Functional Principle, Technical Data

3. Functional Principle, Technical Data

3.1 Short Description

The optoNCDT 1320 uses the principle of optical triangulation, that is, a visible, modulated point of light is projected onto the target surface.

The diffuse part of the reflection of this point of light is displayed depending on distance on a position-resolving element (CMOS) by an receiver optic which is arranged to the optical axis of the laser beam in a defined angle.

A signal processor in the sensor calculates the distance of the point of light on the measuring object to the sensor by means of the output signal of the CMOS elements. The distance value is linearized and output by means of the analog or RS422 interface.

5.1 Notes for Operation

5.1.1 Reflection Factor of the Target Surface

In principle the sensor evaluates the diffuse part of the reflected laser light.

Ideal diffuse reflection

Direct mirror reflection Real reflection

Fig. 5 Reflection factor of the target surface

A statement concerning a minimum reflectance is difficult to make because even a small diffuse fraction can be evaluated from highly reflecting surfaces. This is done by determining the intensity of the diffuse reflection

from the CMOS signal in real time and subsequent compensation, see Chap. 3.2

. Dark or shiny objects being

measured, e.g. black rubber, may require longer exposure times. The exposure time is dependent on the measuring rate and can only be increased by reducing the sensor’s measuring rate. optoNCDT 1320 Page 19

Installation

5.1.2 Error Influences

5.1.2.1 Light from other Sources

Thanks to their integrated optical interference filters the optoNCDT 1320 sensors offer outstanding performance in suppressing light from other sources. However, this does not preclude the possibility of interference from other light sources if the objects being measured are shiny and if lower measuring rates are selected.

Should this be the case it is recommended to use suitable shields to screen the other light sources. This applies in particular to measurement work performed in close proximity to welding equipment.

5.1.2.2 Color Differences

Because of intensity compensation, color difference of targets affect the measuring result only slightly. However, such color differences are often combined with different penetration depths of the laser light into the material. Different penetration depths then result in apparent changes of the measuring spot size. Therefore color differences in combination with changes of penetration depth may lead to measuring errors.

5.1.2.3 Temperature Influences

When the sensor is commissioned a warm-up time of at least 20 minutes is required to achieve uniform temperature distribution in the sensor. If measurement is performed in the micron accuracy range, the effect of temperature fluctuations on the sensor holder must be considered. Due to the damping effect of the heat capacity of the sensor, sudden temperature changes are only measured with delay.

5.1.2.4 Mechanical Vibration

If the sensor is to be used for resolutions in the μm to sub-μm range, special care must be taken to ensure stable and vibration-free mounting of sensor and target.

5.1.2.5 Movement Blurs

If the objects being measured are fast moving and the measuring rate is low, it is possible that movement blurs may result. Always select a high measuring rate for high-speed operations, therefore, in order to prevent errors.

5.1.2.6 Surface Roughness

Laser-optical sensors detect the surface using an extremely small laser spot. They also track slight surface unevenness. In contrast, a tactile, mechanical measurement, e.g. using a caliper, detects a much larger area of the measurement object. In case of traversing measurements, surface roughnesses of 5 μm and more lead to an apparent distance change.

Suitable parameters for the averaging number may improve the comparability of optical and mechanical measurements.

 h > 5 µm

Ceramic reference surface Structured surface

Recommendation for parameter choice:

- The averaging number should be selected in such a way that a surface area the size of which is comparable to those with mechanical measurements is averaged.

5.1.2.7 Angle Influences

Tilt angles of the target in diffuse reflection both around the X and the Y axis of less than 5 ° only have a disturbing effect with surfaces which are highly reflecting.

These influences have to be explicitly considered when scanning profiled surfaces. Basically the angle behavior of triangulation is liable to the reflectivity of the measuring object surface.

Never fall below the bending radius for the sensor cable of 30 mm (fixed) or 60 mm (dynamic).

i

The fixed connected sensor cables are not cable carriers suitable.

i

Unused open cable ends must be insulated to protect against short circuits or malfunction of the sensor.

Avoid excessive pulling to the cables.

