Functional Principle, Technical Data
3. Functional Principle, Technical Data
The optoNCDT ILR 1191 is a laser-based distance sensor for non-contact and precise distance and displacement measurements from 0.5 m up to 3.000 m. The sensor is designed for very large measuring ranges, with and without reflector. Due to the very high measuring rate of the sensor, moving objects can be measured easily. The sensor operates according to the laser pulse runtime principle and is therefore particularly well suited to applications with large distances. Commissioning of the sensor is straightforward due to a variety of interfaces and easy mounting options. The optoNCDT ILR 1191 is fitted with an integrated heater for outdoor use. A pilot laser is also integrated for mounting and adjustment.
The sensor measures distances to moving and static targets:
- with measuring range from 0.5 m up to 300 m on diffuse reflective surfaces with 90 % reflectivity,
- with measuring range from 300 m up to 3.000 m on reflector surfaces, for example Scotchlite series 3290,
The sensor is used for speed measurement from 0 m/s up to 100 m/s (at 0.5 m up to 700 m distance).

Fig. 2 Elements of a sensor
With the help of a visible red laser sighting point (pilot laser) a given target can be unequivocally identified.
The actual range of measurement depends on the reflectivity and the surface quality of a target being measured. The sensor is available with RS232 or RS422, depending on the customer’s request. Product manufacturing includes the installation of a requested configuration. Once installed, the interface cannot be replaced
Page 12
Functional Principle, Technical Data with another type.
The sensor contains two switching outputs and one external trigger input and trigger output (all of them parameterizable).
A distance measurement can be triggered:
- via RS232 interface or RS422 interface
- via Profibus DP-V0
- by an external source (in external trigger mode).

Installation and Mounting
The laser beam must be directed perpendicularly onto the surface of the target. In case of misalignment it is possible that the measurement results will not always be accurate. Measurements against tilted targets are possible but depend on the surface characteristics of the target.
For integration of the sensor, two different versions of mechanical attachment are available:
- Attachment to a lateral surface. The sensor provides three support pads, see Fig. 5
, reference 1, with mounting holes M4 x 6.
- Attachment to casing bottom. The sensor provides three support pads, see Fig. 5
, reference 2, with mounting holes M4 x 6.
The sensor will be aligned by a visible laser beam (pilot laser) with the target. To align the sensor, please
comply with the “Instructions for Operation“, see Chap. 9.

5.2 Reflector Mounting
The sensor measures distances to moving and static targets:
- in the range from 0.5 m up to 300 m for natural, diffuse reflecting surfaces with a reflectivity of 90 %,
- between 300 m and 3.000 m to a reflector (for example Scotchlite Engineer Grade type I, series 3290, from
3M)
, reference 6, supports the sensor alignment to a given target during commissioning. It qualifies as a class 2 (II) laser device and operates at 635 nm (red) in the visible range. The pilot laser

- With multi-value parameters, space (0x20) is used between each two values
- A parameterization command with new parameters triggers a response command with these parameters
- A parameterization command without new parameters triggers a response command with (most recent) parameters
- A parameterization command with parameters out of valid setting ranges triggers a response command with (most recent) parameters
- An unknown command and a faulty parameter format are quitted via “?” (0x3F)
The easiest way to start and parameterize the sensors is by using a PC with RS232 communication port and
a terminal program, see Chap. 11.
The communications protocol is available in ASCII format.

SSI Interface
7. SSI Interface
Read this chapter, if you work with a ILR 1191-300(03) sensor.
Optionally, the sensor can be equipped with an SSI data interface (SSI = Synchronous Serial Interface). At the request on a SSI clock generator a distance measurement cycle will start, sending related data which are present at the shift register bit-by-bit to a controller. Depending on the length and quality of selected data lines, actual transfer rates may range from 50 kHz to 1 MHz with 25 µs pause time between two bit sequences.
- The data length is 24 bits plus one validity bit.
- The format can be binary or gray-encoded.
- For parameter settings via the serial interface, the SCx command is available
SCx x=0...binary, 25 bit, 1 validity bit x=1...gray, 25 bit, 1 validity bit

