Functional Principle, Technical Data 3.1 Short Description The optoNCDT 1900 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. MR SMR 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.

New algorithms generate stable measurement results even on demanding surfaces where changing reflections occur. Furthermore, these new algorithms compensate for ambient light up to 50,000 lux. Therefore, this is the sensor with the highest resistance to ambient light in its class which can even be used in strongly illuminated environments. optoNCDT 1900 Page 15 Functional Principle, Technical Data 3.3 Technical Data Model 10 25 50 Measuring range ILD1900- 10 mm 25 mm 50 mm Start of measuring range 20 mm 25 mm 40 mm Midrange 25 mm 37.5 mm 65 mm End of measuring range 30 mm 50 mm 90 mm Continuously adjustable between 0.25 ... 10 kHz adjustable in 7 steps: 10 kHz / 8 kHz / 4 kHz / 2 kHz / 1.0 kHz / 500 Hz / 250 Hz ≤ ±2 µm ≤ ±5 µm ≤ ±10 µm Measuring rate 1 Linearity 2 Repeatability ≤± 0.02 % FSO 3 Temperature stability < 0.4 µm 4 SMR Spot diameter (± 10 %) 5 MMR EMR smallest Ø Light source Laser safety class Permissible ambient light Power supply Control inputs Digital interface Analog output optoNCDT 1900 < 0.8 µm < 1.6 µm ±0.005 % FSO/K 115 x 150 µm 200 x 265 µm 220 x 300 µm 60 x 65 µm 70 x 75 µm 95 x 110 µm 120 x 140 µm 60 x 65 µm bei 25 mm 220 x 260 µm 65 x 70 µm bei 35 mm Semiconductor laser < 1 mW, 670 nm (red) 260 x 300 µm 85 x 90 µm bei 55 mm Class 2 according to IEC 60825-1 : 2014 50,000 lx 11 ... 30 V DC, 24 V / P < 3 W 1 x HTL/TTL Multifunction input Trigger in / slave in / zero setting / mastering / teach 1x RS422 synchronization input (trigger in, sync in, master/slave, master/slave alternating) RS422 / 18 bit, PROFINET 6, EtherNet/IP 6 4 ... 20 mA / 0 ... 5 V / 0 ... 10 V (16 bit; freely scalable within the measuring range) Page 16 Functional Principle, Technical Data Model ILD1900- Digital output 25 Connection operation storage possible for simultaneous or alternating measurements integrated cable with 3 m length, open ends, min. bending radius 30 mm fixed mounted; or 0.3 m pigtail with 17-pol.

Installation 5.1 Instructions for Installation 5.1.1 Reflection Factor of the Target Surface In principle the sensor evaluates the diffuse part of the reflected laser light. Laser beam Laser beam Laser beam 2 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 maximum exposure time is dependent on the measuring rate and can only be increased by reducing the sensor’s measuring rate. optoNCDT 1900 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 1900 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 or switch on the background suppression function. 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 heat 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. optoNCDT 1900 Page 20 Installation 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. Min. Max. 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. optoNCDT 1900 Page 21 Installation 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. optoNCDT Y-axis X-axis Angle Fig. 6 Measurement errors through tilting with diffuse reflection optoNCDT 1900 Page 22 Installation 5.1.3 Optimizing the Measuring Accuracy Color strips Direction of movement In case of rolled or polished metals that are moved past the sensor the sensor plane must be arranged in the direction of the rolling or grinding marks. The same arrangement must be used for color strips. state output Grinding or rolling marks Fig. 7 Sensor arrangement in case of ground or striped surfaces In case of bore holes, blind holes and edges in the surface of moving targets the sensor must be arranged in such a way that the edges do not obscure the laser spot. correct optoNCDT incorrect (Shadow) Fig. 8 Sensor arrangement for holes and ridges optoNCDT 1900 Page 23 Installation 5.2 Mounting, Dimensions 5.2.1 General The optoNCDT 1900 sensor is an optical system for measurements with micrometer accuracy. The laser beam must be directed perpendicularly onto the surface of the target. i Make sure it is handled carefully when installing and operating. Mount the sensor only to the existing holes on a flat surface. Clamps of any kind are not permitted. Do not exceed torques. The bearing surfaces surrounding the fastening holes (through-holes) are slightly raised Fig. 9 Sensor mounting with diffuse reflection 5.2.2 Attachment Depending on the installation position, it is recommended to define the sensor position using centering elements and fitting bores. The cylindrical counterbore ø6H7 is intended for the position-defining centering elements. This allows for the sensor to be mounted in a reproducible and exchangeable way.

