1 General information

1.1 Concerning the contents of this document

This manual contains information about the installation and commissioning of Baumer PosCon OXH7 sensors
with TCP/IP interface.
It is a supplement to the mounting instructions supplied with each sensor.

1.1 Intended use

The Baumer PosCon OXH7 sensor measures heights of objects. It was especially developed for easy
handling, flexible use, and precise measurement.

1.1.1 Functional principle of triangulation

Read these operating instructions carefully and follow the safety instructions!

The sensor works on the laser triangulation principle.
By means of special optics, a laser beam is enlarged
into a line and projected to the surface of the object to
be measured. Using the multi-lens system, the
reflected light from this laser line is projected onto a
matrix. From this matrix image, a controller calculates
the distance to every individual measuring point.
The measuring value is calculated in accordance with
the selected function. Thanks to the new Baumer
technology, the object height is always output
correctly, independent of the object's position in the
measuring field.

2.1 Sensor reference levels

To ensure that the sensor is easy to align during installation, reference levels have been defined. The laser
beam of the sensor runs parallel (//) to level R3 and is at a right angle to levels R1 and R2. Levels R1, R2, and
R3 serve as a reference for sensor alignment during installation. The "Left" and "Right" alignment must also
be observed.

Reference surface

2.4 Alignment

To achieve as reliable and exact measurement values as possible, the following hints and tips for mounting
should be followed.

2.4.1 The reference surface

If the height of the object is to be measured from a specific surface or if the sensor is to be mounted at an
angle of up to ±30°, then the reference surface must be teached using the Flex Mount function.

The following points must be satisfied for teaching the reference surface:

• The reference surface must be within the measuring range of the sensor (Sdc-Sde)

• The sensor may be inclined at a maximum angle of ±30° to the reference surface

• The "maximum unevenness of the reference surface"1 must not exceed the maximum value

• The length of the reference surface must not be less than the "minimum reference surface length"1

value

NOTE

The reference surface…

2.4.2 Angled installation (Flex Mount)

The sensor can be installed at an inclination of up to ±30° to the reference surface for the height function. This
is particularly useful when space conditions do not allow any other installation option. See chapter Flex Mount.
After activation of Flex Mount, the sensor axis is no longer relevant. The measurement coordinate system is
now represented by the M and K axes. The height is now measured in the M direction.

Reference point with inclined installation

2.4.2.1

In the case of angled installation, the reference point (0 mm) of the K axis shifts out of the center of the field of
view or the red visible laser line. Due to inclination of the sensor, the two field of view sections, "Width of field
of view left" and "Width of field of view right", are no longer equal in size.

NOTE

This fact is relevant where the position of the
reference point plays a role, e.g., with the Field of
View function. Left Limit and Right Limit are
measured from this point.

2.5.3 Initial setup of the Ethernet interface on the computer

Assigning an IP address

2.5.3.1

To use the device in your network, you must assign a unique IP address to the device.

1. If you have a DHCP server integrated into your network, the IP address is requested from this server.
No additional manual actions are necessary on your part.

2. If a valid IP address cannot be obtained within 15 seconds, the static IP address is used. When the
device is delivered, this is IP address 192.168.0.250 (subnet mask: 255.255.255.0).

NOTE

To avoid network malfunctions, ensure that each IP address is unique within the network
and has not already been assigned.

Now, link your PC into the same network as the device. If your network does not have a DHCP server, you
may have to adapt the IP address of your PC. With Microsoft® Windows® 7, proceed as follows:

1. Open: Start menu

→ Control Panel → Network and Internet (View network status and tasks) →

Change adapter settings

2. Select your network (e.g., "Local Area Connection") and then the "Properties" entry in the context
menu.

3. Select the "Internet Protocol Version 4 (TCP/IPv4)" entry in the list of elements and then click the
Properties button below the selection list. The following dialog box opens:

Activate the Use the following IP address option and select an address in the range 192.168.0.1-

192.168.0.254 that has not yet been used for the IP address. Enter 255.255.255.0 for the subnet mask
and confirm these settings.

