3 Functions and features

3.1 General description

The sensor projects a laser line onto the object and determines the height profile of the object along the laser line by means of the triangulation principle.

The object to be detected has to be in the sensor's operating range.

The sensor has a trapezoidal operating range with the following dimensions:

• distance to the sensor (Z direction): 150...300 mm
• length of the profile (X direction):

• for an object distance of 150 mm: 45 mm
• for an object distance of 300 mm: 90 mm

ATTENTION

The unit may cause radio interference in domestic areas. In this case it can be necessary for the user to take appropriate measures.

1: X axis in [mm]
2: Z axis in [mm]
3: transmitter
4: receiver
5: ROI marking

Fig. 1

The projected laser line is wider than the operating range. The object to be detected should be positioned in the centre of the laser line.

For the factory setting the operating range is limited by two vertical ROI markings projected in green.

The ROI markings are not visible if the sensor is controlled via the "Vision Assistant" software.

3.1.1 Teaching and height profile

In the first step, the sensor is taught (teaching process). The entire height profile covered by the laser line is captured. The user can then further narrow the ROI.

- The height profile of this ROI is saved as taught reference profile.

In the next step, the sensor continually detects height profiles, compares them to the taught reference profile and generates a matching value. Now the user can set a switching threshold ( → 3.2).

1: X axis in [mm]
2: Z axis in [mm]
3: sensor
4: taught reference profile

Fig. 2

3.1.2 Normal operation

In normal operation, the sensor detects height profiles, continually or upon triggering, and compares them to the taught reference profile in order to generate a matching value.

If the "Vision Assistant" software is used, high-resolution images of the profiles are transmitted additionally ( → 4.1.3). The height profiles are referred to the max. measuring distance = 300 mm (reference height). The reference point for the reference height is the optical zero point of the transmitter. It is inside the sensor. Example: The distance between the sensor and the object is approx. 200 mm. In the "Vision Assistant" software, the height profile has a base height of approx. 100 mm.

• Profile heights are referred to the reference height and therefore have positive absolute values.
• All data sheet indications refer to the dimensions of the object profiles and not to the absolute distances between them and the sensor. The object profiles are displayed with real dimensions (object profile width/height) regardless of the object profile's position in the operating range.

3.2 Interpretation of the matching value

The measured height profile (in the following also referred to as "profile") is compared internally to a taught reference profile. The degree of match is generated as an internal measured value (matching value).

The measured value determined by the sensor hence describes the degree of match between the measured profile and the taught reference profile.

Matching value provided in [%]	Description
100	There is a 100 % match between the measured profile and the taught reference profile.
50	There is a 50 % match between the measured profile and the taught reference profile.

The matching value to be tolerated must be determined by the user during set-up and should be used as switching threshold for the following differentiation:

• good parts
• bad parts

The transition between good parts and bad parts is determined by measurement and used as switching threshold.

No particular switching threshold is recommended. It has to be determined according to the respective application.

3.2.1 Fluctuation of the matching value

Natural fluctuations (noise, drift) affect the measured matching value.

As a rule, these measurement fluctuations cause the matching value to be < 100%, even if the taught object is measured again.

The measurement uncertainty for the detection of height profiles is described using the following figures:

Gz - accuracy in Z direction (profile height)

Gx - accuracy in X direction (profile width)

1: sensor
2: measurement uncertainty
3: object profile
4: operating range
5: accuracy in Z direction (Gz)
6: accuracy in X direction (Gx)

Fig. 3

This means that Gz/Gx also defines the:

• minimum object height to be detected reliably
• minimum object width to be detected reliably

The height profiles are internally detected by the sensor with a higher resolution than Gz/Gx. Changes in object height/width can therefore be detected within the measurement uncertainty.

3.3 Applications

The photoelectric sensor is particularly suitable for process quality assurance, more precisely monitoring of workpiece shapes and fault detection.