Provide strain relieves near the connectors when cables > 5 m are vertically free hanging.

Connect the cable shield to the potential equalization (PE, protective earth conductor) on the evaluator

(control cabinet, PC housing) and avoid ground loops.

Never lay signal leads next to or together with power cables or pulse-loaded cables (e.g. for drive units and solenoid valves) in a bundle or in cable ducts. Always use separate ducts.

Operation

6. Operation

6.1 Getting Ready for Operation

Install and assemble the optoNCDT 1320 in accordance with the instructions set out, see Chap. 5.

Connect the sensor with the indicator or monitoring unit and the power supply.

The laser diode in the sensor can only be activated if at the input Laser on/off Pin 8 is connected with Pin 12, see Chap. 5.4.4

.

Once the operating voltage has been switched on the sensor runs through an initialization sequence. This is indicated by the momentary activation of all the LEDs. Once initialization has been completed, the sensor transmits a „->“ via the RS422 interface. The initialization takes up to 10 seconds. Within this period, the sensor executes the Reset or the Bootloader command through the key select only.

To be able to produce reproducible measurements the sensor typically requires a start-up time of 20 minutes.

If the LED output is off, this means that there is no supply voltage.

If the LED state

is off, this means that the laser light source has been switched off.

Operation

6.3 Programming via ASCII Commands

As an added feature you can program the sensor via an ASCII interface, physically the RS422.

This requires, that the sensor must be connected to a serial RS422 interface via a suitable interface converter, see Chap. A 1 , to a PC / PLC.

Pay attention in the programs used to the correct RS422 default setting.

Once connected, you can transmit the commands from the appendix, see Chap. A 3 , via the terminal to the sensor.

6.4 Timing, Measurement Value Flux

The sensor requires three cycles for measurement and calculation without triggering:

Each cycle takes 500 μs at a measuring rate of 2 kHz. The measured value N is available at the output after three cycles. The delay between acquisition and output is therefore 1500 μs. As the processing in the cycles occurs parallel, after another 500 μs, the next measured value (N+1) is output.

The optoNCDT 1320 measurement output is controllable through an external trigger signal or a command.

Triggering affects the analog and digital output.

The measurement value at the time of triggering is output

delayed, see Chap. 6.4

.

- Triggering does not influence the timing so that between the trigger event (level change) and the start of output always lie 3 cycles + 1 cycle (Jitter).

- The multifunctional input is used as external trigger input, see Chap. 5.4.7

Starts measured value acquisition or output as soon as the chosen edge is applied to the trigger input. The sensor outputs a fixed number of measurement values when trigger conditions have been met. Value range from 1 ... 16383. After termination of data output the analog output sticks to the last value (sample & hold).

Software triggering.

Starts the measurement value output, when a software command comes. The trigger time is defined more inaccurately. After the trigger event the sensor outputs the preset number of measurement values or starts a continuous measurement value output. If “0“ is selected for the number of measurement values, the sensor stops the triggering and the continuous value output.

Measurement output can also be stopped by means of a command.

7.4.4.2 Signal Processing - Value Output Trigger

Measurement values are calculated continuously and independently of the trigger event. A trigger event simply triggers the value output via a digital interface. Therefore, any values measured immediately before the trigger event are included in calculating mean values (averages). optoNCDT 1320 Page 51

7.4.7 Zeroing and Mastering

By zeroing and mastering you can set the measurement value to a set point in the measuring range. The output range is moved thereby. This function makes sense, for example, for several adjacent measuring sensors or in the case of the thickness and planarity measurement.

Zeroing/

Mastering

Inactive

Normal measurement value or Zeroing/Mastering is undone.

Active

Value Indication, e. g. of thickness of a master part.

Value range max. 0 up to +2 x measuring range

Setting masters is used to compensate mechanical tolerances in the measurement setup of the sensors or to adjust the temporal (thermal) changes in the measurement system. The masters measurement, also a known as the calibration measurement, is given a set point.

The value which is given during measurement on the sensor output of the “mastering object“ is the master value . The zero-setting is a characteristic of the mastering, because here the master value is 0 .