The fixed connected sensor cable is cable carriers suitable. Unused open cable ends must be insulated to protect against short circuits or malfunction of the sensor. MICRO-EPSILON recommends to use the cable carriers suitable standard connection cable PC1900 of the optional accessories, see Chap. A 1. Mount the cable connector if you use a cable carriers suitable sensor cable PC1900. Avoid excessive pulling to the cables. Provide strain relieves near the connectors when cables > 5 m are vertically free hanging. Do not twist the connectors in opposite directions when connected. 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. optoNCDT 1900 Page 35 Operation 6. Operation 6.1 Getting Ready for Operation Install and assemble the optoNCDT 1900 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 3 is connected with Pin 14, see Chap. 5.4.4. Once the power supply 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 3 seconds. Within this period, only the command reset or the bootloader is executed via the Select key. For 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. optoNCDT 1900 Page 36 Operation 6.2 Operation via Web Interface 6.2.1 Preconditions In the sensor a webserver is implemented. The web interface contains among other things the current settings of the sensor and the periphery. The operation is only possible as long as an RS422 connection to the sensor exists.

The masked range can be limited on request and is additionally limited by means of a light blue shading on the right and on the left. The remaining peaks in the resulting range are used for evaluation. optoNCDT 1900 Page 44 Operation 8 Scaling of the x-axis: you can enlarge (zoom) the overall signal by means of the left slider during ongoing measurement. If the diagram is stopped, you can also use the right slider.

By displaying the video signal, you can detect effect of the adjustable measurement task (target material), choice of peak and possible interfering signals by means of reflections. There is no linear relationship between the position of the peaks in the video signal and the output measurement value. 6.3 Parametrization via ASCII Commands As an added feature you can parametrize the sensor via an ASCII interface, physically the RS422. This requires, that the sensor must be connected either to a serial RS422 interface via a suitable interface converter, see Chap. A 1, or a plug-in-card to a PC / PLC. Pay attention in the programs used to the correct RS422 default setting. Once connected, you can transmit the commands via the terminal to the sensor, see Chap. A 4. 6.4 Timing, Measurement Value Flux The sensor requires four cycles for measurement and calculation without triggering: Each cycle takes 100 μs at a measuring rate of 10 kHz. The measured value N is available at the output after four cycles. The delay between acquisition and output is therefore 400 µs. As the processing in the cycles occurs parallel, after another 100 µs, the next measured value (N+1) is output. optoNCDT 1900 Page 45 Operation 6.5 Menu Structure, Operation via Membrane Keys Initialization The parameters interface and key function can be changed during function the initialization sequence only.

Value Fields with dark border require entry of a value. Page 49 Setting Sensor Parameters 7.4 Synchronization 7.4.1 Synchronization via Sync +/- Connections If two sensors measure against the same target, the sensors can be synchronized. The optoNCDT 1900 distinguishes between two types of synchronization. Type Used for Simultaneous Both sensors measure Measurement of differences (thickness, difference in height) on opaque objects. Here, Sensynchronization in the same cycle sor 1 must be programmed as the “Master“ and Sensor 2 as the “Slave“, see Chap. 7.3. Alternating Both sensors measure synchronization alternatively Output rate ≤ measuring rate / 2 Thickness measurements on translucent objects or measurements of difference on closely spaced measurement points. The alternat-ing synchronization requires that the lasers are switched on and off alternately so that the two sensors do not interfere with each other optically. Therefor one sensor is to program as “Master alternating“ and one as “Slave alternating“. There can be only one master to be connected to a slave.

Select the required measuring rate. Measuring rate 250 Hz / 500 Hz / 1 kHz / 2 kHz / 4 kHz / 8 kHz / 10 kHz Free measuring rate Value Use a high measuring rate for bright and mat measurement objects. Use a low measuring rate for dark or shiny measurement objects (e.g. black painted surfaces) to improve the measurement result. At a maximum measuring rate of 10 kHz, the CMOS element is exposed 10,000 times per second. The lower the measuring rate, the longer the maximum exposure time. The measuring rate is factory set to 4 kHz. Grey shaded fields require a selection. optoNCDT 1900 Value Fields with dark border require entry of a value. Page 53 Setting Sensor Parameters 7.5.4 Triggering 7.5.4.1 General The value input and output on the optoNCDT 1900 can be controlled through an external electrical trigger signal or commands. Both analog and digital outputs are affected. The measured value to the trigger point is output delayed, see Chap. 6.4. -- Triggering does not influence the preset measuring rate or the timing so that 4 cycles + 1 cycle (jitter) are between the trigger event (level change) and the output reaction -- Micro-Epsilon does not recommend any data reduction e.g. by subsampling when the trigger is used. -- The multi-function or synchronization inputs are used as external trigger inputs, see Chap. 5.4.6. -- Factory settings: no triggering, the sensor starts transmitting data output as soon as it is switched on. -- “Trigger in” pulse duration is at least 50 μs. The triggering of the measured value recording and output have the same timing.

