Example: 288 beams in parallel-beam scanning become 575 logical individual beams in diagonal-beam scanning, which must be taken into account during evaluation functions. With a beam spacing of 5 mm, this spacing is reduced to 2.5 mm in the center area.

configuration software (see

chapter 15).

4.2 Measurement beam sequence

By default, the counting direction of the beams begins at the sensor connection unit. It can, however, be reconfigured so that counting begins with 1 at the sensor head.

≤he simplest application case for the inverted beam sequence is vertical mounting with the connection unit at the top, e.g., for height measurement, where beam 1 is to begin at the bottom:

a Receiver connection unit b Optical part

Another variant with two successive light curtains, where the second is rotated by 180° and counting again begins with 1, is illustrated as follows:

a Receiver connection unit

4.4 Evaluation functions

≤he states of the individual optical beams (free/interrupted) can be evaluated in the CML 700i and the result read out via various evaluation functions.

≤he most important evaluation functions are shown in the following figure:

Functions

1 Number of all interrupted beams (≤IB) 2 Number of all uninterrupted beams(≤NIB) 3 Last interrupted beam (LIB) 4 Last uninterrupted beam (LNIB) 5 First uninterrupted beam (FNIB) 6 First interrupted beam (FIB)

Also included among the evaluation functions are:

• the status of beam areas 1 … 32

• the status of the digital inputs/outputs

For the beam area mappings to an output pin or the status of the digital inputs/outputs, see chapter 4.10.

4.5 Hold function

≤he setting of the hold times is performed via the respective fieldbus interface (see chapter 10 et seq.) or via the

≤he minima and maxima of the following evaluation functions can be temporarily stored for an adjustable period of time via this function:

• First uninterrupted beam (FNIB)

• Last interrupted beam (LIB)

• Number of all interrupted beams (≤IB)

• Number of all uninterrupted beams (≤NIB)

≤his simplifies the reading out of the measurement results if the used control cannot transmit the data at the same speed that the light curtain makes the data available.

4.6 Blanking

If light curtains are installed such that existing frames / cross bars etc. continuously interrupt some beams, these beams must be suppressed.

Leuze electronic CML 730i 28

Functions

During blanking, beams that are not to be included in the evaluation are suppressed. ≤he numbering of the beams is not affected, i.e., the suppression of beams does not change the beam numbers.

≥p to four adjacent beam areas can be suppressed.

≤he beams can be activated or suppressed via the respective fieldbus interface (see chapter 10 et seq.), via the

Sensor Studio

configuration software (see chapter 15) and partially via the op-

erational controls on the receiver.

≤he behavior of each blanking area can be adapted to the requirements of the application:

Logical value of a blanking area Meaning in the application

No beams are blanked All beams of the device are included in the evaluation.

Logical value 0 for blanked beams All beams of the blanking area are taken into account

as interrupted beams (logical value 0) in the evaluation.

Logical value 1 for blanked beams All beams of the blanking area are taken into account

as free beams (logical value 1) in the evaluation.

Logical value is the same as the adjacent beam with lower beam number

Logical value is the same as the adjacent beam with higher beam number

All beams of the blanking area behave in the evaluation like the previous beam.

All beams of the blanking area behave in the evaluation like the subsequent beam.

For an example configuration, see chapter 14.4.

4.8 Smoothing

With the smoothing function, interrupted beams are then only taken into account in the evaluation if the set minimum number of adjacent beams is reached at the same time.

Leuze electronic CML 730i 30

Smoothing can be used, e.g., to suppress interference caused by spot soiling of the lens cover.

Configuration values for smoothing!

 Values from 1 to 255 can be entered for smoothing.

Inverted smoothing Inverted smoothing can suppress interference near the edges of objects, since uninterrupted beams are

not evaluated until the set number is reached. With inverted smoothing it is possible to detect, e.g., only successive openings of a certain minimum size

within a web. For an example configuration, see chapter 14.5.

4.9 Cascading/triggering

If the measurement field length of a light curtain is not sufficient for detecting a desired measurement path, multiple light curtains can be connected in series or cascaded. When doing so, it must be ensured that the light curtains do not mutually influence or interfere with one another. ≤his is ensured by activating (triggering) with a time offset.

≤he following light curtain arrangements are possible in a cascade arrangement:

• Multiple light curtains above one another, e.g., for height monitoring

manner by means of a pulse at the trigger input. In this way, mutual interference can be prevented in applications with multiple light curtains. ≤his trigger signal generated in the control must be wired at all cascaded light curtains.

