4 Sensor Configuration
4.1 Configuration
Shows the parameters that affect the sensor/controller (see Fig. 3 ILD1700
Sensor Configuration).
Fig. 3 ILD1700 Sensor Configuration
4.1.1 Connection Setting
The COM port the ILD1700 controller is connected to. Supported port
numbers are COM1 to COM16. The sensor uses a RS422 to USB interface that
is mapped to a COM port, which can be viewed in the device manager. For
the exact port number see the device called ‘USB to Serial Port’. On a
German OS, that item is located in ‘Anschlüsse (COM und LPT)’.
4.1.1.1 Baud Rate
The baud rate, which the controller is currently using to transfer parameters
and data.
ILD1700 Tool
___________________________________________________________________________
Micro-Epsilon Page 8
4.1.1.2 COM Port
The port that should be used to communicate with. Available ports are
COM1 to COM16. The device manager shows which ports are installed and
eventually which devices are using them.
4.1.2 Sensor Parameters
4.1.2.1 Baud Rate
This parameter determines the communication baud rate of the controller.
When writing the parameters to the controller (see button ‘Write Configuration
To Sensor’) first all others parameters are written and at last, the baud rate is
changed. A different baud rate requires disconnecting and reconnecting to
the controller, which is executed automatically. All subsequent
communication will use that new baud rate.
4.1.2.2 Measurement Frequency
Determines the maximal possible exposure time (e.g. at 2.5kHz the max.
exposure time is 0.4 ms). Available sampling rates are: 2.5kHz, 1.25kHz,
625Hz, and 312.5Hz. However, these sampling rates do not always match
the data rate, because the baud rate, the transfer mode and the
synchronization do have some effect on it. The effective data rate can be
viewed in the section ‘Sensor Information’ after executing the ‘Read Sensor
Info’ button (see Sensor Information). The sensor manual contains a table that
shows more on that.
4.1.2.3 Output Type
The mode ‘RS422’ activates the digital data output. The items ‘4..20mA’ and
‘0..10V’ activate the analog data output (pin 13). The limit outputs (pin 7 and
8) work in analog mode only.
4.1.2.4 Synchronization
Determines the synchronization method with other ILD1700 sensors. The
modes ‘Slave’ and ‘Master Sync. Alt.’ affect the data rate. See the sensor
manual for more on that.
4.1.2.5 Average Type
Available averaging modes are: Recursive, Moving, Median.
4.1.2.6 Average Number
The higher the averaging number the smoother the signal will look, but a high
averaging number may impair the measured signal.
4.1.3 Calibration
Displays whether the sensor was mastered or set to mid-point. Both actions
can be executed only by the ‘Zero’ button on the sensor.
Mid-point: When the sensor is in Error Mode the Zero button on the housing
commands the sensor to use the current distance as mid-point (5V or 12mA)
of the measurement range which only affects the analog data output.
(This works similar to the ‘Set Zero’ function in the included Data Acquisition
program, which just calculates an offset on the digital measurement values.)
Mastering: When the sensor is in Switch Mode (also called Limit Mode) the
Zero button commands the sensor to set the currently measured value to the
Master Value. The master value can be set in the ‘Sensor Configuration’
ILD1700 Tool
___________________________________________________________________________
Micro-Epsilon Page 9
program, see section ‘Switch Output’ parameter ‘Master Value’. This has an
effect on the analog and digital data outputs.
Mastering works much as common calibration does. A reference target of
known distance is measured by the sensor (that distance is sent to the sensor
as parameter ‘Master Value’). Next triggering the Zero button on the sensor
calibrates the sensor distance for that reference target.
4.1.4 Additional Parameters
4.1.4.1 Error Handling
‘Hold Last Valid Value’ makes the sensor put out the last measured value after
the sensor ‘looses’ its target. To loose a target means no valid target is in
range or the sensor cannot see the laser point.
‘Set Error Value’ commands the sensor to put out an error value as indication
that no valid target is recognized.
4.1.4.2 Transfer Mode
The ‘Binary’ mode is faster and eventually delivers more measurement
values, especially when connecting with slower baud rates. Therefore, the
included data acquisition program switches the sensor into binary mode
when started.
The ‘ASCII’ mode may be more suitable when using the HyperTerminal or
other diagnostic tools to communicate with the sensor.
4.1.4.3 Laser
Turns the laser diode on or off.
4.1.4.4 Sensor Keys
Disables/enables the buttons on the sensor housing to prevent unintended
changes.
4.1.5 Switch Output – Properties
Except for the ‘Master Value’, this section is useful for the analog output
modes only.
4.1.5.1 Monitoring
Sets the sensor and the limit/error outputs F1 and F2 into limit or error mode.
Error Mode: Indicates an error on either error output F1 or F2 (pin7 or pin8)
when no valid target is recognized. (The parameter Limit Assignment
determines which).
Limit Mode: Uses the limit outputs F1 and F2 to indicate limit violations
(which is especially useful for production surveillance). In case of an error,
both limit outputs are activated.
