TECHNICAL REFERENCE MANUAL

2 Application examples

Since the configuration of the DLS-C(H)/FLS-C(H) is very flexible the device is usable in various situations. The following application examples give an idea of possible applications. Please visit www.dimetix.com for a detailed description of the mentioned application examples and check for additional application examples.

2.1 Serial interface RS-232 / RS-422

While the RS-232 should be used for the configuration of the device (See

3.1 Connection for configuration on page 8) the RS-422 is made for communication in industrial environment (See 3.3.1 Controlled mode on page 10 and 4.2.4 Serial connection on page 18). Fig. 2 shows the connection of multiple DLS-C(H)/FLS-C(H) devices to a Siemens S7 PLC. A detailed application note can be found on

www.dimetix.com.

For RS-422 connections use twisted pair cables only!.

2.2 Analog and digital output

Activate the stand-alone mode (3.3.2 Stand-alone mode on page 11) and the device is ready to use. It starts measuring after power on and updates the analog and digital output according to the configuration. See 9.3.4 and the following chapters for the configuration commands.

2.3 External display

If Display Mode is enabled, the DLS-C(H)/FLS-C(H) formats the measured distance as ASCII string, which is understood by External Displays with a serial interface. Since the DLS-C(H)/FLS-C(H) transfers this formatted string automatically on the serial interface after completing a measurement. Measurement results can be displayed on an external display without an additional controller. Check www.dimetix.com for a detailed application note.

2.4 External trigger

The DLS-C(H)/FLS-C(H) includes the option of triggering measurements with an external switch or push button on Digital Input 1 (DI 1). Using the Digital Input DI 1 disables the Digital Output DO 1.

TECHNICAL REFERENCE MANUAL

2.5 SSI connection

Set the FLS-C(H) in stand-alone mode (3.3.2 Stand-alone mode on page 11) and connect it to a SSI master as shown in Fig. 6. The measured distances are immediately available at the SSI output. See 9.3.10 Interface 2 configuration (RS422 / SSI) on page 39 for the detailed command description.

Never connect the SSI master before the FLS-C(H) interface 2 is configured as SSI interface.

2.6 Positioning

The figure on the left shows a typical positioning application. In this application the SSI interface of the FLS-C(H) is directly connected to a position input of a motor drive. The drive controls the motor In such a way, that the sledge moves to the position given as set point by the PLC. The encoder is used for security reasons to double check the movement by the Drive. In this applications the FLS-C(H) uses the SSI interface (4.2.6 SSI connection on page 19) and the moving target characteristic (3.4.2 Moving target characteristic on page 13. Please check on www.dimetix.com for detailed application notes.

3 Device overview and setup

We recommend that you carry out the configuration steps in an office before mounting the device, especially if you are not familiar with the DLS-C(H)/FLS-C(H).

Configure the outputs first and second do the configuration of the operation mode. The following sections describe the configuration steps and give an example.

3.1 Connection for configuration

To be able to configure the DLS-C(H)/FLS-C(H), it must be powered and connected to a PC. Figure 8 shows the necessary connections. On the PC, any terminal program can be used to communicate with the module. A configuration utility is also available on the web page

TECHNICAL REFERENCE MANUAL

3.2 Output interfaces

The DLS-C(H)/FLS-C(H) contains different interfaces. Measurement results and errors are signaled at the outputs as described below.

RS-232

The RS-232 is meant for the configuration of the device, however measurement can also be taken using the RS-232 interface. Measurement results and/or error codes are sent corresponding to the command description. To use this interface host system is needed as described in 3.3.1 Controlled mode on page 10.

RS-422

The RS-422 operates like the RS-232, but it is an industrial interface and therefore not only usable for configuration but also for controlled measurement as described in 3.3.1 Controlled mode on page 10. The RS-422 can not be used simultaneous with the SSI interface since it uses the same signal lines.

SSI Output

The SSI Interface is only implemented in the FLS type. The SSI interface is updated after each successful measurement as well as after an error occurs. If the interface is activated, it is updated in all operation modes. Binary and Gray code as well as error signalization is supported. (See 4.2.6 SSI connection on page 19)

Analog Output

The analog output is updated in controlled and stand-alone mode. It is configurable and works with two ranges:

- 0..20mA

- 4..20mA

Digital Outputs

Three digital outputs are included in the DLS-C(H)/FLS-C(H). Two of them are programmable, while the third is used to signal an error state of the device. The digital outputs are updated in all operation modes.