Examples:

• Monitoring of the processing quality, e.g. diameters of drill holes.
• Check of workpieces for faulty processing, e.g. missing drill holes.

During the measurement, the workpiece has to be still.

• For static situations, the continuous measurement mode has to be set. The sensor permanently monitors the workpiece and signals deviations from the taught reference profile ( → 10.1).
• For dynamic situations, the triggered measurement mode has to be set. A higher-level process control unit decides when the detection takes place and ensures that the workpiece is in the detection zone and that it does not move ( → 10.2).

4 Function

The photoelectric sensor detects the height profile of the object in the operating range, continually or upon triggering, by means of triangulation. Besides, the photoelectric sensor has an IO-Link interface.

The sensor can be used in three different modes of operation:

• switching mode (→ 4.1.1)
  • operation with an IO-Link master ( → 4.1.2)
  • operation with the Vision Assistant via the IO-Link interface ( → 4.1.3)

4.1 Operating modes

4.1.1 Switching mode

In switching mode, the sensor is directly connected to the process control unit and transmits information on good part / bad part via the switching output.

If the set switching threshold is exceeded/not reached, this is signalled by means of switching signals on switching output 1/2. The switching outputs act complementary ( → 6 Electrical connection).

As an option, the time at which the measurement is taken can be controlled by a process control unit via the trigger input (pin 5). The sensor signals the successful start of the measurement and the availability of switching information via switching output 2. The higher-level process control unit defines the measurement period. ( → 10.2)

4.1.2 Operation with IO-Link master

If the sensor is connected to an IO-Link master, parameter setting, triggering and data recording can be done completely via IO-Link. The cyclic process data include the matching value and the switching information (good part / bad part).

Additional functions are available via IO-Link:

• detection of the number of trigger processes
• device identification

More information → www.ifm.com → Data sheet.

4.1.3 Operation with the Vision Assistant parameter setting software and an IO-Link master

Via the IO-Link protocol, high-resolution profile images are continually transmitted. The image data of a profile image is split up into several data packages and transmitted in a sequence of IO-Link data frames.

The ifm software package Vision Assistant includes a corresponding protocol handler that combines the profile images and visualises them.

This simplifies the teaching process (guided teach), as the detection zone of the sensor and the assessment of the profiles is visualised base on the profile images.

Prerequisite:

• IO-Link master
• ifm parameter setting software "ifm Vision Assistant" (E3D300)

Additional functions are available with the Vision Assistant software package:

• Overlay of the ROI in high-resolution profile images for a very precise setting.
• Extensive status information, useful in difficult measurement situations.

Visualisation of profiles can also be done using a customer-specific software. The information required for this can be found in the IODD.

More information → www.ifm.com → Vision Assistant.

5 Installation

5.1 Installation conditions

▶ Install the unit so that the object to be detected is within the sensor's detection zone.
▶ For direct installation, fix the unit using two M4 screws.

Further accessories → www.ifm.com → Data sheet → Accessories.

5.2 Installation instructions

5.2.1 Lateral inclination

1: dead zone due to shadowing

Fig. 4

The sensor should be aligned as vertically as possible to the object to be detected. In case of lateral inclination ( → Fig. 4) and vertical object edges, the laser line will be partially interrupted. The profile cannot be detected in this area. You can avoid this by reducing the inclination angle.

5.2.2 Front inclination

Fig. 5

If the sensor is inclined forwards or backwards, make sure that the laser line reflected by the object can be detected by the receiver → Fig. 5. It can be ensured that the receiver detects the laser line by reducing the inclination angle or rotating the sensor by 180° .

The use of the "Vision Assistant" software facilitates the detection of such problems.

5.2.3 Saturation and signal loss

The sensor automatically sets the exposure time for the capture of the height profile so that saturation is avoided.

Highly reflective surfaces lead to extreme contrasts. In some cases, this may lead to individual points within the ROI not being detected.

