This chapter describes the functions of the light curtain for adaptation to different applications and oper­ating conditions.

4.1 Beam modes

4.1.1 Parallel

In “parallel”-beam mode (parallel-beam scanning), the light beam of eac the directly opposing receiver LED.
Functions

Figure 4.1: Beam path in “parallel”

4.1.2 Diagonal

In “diagonal” beam mode, the light beam of each transmitter diode is received in succession both by the directly opposing receiver diode as well as by the next receiver diode in the counting direction (i-1) (parallel and diagonal beam path). This increases the resolution in the middle between the transmitter and receiver.

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.
The “diagonal” beam mode (diagonal-beam scanning) can be activated via the respective field- bus interface (see chapter 9 et seq.) or via the
Sensor Studio
configuration software (see
chapter 12).
NOTICE
Minimum distance for diagonal-beam scanning!
For diagonal-beam scanning, the minimum distance that must be maintained between transmitter and
receiver changes, whereby the values vary depending on beam spacing (see chapter 16).
NOTICE
Teach after changing the beam mode!
Changing the beam mode changes the number of beams used for the evaluation. Perform a teach
after changing the beam mode (see chapter 8.2).

4.1.3 Crossed-beam

The “crossed-beam” mode (crossed-beam scanning) is available for increasing the resolution for an area of the measurement field. In “crossed-beam” mode, the light beam of each transmitter LED is detected in succession both by the directly opposing receiver LED as well as by the two adjacent receiver LEDs (i+1, i-1).

NOTICE
Minimum distance for crossed-beam scanning!
For crossed-beam scanning, the minimum distance that must be maintained between transmitter and
receiver changes, whereby the values vary depending on beam spacing (see chapter 16).
Example: 288 beams in parallel-beam scanning become 862 logical beams in crossed-beam scanning. With a beam spacing of 5 mm, this spacing is reduced to 2.5 mm in the center area.
The “crossed-beam” mode (crossed-beam scanning) can be activated via the respective fieldbus interface (see chapter 9 et seq.) or via the
Sensor Studio
configuration software (see
chapter 12).

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.
The 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
Leuze electronic CML 720i Ex 25
For width detection, counting can begin with 1 at either end at the head part of the sensor as shown below:

4.3 Beam-stream

The single-beam evaluation (beam-stream) returns the status of each individual beam (see figure 4.4). Uninterrupted beams (free beams) are represented as logical 1 in the output bit in this case.
The data is available via the respective fieldbus interface (see chapter 9 et seq.) or via the

4.4 Evaluation functions

Leuze electronic CML 720i Ex 26
The states of the individual optical beams (free/interrupted) can be evaluated in the CML 700i and the result read out via various evaluation functions.
The most important evaluation functions are shown in the following figure:

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

The setting of the hold times is performed via the respective fieldbus interface (see chapter 9 et seq.) or via the
Sensor Studio
The minima and maxima of the following evaluation functions can be temporarily stored for an adjustable period of time via this function:
• First interrupted beam (FIB)
• First not interrupted beam (FNIB)
• Last interrupted beam (LIB)
• Last not interrupted beam (LNIB)
• Total of interrupted beams (TIB)
• Total of not interrupted beams (TNIB)
• Single-beam evaluation (beam-stream): A beam that has been interrupted once is kept at logical 0 in the output bit until the hold time has expired.
Temporary storage 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.
configuration software (see chapter 12).

4.6 Blanking

If light curtains are installed such that existing frames / cross bars etc. continuously interrupt some beams, these beams must be suppressed.
During blanking, beams that are not to be included in the evaluation are suppressed. The numbering of the beams is not affected, i.e., the suppression of beams does not change the beam numbers.

Up to four adjacent beam areas can be suppressed.
The beams can be activated or suppressed via the respective fieldbus interface (see chapter 9 et seq.), via the
Sensor Studio
configuration software (see chapter 12) and partially via the oper-
ational controls on the receiver.
The 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.

4.7 Power-Up Teach

After applying operating voltage, the “Power-Up Teach” function performs a teach event when the device is ready for operation.
• If the Power-Up teach is successful, the new teach values are adopted if they are different from the previously stored teach values.
• If the Power-Up teach is not successful (e.g. object in the light path), the previously saved teach val­ues are used.
The “Power-Up Teach” event can only be activated via the receiver control panel.