8. Profibus Interface
Read this chapter, if you work with a ILR 1191-300(04) sensor.
8.1 ID Number
The sensor has been registered under ID number OAA2
HEX user organization, registered society).
with Profibus Nutzerorganisation e.V. (Profibus
8.2 Connection Requirements
The sensor may be connected to any kind of Profibus DP structure, the requirement being that the selected
Profibus DP master is capable of sending a parameterization telegram, and the master’s pertaining editing tool (typically, editing software) will support the representation of parameters that are contained in the respective device master file (GSD file).
The GSD file is named ILR90AA2.GSD. A GSD file includes the two files ILR 1191.dib and ILR 1191.bmp.
These are intended for representation of the sensor in the editing tool. For integration of these files, please consult the special editing tool documentation.
8.3 Slave Address
To facilitate multiple-participant bus communication, the Profibus slave address can be set in a range of
0 to 125. A desired address can be set via the Profibus, using the SSA command. For information on how to change the slave address via the editing tool, you should consult the special editing tool documentation. Address 4 is set in as-shipped state of the sensor.
The slave address is permanently maintained in the EEPROM. It will also be preserved in the event of a voltage failure.
Where more than one slave (ILR 1191) are to share a common Profibus, the various slaves must be connected one after the other and be assigned different addresses.
optoNCDT ILR 1191 Page 35
Profibus Interface
8.4 Bus Termination
For sensor operation, an external bus terminator must be installed. A voltage supply of 5 V required for the terminator is available at Profibus-OUT. This 5 V supply is electrically isolated from general voltage supply
(VCC) and rated for a current load up to 100 mA. The terminating resistor is available as an optional accessory item.
8.5 Baud Rate
The sensor has its own device for automatic detection of the following baud rates: 9.6 / 19.2 / 93.75 / 187.5 /
500 k baud and 1.5 / 3 / 6 / 12 Mbaud.
8.6 Segment Length
The maximum allowed segment length between to Profibus participants depends on the selected baud rate.
The following rules on segment lengths must be fulfilled:
Baud rate Segment length
9.6 ... 93.75 kBaud 1,200 m
187.5 kBaud
500 kBaud
1.5 MBaud
1,000 m
400 m
200 m
3 ... 12 MBaud 100 m
To comply with these segment rules, use of cable type A is strongly recommended.
Distinguishing features of cable type A are:
- Wave resistance 135 to 165 Ohm
- Capacitance per unit length ≤ 30 pf/m
- Loop resistance ≤ 110 Ohm/km
- Cable wire diameter
- Cable wire cross-section
> 0.64 mm
> 0.34 mm² optoNCDT ILR 1191 Page 36
Operation optoNCDT ILR 1191
9. Operation
Insert connector in main connection port and interface.
Install and firmly screw Profibus and SSI connectors.
Protect all cable ends, which you don‘t use, before you turn on the power supply. So you avoid short circuits.
The user is required to implement:
- the application-specific wiring,
- the application-specific parameterization of the Profibus, the slave address.
Turn-on the voltage supply for the sensor. The Status LED must light green.
Make sensor parameter settings via RS232/RS422.
Start the distance measurement.
Install the sensor using the pilot laser as part of preparative actions in the designated working site, oriented onto the target and keep it in a stable position. The target to be measured should preferentially have a homogeneous, white surface.
Lock the sensor.
The sensor provides a visible laser beam (pilot laser) for greater convenience in alignment. Its visibility is conditional on the amount of ambient light present and on the type of surface of the target to be measured.