4.1.5.2 Limit Assignment
Either assigns the limit output F1 or F2 to the Upper Limit. The other of the two
indicates a limit violation of the Lower Limit.
4.1.5.3 Upper Limit
A threshold for the analog surveillance of the measurement values.
Determines the furthest distance from the sensor head a measured object
may have, before a limit violation error is indicated on the output F2 (or F1 if
the parameter Limit Assignment is set to that).
ILD1700 Tool
___________________________________________________________________________
Micro-Epsilon Page 10
4.1.5.4 Upper Hysteresis
If the measurement value falls below this threshold the limit output F2 (or F1)
is reset to normal state; i.e. no longer indicates a limit violation.
4.1.5.5 Master Value
Value that is used by the sensor if the Zero button on the sensor housing is
pressed. The sensor then uses its current measurement value as reference
point, sets it to zero, and adds the master value. This method can be used to
calibrate the senor position by using a reference target of known
distance/thickness (see 4.1.3).
4.1.5.6 Lower Hysteresis
If the measurement value rises again above this threshold the limit output F1
(or F2) is reset to normal state; i.e. no longer indicates a lower limit violation.
4.1.5.7 Lower Limit
A threshold for the analog surveillance of the measurement. The closest
distance a measured object may have from the sensor head before an error
is indicated on the output F1 (or F2, which depends on the parameter Limit
Assignment).
4.1.6 Sensor Information
Displays some general information about the sensor.
4.1.6.1 Sensor Range
Measurement range of the sensor.
4.1.6.2 Read Sensor Info
This button requests the sensor to put out its parameters, e.g.: firmware
version, serial number, article number and some additional information.
4.1.7 Configuration Management
This section supports the storage of parameter sets in files. Can be used to
build a database of presets for different tasks, back up controller settings, or
simply to transfer setting from one sensor to another.
The edit field shows the file name of the most recently accessed parameter
set.
Save to file…: Opens a ‘save as’ dialog to browse to a storage destination
and select or enter a filename.
Load from file…: Shows a dialog to browse to a stored file.
4.1.8 Transfer Configuration
Load Configuration From Sensor:
Reads the current settings from the sensor, e.g. sample rate, switch mode…
and shows them in the ILD1700 Sensor Configuration dialog.
Write Configuration To Sensor:
The parameters of the sensor can be either set up by using the enabled
input fields or loaded from a configuration file (see 4.1.7). This button writes
these parameters to the sensor/controller.

4.1.9 Sensor Fallback
Reset To Factory Settings: Overwrites the parameters stored in the sensor with
the default parameters. For example sets the baud rate to 115200.
Reboot Sensor: Keeps the parameters but restarts the sensor as if it was
turned off and on again.

5 Data Acquisition Program
This program can be used to acquire, evaluate and store data from an
ILD1700 sensor.
Fig. 4 Data Acquisition
5.1 Configuration
5.1.1 Connection Settings
This measurement program requires a COM port with settings: 115200, 8, n,
1.
5.1.1.1 COM
Number of the COM port the ILD1700 sensor is connected to (see 4.1.1).
5.1.1.2 Block size
Determines the number of values to read at once. A smaller block size
reduces the reaction time (here: display refresh) but increases the system
load. The number of updates per second = Sample_rate/Block_size. If the
display is delayed or measurement values get lost, a higher block size is
required.
5.1.1.3 Measurement Frequency
Displays the number of samples that are taken per second.
5.1.1.4 Sensor Range
Measurement range of the connected sensor.
ILD1700 Tool

Micro-Epsilon Page 13
5.1.2 Y-Axis Scaling Properties
This mode automatically adjusts the y-scale of the display to zoom in on the
measured values as close as possible.
In manual mode the value range can be set by entering the min. and max.
limits of the y-axis.
5.1.2.1 Flip Y axis
Turns the measured signal upside down. Can be used for example to display
the surface of a measurement target.
5.1.2.2 Y-Scaling Type
The scaling of the y-axis can be set to one of the following methods.
• Manual Y range:
Enables the edit fields for the user can enter the upper and lower limit
of the y–axis.
• Autoscale Y range:
The program searches the smallest and greatest value in the visible x-
range and sets the y-limits to those values.
• Y center on data:
This scaling mode requires the parameter Range(mm), here called
Y_range.
The program calculates the average of the measurement values in
the visible x-range. Then it sets the upper limit of the y-axis to
average+Y_range and the lower limit to average- Y_range.
5.1.2.3 Range (mm)
This parameter determines the area of interest around the mean value of the
measurement signal.
5.2 Data Acquisition
The purpose of this page is to acquire data, only. It does not change any of
the sensor’s parameters. There is one exception: it sets the transfer mode
from ASCII to binary.
This data acquisition module requires a baud rate of 115200. Also the laser
diode must be turned on.