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.
Smoothing can be used, e.g., to suppress interference caused by spot soiling of the lens cover. Smoothing “1” means that every interrupted beam is evaluated.

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 11.5.

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. This is ensured by activating (trig­gering) with a time offset.
The following light curtain arrangements are possible in a cascade arrangement:
• Multiple light curtains above one another, e.g., for height monitoring

4.9.2 Internal triggering

With internal trigger activation, a CML 700i configured as "master light curtain" generates the trigger pulse. This trigger pulse is continuous; this means that no further activation is required from a primary control.
Trigger output The trigger output of the master light curtain makes available the trigger signal necessary for “cascading

4.10.1 Defining beam area

To read out the beam states block­mapped to up to 32 areas independent of the maximum beam number. The individual beam information of grouped beams is linked to a logical bit, i.e., each area is represented as 1 bit.
The number of beams in an area can be freely defined. However, the beams must be adjacent to one another. The start beam and the end beam are to be defined as well as the conditions for switching of the area.

4.10.3 Mapping beam area to switching output

If grouping individual beams or if creating a block, the beam sta can be signaled at a switching output.
The following options are possible here:
• To use a specific, single beam for the evaluation, e.g., as trigger signal for a primary control.
• To 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.
• To 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.
The switching conditions for the areas can be either AND or OR linked:
Logic func­tion
Group bit (area status) [logic 1/0]
AND 1 If all beams mapped to the area are interrupted
0 If at least one beam is not interrupted in the selected area
OR 1 If at least one beam is interrupted in the selected area

te of any number of adjacent beams (area)
0 If none of the beams mapped to the area are interrupted
Areas may be sequential or overlapping. A maximum of 32 areas are available.
The switching behavior or the conditions for switching a beam area on and off can be defined via the respective fieldbus interface (see chapter 9 et seq.) or via the
Sensor Studio
configuration
software (see chapter 12).
For an example configuration, see chapter 11.2.

Take into account the (increased) number of beams if the “diagonal”- or “crossed-beam” mode is acti-
vated (see chapter 4.1.2 or see chapter 4.1.3).

4.10.4 Teach height area

With the “Teach 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. Therefore, the object cannot be located in the center of the measurement field length; the first or last beam must be interrupted.

• The switching behavior or the conditions for switching the height area on or off via the “Teach height area” function is permanently defined as OR.
• Every IO pin can be assigned to a height area via the receiver control panel. Example: Digital IOs > IO Pin 2 > Teach height > Execute
On the receiver control panel, the “Teach height area” function is activated via the Teach height menu item. Example: Digital IOs > IO Pin 2 > Teach height > Execute
If the “Teach height area” function is activated via the receiver control panel, the IO pins are auto- matically assigned to the height areas.

4.12 Interference suppression (filter depth)

To suppress any faulty measurement values that may occur due to interference (ambient light, electromag­netic fields, …), the filter depth of the light curtain can be increased.
“Filter depth” means that an interrupted/free beam is not included in the further data evaluation until the same beam status is recorded for the set number of measurement cycles.
Filter depth “1” = the beam states of each measurement cycle are output. Filter depth “3” = only those beam states that were stable over three measurement cycles are output.
Filter depth can be configured via the respective fieldbus interface (see chapter 9 et seq.) or via

6.1 Mounting the light curtain

NOTICE
No reflective surfaces, no mutual interference!
Avoid reflective surfaces near the light curtains.
Objects may otherwise not be precisely detected due to halation.
Ensure sufficient distance, suitable positioning or partitioning.
Optical sensors (e.g., other light curtains, photoelectric sensors, etc.) must not interfere with one another.
Avoid interference from outside light (e.g., from flash lamps, direct sunlight) on the receiver.
Mount the transmitter and receiver as follows:
Select the fastening type for transmitter and receiver.
- Fastening via the T-groove on one side of the standard profile (see chapter 6.3).
- Fastening via the rotating bracket on the ends of the profile (see chapter 6.4).
- Fastening via the swiveling mounting brackets or parallel brackets (see chapter 6.5).
Have a suitable tool at hand and mount the light curtain in accordance with the notices regarding the
mounting locations.
Mount the transmitter and receiver at the same height or with the same housing reference edge, free of
tension and with the base in full contact with the mounting surface.
Mounting and installation
NOTICE
Must be observed!
For horizontally mounted measuring light curtains with lengths of more than 2,000 mm, use an addi-
tional mounting bracket in the middle of the light curtain.
The optical surfaces of transmitter and receiver must be parallel to and opposite one another.
The transmitter and receiver connections must point in the same direction.
Secure transmitter and receiver against turning or sliding.

