2. Product
2.1. Main features
IO-Link RS Components 4-
wire DC photoelectric Background Suppression sensors, built to the
highest quality standards, are available in Plastic (PBT) IP67 approved housing material.
They can operate in standard I/O mode (SIO), which is the default operation mode. When
connected toan SCTL55 or an IO-Link master, they automatically switch to IO-
Link mode and can
be operated and easily configured remotely.
ThankstotheirIO-Linkinterface,thesedevicesaremuchmoreintelligentandfeaturemanyadditional
configuration options, such
as the settable sensing distance and hysteresis, also timer functions of
the output. Advanced
functionalities such as the Logic function block and the possibility to
convert one output into an external input makes the sensor highly flexible.
Application f
unctions such as; Pattern recognition, Speed and Length monitoring, Divider function
and Object and Gap detection are de-central functions dedicated to solve specific sensing tasks.

2.3. Operating modes
IO-Link photoelectric sensors are provided with two switching outputs (SO) and can operate in
two differentmodes: SIO mode (standard I/O mode) or IO-Link mode (pin 4).
2.3.1. SIO mode
When the sensor operates in SIO mode (default), a SCTL55 or an O-
Link master is not required. The
device
works as a standard photoelectric sensor, and it can be operated via a fieldbus device or
a controller (e.g. a PLC) when connected to its PNP, NPN or push-pull digital inputs (standard I/O
port). One of the greatest benefits
of these photoelectric sensors is the possibility to configure them
via a SCTL55 or an O-Link master and then, once disconnected from the master, they will keep
the last parameter and configuration settings. In this way it is possible, for example, to configure
the outputs of the sensor individually as a PNP, NPN or push-pull, or
to add timer functions such as
T-on and T-off delays or logic functions and thereby satisfy several application requirements
with
the same sensor
2.3.2. IO-Link mode
IO-Link is a standardized IO technology that is recognized worldwide as an international standard (IEC
61131-9).
It is today considered to be the “USB interface” for sensors and actuators in the industrial
automation environment. When the sensor is connected to one IO-Link port, the SCTL55 or IO-
Link
master sends a wakeup request (wake up pulse) to the sensor, which automatically switches to IO-
Link
mode: point-to-point bidirectional communication then starts automatically between the master and
the sensor.
IO Link communication requires only standard 3 wire unshielded cable with a maximum length of 20
C/Q
2 4
1
3
L
L+
IO-Link communication takes place with a 24 V pulse modulation, standard UART protocol via the
switching andcommunication cable (combined switching status and data channel C/Q) PIN 4 or
black wire.
For instance, an M8 4-pin male connector has:
•Positive power supply: pin 1, brown
•Negative power supply: pin 3, blue
•Digital output 1: pin 4, black
•Digital output 2: pin 2, white
The transmission rate of 2377276 and 2377277 sensors is 38.4 kBaud (COM2).
Once connected to the IO-
Link port, the master has remote access to all the parameters of the
sensor and to advanced functionalities, allowing the settings and configuration to be changed
during operation, and enabling diagnostic functions, such as tempera
ture warnings, temperature
alarms and process data.
Thanks to IO-
Link it is possible to see the manufacturer information and part number (Service Data)
of the device connected starting from V1 1 Thanks to the data storage feature it is possible to

Access to internal parameters allows the user to see how the sensor is performing, for example by
reading theinternal temperature.
EventDataallowstheusertogetdiagnosticinformationsuchasanerror,analarm,awarningora
communicationproblem.
There are two different communication types between the sensor and the master and they are
independent ofeach other:
•Cyclical for process data and value status – this data is exchanged cyclically.
•Acyclical for parameter configuration, identification data, diagnostic information
and events(e.g. error messages or warnings) – this data can be exchanged on
request
2.3.3. Process data
By default the process data shows the following parameters as active: 16 bit Analogue value,
SwitchingOutput1 (SO1) and Switching Output 2 (SO2).
The following parameters are set as Inactive: SSC1, SSC2, TA, SC, DA1, DA2, AFO1.
However by changing the Process Data Configuration parameter, the user can decide to also
enable the statusof the inactive parameters. This way several states can be observed in the sensor
at the same time.