UI t W t A0 t D0 t Fig. 32 Trigger edge HL (above) with analog output A0 and digital output signal D0 (below). Software triggering. Data recording is caused by the TRIGGERSW SET command. The sensor outputs the previously set number of measured values or initiates a continuous measured value output after the trigger event. Measurement value output can also be stopped via a command. optoNCDT 1900 Page 55 Setting Sensor Parameters 7.5.4.2 Triggering Data Recording The data recording trigger processes measurements which are recorded from the trigger event. Previously acquired measurement values are rejected. The record triggering therefore directly influences the subsequent processing of measured values. In particular, the average calculation only includes values measured from the trigger event. Activating the data recording trigger deactivates the data output trigger. 7.5.4.3 Triggering Data Output Measurement values are calculated continuously and independently of the trigger event. A trigger event simply triggers the value output via a digital or an analog interface. Therefore, any values measured immediately before the trigger event are included in calculating mean values (averages). Activating the data recording trigger deactivates the data recording trigger. optoNCDT 1900 Page 56 Setting Sensor Parameters 7.5.5 Masking the Evaluation Range, ROI Masking limits the evaluating range (ROI - Region of Interest) for the distance calculation in the video signal. This function is used in order to e.g. suppress interfering reflections or ambient light. Masked area Measuring range Fig. 33 Light blue areas limit the evaluation range The exposure control optimizes the peaks in the evaluation range. Therefore, small peaks can be optimally adjusted when a high interference peak is outside the evaluation range. optoNCDT 1900 Page 57 Setting Sensor Parameters 7.5.6 Exposure Mode Automatic mode Standard / Intelligent control / Background suppression 95 Intensity [%] Exposure mode 50 0 0 50 Range [%] 100 Standard: the sensor determines the optimal exposure time in order to achieve the highest possible signal intensity Intelligent control: the intelligent control algorithm is beneficial when measuring moving objects or material transitions. Background suppression: suppresses interferences caused by ambient light which greatly increases the sensor‘s ambient light tolerance. This reduces the sensor‘s output rate by half. Manual mode Grey shaded fields require a selection. optoNCDT 1900 Exposure time in µs Value Value In the manual mode, when the video signal is displayed, the user determines the exposure time Vary the exposure time in order to achieve a signal quality up to a maximum of 95 %.

Error handling Digital output, no value The analog output supplies 3 mA resp. 5.2 / 10.2 V instead of measurement value. The RS422 interface outputs an error value. Hold last value infinite Analog output and RS422 interface stop at the last valid value. Hold last value 1 ... 1024 Value If no valid reading can be obtained, an error is issued. Should this be a problem for processing, the last valid value can be hold for a certain period of time, and will be issued repeatedly. After this period has expired, an error value is output. 1) Amount of measurement cycles which output the last valid measurement. Then an error value is output.