Mounting and installation
To achieve the maximum operating range limit, transmitter and receiver must be aligned with one another as accurately as possible.
After mounting, you can electrically connect (see chapter 7) and start up (see chapter 8) the light curtain.

6.2 Definition of directions of movement

The following terms for alignment movements of the light curtain around one of its individual beams are used:
a Sliding: movement along the longitudinal axis b Turning: movement around the longitudinal axis c Tilting: lateral turning movement diagonal to the lens cover d Pitching: lateral turning movement in the direction of the lens cover
Figure 6.2: Directions of movement during alignment of the light curtain

6.3 Fastening via sliding blocks

By default, transmitter and receiver are delivered with two sliding blocks (three sliding blocks for measure­ment field lengths of more than 2,000 mm) each in the side groove (see chapter 17).
Fasten transmitter and receiver to the machine or system via the lateral T-groove with M6 screws.
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 BT-2R1 swivel mount (see table 17.8), sold separately, the light curtain can be aligned as follows:
• Sliding through the vertical threaded holes in the wall plate of the swivel mount
• Turning by 360° around the longitudinal axis by fixing on the screw-on cone
• Tilting around main axis
• Pitching through horizontal threaded holes in the wall mounting
The wall mounting through threaded holes makes it possible to lift the mounting bracket after the screws have been loosened over the connection cap. Therefore, the mounting brackets do not need to be removed from the wall when exchanging the device. Loosening the screws is sufficient.
Figure 6.4: Mounting via swivel mount

Mounting and installation
One-sided mounting on the machine table The sensor can be mounted directly on the machine table via an M5 screw on the blind hole in the end
cap. On the other end, a BT-2R1 swivel mount can be used, for example, so that turning movements for alignment are possible despite the fact that the sensor is mounted on one side.
NOTICE
Avoid reflection bypasses at the machine table!
Make sure that reflections on the machine table and in the vicinity are prevented reliably.

6.5 Fastening via swiveling mounting brackets

When mounting with the BT-2SSD/BT-4SSD or BT-2SSD-270 swiveling mounting brackets (see table 17.8), sold separately, the light curtain can be aligned as follows:
• Sliding in the direction of slot
• Turning +/- 8° around the longitudinal axis
The BT-SSD (see figure 16.5) swiveling mounting brackets are also equipped with a vibration damper.

WARNING
Safe use of the sensor in potentially explosive areas!
Observe the information on the safe use of sensors in potentially explosive areas; see chapter 2.5.

7.1 Shielding and line lengths

The 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

NOTICE
General shielding information!
Avoid interference emissions when using power components (frequency inverters, …).
The 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
NOTICE
Separate power and control cables!
Devices with connector must be equipped with a safeguard or a mechanical interlocking guard; see
table 17.9.
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.
NOTICE
Lay cables close to grounded metal surfaces!
Lay the cables on grounded metal surfaces
This measure reduces interference coupling in the cables.
NOTICE
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.
Leuze electronic CML 720i Ex 48
Page 49
Electrical connection
NOTICE
Star-shaped cable connections!
Ensure that the devices are connected in a star-shaped arrangement.
You thereby avoid mutual influences from various loads.
This prevents cable loops.
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).
The 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, …).
Use 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.
The 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.
Figure 7.1: Connecting the ground potential to the light curtain
Example for shielding both ends of the connection cables from the switch cabinet to the light curtain
Ground the transmitter housing and receiver housing of the light curtain (see chapter "Grounding the
light curtain housings").
Clamp the shield in the switch cabinet flat to FE (see figure 7.2).
Use special shielding terminals (e.g., Wago, Weidmüller, …).