2.4. Output Parameters
Seven sensing functions and 4 application functions can be selected. These values can be
independently adjusted
and used as source for the Switching Output 1 or 2; in addition to those, an
external input can be selected for
SO2. After selecting one of these sources, it is possible to
configure the output of the sensor with a SCTL55 or an IO-Link master, following the seven steps
shown in the Switching Output setup below.
Once the sensor has been disconnected from the master, it will switch to the SIO mode and keep
the last configuration setting

2.4.1. Sensor front
The Background Suppression sensor emits light towards a target and measure the position of the
light reflected
from the target. If the measured position value is equal to or less than a predefined
position for the target, the sensor changes the output state. The measured sensing distance
is
almost independent of the target colour
2.4.1.1. SSC (Switching Signal Channel)
For presence (or absence) detection of an object in front of the face of the sensor, the
following settings are available: SSC1 or SSC2. Setpoints can be set from 20 ... 225 mm for
PD30CTB.20..., 20 ... 275 mm forPD30CTBS25... and 20 ... 375 mm for the PD30CTBR35... sensor *.
* It is not recommended to use settings higher than maximum 200, 250 and 350 mm depending on
the sensortype however under optimal conditions (ambient light environment and EMC noise etc.)
the distance can be setat higher value.
2.4.1.2. Switchpoint mode:
Each SSC channel can be set operate in 4 modes or be disabled. The Switchpoint mode
setting can be
used to create more advanced output behaviour. The following switchpoint
modes can be selected for the switching behaviour of SSC1 and SSC2
Disabled
SSC1 or SSC2 can be disabled individually.
Single point mode
The switching information changes, when the distance passes the threshold defined in setpoint
SP1, with rising or falling distances, taking into consideration the hysteresis settings stored in the
sensor.

information also changes
when the distance measured passes the threshold defined in setpoint

increasing distance measured. Hysteresis settings stored in the
sensor are not applied in this case. The
hysteresis results from the difference between SP1 and

2.4.1.3.
Hysteresis Settings
The hysteresis can be set automatically or manually for SSC1 and manually only for SSC2. The
hysteresis isset in mm for SP1 and SP2.
Note: When trimmer is selected, the default hysteresis is Automatic.
Automatic hysteresis:
Automatic hysteresis will guarantee stable operation for most applications.
Hysteresis is calculated with reference to SP1/SP2 and the actual values can be read via
parameter “SSC1Auto hysteresis”, typically 14 mm for PD30CTB.20.., 17 mm for PD30CTBS25...
and 24 mm for PD30CTBR35... for SP1 and SP2.
Manual hysteresis:

PD30CTB.20...,2 ... 275 mm for PD30CTBS25 and 2 ... 375 mm for PD30CTBR...
For application that require a hysteresis other than the automatic, the hysteresis can be
configured manually.This feature makes the sensor more versatile.
Note: Special attention to the application must be considered when choosing a hysteresis
lower than theautomatic hysteresis.
2.4.1.4. Dust alarm 1 and Dust alarm 2
Minimum Excess Gain is used for dust alarm levels and is set as a common value for
both SSC1 and SSC2. The dust alarm will be active after a preset time, if the measured
Excess Gain value isbelow the Minimum Excess gain.
See 2.5.10 Excess Gain.
2.4.1.5. Temperature alarm (TA)
The sensor monitors constantly the internal temperature. Using the temperature alarm setting it is
possible toget an alarm from the sensor if temperature thresholds are exceeded. See §2.5.5.
Two independent temperature alarm settings can be set. One for the maximum temperature
alarm and onefor the minimum temperature alarm.
It is possible to read the temperature of the sensor via the acyclic IO-Link parameter data.
NOTE!
The temperature measured by the sensor will always be higher than the ambient temperature,
due to internalheating.
The difference between ambient temperature and internal temperature is influenced by how
the sensor isinstalled in the application.
2.4.1.6. External input
The output 2 (SO2) can be configured as an external input allowing external signals to be
fed into thesensor, e.g. from a second sensor or from a PLC or directly from machine output.
2
2.4.2. Input selector
This function block allows the user to select any of the signals from the “sensor front” to the
Channel A or B. Channels A and B: can select from SSC1, SSC2, Dust alarm 1, Dust alarm 2, Water
drop alarm 1, Water dropalarm 2, Temperature alarm and External input.
3
2.4.3. Logic function block
In the logic function block a logic function can be added directly to the selected signals from the
input selectorwithout using a PLC – making decentralised decisions possible.
The logic functions available are: AND, OR, XOR, SR-FF.

The recommended function is found in the parameters under 64 (0x40) sub index 8 (0x08) for SO1
and 65 (0x41) sub index 8 (0x08) for SO2. It has no negative influence on the Logic functions or
the
timer functions ofthe sensor as it is added after those functions.
CAUTION!
The Switching logic function found under 61 (0x3D) sub index 1 (0x01) for SSC1 and 63 (0x3F)
sub
index
1 (0x01) for SSC2 are not recommended for use as they will have a negative influence on the
logic or timer
functions. Using this function will turn an ON delay into an Off delay if it is added for
the SSC1 and SSC2. It is only for the SO1 and SO2.