Identifying an unknown sensor IP address

2.5.3.2

If you do not know the IP address of the sensor, either because it was assigned via DHCP or the information
about the static IP address is no longer available, you can query the IP address in the following way:

1. Open a Windows prompt

2. Execute the command ping OXH7-[identifier].local. Replace [identifier] either with
the eight-digit order number or the MAC address indicated on the sensor. Example: ping OXH7-

12345678.local or ping OXH7-11-22-33-44-55-66.local

3. Read the IP address (here: 192.168.0.250) from the command output:

Ping is executed for OXH7-12345678.local [192.168.0.250] with 32 bytes of
data:

If you do not gain access to the sensor when you specify this IP address, change the IP configuration of your
PC as follows:

1. Enter an IP address that comes either directly before or after the sensor IP address.

2. Enter 255.255.255.0 as the subnet mask.

3. Confirm the setting.

3 Configuration via the web interface

3.1 The web interface

The device includes an integrated web server which makes available a graphical user interface (GUI). This
enables configuration and evaluation of the data (e.g., of machine control) directly via the browser.

3.1.1 Supported browsers

Due to differences in browser technology, there may be some differences in appearance between browsers
and browser versions or even incompatibilities with the device. In our experience, these incompatibilities
increase with the age of the browser due to a lack of standardization. We cannot test all browsers and their
various releases, so untested browsers may also function with the device.

Supported browsers are Firefox 59 and Chrome 65.

3.1.2 Connecting to the web interface

1. Launch a supported browser

2. Enter the IP address of the sensor in the address line

NOTE

The default IP address is 192.168.0.250

Standard deviation

The standard deviation is a term from the field of statistics or stochastics and is given in σ (sigma). With the
standard deviation it is possible to determine how great the dispersion of values around a mean value is.
Broadly speaking, the standard deviation is the average distance of all measured expressions of a
characteristic from the mean value.
The standard deviation is only useful if you consider measurement values which should actually be identical
but which vary. For the sensor, this means that an even surface is observed vertically (or with active Flex
Mount). The standard deviation is then a measure for the unevenness of the surface. All measuring points
within the preset field of view are taken into consideration.

en_BA_OXH7_PosCon_TCP_IP.docx 24/98 Baumer Electric AG
Friday, June 15, 2018 12:44:11 PM/tof V1.0 ANW_81184815 Frauenfeld, Switzerland

Remember

• The standard deviation is a measure for the dispersion of the height values of all measured profile
points in mm.

• It can only be used on a plane that is either vertical with respect to the sensor or is parallel to the Flex
Mount reference.

• The plane must cover the entire field of view in the X direction.

Example

This is a profile of 190 points on an even surface as recorded by the sensor before evaluation (height in mm).
It is a typical line.
The red line represents the mean value, and the green lines each represent 1x standard deviation. The
standard deviation indicates how level the measured line is.

Data Acquisition

3.3.2.1

3.3.2.1.1 .3.2.1.1isi t

To improve sensitivity to dark objects, the exposure time can be increased. This also changes the measuring
repeat time.
Light object: Short exposure time for light, shiny, and reflective surfaces such as metal or white objects, for
example.
Dark object: Longer exposure time and therefore slower measuring frequencies for plastics or black materials,
for example.

3.3.2.1.2 Trigger mode

For setting the measuring intervals.

Free running

Measurement with the max. possible frequency, which may vary depending on the application. The sensor
measures continuously.

Interval

Measurement cycle with fixed internal interval (time in ms). The constant measuring frequencies that can be
achieved are slower than the non-constant frequencies in free-running mode. The interval must be set
accordingly.

NOTE

Sometimes, shiny surfaces may require a longer exposure time.

NOTE

- If Sync-In (pin 8) is connected, free-running mode (or interval mode) runs when Sync-In is set to low

- If Sync-In is not connected, free-running mode (or interval mode) runs continuously

Measurement

NOTE

Single shot

A single measurement is triggered with the falling edge of an external trigger signal at the Sync-In. This
measurement value is held at the outputs until the next falling edge. The measuring frequencies that can be
achieved are only half as high as in free-running mode.

Sync-In

The measurement and signal output can be interrupted with the Sync-In input by connecting with high. As long
as Sync-In is on high, the sensor delays the next measurement (hold) and reduces the power of the laser
beam.

• The sensor checks Sync-In before every measurement

• The previous measurement cycle is always completed first, even if Sync-In is on high

• During the waiting time (Hold), the power of the laser beam is reduced

• While Hold is at high, all outputs are frozen at their last state

• To return the sensor to measurement mode, Sync-In must be set from high to low

• Sync-In must remain on low for at least 5 µs in order for the sensor to begin measuring again

Sync-In low 0…2.5 V Run
Sync-In high 8 V…UB (operating voltage) Hold

Application example: Reciprocal influence

Only the laser beam of Sensor 1 may be in the field of view of Sensor 1. The laser of Sensor 2 must not
influence Sensor 1.