Avoid signal losses by slightly changing the sensor position:

• incline the sensor laterally or frontally
• increase or decrease the object distance

5.2.4 Avoidance of multiple reflections

1: sensor
2: object
3: multiple reflections

Fig. 6

▶ Slightly change the sensor position – e.g. incline the sensor laterally or frontally, increase or decrease the distance to the object.

5.2.5 Avoidance of soiling and ambient light

Preferably align photoelectric sensors with the front lens facing downwards or parallel to the earth's surface.

Background:

• Photoelectric sensors are sensitive to direct radiation of light sources. Everyday light sources (lamps, sun) radiate from above.
  • Photoelectric sensors react sensitively to soiling, as it reduces the excess gain.

Dust deposits can be reduced by downwards or sideways orientation. This allows for longer cleaning intervals.

Make sure that sensors installed with their front lens facing upwards are not oriented towards roof windows or ceiling lamps.

6 Electrical connection

The unit must be connected by a qualified electrician.

▶ The national and international regulations for the installation of electrical equipment must be adhered to.
▶ Ensure voltage supply to EN 50178, SELV, PELV. OPD100: cULus, supply class 2

▶ Disconnect power.

▶ Connect the unit as follows:

	OPD100 PNP/NPN

Core colours of ifm sockets:

1 = BN (brown), 2 = WH (white), 3 = BU (blue), 4 = BK (black), 5 = GR (grey).

Pin	Continuous mode (factory setting)	Triggered mode
1	VDD	VDD
2	OUT2 = switching output	OUT2 = ready signal (switching output)
3	GND	GND
4	OUT1 = switching output / IO-Link	OUT1 = switching output / IO-Link
5	trigger input of the PLC	trigger input of the PLC

In the operating mode "Continuous mode", OUT1 and OUT2 are configured as complementary switching outputs.(→ 10.1)

In the operating mode "Triggered mode", OUT2 is configured as ready signal. ( → 10.2).

Complementary outputs transmit the same sensor information with oppositional logic levels. This means that both an NC and NO switching output are available at the same time.

OUT1 can e.g. be used for the detection of good parts, OUT2 for the detection of bad parts.

6.1 Operation with IO-Link master

The unit is compatible with IO-Link master port class A (type A).

For operation with IO-Link master port class B (type B) observe the following:

As a standard, the unit is not compatible with master port class B (type B). Pin 2 and pin 5 are used for manufacturer-specific functions. That means that the main supply voltage of the unit and the additional voltage supply (master port class B on pins 2/5) are not electrically isolated.

With the following configuration the unit can be used with master port class B:

- Connect unit and IO-Link master via 3 wires: Connect pins 1, 3 and 4 of the unit with the IO-Link master (do not connect pins 2 and 5).

2:	1 x LED green	Active LED = power
3:	Graphic display	Display of the measured matching value.
4:	Programming button [ENTER]	Selection of the parameters and acknowledgement of the parameter values.
5:	Programming button [Up]	Setting of the parameter values (scrolling by holding pressed; incrementally by pressing once).
6:	Programming button [Down]	Setting of the parameter values (scrolling by holding pressed; incrementally by pressing once).

8 Set-up

▶ After installation, electrical connection and programming, check whether the unit operates correctly.

▷ If the unit has been correctly set up, the sensor starts with the "Guided Teach" ( → 8.1). The settings made last are internally stored by the sensor.

When the sensor is switched on for the first time after a reset, it will also start with the "Guided Teach", as the taught reference profile is deleted in case of a reset.

Lifetime of a laser diode: 50000 hours.

After successful teaching, the sensor should not be moved again. Any change of the sensor position will lead to the taught reference profile not being recognised reliably. The sensor must be taught again if it has been moved.

The sensor needs a warm-up period of ≥ 10 min. The performance parameters specified in the data sheet only apply after this warm-up period. The teaching of objects should also be done in the warmed-up state.