When mastering the sensor‘s characteristic is parallel displaced. The displacement of the characteristic curve reduces the usable measurement range of the sensor the further the master value is away from the master position.

Sequence for Mastering / Zeroing:

Bring target and sensor in the desired position together.

Send the master command.

The master command waits for 2 seconds on the next measurement value and masters it. If no measurement value is received within this time, for example by external triggering, the command returns with the error

E220 Timeout back.

After the mastering, the sensor gives new measurement values, related to the master value. The non-mastered condition applies by means of a reset with the button Inactive .

i

Zeroing/Mastering requires that a target is within the measurement range.

Zeroing/Mastering has an influence on the digital and the analog output.

An invalid master value, e. g. no peak available, will be acknowledged with the

E602 Master value is out of range error.

- Error value: 3.0 mA ( ±10 μA)

The teaching scales the analog output (4 to

20 mA) for a part of the measuring range. This allows you to optimize the resolution for the analog measurement range. Only the current and switching output will be affected by the 2 point calibration. Therefore you define a new start and end for the measurement range. This teaching procedure can be performed live via the select key, the multifunctional input or via the webinterface.

i

With a user defined output scaling you

can use the error output, see Chap. 5.4.8

, as a programmable limit switch.

The measurement object positions for Teach 1 and

Teach 2

have to differ from each other.

The teaching process requires a valid measuring signal. The teaching process is terminated at

- no target,

- target not evaluated,

- to close to the sensor - beyond SMR or

- to far from the sensor - beyond EMR.

Digital Interfaces RS422

8. Digital Interfaces RS422

8.1 Preliminary Remarks

The interface RS422 has a maximum baud rate of 1 MBaud. The factory-set baud rate is 921.6 kBaud. The maximum measuring rate is 2 kHz.

Data format: Measurement values in binary format, commands as an ASCII string.

Interface parameter: 8 Data bits, no parity, one stop bit (8N1).

i

Disconnect or connect the D-sub connection between RS422 and USB converter when the sensor is disconnected from power supply only.

8.2 Measurement Data Format

16

1 or

18 bits are transmitted per output value, see Chap. 7.5.2

. An output value is divided into three bytes that differ in the two most significant bits. The transmission of additional output values is optional.

Output value 1 / additional:

Output sequence: L-Byte, M-Byte, H-Byte.

1, 3) Error values are coded with 18 Bit.

2) Bit 7 in the H byte is set to 0 for the last output value. This simultaneously represents the identifier of a new block. With all previous output values in the same block, the 7th is in the H byte 1. Depending on the measuring rate, baud rate and output data rate output all data can be output in one block. If data output is not possible, a run-time error will be output. Use the command GETOUTINFO_RS422 to query for data selection and output sequence.

optoNCDT 1320 Page 76

Digital Interfaces RS422

8.3 Conversion of the Binary Data Format

For conversion purposes the H-Byte, M-Byte and L-Byte must be identified on the basis of the two first bits

(flag bits), the flag bits deleted and the remaining bits compiled into a 16 or 18 bit data word.

Result of conversion:

D17 D16 D15 D14 D13 D12 D11 D10 D9 D8 D7 D6 D5 D4 D3 D2 D1 D0

Conversion must be done in the application program. D16 and D17 are among others used for interpretation of error codes or e.g. for the measurement counter. i

The sensor continues to deliver measurement values to the RS422 output even while communicating with the sensor.

For the data transmission with a PC the MICRO-EPSILON IF2001/USB is suitable. The IF2001/USB combines the three bytes for the data word and saves them in the FIFO. The 18 bits are used for measurement values and error values. For further information, please refer to the descriptions of the IF2001/USB interface card and associated MEDAQlib driver program.

You will find the latest program routine at: www.micro-epsilon.com/link/software/medaqlip .

Cleaning

9. Cleaning

Cleaning of the protective screens is recommended periodically.

Dry Cleaning

Therefore an optics anti-static brush is suitable or bleeding the screen with dehumidified, clean and oil-free compressed air.