2.4.7. Application functions
4 unique application functions can be selected via IO-
Link only.
•Speed and Length.
•Pattern Recognition.
•Divider.
•Object and Gap Monitoring.
2.4.7.1.
Speed and Length
This function is designed to monitor the length of an object as well as the speed of a conveyor
belt by means of only two interconnected sensors. The actual value if the length in [mm] and
the speed in [mm/s]are directly available on the IO-Link master.
Either the length or the speed can be set as process data.
2.4.7.1.1. Conditions
Two sensors are needed for this function: a Trigger sensor and a Main sensor.

11) The Speed and length function is now ready for use.
2.4.7.2.
Pattern Recognition
The pattern recognition function is used to verify if a manufactured part has all the e.g. holes
or taps asexpected and that the parts are made according to the specification.
A pattern of a part can be recorded into the sensor and the following parts then
compared
to the pre-recorded pattern.
If pattern match, the sensor will respond with a positive signal or command either as
standalone operationor via an IO-Link master
The pattern can max. contain 20 edges eg. 10 holes or 10 taps.
If multiple pattern are to be detected then several Main sensors can be connected to a single
Trigger sensor.
2.4.7.2.1. Conditions
Two sensors are needed for this function a Trigger Sensor and a Main Sensor, however
several Mainsensors can be connected to the Trigger Sensor ifmore than one pattern must be
examined simultaneously.
Alignment of Trigger and Main
Sensor preparation
1) Mount two sensors at the conveyor in line so the object will reach the two sensors at the
same time.
2) Connect the two sensors to an SCTL55 or IO-Link master

4) Switch on the power to the sensors
5) Restore the sensors to factory settings using the SCTL55 or IO-Link master.
6) Align the two sensors so the light beams will be detecting the edge of the target at the
same time.
7) The trigger sensor must be mounted in a position where it will continuously detect the
object withoutany holes or taps.
8) The Main sensor must be mounted so it detects the taps or holes that contain the
pattern to beexamined
9) Adjust the sensitivity on the sensors to get a reliable detection on the target.

Teach the Pattern
13) Activate the “Teach Pattern” command to start learning the pattern
14) Move the target at a steady speed passing fully by the two sensors
NB! During the measurement variations in the conveyor speed may impact the result.
15) The sensor responds with:
a) “Saved” in “Pattern Recognition Result” -> “Reference Pattern”
b) “E.g. 12” in “Pattern Recognition Result” -> “Reference Pattern No Of Edges”
(counts both theleading and trailing edges of the measurement targets).
c)Each edge is saved in ms from the leading edge of the complete measurement target
and can be found in the Observation menu.When compared to the reference pattern
the edges are normalizedas a percentage value of the complete measurement target.
This ensures that the pattern can be recognized at various constant speeds.
16) The Pattern can be saved as a project in the SCTL55 or IO-Link master and at a later point
send backto the sensor in order to use this specific saved pattern as a reference pattern.
17) The Pattern Recognition function is now ready for use.
18) Move the target again at a steady speed passing fully by the two sensors
19) The Sensor responds with the text
a) “E.g. 12” in “Pattern Recognition Result” -> “Number of Edges Last Pattern”
20) “Patterns Match” in “Pattern Recognition Result” -> “Pattern Recognition Status”
Standalone operation in SIO Mode
21) Disconnect the sensor from the SCTL55 or IO-Link master and connect the Pin 4 to your e.g.
decentralTower light or good/bad conveyor belt
22) Once a valid pattern is detected the Pin 4 output responds with a 1 second pulse.
Multiple patterns
Multiple patterns can be detected simultaneously on the same target using only one Trigger
sensor andmultiple Main sensors each Main sensor responds to a specific Pattern

2.4.7.3.
Divider function
This function allows e.g. the user to set up a number of counts to be performed before
changing the output.
By default, this value is set to 1 and each activation causes the output to
change. When the value is set to
a higher value e.g. 10 then the sensor will give output every
10th detection, the sensor will count at the trailing edge of the object. In the application
example below the sensor shall change the output state after 8
products have been detected.
The sensor output will indicate a “box full” and a new box is moved in front
of the primary
conveyor. The counter can be reset manually via the SO2, pre-configured as an external
reset
button.
2.4.7.3.1. Conditions
Only a single sensor is being used for this function.