The following optional basic functions are available for operation and configuration via the receiver control panel:
• Define digital inputs/outputs
• Defining the filter depth
• Defining the display properties
• Changing the language
• Product information
• Resetting to factory settings

8.1 Aligning transmitter and receiver

NOTICE
Alignment during commissioning!
The alignment performed during commissioning should only be performed by qualified personnel.
Observe the data sheets and mounting instructions of the individual components.
Starting up the device - Basic configuration
Prerequisites:
• The light curtain has been mounted (see chapter 6) and connected (see chapter 7) correctly.
Switch on the light curtain.
NOTICE
Alignment mode!
When switched on for the first time ex works, the light curtain automatically starts in process mode.
You can switch from process mode to alignment mode via the control panel.
Check whether the green LEDs on the receiver control panel and transmitter illuminate continuously.
The display shows the alignment state of the first beam (FB) and last beam (LB) via two bar graph indica­tors.

The next configuration step is teaching the environmental conditions (teach).

8.2 Teaching the environmental conditions

During teaching, the system checks whether the signals of all beams are within a certain corridor. This means that a teach event generally regulates all beams to the preset function reserve (or sensitivity)
for the current operating range. This ensures that all beams exhibit an identical switching behavior.
NOTICE
Conditions for performing a teach!
When teaching without preconfigured blanking areas, the light path must always be completely free.
A teaching error will otherwise occur.
In this case, remove the obstacles and repeat the teach.
If the light path is partially interrupted by structural elements, the permanently interrupted beams can
be suppressed by means of blanking ( this case.
To automatically suppress the affected beams during teaching, configure the number of blanking
areas via the configuration software

function). Interrupted beams are “deactivated” in
(see chapter 12).
Starting up the device - Basic configuration
The configuration can be performed via the respective fieldbus interface (see chapter 9 et seq.) or via the
Sensor Studio
configuration software (see chapter 12).
You can choose whether the teach values are to be stored permanently or only temporarily (while the operating voltage is applied). The configuration ex works is for permanent (non-volatile) stor- age.
A teach event can be performed both directly from process mode as well as from alignment mode.
NOTICE
Execute teach after changing the beam mode!
Always perform a teach after changing the beam mode (parallel-/diagonal-/crossed-beam scanning)
as well.
Prerequisites:
• The light curtain must be correctly aligned (see chapter 8.1).
• The bar graph indicator must show a minimum level.
You can use one of the following teach types:
Teach via receiver control panel (see chapter 8.2.1).
Teach via teach input (see chapter 8.2.2).
Teach via fieldbus interface (IO-Link, see chapter 9; CANopen, see chapter 10).
Teach via
Sensor Studio
configuration software (see chapter 12).

8.2.1 Teach 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.
The structure of the configuration in the receiver control panel menu is as follows:

If the teach was started while in process mode, the display returns to the process mode display after a successful teach (see chapter 8.1).
If the teach was started from alignment mode, the display returns to the bar graph indicator following a successful teach and shows the received signal level of the first beam (FB) and the last beam (LB) (see chapter 8.1).
If teach is successful, both bars display the maximum value.
Figure 8.4: Display after successful teach
If no bars are visible in the bar graph indicator for the first beam (FB) and the last beam (LB), an error has occurred. It is possible, e.g., that the reception signal is too low. You can correct errors according to the error list (see chapter 13).

8.3 Check alignment

Prerequisites:
• The light curtain must first be correctly aligned and a teach must be performed.
Check whether the green LEDs on the receiver control panel and transmitter illuminate continuously.
Use the bar graph indicator to check whether the light curtain is optimally aligned, i.e., whether the max-
imum is reached for both the first beam (FB) and the last beam (LB) in the bar graph indicator.
Use the bar graph indicator to check the optimum alignment of the light curtain if you have corrected an
error that occurred.

• Perform extended configurations on the receiver control panel if necessary (see chapter 8.5)
• Start up CML 700i light curtains with IO-Link interface (see chapter 9)
• Start up CML 700i light curtains with CANopen interface (see chapter 10)

8.4 Setting the function reserve

The function reserve can be set to three levels:
• High function reserve (low sensitivity)
• Medium function reserve
• Low function reserve (high sensitivity)
The function reserve can be set via the receiver control panel and the ware (see chapter 12).
The function reserve can be set via the receiver control panel, via the respective fieldbus interface (see chapter 9 et seq.) or via the