Wet Cleaning

For cleaning the protective screen use a clean, soft, lint-free cloth or lens cleaning paper with pure alcohol

(isopropyl).

Never use standard glass cleaner or other cleaning agents.

Appendix| ASCII Communication with Sensor

A 3 ASCII Communication with Sensor

A 3.1 General

The ASCII commands can be sent to the sensor via the RS422 interface. All commands, inputs and error messages are effected in English.

One command always consists of a command name and zero or several parameters, which are separated by blanks and are completed with LF. If blanks are used in parameters, the parameter must be set in quotation marks.

Example: Switch on the output via RS422

OUTPUT RS422

Advice: must include LF, but may also be CR LF.

Declaration: LF Line feed (line feed, hex 0A)

CR Carriage return (carriage return, hex 0D)

Enter (depending on the system System hex 0A or hex 0D0A)

The currently set parameter value is returned, if a command is activated without parameters.

The input formats are:

<Command name> <Parameter1> [<Parameter2> […]]

<Command name> <Parameter1> <Parameter2> ... <Parameter...> or a combination thereof.

Parameters in []-brackets are optional and require the input of the parameter standing in front. Sequent parameters without []-brackets are to input compulsory, that is, it must not be omitted a parameter.

Alternative inputs of parameter values are displayed separately by „|“, for example the values „a“, „b“ or „c“ can be set for “a|b|c“. Parameter values in <> brackets are selectable from a value range.

Declarations on format:

„a | b“

„ P1 P2“

Value of the parameter can be set to the value “a“ or “b“.

It requires that both parameters “P1“ and “P2“ are set.

optoNCDT 1320 Page 83

Appendix| ASCII Communication with Sensor

„<a>“ The value of the parameter lies in a value range of “... to …“, see parameter description.

Parameter values without peak brackets can only assume discrete values, see parameter description.

Parantheses are to be understood as a grouping, that is, for a better articulation „P1 P2 | P3“ is written as

„(P1 P2)|P3“.

Example without []:

„PASSWD <Old password> <New password> <New password>“

- To change the password, all three parameters are to be input.

The output format is:

<Command name> <Parameter1> [<Parameter2> […]]

The reply can be used again as command for the parameter setting without changes. Optional parameters are only returned, if the returning is necessary. For example, the activated output values are returned by command Data selection additional values. After processing a command always a return and a prompt (“ -> “) is returned. In the case of an error an error message is before the prompt, that begins with „E xxx “, where xxx is a unique error number. Also warnings („W xxx “) can be output instead of error messages.

These are analogous to the error messages. In case of warnings the command is executed.

The replies to the commands GETINFO and PRINT are useful for support requests to the sensor, because they contain sensor settings.

A 3.4.4 Measurement Value Processing

A 3.4.4.1 MASTERMV, Mastering / Zeroing

MASTERMV NONE|MASTER <MV>

- NONE: completes mastering

- MASTER: sets the current measurement value as a master value

- MV: master value in millimeters; MV = (0 ... 2) * measuring range, i.e. master value must be within measuring range

In case of master value is 0, the mastering has the same functionality as the zeroing. The parameter MV always operates independently from an input as zeroing during mastering the analog output.

The master command awaits the next measurement value, a maximum of 2 seconds, and masters it. If no measurement value is received within this time, for example, by external triggering, the command returns with the error “E220 Timeout“.

The master value is processed with six decimal places.

Note that the output value is limited to 18 bits.

A 3.5 Data Output

A 3.5.1 OUTPUT, Selection of Measurement Value Output

OUTPUT NONE|RS422|ANALOG

- NONE: no measurement value

- RS422: output of measurement value via RS422

- ANALOG: analog output of measurement values

A 3.5.2 OUTHOLD, Error Processing

OUTHOLD NONE|INFINITE|<n>

Setting the behavior of the measurement value output in case of error.

- NONE: no holding of the last measurement value, output of error value

- INFINITE: infinite holding of the last measurement value

- <n>: holding of the last measurement value on the number of measurement cycles; then an error value is output, n = (1 ... 1024) optoNCDT 1320 Page 98