Control Commands
10. Control Commands
The easiest way to trigger and parameterize the sensors is by using a PC with RS232 communication port
and a terminal program, see Chap. 11.
The communications protocol is available in ASCII format.
Before an operating session begins, desired parameter settings can be made in a smart selection procedure until the measuring module is optimally adapted to the particular measuring site conditions and the measuring job. All valid settings will be preserved on turning the sensor off. They can only be replaced with new value entries or changed back to their standard values by running an initialization routine.
Command entries are not case-sensitive. This means that small and capital lettering can be used for commands. Any command which is to be sent to the sensor must be terminated by a hexadecimal 0Dh (carriage return) character.
Where decimal digits are to be entered, they must be separated by period (2Eh).
For command parameter entries, one must distinguish between parameter settings and parameter queries.
Querying is achieved with a command in simple format, for example analog output: QA[Enter].
For parameter setting, a new value must be added after the command with no delimitation sign in between, for example: QA50 250[Enter].
With multi-value parameters, space (0x20) is used between each two values.
10.1 Identification
In response to an ID command, the sensor outputs its manufacturing data in this order: product type, firmware version, firmware data, firmware time, fabrication number, date of manufacture and time of manufacture.
Example:
ILR1191 1.1.16(R) 27.03.2007 11:31 060001 11.04.2007 08:56 optoNCDT ILR 1191 Page 38
Control Commands
10.2 Operation Modes i
The sign ESC (1Bh) finishes the data output. Now the sensor waits for a new command.
10.2.1 DM – Single Distance Measurement
The sensor performs exactly one measurement, on completion of which it will wait for next instructions.
The length of time, witch measurement requires depends on the number of the averaged measuring values, see parameter SA, and the preset measuring frequency, see parameter MF.
Example:
- Averaging of 5 measuring values, SA5
- Measuring frequency: 1 measurements per second, MF1
- Continuity of measurement = 5 seconds
10.2.2 DT – Continuous Distance Measurement
The sensor performs continuous distance measurement until halted by a special command
(RS232/RS422: Escape = 0x1B).
The output rate of measured values depends on the number of the averaged measuring values, see parameter SA, and the preset measuring frequency, see parameter MF.
Example:
- Averaging of 5 measuring values, SA5
- Measuring frequency: 50 measurements per second, MF50
- Output rate of measured values = 10 measuring values per second i
In the mode DT the analog output will be actualized with every new measuring value. In between the old value is kept.
optoNCDT ILR 1191 Page 39
Control Commands
10.2.3 DF – Single Distance Measurement with External Triggering
The sensor is be located in the mode DF. It will then perform exactly one measurement cycle on receipt of an external trigger signal and wait in DF mode for the next trigger event to arrive. This mode must be terminated with the help of a special command (RS232/RS422: Escape = 0x1B).
Apply the trigger event to the external trigger input, see Chap. 5.3.5
The interval between two single measurements depends on
- the number of the averaged measuring values, see parameter SA,
- the preset measuring frequency, see parameter MF, and
- and the preset trigger delay, see parameter TD.
10.2.4 VM – Single Speed Measurement
The sensor performs 25 single measurement cycles, on completion of which it will use the 25 single readings to calculate a resulting speed.
The length of time, which measurement requires, depends on
- the number of averaged measuring values, see parameter SA,
- the preset measuring frequency, see parameter MF.
Example:
- Averaging of 1 measuring value, SA1
- Measuring frequency: 50 measurements per second, MF50
- Continuity of measurement = about 0.5 seconds optoNCDT ILR 1191 Page 40
Control Commands optoNCDT ILR 1191
10.2.5 VT – Continuous Speed Measurement
The sensor performs continuous measurement in packages of 25 single measurement cycles. This measuring mode must be halted with a special command (RS232/RS422: Escape = 0x1B).
The time interval between single measurements depends on
- the number of averaged measuring values, see parameter SA,
- the preset measuring frequency, see parameter MF
Example:
- Averaging of 1 measuring value, SA1
- Measuring frequency : 50 measurements per second, MF50
- Output rate of measured values = 2 measuring values per second i
In the mode VT the analog output submits the distance information.
10.3 Parameter
- Parameter settings can be made via this serial interface.
- 0x0D as termination character will cause the command to be transmitted to the sensor.
- For commands with one parameter, the parameter can be defined either directly or separated by space
(0x20).
- For commands including several parameters, each two parameters must be separated by space (0x20).

Hyperterminal
11. Hyperterminal
You can receive data and configure the controller through the RS232 interface with the Windows HyperTerminal®. All you need is a free COM port (for example COM1) on your PC and the commands described in the foregoing chapters.
i
The RS232 interface are popular in industrial applications. Use an adequate USB TO RS232 converter, in the case of your PC/notebook is just equipped with USB interfaces.
Preparation Measuring
Connect your controller to a free COM port of the host computer.
Start the program HyperTerminal® (Menu Start > Programs > Accessory > Communication > Hyper-
Terminal)
Type in the name of the connection and click on the “OK“ button.
