematical operators (+, -, x, ÷) and evaluated. A result can
be processed further in a subsequent operation. The evalu-
ation is fed into the global evaluation result. The results of a
mathematical operation can be displayed in a measurement
window and retrieved via the Fieldbus and/or communica-
tion interfaces.
A + B/2
Flexible process integration
The DIGIFORCE® 9307 has the versatility to integrate
into practically all process environments. A huge number
of detailed requirements can be implemented using the
numerous I/Os (23 inputs / 31 outputs), some of which can
be assigned user-dened functions. A measurement can be
started and terminated at variable times by different internal
and external events.
Sampling and recording measurement signals
Signals can be sampled as a combination of time interval (∆t),
X-interval and Y-interval (∆X, ∆Y) to provide a exible yet also
compressed measurement recording. Curve areas containing
a constant or steadily changing signal can be reproduced
with just a few stored measurement points, while steep signal
slopes or alternating waveforms require many points.
Start/Stop conditions for measurement recording
The DIGIFORCE® 9307 lets the user dene independent
start/stop logic.
Start conditions: Ext. control signal, measurement above or
below a denable X-value or Y-value.
Stop conditions: Ext. control signal, measurement above
or below a denable X-value or Y-value, timeout, denable
number of recorded measurements reached.
Recording and evaluating two synchronous processes
Two signal curves Y1 and Y2 can be recorded with respect
to a common X-channel and evaluated in one measurement
phase. For the evaluation, the user assigns the required
graphical evaluation elements to each graph, and the evalu-
ation is performed independently using separate process
signals (OK-Y1/2). Alternatively, it is possible to monitor an
application that has three process variables.
Limit monitoring in real time
S1 ... S4 The user is able to assign the switching
signals S1 ... S4 to the three measurement
channels X, Y1/2 as required, and can set
their polarity. The associated PLC I/Os
and Fieldbus signals are updated both in
standby mode and also in real time during
the measurement cycle (response time
< 10 ms).
NOK ... ONLINE1/2 Up to two live signals (NOK-ONLINE1/2)
can be used if the curve does not pass
through the permitted region of the win-
dow evaluation element. This allows pre-
emptive termination of a joining process
in ultra-quick time if the two components
get intertwined, protecting parts, tools or
even the entire system from damage.

Process data
The DIGIFORCE® 9307 visualizes a comprehensive set of pro-
cess data during measurement mode and automatic produc-
tion mode. All relevant process data can be transferred to the
controller or PC environment immediately after a measurement.
The user can switch between the following process windows:
► M1-1/2 Graph of Y1(X) or Y2(X) measurement curve
► M1-3 Shared display of Y1/2(X) curves
► M2-1/2 General display of Y1(X) or Y2(X) curves
► M3 Full-screen PASS/FAIL or smiley
► M4 Entry/exit data for evaluation elements
► M5 List of user-specic process values
(up to 24 values)
► M6 Statistics on all graphical evaluation
elements (trend/histogram)
► M7
Job sheet containing process, worker and parts
data for transfer to process-data acquisition
Each process window displays the global header containing
information on the selected measurement program, the asso-
ciated part quantities and NOK gures, and the global OK/NOK
evaluation. The status eld on the right shows the evaluation
elements that are active in the measurement program and their
individual results.
Sensor conguration and adjustment
The user can choose which physical channels A...F to assign
to the measurement graphs (X, Y1/2 coordinates) and set the
graph scale. This gives the user the freedom, for instance, to
use a preferred mounting for a displacement sensor, and then
set the scale to display/evaluate a decreasing or increasing,
positive or negative displacement. There are several options
for adjustment: adopting the sensor specication from the
burster TEDS electronic data sheet, manual input from the
sensor certicate data, or using the teach-in process.

32/128 measurement programs
The DIGIFORCE® 9307 comes with the capability to manage up
to 32 measurement programs, which can be rapidly selected
via I/O, Fieldbus or keypad. Each measurement program con-
tains the full conguration of sensors, measurement procedure
and evaluations. The PC software DigiControl can be used to
download alternative DIGIFORCE® 9307 rmware, which has
the capability to handle up to 128 measurement programs.
This rmware re-allocates the internal memory so that up to
400 measurement pairs/triplets can be recorded.
The intelligent sampling tool, with its facility to combine vari-
ables (∆t, ∆X and ∆Y), ensures that these 400 value pairs are
normally sufcient to reproduce and evaluate a measurement
curve.
Internal measurement curve memory
In graphical setup mode, one or more imported measurement
curves can be used to congure the evaluation elements. This
is still possible even if the process requires a change in mea-
surement program back at the setup stage. Up to ten measure-
ment curves can be saved in each measurement program as a
curve array, which then provides the basis for the evaluations
to be dened. In measurement mode, this memory acts as a
ring buffer, where the remaining 50 measurement curves are
stored. The DigiControl PC software can be used to retrieve
and analyze these measurements.
User-denable function keys
The function keys F1...F4 below the display can be assigned to
various functions as required. The following functions are avail-
able for selection for example: browse measurement screens,
tare, start/stop measurement, change program, conrm OK/
NOK evaluations, sensor test.
burster TEDS*
DIGIFORCE® 9307 uses burster TEDS (Transducer Electronic
Data Sheet) for automatic identication of sensors connected
to channels A and B. The instrument reads the relevant sen-
sor data from an EEPROM chip in the sensor connector and
uses this data to perform the necessary channel conguration
automatically. The memory chip in the sensor connector is
programmed as part of a service provided when the sensor
is rst ordered or subsequently calibrated. The burster TEDS
feature is only available for sensors that have a permanently
tted connecting lead.
* available for SN 530000 onwards (Q2/2018)
The basic version of this software, available free of charge,
offers full device conguration, data backups, and export and
display of measurement curves including all evaluation re-
sults. An especially convenient feature is the facility to dene
graphical evaluation elements such as envelopes, windows,
trapeziums and thresholds from a set of curves measured for
master or reference parts. Alternatively, pre-archived mea-
surements can also be analyzed to create new evaluations.
In addition to these basic functions, the Plus version
(9307-P100) of the DigiControl PC software provides an auto-
matic production mode, allowing log measurement data dur-
ing production with clear parts referencing, for example. The
resultant measurement reports are not only available in the
internal program format, but can also be ported into the fol-
lowing formats: ASCII raw data, EXCEL, PDF Print and SQL.
DigiControl PC software for DIGIFORCE® 9307, 9310 and 9311
Even for synchronous processes involving large amounts of
data, logging of measurement data is optimized to achieve an
ultra-short cycle time. For more complex tasks, the software
also supports an additional remote interface, for instance for
loading a new device conguration or transferring compo-
nent names for measurement-data logging.
Porting DIGIFORCE®9306 to DIGIFORCE®9307
DigiControl can be used to create a DIGIFORCE®9307 de-
vice conguration from a DIGIFORCE® 9306 backup le.
This is done by importing the sensor and evaluation settings
and selecting as close a conguration as possible for the
DIGIFORCE® 9307. Then just a few minor nal adjustments
and settings are needed to resume production under process
control.