Process data settings (group 6)
The process data settings describe the cyclically transmitted process data.
The process data extension permits the serial output of the individual pieces of beam data. Each individual beam can be processed and transferred as a bit independent of measurement field length, resolution and beam mode (beginning with firmware version v2.10).
NOTICE
A maximum of 256 beams can be processed as a bit!
The IO-Link specification only permits 32 bytes as process data; i.e., up to 256 beams can each be
processed and transmitted as a bit.
Through the limitation of the process data length, the beams, depending on the resolution, can only
be processed and transmitted up to a certain measurement field length as a bit.
Leuze electronic CML 720i Ex 71
Page 72
Starting up the device - IO-Link interface
Examples for the limitation of the measurement field length:
• Resolution of 5 mm: Measurement field length up to 1280 mm
• Resolution of 10 mm: Measurement field length up to 2560 mm
• Resolution of 20 mm, 40 mm: No limitation of the measurement field length

10 Starting up the device - CANopen interface

The configuration of a CANopen interface involves the following steps on the receiver control panel and in the control-specific configuration software.
General prerequisites:
• The measuring light curtain has been mounted (see chapter 6) and connected (see chapter 7) cor­rectly.
• The basic configuration has been performed (see chapter 8).

10.1 Defining the CANopen basic configuration on the receiver control panel

The parameters for the CANopen interface are defined with the node ID and bit rate configurations. The structure of these configurations in the receiver control panel menu is as follows:
Level 0 Level 1 Level 2 Description
Main Settings
Commands
Operational setting
IO-Link
CANopen Node ID (enter value)
Bit rate 1000 kbit/s 500 kbit/s 250 kbit/s 125 kbit/s
min = 1 max = 127
Prerequisites:
• The measuring light curtain must be correctly aligned (see chapter 8.1).
• The measuring light curtain must be correctly taught (see chapter 8.2).
The following procedure describes the configurations for CANopen interfaces.
Select Main Settings > CANopen > Node ID > Enter value.
Select Main Settings > CANopen > Bit Rate > Enter value.
The CANopen address (Node ID) and bit rate are configured. Other possible configuration steps are performed via the
Sensor Studio
configuration software (see
chapter 12). Process mode is configured via the control-specific CANopen interface of the CANopen master.

10.2 Defining configurations via the PLC-specific software of the CANopen master

General prerequisites:
• The measuring light curtain has been mounted (see chapter 6) and connected (see chapter 7) cor­rectly.
• The basic configuration has been performed (see chapter 8).
• The CANopen basic configurations have been performed:
• CANopen node ID selected
• CANopen bit rate selected
Specific prerequisites:
• The CANopen-specific EDS file must be installed on the control.
The CANopen device description (EDS file) can be used for direct configuration with connected light curtain.
An EDS file is supplied with the product. It can also be downloaded from the Internet at www.leuze.com.

NOTICE
Configuration dependent on the control-specific software!
The sequence of the configurations is dependent on the control-specific software.
First configure the EDS file while
off-line
.
Once all parameters have been configured, transmit the EDS configurations to the CML 700i.
Information on using the configuration parameters can be found in the general descriptions of the individual functions of the CML 700i (see chapter 4).
Open the interface configuration software.
Configure the following parameters:
- Operating mode (parallel-beam; diagonal-beam; crossed-beam scanning)
- Blanking settings
- Teach settings
Perform a teach. This is possible via the receiver control panel or the control group in the CANopen pro-
cess data (CANopen object 0x2200).
If necessary, configure additional parameter/process data (see chapter 10.3).
Save the configuration via the control group in the CANopen process data (CANopen object 0x2200).
The CANopen-specific configurations have been performed and the CML 700i is ready for process mode.

10.3 Parameter- / process data for CANopen

The configuration parameters or process data for CANopen is defined via the following object descriptions.

The following standard procedure for the TPDO mapping may vary depending on the used con- figuration software.
Standard procedure for the TPDO mapping:
Set the device to the
Preoperational
state.
In the desired TPDO Transmit 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.
This sets the invalid bit, thereby making the TPDO entry invalid.
In the desired TPDO Transmit 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.
Then reset this entry to the number of desired mapping elements, whereby a maximum of 4 elements
per TPDO are possible.
Transmit 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 TPDO Transmit PDO mapping parameter 1 … 28
object to the device.
In the TPDO Transmit PDO communication parameter 1 … 28 object (objects 0x1800 … 0x181B), set

In the same TPDO object, set the COB-ID (sub-index 1) to 0x00000xxx (where the xxx part is node-
dependent) and transmit the complete TPDO object including all sub-indices to the device. This resets the invalid bit, thereby making the TPDO entry valid.