If it is not possible to prevent several sensors from affecting each other through appropriate installation,
however, the sensors affecting each other can be operated asynchronously using the Sync-In cable. The
superordinate control generates the signals for this.

As soon as the Sync-In is set to high (Hold), all output functions are frozen at their
last state until the next measurement.

3.3.2.2.2 Flex Mount

The reference surface is teached with Flex Mount. This enables the sensor to correctly calculate the height of
objects, taking account of its mounting angle and the distance to the reference surface. This function is
recommended to ensure the correct calculation of the object height in relation to the reference surface.

With Flex Mount, the inclination angle and the distance from the reference surface are automatically detected
and saved in the sensor memory so the coordinate system can be rotated correctly. With respect to teaching,
it is important that the teached-in surface is even and covers as much of the entire measuring range of the
sensor as possible.

Flex Mount is used if…

- a standard installation (right angle to the reference surface or the object) is not present

- the reference surface is closer to the sensor than the end of the measuring range Sde

- the reference surface is to be automatically teached and/or shifted in height

- the background is to be suppressed

Effects

- The coordinate system is rotated

- The reference surface is teached; the original sensor reference point is no longer valid

- Objects below the reference surface are ignored

- The axes are no longer referred to as X and Z, but as M and K

- The field of view is reset to the maximum field of view

Reference

Reference surface

With "Reference", it is possible to shift the reference surface in both directions following the teaching process.
This enables, for example, the thickness of the auxiliary plate required during teaching to be deducted again,
or the reference surface to be suppressed.

Example using an auxiliary plate

To compensate for unevenness in the reference surface, a temporary auxiliary plate can be used for the
teaching process.
This plate should be as flat as possible and must conform to the "minimum length of reference surface"1. The
plate must be positioned parallel to the reference surface below it. The thickness of this plate is not important
as long as it is within the field of view of the sensor. The thickness of the auxiliary plate can be deducted again
at the end of the process using "Reference".

Example: Suppressing the reference surface

Shifting the reference surface upward enables the reference surface that was originally teached to be
suppressed.

New position of the reference surface. Everything below is suppressed.

Reference = Shifting the teached-in reference surface (-x mm)

Example:
When using the Delta Height functions (maximum height of the object minus minimum height), the teach-in
reference surface compromises the measurement result.
By setting a reference of -5 mm, the reference surface is placed over the reference surface that was originally
teached, suppressing it and preventing it from having an effect on the measurement result.

Switch point P1 must be larger than switch point P2.

The window must be larger than the "minimum switching window" specified in the data sheet1.

3.3.3.1.1 Polarity

The output level can be inverted with active high or active low here.

It is not recommended to set switch points equal to field of view limits. In
combination with the hysteresis this results in a complex switching behavior.

Precision filter

3.3.3.2

Activating filtering can reduce noise and thus increase resolution and repeat accuracy.
Standard = normal resolution12

High = resolution is approximately twice as high12, measuring rate is reduced
Very high = resolution about three times as high12, measuring rate is reduced

3.3.3.2.1 Influences of the filter

The higher the precision is set, the more response times and release times increase, which means that the
response time for moving objects slows down. The measuring frequency is not affected by the use of this
filter.
The precision filter works with moving median as well as moving average filters.

3.3.3.2.2 Moving median

The median of a finite list is the measurement with the middle measurement value of a string of numbers (e.g.,
median of {3, 3, 5, 9, 11} is 5). The number of measurement values saved in an array is called the number of
measurement values, e.g., {3, 3, 5, 9, 11} corresponds to 5 measurement values. When a new measurement
value is added, the oldest is removed (moving filter). A sudden change in measurement values will only lead
to a change after half of the saved number of measurement values (e.g., number of measurement values = 5
means that the measurement value at the output is only affected after 3 measurement values).

This diagram shows the effects of the median (number of measurement values 5). The filter is used to
suppress measurement errors. The output only changes after a defined number of measurement values
(number of measurement values/2). The measuring frequency is not affected by this filter, but the response
time is.

3.3.3.2.3 Moving average

The output value of the moving average filter is the average of the defined number of measurement values
which have been saved. When a new measurement value is added, the oldest is removed (moving filter).