3.2.1 Output configuration example

After connecting the DLS-C(H)/FLS-C(H), the following steps are necessary to configure the output behavior.

TECHNICAL REFERENCE MANUAL

3.3 Operation modes

The first decision to be taken is the type of operating mode that will be used to perform distance measurements. While the controlled mode provides maximum flexibility and accuracy, it is often not suitable for integration into existing drives, PLCs or analog environments. In such cases the Stand-alone mode might be preferred.

controlled mode stand-alone mode

Auto start Manual start

The measurement is controlled by a host with commands such as

- sNg

- sNh

- sNuf

The measurement starts after power on. This must be configured with the command

- sNA

- sNuA

After configuring the DO1 as DI1, the measurement can be triggered by an external signal. Use the following command

- sNDI

See 9.2 Operation commands starting on page 30 See 9.3.3 Set auto start

configuration (sNA) on page 35

See 9.3.8 Configure digital input (sNDI1) on page 38

After each measurement all outputs are updated corresponding to the configuration (See 9.3 Configuration commands on page 33).

3.3.1 Controlled mode

In controlled mode, each operation of a DLS-C(H)/FLS-C(H) is triggered by a command sent from a host system over a serial line. While a single device can be connected to the host system using the RS-232 interface, up to 10 devices can be connected to a single serial RS-422 line. The related command set is described in Chapter 9 on page 29.

3.3.1.1 Configuration

After connecting the module, the steps below are necessary to configure the DLS-C(H)/FLS-C(H) for the controlled interface mode.

No. Action Comment Command

on page 28) using the reset button (6.2 Reset switch on page 24). Please note that the ID switch must be reset manually.

3.3.1.2 Host software

Host software is required for operation of the DLS-C(H)/FLS-C(H) in controlled mode. When connecting multiple devices to a single serial line (RS-422), strict Master-Slave communication must be implemented (DLS-C(H)/FLS-C(H) operates as slave). For software sample-code or application-notes please consult our web site www.dimetix.com.

Careful testing of the host software together with the devices prior to installation is strongly recommended.

3.4 Measuring characteristics

Multiple measuring characteristics are available in the FLS-C measuring devices to meet different requirements for various applications. With these measuring characteristics measuring rate and accuracy can be optimized for special requirements.

The FLS-C measuring device at factory settings has an accuracy of ±1 mm (FLS-C(H) 10) respectively ±3 mm (FLS-C(H) 30) at 2σ. Measuring rate depends on environmental conditions such as target surface, distance, background light (e.g. sun light), etc. Good environmental conditions increase measuring rate (e.g. white target surface or orange reflective target plate and dark environment).

TECHNICAL REFERENCE MANUAL

3.4.2 Moving target characteristic

For continuous movements of a target which typically appears in positioning applications like automatic warehouses there is a special measurement characteristic built into the FLS-C (H) called “Moving target”(See 2.6 Positioning on page 7 for a sample application)

To operate the FLS-C(H) in this measurement characteristic successfully, distance jumps must not occur. The laser beam must always hit the target.

This measurement characteristic combines a fast measurement rate with the unique accuracy of the FLS-C(H). The measurement rate is fixed and does not change during operation. For RS-232, RS-422, analog and digital outputs, the output rate is 250Hz. The SSI interface can return reliable measurement data at up to 500Hz read out rate corresponding to the clock received from the master.

When measuring to a stopped target, the resulting distance will stay at a single value, it does not occur any deviation of the distance. This is necessary if the sensor is used for positioning in closed looped applications.

An optimized error handling suppresses short errors, that may occur by a short break of the laser beam. In addition an over speed detector (>10m/s) detects improper situations, which results in an error. This ensures robust operation in positioning applications.

The behavior of the device in case of a severe error can be defined by the operator (See 3.4.3 Error behavior on page 14).

For a description of the configuration command see 9.3.2 Measuring characteristic configuration (sNuc) on page 34.

3.4.3 Error behavior

The device has different error behaviors depending on the measuring characteristics and on the start operation.

3.4.3.1 A - Behavior

In case the device detects an error, this error is signalized at the outputs. On the serial and SSI output the error code will be visible depending on the configuration. The error will be visible at the output until the device performs a successful measurement and outputs the new distance value or the device will be reset by command (sNc) or by a power cycle.

3.4.3.2 B – Behavior (in moving target characteristic)

This error behavior is only relevant when using the moving target measurement characteristic.