5.2.1 Measurement Properties
5.2.1.1 Data Acquisition
The button shows ‘Start DAQ’ if no connection to a sensor was established. To
connect to a sensor and to start the measurement press the button once. If
the connection was successful, the button shows ‘Stop DAQ’. Another click on
the button stops the measurement.
5.2.1.2 Hold last valid value
If no valid target can be recognized the last valid value is kept and put out,
otherwise an error value is put out to indicate that the sensor has ‘lost’ its
target.
5.2.2 AutoZero Properties
This section offers a software distance calibration of the sensor position.
ILD1700 Tool
___________________________________________________________________________
Micro-Epsilon Page 14
5.2.2.1 Set Zero
Takes the current measurement value as reference point and sets it to zero;
i.e. subtracts the value that was measured as the button was pressed from
the subsequent measurements.
5.2.2.2 Reset
Undoes the set zero operation and shows the value the sensor puts out.
5.3 Data Storage
5.3.1 Data Export Properties
The name in the storage file is separated into two edit fields: The upper field
shows the path, the lower the name of the file. It is recommended to use the
browse button to select/create a file, which assures that the path is valid and
accessible.
5.3.1.1 Store displayed samples
After an object was measured, the measurement values can be zoomed
and moved to the interesting part. It is important that the interesting values
are displayed in the plot graph, because only the displayed values are
stored when using the button ‘Store displayed samples’.
5.4 Distance View
This view displays the currently acquired or buffered measurement values. It
also shows the thresholds for the limit surveillance (switch mode).
5.4.1 Distance
In live mode this field shows the latest measurement value, in freeze mode it
shows the rightmost value.
5.4.2 Statistics
The statistical values are calculated on the measurement values currently
displayed in the plot graph.
5.4.2.1 Mean
Average over all displayed samples.
5.4.2.2 Min
Shows the lowest measurement value within the visible x-range.
5.4.2.3 Max
Shows the highest measurement value within the visible x-range.
5.4.2.4 P-P
Peak to peak value. Difference between minimum and maximum value.
5.4.3 Limit Output Properties
The limit mode of the sensor is available for the analog outputs, only.
Therefore, this application contains a limit simulation, which can be used to
adjust the sensor’s limit properties. All parameters set here will be copied to
ILD1700 Tool
___________________________________________________________________________
Micro-Epsilon Page 15
the configuration sub program, where they can be stored and transferred to
the sensor.
5.4.3.1 Activate switch sim.
Enables the input elements for the switch limits and shows the two LEDs,
which indicate the state of the limit outputs F1 and F2.
5.4.3.2 Upper limit
All limits are displayed in mm. This limit is displayed in the plot graph as a red
line. All measurement values above this threshold are drawn red to indicate
a limit violation. This limit violation is also shown by the red color of the upper
LED. This LED indicates the state of the upper limit output.
5.4.3.3 Upper hysteresis
If the measurement value falls below this threshold, the upper LED is set to
green again. This threshold is displayed in orange.
5.4.3.4 Master value
Although this value is not used for the limit monitoring, but for calibration
purposes, it is placed here.
If this value (in the controller) is set to zero, then the controller’s Zero button
does the equivalent as the ‘Set Zero’ button in this application does. This
value is displayed in the plot graph as blue line.
5.4.3.5 Lower hysteresis
If the measurement value rises above this threshold, the lower LED is set to
green. This threshold is displayed in orange.
5.4.3.6 Lower limit
If the measurement value falls below this limit the lower LED turns red. This
threshold is displayed in the plot graph as a red line.
5.4.4 Freeze Mode Navigation
This application continuously acquires data as long as the button ‘Data
acquisition’ is checked. The last 60 seconds since the ‘DAQ Start’ or ‘Clear
Buffer’ are stored in an internal buffer and can be examined any time.
5.4.4.1 Position
This scrollbar can be used to navigate through the internal data buffer.
5.4.4.2 Zoom +
Selects a smaller section of the x-axis; i.e. closes in on the data. Can be used
to minimize the number of values stored in a file.
5.4.4.3 Zoom –
The opposite of zoom+. Shows more measurement values at once.
5.4.4.4 Show All
Displays all values of the internal data buffer at once.
5.4.4.5 Freeze
As long as this button is unchecked, the display is in live mode, that is, the
currently acquired samples are charted on the plot display. If you check the
‘Freeze’ button, the application creates a copy of the internal data buffer.
This copy can be zoomed and scrolled through to take a closer look at the
measurement. To end the freeze mode uncheck the ‘Freeze’ button. That
action removes the copy of the data buffer and switches into live mode
again.
ILD1700 Tool
___________________________________________________________________________
Micro-Epsilon Page 16
5.4.4.6 Clear buffer
This button can be used to empty all data buffers and switch into live mode.
5.4.5 F1/F2 Upper limit
This LED displays the state of the output for the upper limit. A red LED
indicates the upper limit is violated and the corresponding limit output is set
to high. A green LED shows the limit output is set to low.
5.4.6 F2/F1 Lower limit
The same as the upper limit except that it indicates when the lower limit is
violated.