As shown in the diagram, the moving average evens out the output value. In contrast to the median filter, it is
possible that with the moving average, the displayed measurement values were never measured as such. The
measuring frequency is not affected by this filter, but the response time is.

Number of measurement values required until the correct measurement value is displayed:

- When set to "High", the distance must be stable for 4 + 16 measurement values before the correct
value is displayed

- When set to "Very high", the distance must be stable for 8 + 128 measurement values before the
correct value is displayed

Example

Calculate the response time with a measuring frequency of 500 Hz
1 / 500 Hz = 0.002 s

Median = 7 / 2 (formula: measurement values / 2 ) = 4
Average = 16

Response time = 0.002 * (4 + 16) = 0.04 s = 40 ms

Hysteresis

3.3.3.3

The hysteresis is the difference between the switch on threshold and the switch off threshold, and is specified
as a value in mm. Without hysteresis H, objects in the border area of the switching point could lead to a
toggling of the switching output. For reasons of reliability, the use of hysteresis is recommended (at least as
great as the resolution of the sensor).

The hysteresis can be located before (negative hysteresis) or after (positive hysteresis) a switch point.

4 Communication via the process interfaces

4.1 Introduction

In addition to the configuration option via the integrated web server, the sensor supports Modbus TCP and
OPC UA – two standardized automation technology protocols for configuring and retrieving measurement
values.

4.1.1 Dependencies

The sensor supports one client connection for each protocol. Read access via the protocols is possible at any
time. Write access is only permitted once the sensor has been moved to Configuration mode via the
respective interface. Only one interface can be in Configuration mode at one time. The measuring frequency
that can be achieved may be reduced in such cases.

4.1.2 Description of the commands

See chapter "Configuration via the web interface".

Friday, June 15, 2018 12:44:11 PM/tof V1.0 ANW_81184815 Frauenfeld, Switzerland

4.2 Modbus TCP

Modbus TCP is a protocol with a long history which is supported by a large number of programmable logic
controllers as standard or which can easily be retrofitted using a software module. Libraries for various
programming languages are available for PC-based systems. The standard is freely available on the website
of the Modbus Organization (http://www.modbus.org).

4.2.1 Protocol parameters

The Modbus TCP server integrated in the sensor (Modbus TCP slave) can be addressed using the following
parameters:

• TCP port no.: 502

• Modbus TCP unit identifier: 1

4.2.2 Mapping the sensor functionality to the Modbus data model

The sensor functionality can be accessed by reading or writing entries in the "Discrete inputs", "Input
registers", and "Holding registers" tables. The following Modbus function codes (FC) are supported here:

• Read Discrete Inputs (FC 02)

• Read Input Registers (FC 04)

• Read Holding Registers (FC 03)

• Write Single Holding Register (FC 06)

• Write Multiple Holding Registers (FC 16)

The three tables are independent of one another, meaning that the same address can represent a different
functionality in the different tables. The number of the register to be read or written with a Modbus command
must match the length specified for the respective sensor functionality. It is not possible to read or write just
some of the parameters.
If the data type of a sensor parameter is wider than a 16-bit Modbus register, the parameter is split across
several Modbus registers. In such cases, the lower-value bits are placed on the lower address and the higher­value bits on the higher address.

To enable all measurement values to be retrieved in full with the maximum measurement rate, all
measurement values are stored in a buffer containing up to 100 entries. When accessing the input register
with address 600, the content of the buffer is copied to the Modbus TCP output buffer. From here, the content
can then be retrieved sequentially in multiple sub-blocks. Each sub-block contains six measurement values.

4.3 OPC UA

OPC UA is a mature and convenient protocol which was specially developed to meet automation technology
requirements. The client functionality required is already partially supported by programmable logic
controllers. Various software libraries are available for PC-based systems. Further information is available on
the website of the OPC Foundation (https://opcfoundation.org). An example of how a freely available OPC UA
client can be used is described below.

4.3.1 Commissioning with the UaExpert OPC UA Client

The UaExpert software described can be acquired from https://www.unified-automation.com/downloads/opc-

Response time

Measuring value display

5.2 Measuring frequency, measuring repeat time, and response time

A complete measurement cycle consists of exposure, calculation, and measuring value display. In order to
increase the measuring speed, process steps are executed simultaneously.

Exposure

Calculation

repeat time

5.2.1 Measuring frequency and measuring repeat time

The time between two exposure times is referred to as measuring repeat time. This time can be converted into
a frequency (Hz), which indicates how many measurement values can be issued by the sensor in one second.