Situation

Temporary error The temporary error is converted into a

permanent error. This error must be reset as described below.

The temporary error disappears as soon as the error condition is cleared (a successful measurement is done).

Permanent error The permanent error must be reset as described

below.

The permanent error must be reset as described below.

The error reset function depending on the start condition. The following diagram shows the error reset for the different start configurations.

Stand-alone mode: Auto start configuration

(3.3.2.1 Auto start configuration on page 11)

In this operation the measurement starts automatically at power on. A signalized error is reset automatically after 5 seconds. The reset is done by an automatic restart of the device. This restart maximal takes about 4 seconds.

Stand-alone mode: Manual start configuration

(3.3.2.2 Manual start configuration on page 11)

In this operation the measurement is started with a digital input. In case of an error, the reset of a signalized error is done by restarting the measurement with the digital input.

With the offset and gain the result of the user commands (See 9.4 Special user operation commands on page 43) are changed only. Analog, Digital and SSI output values are not affected.

3.5.2 Output format

The DLS-C(H)/FLS-C(H) is able to format the output value on the serial interface (RS-232/RS-422) in order to fit it to an ASCII display. By the command sNuo the length of the output value can be defined as well as the position of the decimal point. This command in combination with a gain and offset allows the direct connection of an external display as described under 2.3 External display on page 6.

The command is described under 9.5.4 User output protocol (sNuo) on page 46

Distance Laser Sensor Page 15/53

TECHNICAL REFERENCE MANUAL

3.6 Output value filter

The DLS-C(H)/FLS-C(H) contains a filter for the measurement value, which can be activated and offers different configurations. This filter is available in the following Measuring characteristics (see 3.4 Measuring characteristics) on the DLS-C(H) and the FLS-C(H):

- Normal

- Fast

- Precise

- Natural Surface

- Timed

The output value filter is made of a moving average, a spike suppression as well as an error suppression filter. These filters are all configurable to offer most possible flexibility for the adaption of the DLS-C(H)/FLS-C(H) device to various applications.

This filter is inactive for the moving target characteristic.

3.6.1 Moving average filter

The moving average filter averages a specified number of measurements. Maximum 32 measurement values can be averaged. If a new measurement value is present, this value will be added to the filter values, while the last value will be removed. The sum of all measurement values divided by the size of the filter is transferred to all outputs.

3.6.2 Spike suppression filter

The spike suppression eliminates pairs of min max values inside the filter values (Number of filter values can be defined). Always the smallest and largest values are removed from the average calculation.

3.6.3 Error suppression filter

A maximum number of errors inside the filtered values can be suppressed. If the number of errors inside the filtered values is less as the specified value, no error is shown at the output

4 Installation

4.1 Mounting

4.1.1 Mounting of the device

Three M4 threaded holes in the bottom of the DLS-C(H)/FLS-C(H) make it easy to mount the device. Always obey all applicable safety regulations and never use the device outside the specifications stated under 5 Technical data on page 21.

4.1.2 Mounting for the reflective plate

Measuring to the reflective plate may generate erroneous measurements, if the reflective plate is mounted exactly at an angle of 90° to the laser beam. Therefore mount the reflective plate like shown in figure 13.

Avoid direct sunlight on the reflective plate to increase measurement performance.

4.1.3 Alignment of the laser beam

Alignment of the laser beam is often difficult when the target is far away, as the laser spot is not visible. An optional telescopic viewfinder and an alignment jig is available to simplify the alignment procedure. (See www.dimetix.com for additional accessories and further details).

4.1.4 Laser Life time consideration

since the life time of the laser is limited, operate the device in a way, that the laser is switched on only when necessary. The laser life time stated under 5 Technical data on page 21 relates to the time while the laser is on.

4.2 Device wiring

4.2.1 Power supply

For trouble-free operation use a separate power supply for the DLS-C(H)/FLS-C(H).

FLS-C, DLS-C: 9...30V, 0.5A DC FLS-CH, DLS-CH: 24...30V, 2.5A DC

4.2.2 Cable connection

A ferrite core must be fitted to the connecting cable. Use a ferrite core with an impedance of 150 Ω to 260 Ω at 25MHz and 640 Ω to 730

Ω at 100MHz. For example you can use KCF-65 from KE Kitagawa.