≤rigger output ≤he trigger output of the master light curtain makes available the trigger signal necessary for cascading

4.10 Block evaluation of beam areas

With this function, the quantity of data to be transmitted can be reduced by restricting the imaging accuracy. ≤he minimum resolution of the light curtain is still retained.

4.10.1 Defining beam area

≤o read out the beam states block-wise with a 16-bit or 32-bit telegram, the individual beams can be mapped to up to 32 areas independent of the maximum beam number. ≤he individual beam information of grouped beams is linked to a logical bit, i.e., each area is represented as 1 bit.

≤he number of beams in an area can be freely defined. However, the beams must be adjacent to one another. ≤he start beam and the end beam are to be defined as well as the conditions for switching of the area.

NO≤ICE

 ≤he hold function (see chapter 4.5) also applies for the block evaluation of beam areas.

4.10.2 Autosplitting

≤he beams of the device are automatically divided into the selected number of areas of the same size. ≤he states of the areas generated in this way can be read out in the process data by means of the Area Out HiWord and Area Out - LoWord parameters.

Procedure:

• Select logic combination of the beams within the areas (logical AND / logical OR)

• Define the number of desired areas (e.g., 16 or 32)

≤he autosplitting configuration can be defined via the respective fieldbus interface (see chapter 10 et seq.) or via the

Sensor Studio

configuration software (see chapter 15).

4.10.3 Mapping beam area to switching output

If grouping individual beams or if creating a block, the beam state of any number of adjacent beams (area) can be signaled at a switching output.

≤he following options are possible here:

• ≤o use a specific, single beam for the evaluation, e.g., as trigger signal for a primary control.

• ≤o group the complete measurement field into one switching area and thereby signal at the switching output whether an object (at any position) is located in the measurement field.

• ≤o configure up to 32 switching areas for a reference check or height monitoring; in many cases, this can make beam-data processing in the primary programmable logic control (PLC) unnecessary.

≤he switching conditions for the areas can be either AND or OR linked:

With the ≤each height area function, it is possible to teach in up to four height areas, e.g. for height monitoring or sorting packets. In many cases, this saves time for programming.

• A maximum of four height areas are available.

• A height area is automatically defined using an object. When teaching a height area, all free beams above or below the object are combined into one height area. ≤herefore, the object cannot be located in the center of the measurement field length; the first or last beam must be interrupted.

Sliding in the direction of the groove is possible, but turning, tilting and pitching is not.

Mounting and installation

Figure 6.3: Mounting via sliding blocks

6.4 Fastening via swivel mount

When mounting with the B≤-2R1 swivel mount (see table 20.21), sold separately, the light curtain can be aligned as follows:

• Sliding through the vertical threaded holes in the wall plate of the swivel mount

• ≤urning by 360° around the longitudinal axis by fixing on the screw-on cone

• ≤ilting around main axis

• Pitching through horizontal threaded holes in the wall mounting

≤he wall mounting through threaded holes makes it possible to lift the mounting bracket after the screws have been loosened over the connection cap. ≤herefore, the mounting brackets do not need to be removed from the wall when exchanging the device. Loosening the screws is sufficient.

7.1 Shielding and line lengths

≤he light curtains are equipped with modern electronics developed for industrial applications. In industrial environments, a number of sources of interference may affect the light curtains.

In the following, information is provided on the EMC-compliant wiring of the light curtains and the other components in the switch cabinet.

7.1.1 Shielding

NO≤ICE

General shielding information!

 Avoid interference emissions when using power components (frequency inverters, …).

≤he necessary specifications under which the power component satisfies its CE Declaration of Conformity can be found in the technical descriptions of the power components.

In practice, the following measures have proven effective:

Properly ground the total system.

Screw mains filter, frequency inverter, etc., flat to a galvanized mounting plate (thickness 3 mm) in the switch cabinet.

Keep cable between mains filter and inverter as short as possible and twist cables.

Shield both ends of the motor cable.

 Carefully ground all parts of the machine and of the switch cabinet using copper strips, ground rails or

grounding cables with large cross section.

 Keep the length of the shieldless end of the cable as short as possible.

 Guide the shielding untwisted to a terminal (no RF braid).

Electrical connection

NO≤ICE

Separate power and control cables!

 Lay the cables for the power components (mains filter, frequency inverter, …) as far from the light cur-

tain cables as possible (distance > 30 cm).

 Avoid laying power and light curtain cables parallel to one another.

 Cable crossings should be laid as perpendicular as possible.

NO≤ICE

Lay cables close to grounded metal surfaces!

 Lay the cables on grounded metal surfaces

≤his measure reduces interference coupling in the cables.

NO≤ICE

Avoid leakage currents in the cable shielding!

 Carefully ground all parts of the machine.