[] =



ℎ[]

5.2.2 Automatic exposure control

The color and surface of the object have an influence on the amount of reflected light. A longer exposure time
is required for dark objects than for light objects. The sensor automatically controls the exposure time on the
basis of the amount of light reflected by the object. This slows down the measuring frequency and the
response time. In this case, the degree of slowdown is dependent on the laser class of the sensor.

5.3 Alarm output

The alarm signal is output as a push-pull signal (active high). It is set when the object is outside the measuring
range or the signal quality is insufficient for evaluation. If the signal quality is insufficient, the analog and
switching outputs for 75 measurement cycles are kept at the last valid value. After this time has elapsed, the
analog and switching outputs are set as if an object were at the start of the measuring range.

NOTE

As soon as the alarm output is active, the analog and switching outputs for 75
measurement cycles are kept at the last valid value.

Distance from the sensor

5.4 Object to be measured

5.4.1 Smallest detectable object

For an object to be reliably detected, it must conform to the minimum object width1. This minimum object width
varies with the distance from the sensor.

Smallest detectable object – near

Smallest

detectable object

Smallest detectable object – far

5.4.2 Reflectivity

Light objects are generally easier to detect than dark objects, since they are more reflective. Reflectivity is the
percentage relationship between incident and reflected light.

Definition of objects:

Object white approx. 90%

reflectivity
Object black approx. 6% reflectivity
Object light > 18% reflectivity
Object dark 6…18% reflectivity

5.4.3 Standard object

The technical data for sensors in the data sheet refers to measurements with a Baumer standard object. This
standard object is precisely defined in size, shape, and color, making multiple measurements comparable.

Standard object definition:

• Ceramics white (reflectivity approx. 90%)

• Smooth, flat surface

• Covers entire sensor measuring range

5.6 Error correction and tips

Error Error correction

No function • Check connection. Power supply 15…28 VDC on pin 2 (+Vs,

brown) and pin 7 (GND, blue)
Green LED flashes • Short circuit on switching outputs. Check connection
Red LED lights up • Object outside field of view (near, far, or to the side)

• Amplitude of the received signal is insufficient (e.g., in case of
soiling)

Sensor does not provide the
expected measuring results

The sensor does not take
account of all objects within the
field of view

Unreliable measurement value:
The measurement value jumps
back and forth

Transmitting laser light is dim Sync-In input is on High--> set to Low
Incorrect measurement values This is probably due to a malfunction caused by ambient light. Attempts

A communication error occurs
during changing the IP address
No tool status message during
an error

• Check inclination angle and work in Flex Mount mode if required
(teach the new reference surface)

• The object is not in the measuring range

• Bright object, avoid direct reflexes from the transmitter to the

receiver

• Enlarge field of view. The field of view was possibly limited; see
Section "FIELD OF VIEW"

• The red visible laser beam does not represent the maximum field
of view. If the object is at the edge of this beam it could be outside
the measuring range

• Move object. The object is outside the field of view vertically or is
in the blind region of the sensor

• The object is not in the measuring range

• Avoid bright object

• Avoid very dark object

• Too much ambient light

• Check measurement mode setting (MEASUREMENT MODE)

should be made to reduce the ambient light
If the IP address is changed, it must be reconnected to the sensor

A tool status message only states that the communication with the sensor
that was initiated by the call was successful. If there are problems, for
example when teaching with Flex Mount, this is returned by the sensor as
an error code

ATTENTION!

6.3 Front optic

In the event of a broken front optic, defective display, or loose or exposed laser lens, the sensor must be
disconnected from the power supply immediately. It must not be put into operation again until it has been
inspected by an authorized person. Non-compliance with these safety instructions may lead to the release of
hazardous laser beams.

The use of a sensor with a broken front optic or loose or exposed lens can
lead to hazardous laser radiation.

6.4 Cleaning the sensors

The laser distance sensors do not require any maintenance, except that the front windows must be kept
clean. Dust and fingerprints can impair sensor function. It is normally sufficient to wipe the windows with a
clean (!), soft lens cleaning cloth. Alcohol or soapy water can be used in case of severe soiling.
The display and the keys must be kept free from dirt and moisture. Water and dirt on the keys can impair their
function.

ATTENTION!

Protect optical surfaces from moisture and dirt.

6.5 Disposal

This sensor contains electronic components. Dispose of parts according to country-specific provisions.