4.2.3 Shield and ground

The DLS-C(H)/FLS-C(H) contains two electrically isolated grounds, the general ground (GND) and the analog ground (AGND). GND and AGND are connected to the housing by a RC element. Please see figure 19.

TECHNICAL REFERENCE MANUAL

4.2.4 Serial connection

This connection is mainly used for the controlled mode or to configure the device.

RS-232

Only point-to-point communication is possible when using the RS-232 interface.

Never connect multiple DLS-C(H)/FLS-C(H)s on a RS-232 serial line

RS-422

It is possible to connect multiple devices on a single RS-422 line. To ensure proper operation, strict Master-Slave communication must be applied. It is important, that the Master has full control of the communication and never initiates a new communication before termination of the previous communication (answer from the DLS-C(H)/FLS-C(H) or timeout).

For RS-422 connections, use shielded twisted pair cables only! For detailed information following the RS-422 guidelines.

Ensure, that all DLS-C(H)/FLS-C(H)s are set to different ID numbers.

The RS-422 interface cannot be used simultaneous with the SSI interface.

5 Technical data

5.1 Measuring accuracy definition

The measuring accuracy corresponds to the ISO-recommendation ISO/R 1938-1971 with

a statistical confidence level of 95.4% (i.e. ± twice the standard deviation σ, refer to

diagram on the right). The typical measuring accuracy relates to average conditions for measuring. It is ±1.0mm for the FLS-C(H) 10, ±1.5mm for the DLS-C(H) 15 and ± 3.0mm for the DLS-C(H)/FLS-C(H) 30 valid in the tracking mode.

Maximum deviation may occur under unfavorable conditions such as bright sunlight or when measuring to poorly reflecting or very rough surfaces. Measuring accuracy may deteriorate by approximately ±0.02mm/m for distances above 30m.

The DLS-C(H)/FLS-C(H) does not compensate changes of atmospheric environment. These changes can influence the accuracy if measuring long distances (>150m) under conditions very different from 20°C, 60% relative humidity and 953 mbar air pressure. The influences of the atmospheric environment are described in

B.Edlen: “The Refractive Index of Air, Metrologia 2”, 71-80 (1966)

5.2 Measuring performance influences

The DLS-C(H)/FLS-C(H) is an optical instrument, whose operation is influenced by environmental conditions. Therefore, the measuring range achieved in use may vary. The following conditions may influence the measuring range:

Key Factors increasing range Factors reducing range

Target surface Bright and reflective surfaces such as the target plates

(See Accessories)

Matt and dark surfaces Green and blue surfaces

Airborne particles Clean air Dust, fog, heavy rainfall, heavy snowfall

Sunshine Darkness Bright sunshine on the target

The measurement range may be influenced by the configuration of the measurement characteristic. See 9.3.2 Measuring characteristic configuration (sNuc) on page 34.

The DLS-C(H)/FLS-C(H) does not compensate the influence of the atmospheric environment, which may be relevant when measuring long distances (e.g. > 150m). These effects are described in:

5.3 Prevention of erroneous measurements

5.3.1 Rough surfaces

On a rough surface (e.g. coarse plaster), measure against the center of the illuminated area. To avoid measuring to the bottom of gaps in the surface use a target plate (see accessories on www.dimetix.com) or board.

5.3.2 Transparent surfaces

To avoid measuring errors, do not measure against transparent surfaces such as colorless liquids (such as water) or (dust-free) glass. In case of unfamiliar materials and liquids, always carry out a trial measurement.



Erroneous measurements can occur when aiming through glass panes or if there are several objects in the line of sight.

5.3.3 Wet, smooth, or high-gloss surfaces

1 Aiming at an “acute“ angle deflects the laser beam. The DLS-C(H)/FLS-C(H) may receive a signal that is

too weak (error message 255) or it may measure the distance targeted by the deflected laser beam.

2 If aiming at a right angle, the DLS-C(H)/FLS-C(H) may receive a signal that is too strong (error message 256).

5.3.4 Inclined, round surfaces

Measurement is possible as long as there is enough target surface area for the laser spot. On irregular and round surfaces the arithmetic average of the illuminated surfaces will be measured.

5.3.5 Multiple reflections

Erroneous measurements may occur if the laser beam is reflected by other objects than the target. Avoid any reflective object along the measurement path.

5.3.6 Influence of sun light

Aiming directly to the sun or the sun is exactly behind the target could make it impossible to measure distances.

The stated errors include all possible errors as Temperature drift, linearity, surface color and measurement distance.