8.1 Guided Teach

▲ = [Up] button

▼ = [Down] button

8.1.1 Language selection

▶ Put the sensor into operation.

▷ The available languages are indicated in the display.
▶ Select the desired language with the [Up] or [Down] button and confirm with [ENTER].

8.1.2 Teaching an object

In the next step, the profile is taught.

▷ The request [Place object and press confirm] is displayed.
▷ The sensor emits a red laser line with two vertical green ROI markings.
▶ Place the sensor so that the laser line covers the area to be monitored and the object is within the operating range of 150...300 mm → 3.1 → Fig. 1.
▶ Start the teaching process by pressing [ENTER].
▷ The sensor repeatedly measures the profile of the object/background.
▶ Select [Confirm] or [Back] using the [Up] or [Down] button and press [ENTER].

• [Confirm]: Taught profile is saved.
• [Back]: Teach the profile again.

The object should not be moved during measurement. The end of the measurement is not only indicated in the display, but also via the laser line flashing twice.

If the object to be detected is outside the operating range (e.g. closer than 150 mm or farther away than 300 mm), the teaching process is stopped. The message [Object out of range] appears for three seconds. Afterwards, a new teaching process is started.

8.1.3 Set ROI

The sensor makes it possible to select an ROI from the entire taught height profile. The profile section included in this ROI is saved as reference profile and used to determine the matching value.

Based on this restriction, the assessment of the height profile can be limited to the relevant section. Deviations regarding other, irrelevant sections are not taken into account.

In the next step, the ROI is set.

▷ The options [Define ROI] and [Back] are displayed.

▶ Select [Define ROI] or [Back] using the [Up] or [Down] button and press [ENTER].

- [Define ROI]: Define an ROI from the entire profile taught.

- [Back]: Teach the profile again.

▷ [Set left ROI mark] is displayed. ▶Move the green marking line using the [Up] or [Down] button. ▷ The left marking line shifts. ▶After reaching the requested position, confirm with [ENTER]. ▷ The position of the left marking line is set. ▷ The selected section is detected again (new profile).
▷ [Set right ROI mark] is displayed. ▶Move the green marking line using the [Up] or [Down] button. ▷ The right marking line shifts. ▶After reaching the requested position, confirm with [ENTER]. ▷ The position of the right marking line is set. ▷ The selected section is detected again (new profile).

Red line indicated in the display: represents the section covered by the laser line. White marking: represents the fixed marking line. Green arrow: represents the marking line to be moved.

The standard setting for the ROI includes the entire operating range. If the markings are not moved, but confirmed, the entire profile taught is used for assessment.

8.1.4 Set the position of the reference profile

In the previous step, a reference profile was taught from the ROI. In the next step, you can define the section in which the measured height profile is to be searched. There are two options:

Fixed:

The reference profile is searched in the ROI defined during teaching. As during teaching, the objects to be monitored must be positioned very exactly during operation.

Floating:

However, due to mechanical or manual shifting tolerances it is not always possible to position the object to be monitored the right way round. With the option [Floating], this problem can be avoided. The taught reference profile is searched across the entire detected height profile. The taught reference profile can be successfully detected along the X and Z axis despite a change in position.

Marking function: During teaching, the ROI is indicated via two vertical marking lines projected in green (ROI markings). This way, the user can see what section of the laser line is defined as ROI. After teaching has been finished, the marking lines disappear. However, they can be displayed manually ( → 11.1 Parameter level basic functions).

In the next step, the position of the ROI is defined.

▷ The options [Fixed], [Floating] and [Back] are displayed.

▶ Select [Fixed], [Floating] or [Back] using the [Up] or [Down] button and press [ENTER].

• [Fixed]: No shift of the object is permitted.
• [Floating]: A shift of the object in X direction (along the laser line) and in Z direction is permitted.
• [Back]: Return to → 8.1.3 Set ROI.