Leakage currents arise from incorrectly implemented equipotential bonding.

You can measure leakage currents with a clip-on ammeter.

NO≤ICE

Star-shaped cable connections!

 Ensure that the devices are connected in a star-shaped arrangement.

You thereby avoid mutual influences from various loads.

≤his prevents cable loops.

Electrical connection

Grounding the light curtain housings

 Connect the transmitter housing

and receiver housing of the light curtain to the protective conductor on

the FE machine star point via the PE screw on the grounding slot nut (see figure 7.1).

≤he cable should have an impedance as low as possible for high-frequency signals, i.e., be as short as possible and have a large cross-sectional area (grounding strip, …).

 ≥se a lock washer and check the penetration of the anodized layer.

 Check the small Allen screw to ensure a secure connection between the grounding slot nut and housing.

≤he Allen screw is correctly tightened upon delivery from the factory.

If you have changed the position of the grounding slot nut or the PE screw, tighten the small Allen screw.

Execute teach after changing the beam mode!

 Always perform a teach after changing the beam mode (parallel-/diagonal-/crossed-beam scanning)

as well.

Prerequisites:

• ≤he light curtain must be correctly aligned (see chapter 8.1).

• ≤he bar graph indicator must show a minimum level.

 You can use one of the following teach types:

≤each via receiver control panel (see chapter 8.2.1).

≤each via teach input (see chapter 8.2.2).

≤each via fieldbus interface (IO-Link, see chapter 10; CANopen, see chapter 11; Profibus, see chapter 12; RS 485 Modbus, see chapter 13).

≤each via

configuration software (see chapter 15).

8.2.1 ≤each via receiver control panel

If blanking areas are configured via the configuration software interface, a teach event is performed that takes these blanking areas into account (blanking teach or auto blanking, see chapter 4.6).

During a blanking teach or auto blanking, an additional distance is always added to the beams detected as interrupted. Safer operation is thereby achieved, e.g., in the case of vibrating guides, etc., in the blanked area.

Optimization of the blanked beams is to be performed via a software interface configuration.

A maximum of four adjacent areas of suppressed beams (blanking areas) can be configured.

9.3 Behavior of the analog output

≤he output logic of the CML 700i returns the output signals to the programmable logic control (PLC). On interface X1, two pins can be assigned as output for the analog control of the PLC process interface.

≤he selected beam area (start beam/end beam) is mapped to the analog output of the CML 700i. ≤he conversion is by means of a 12-bit D/A converter, whereby the 12-bit value (4096) is divided by the selected number of beams. ≤he resulting values, mapped to the respective, configured analog values, yield the characteristic curve. If there are only a few beams, this results in an erratic characteristic curve.

≤he beams used for the measurement can be freely defined via the receiver control panel. It is also possible to specify that only a part of the beam area be used for the measurement.

≤he following standard procedure for the ≤PDO mapping may vary depending on the used con- figuration software.

Standard procedure for the ≤PDO mapping:

 Set the device to the

Preoperational

state.

 In the desired ≤PDO ≤ransmit PDO communication parameter 1 … 28 (objects 0x1800 … 0x181B), set

the COB-ID (sub-index 1) to 0x80000xxx (where the xxx part is node-dependent) and transmit this COB-ID to the device.

≤his sets the invalid bit, thereby making the ≤PDO entry invalid.

 In the desired ≤PDO ≤ransmit PDO mapping parameter 1 … 28 (objects 0x1A00 … 0x1A1B), set the

entry for the number of the following elements (sub-index 0,

numOfEntries

) to 0 and transmit this to the

device.

An existing mapping is thereby deleted.

 ≤hen reset this entry to the number of desired mapping elements, whereby a maximum of 4 elements

per ≤PDO are possible.

≤ransmit this entry back to the device.

 Set the mapping entries to the desired values. Each of the mapping sub-indices contains a 32-bit value

that is structured as follows: SDO object number, sub-index and length. Normally (depending on the used master), the respective settings can be selected from a list.

 After completing the mapping, transmit the complete ≤PDO ≤ransmit PDO mapping parameter 1 … 28

object to the device.

 In the ≤PDO ≤ransmit PDO communication parameter 1 … 28 object (objects 0x1800 … 0x181B), set

the transmission type (sub-index 2

Event timer

≤ransmission type

) and, if applicable, the event timer (sub-index 5,

 In the same ≤PDO object, set the COB-ID (sub-index 1) to 0x00000xxx (where the xxx part is node-

dependent) and transmit the complete ≤PDO object including all sub-indices to the device. ≤his resets the invalid bit, thereby making the ≤PDO entry valid.

 Set the device to the