The best accuracy of ±1.5 mm for the DLS-C(H) 15 and ±1 mm for the FLS-C(H) 10 can only be achieved by using the digital interfaces (RS-232, RS-422 or SSI)

6.6 RS-232 serial interfaces

The RS-232 interface is used for device configuration. It is made to connect the sensor to a PC to do the configuration either by terminal program or by the UtilitySW (See 3.1 Connection for configuration on page 8).

If the Moving Target measurement characteristic is active, a measurement speed of 250Hz is only possible if the baud rate is set to 115200. Lower baud rates reduce the measurement speed

6.7 RS-422 serial interface

The RS-422 interface is made for industrial communication and therefore long cables (twisted pair) are supported. This interface is thought to use the DLS-C(H)/FLS-C(H) in controlled mode.

The RS-422 interface cannot be used simultaneous with the SSI interface.

If the Moving Target measurement characteristic is active, a measurement speed of 250Hz is only possible if the baud rate is set to 115200. Lower baud rates reduce the measurement speed

6.8.2 SSI Timing

Monoflop Time: Minimum time to detect the end of transmission. After tm, the data line goes to idle state and the slave starts

updating the internal value for the next transmission.

Pause time: Pause time between two consecutive clock sequences of the master.

The SSI is initially in the idle mode, where the data and clock lines stay HIGH 1 and the slave keeps updating its internal value. The transmission mode is evoked when the master initiates a sequence by pulling the clock line to low. Once, the slave receives the resulting falling edge 2 at the clock signal line, it automatically stops updating its internal value. With the first rising edge 3 of the clock line, the MSB of the sensor’s value is transmitted and with consequent rising edges, the data bits are sequentially transmitted. After the transmission of the complete data word 4 (e.g. LSB is transmitted) an additional last rising edge 5 of the clock sets the clock line to HIGH. The slave sets or leaves the data line to low and remains there for the time tm, to recognize the transfer timeout . If a falling edge of the clock signal (data-output request) is received within the time tm, the same data as before will be transmitted again (multiple transmission). If there were no clock pulses within time tm, the slave starts updating its internal value after setting the data line to HIGH (idle mode). This marks the end of a single transmission of a data word. Once the slave receives a clock signal at a time, tp (>=tm,) the updated position value is frozen and the transmission of the new value begins as described earlier.

9.3.2 Measuring characteristic configuration (sNuc)

Multiple measuring characteristic available in the FLS-C measuring devices meet different requirements for various applications. With these measuring characteristics measuring rate and accuracy can be optimized for special requirements.

While on factory settings, the FLS-C measuring device has an accuracy of ±1 mm 2σ (FLS-C(H) 10) respectively ±3 mm 2σ (FLS-C(H) 30). Measuring rate depends on environmental conditions such as target surface, distance, background light (e.g. sun light), etc. Good environmental conditions increase measuring rate (e.g. white target surface or orange reflective target plate and dark environment).

For a detailed description of the different measuring characteristics see 3.4 Measuring characteristics on page 12.

The configuration command sNuc is applied to the special user commands and to the standard commands.

Every error will be preserved. For an error reset, the measurement must be restarted according to the configured operation mode. (See 3.4.3 Error behavior on page 14)

1: Moving target characteristic without error freezing

Distance jumps or unfavorable signal conditions may cause a temporary or permanent error.

Temporary error

As soon as the FLS is able to determine a new distance value, the error will disappear and the output will show the new distance value. The shortest possible time to display an error is 4..5ms.

Permanent error

The FLS is not able to determine a distance anymore. The error will be shown with an output rate of up to 250Hz. For an error reset, the measurement must be restarted according to the configured operation mode. (See 3.4.3 Error behavior on page 14)

9.3.3 Set auto start configuration (sNA)

This command activates the stand-alone mode with auto start of the DLS-C(H)/FLS-C(H). It triggers continuous measurements of the distance. The analog, digital and SSI outputs are updated according to the measured distance values. The sampling time defines the measurement rate. If the sampling time is set to zero, the measurements are executed as fast as possible (depending on target conditions). The stand-alone mode with auto start is active until the STOP/CLEAR command (sNc) is received by the device.

The operating mode is stored in the DLS-C(H)/FLS-C(H) and activated immediately. This mode is also activated after next power ON.

Internally, “tracking with buffering” is started (command sNf). Therefore, the latest measurement can also be read out from the module with the command sNq.