The function Averaging 1 is done before Averaging 2. Averaging Inactive Measurement values are not averaged. Moving N values 2 / 4 / 8 ... 4096 Value Recursive N values 2 ... 32000 Value Median N values 3/5/7/9 Value Indication of averaging mode. The averaging number N indicates the number of consecutive measurement values to be averaged in the sensor. Measurement averaging is performed after the distance values have been calculated, and before they are issued through the relevant interfaces. Averaging - improves the resolution, - allows masking individual interference points, and - ‘smoothes’ the reading. Linearity is not affected by averaging. The average values are continuously recalculated with each measurement. The desired averaging depth is only achieved after the number of recorded measurement values corresponds at least to the averaging depth. Grey shaded fields require a selection. optoNCDT 1900 Value Fields with dark border require entry of a value. Page 60 Setting Sensor Parameters i The defined type of average value and the averaging number must be stored in the sensor to ensure they are hold after it is switched off. Averaging has no effect on the measuring rate or data rate in case of digital measurement value output. The averaging numbers can also be programmed via the digital interfaces. The optoNCDT 1900 sensor is delivered with “Median 9” as factory settings, i.e. median averaging over 9 measurement values. Depending on the type of average and the number of averaged values, different transition response times result thereof, see Chap. 6.4. 7.6.2.2 Moving average The definable number N for successive measurements (window width) is used to calculate the arithmetic average Mmov according to the following formula: MV N MV (k) M mov = k=1 N Measurement value, N Averaging number, k Running index Mmov Averaging value respectively output value Methods: Each new measured value is added, and the first (oldest) value is removed from the averaging (from the window). This produces short response times for measurement jumps. Example: N = 4 ... 0, 1, 2, 2, 1, 3 2, 2, 1, 3 = Mmov (n) 4 ... 1, 2, 2, 1, 3, 4 2, 1, 3, 4 = Mmov (n+1) 4 Measurement values Output value Special features: Moving average in the optoNCDT 1900 allows only potentials of 2 for N. Range of values for averaging number N is 1 / 2 / 4 / 8 ... 4096. optoNCDT 1900 Page 61 Setting Sensor Parameters 7.6.2.3 Recursive average Formula: Mrek (n) = MV(n) + (N-1) x Mrek (n-1) N Methods: MV Measurement value, N Averaging number, n Measurement value index Mrek Averaging value respectively output value The weighted value of each new measured value MV(n) is added to the sum of the previous average values Mrec (n-1). Special features: Recursive averaging allows for very strong smoothing of the measurements, however it requires long response times for measurement jumps. The recursive average value shows low-pass behavior. Range of values for the averaging number N is 1 ... 32000. 7.6.2.4 Median A median value is formed from a preselected number of measurements. Methods: The incoming measured values (3, 5, 7 or 9 measurement values) are also sorted again after each measurement. Then, the average value is provided as the median value. 3, 5, 7 or 9 measured values are taken into account for the calculation of the median, i.e. there is no median 1. Special features: This averaging type suppresses individual interference pulses. However, smoothing of the measurement curves is not very strong. Example: average value from five readings =3 ... 0 1 2 4 5 1 3 Sorted measurement values: 1 2 3 4 5 Median ... 1 2 4 5 1 3 5 Sorted measurement values: 1 3 4 5 5 Median (n+1) = 4 optoNCDT 1900 (n) Page 62 Setting Sensor Parameters 7.6.3 Output Trigger Details can be found in Triggering, see Chap. 7.5.4. 7.6.4 Data Reduction, Output Data Rate Data reduction Value Indicates the sensor which data is to be excluded from output, thus the data amount to be transmitted is reduced. Reduction relates to RS422 / Analog / Chart Interfaces to be used for undersampling are to be selected via the checkbox. You can reduce the measurement output in the sensor if you set the output of every nth measurement value in the web interface or by command. Data reduction causes only every nth measured value to be output. The other measurement values are rejected. The reduction value n can range from 1 (each measurement value) to 3,000,000. This allows you to adjust slower processes, such as a PLC, to the fast sensor without having to reduce the measuring rate.

Digital Interfaces RS422 8.1 Preliminary Remarks The interface RS422 has a maximum baud rate of 4 MBaud. The factory-set baud rate is 921.6 kBaud. 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 18 bits are transmitted per output value, see Chap. 7.7.2. 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: L-Byte 0 0 D5 D4 D3 D2 D1 D0 M-Byte 0 1 D11 D10 D9 D8 D7 D6 H-Byte 1 0 D17 D16 D15 D14 D13 D12 1 Output sequence: L-Byte, M-Byte, H-Byte. 1) 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 overloaded, an error value is transmitted within the distance value. Use the command GETOUTINFO_RS422 to query for data selection and output sequence. optoNCDT 1900 Page 83 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 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. 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 IF2008/PCIE PCI BUS interface card is suitable. This can be connected to the sensor via the PC1900-x/IF2008 interface cable, which is also available as an option. The IF2008/PCIE 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. As standard, the IF2008 interface card is suitable for connecting two or (via a Y intermediate cable available as an option) up to four sensors plus two additional incremental encoders. For further information, please refer to the descriptions of the IF2008/PCIE interface card and associated MEDAQlib driver program. You will find the latest program routine at: www.micro-epsilon.com/link/software/medaqlib. optoNCDT 1900 Page 84 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. 10.

Reset to factory setting: Press the Select key after having switched on the sensor while the two LEDs light up „red - yellow - green“. Hold the key pressed. After 10 seconds, the Status LED starts flashing quickly. If you release the key while it flashes quickly, the sensor is reset to factory settings. If you hold the key pressed for longer than 15 seconds, the sensor is not reset to factory settings. If the Select key is kept pressed when switching on the sensor (or with a reset), the sensor switches to the Bootloader mode. optoNCDT 1900 Seite 89 Appendix | ASCII Communication with Sensor A3 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 CR Line feed (line feed, hex 0A) Carriage return (carriage return, hex 0D) Enter (depending on the 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. optoNCDT 1900 Seite 90 Appendix | ASCII Communication with Sensor Declarations on format: „a | b“ Value of the parameter can be set to the value “a“ or “b“. „ P1 P2“ It requires that both parameters “P1“ and “P2“ are set. „ P1 [P2 [P3]]“ The parameters “P1“, “P2“ and “P3“ can be set, whereby “P2“ may only be set, if “P1“ is set and “P3“ only if “P1“ and “P2“ are set. „<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 „Exxx“, where xxx is a unique error number. Also warnings („Wxxx“) 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. optoNCDT 1900 Seite 91 Appendix | ASCII Communication with Sensor A 3.2 Overview Commands Group Chapter General Chap.