8.1.5 Switching threshold

In the next step, the switching threshold for the switching output is set. The standard setting is 90%.

1: matching value
2: switching threshold

▷ The sensor continually detects new height profiles and compares them to the taught reference profile.
▷ The matching value is shown in the display.

If matching value > switching threshold (standard = 90 %): measured value display is green → good part.

If matching value < switching threshold (standard = 90 %): measured value display is red → bad part.

Natural fluctuations (noise, drift) affect the measured matching value. As a rule, these measurement fluctuations cause the matching value to be < 100%, even if the taught object is measured again. ( → 3.2.1)

▷ The options [Adjust threshold], [Save settings] and [Back] are displayed.
▶ Select an option using the [Up] or [Down] button and press [ENTER].

- [Adjust threshold]:

▶ Set the value for the new threshold using the [Up] or [Down] button and press [ENTER].
- [Save settings]: Set-up is completed and the sensor is put to the Run mode.
- [Back]: Return to → 8.1.4 Set the position of the reference profile.

By testing several good parts / bad parts with different switching thresholds, the setting can be optimised for the application. The good part / bad part assessment is indicated in the display.

Use the extended functions to individually adjust the colour assignments. Standard: green value → good part / red value → bad part

8.1.6 Run mode

After set-up via a "Guided Teach", the sensor is put to the Run mode. The unit is ready for operation.

It continually detects profiles and compares them to the taught reference profile based on the set switching threshold.

The result (good part/bas part) is provided:

- Visually via the display:

• good part: matching value indicated in green if matching value ≥ switching threshold

• bad part: matching value indicated in red if matching value < switching threshold

• Visually via the switching status indication: colours according to the set function

• Switching output: Depending on the set function, OUT1 is switched or not switched.

In the status line of the display, the measurement state is indicated:

• Profile X: → undisturbed operation
- Warnings / errors: → see error table(→ 13 Troubleshooting).

10 Operating modes

10.1 Continuous mode

The default mode is the "Continuous mode".

The sensor continually measures and compares the measured profiles to the taught reference profile, taking into account the switching threshold.

10.2 Triggered mode

In this mode, the sensor starts the measurement after receiving an external trigger signal.

The sensor compares a single profile to the taught reference profile taking into account the switching threshold.

The external trigger signal must be provided by the higher-level process control unit (e.g. PLC) and can be transmitted physically via pin 5 or via IO-Link.

The sensor then signals the successful start of the measurement, and, a little later, the availability of the switching information via switching output 2 (ready signal) or IO-Link. The higher-level control unit has full control of the assessment time ( → Fig. 7).

Fig. 7

2: trigger signal
3: ready signal
4: switching signal

5: positive trigger edge / ready signal is reset
6: switching information is set
7: switching information is available (measurement terminated) / ready signal is set

This operating mode is particularly recommended for dynamic applications. The higher-level process unit only starts the measurement if the object to be detected does not move. The switching output corresponds to the object's status.

The [Trigger delay] delays the start of the measurement (referred to the external trigger signal). This does not affect / delay the ready signal provided by the sensor.

11 Parameter setting

During parameter setting the unit remains internally in the operating mode. It continues its monitoring function with the existing parameters until the change has been completed.

12.1 General information

This unit has an IO-Link communication interface which requires an IO-Link-capable module (IO-Link master) for operation.

The IO-Link interface enables direct access to the sensor values and parameters and provides the possibility to set the parameters of the unit during operation. In addition, communication is possible via a point-to-point connection with a USB adapter cable.

You will find more detailed information about IO-Link at www.ifm.com.

12.2 Device-specific information

You will find the IODDs necessary for the configuration of the IO-Link unit and detailed information about sensor values, diagnostic information and parameters in the overview table at www.ifm.com.

12.3 Parameter setting tools

You will find all necessary information about the required IO-Link hardware and software at www.ifm.com.

12.4 Functions

With IO-Link all functions and measured data are available that can also be accessed via the display and pushbuttons on the unit.

All functions are described in detail in the IODD.

13 Troubleshooting

13.1 Error indications in the display

Display	Possible cause	Solution
Running	Sensor running in standard mode. There is no failure.	No need for action
Object out of range	Object is outside the operating range (too far / too close). No height profile and matching value can be determined.	Enlarge the distance to the object. The detected profile must be in the operating range 150...300 mm.
Short circuit OU1	Short circuit in switching output 1.	Check the wiring.
Short circuit OU2	Short circuit in switching output 2.	Check the wiring.

13.2 Error indications in the "Vision Assistant" software

Display	Possible cause	Solution
Low amplitude	The data points of the detected laser line have a very low intensity.	If all (352) data points are concerned:·Object is outside the operating range or is extremely dark. ▶ Check the distance to the object. If only a few data points are concerned:·Object features large differences in luminosity. Due to the characteristics of the object, some of the reflected laser beams do not reach the receiver. ▶ Change the position of the sensor or the object.
High amplitude	The data points of the detected laser line have a very high intensity.	In case of a fixed integration time: ▶ Reduce the time or change the setting to [Auto]. In case of large differences in luminosity: ▶ Change the position of the sensor or the object.
	Laser line is too thick due to:- translucent surfaces such as skin, rubber- multipath propagation on shiny surfaces	▶ Enlarge the distance to the object. ▶ Change the position of the sensor or the object.
Multiple lines	Sensor receives several reflections due to:- semi-transparent objects, laser line is reflected at two planes- shiny surfaces on sharp profiles	▶ Change the angle of incidence. If possible, darken the background. ▶ Change the position of the sensor or the object.
Too near / far	Data points outside the operating range in Z direction (< 150 mm, >300 mm)	▶ Place the object within the operating range (150...300 mm).

The profile images detected consist of 352 data points. Faulty data points are indicated as a dashed line in the "Vision Assistant". These data points are not used for determining the matching value.

The data errors and the number of data points concerned for the currently measured height profile are shown in the Vision Assistant. E.g.

13.3 Other types of incorrect behaviour

Situation	Possible cause	Solution
Object cannot be taught."Object out of range" is displayed despite the object being in the operating range of 150...300 mm.	Due to the sensor being inclined frontally and the characteristics of the object / background, some of the reflected laser beams do not reach the receiver.	▶ Slightly change the sensor position (front inclination, reduce/enlarge the distance to the object). ▶ If possible, rotate the sensor or the workpiece by 180°.
Sensor has been taught successfully. However, the matching value is very low (also for the taught object).	Sensor has been moved after teaching. Info: After a successful [Guided Teach], the sensor should not be moved again. Any change in position will lead to the taught reference profile not being recognised reliably.	▶ Teach the sensor again.
Sensor has been taught successfully. However, the matching value is significantly lower than 90% for very similar workpieces.	The new workpieces may have slightly different surface characteristics, e.g. reflective surfaces.	▶ Incline the sensor slightly frontally or laterally and teach it again. ▶ Or: check whether the width of the reference profile can be further limited. Then teach the sensor again. ▶ Or: manually adapt the [Integration time]. ▶ Or: reduce the switching threshold.
Sensor has been used for a while. Good parts are assessed to be bad parts. The matching value is below the set switching threshold.	Sensor has been moved unintentionally.	▶ Teach the sensor again.
	Front side of the sensor is soiled.	▶ Clean the front side. ▶ If necessary, change the sensor position to avoid soiling and teach the sensor again.

14 Maintenance, repair, disposal

Faulty sensors must only be repaired by the manufacturer.

▶ Keep the front lens of the sensor clean.
▶ After use dispose of the unit in an environmentally friendly way in accordance with the applicable national regulations.
▶ Do not open the module housing. There are no user-serviceable components inside.
