2. Product
2.1. Main features
IO-Link Carlo Gavazzi 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 to
an SCTL55 or an IO-Link master, they automatically switch to IO-Link mode and can be operated and easily
configured remotely.
Thanks to their IO-Link interface, these devices are much more intelligent and feature many additional 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 functions 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 different
modes: 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 m.

L+
C/Q
L-
IO-Link
SIO
IO-Link communication takes place with a 24 V pulse modulation, standard UART protocol via the switching and
communication 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 PD30CTBxxxBPxxIO 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 temperature 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 replace the device and
automatically have all the information stored in the old device transferred into the replacement unit.

Access to internal parameters allows the user to see how the sensor is performing, for example by reading the
internal temperature.
Event Data allows the user to get diagnostic information such as an error, an alarm, a warning or a communication
problem.
There are two different communication types between the sensor and the master and they are independent of
each 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, Switching
Output1 (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 status
of the inactive parameters. This way several states can be observed in the sensor at the same time.
Process data can be configured. See 2.5.3. Process data configuration.

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.

2.4.1.2. 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.

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 for
PD30CTBS25... and 20 ... 375 mm for the PD30CTBR35... sensor *.
1
* It is not recommended to use settings higher than maximum 200, 250 and 350 mm depending on the sensor
type however under optimal conditions (ambient light environment and EMC noise etc.) the distance can be set
at higher value.

The switching information changes when the distance measured passes the threshold defined in setpoint
SP1. This change occurs only with decreasing distance measured. The switching information also changes
when the distance measured passes the threshold defined in setpoint SP2. This change occurs only with
increasing distance measured. Hysteresis settings stored in the sensor are not applied in this case. The
hysteresis results from the difference between SP1 and SP2.

Foreground suppression Mode
In foreground suppression mode, the sensor is set to detect a background in a predefined distance. If the
background is no longer detected in this predefined distance, e.g. because the reflected light from the
background is blocked by an object, the sensor changes the output state.

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 drop
alarm 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 selector
without using a PLC – making decentralised decisions possible.
The logic functions available are: AND, OR, XOR, SR-FF.
2.4.1.6. External input
The output 2 (SO2) can be configured as an external input allowing external signals to be fed into the
sensor, e.g. from a second sensor or from a PLC or directly from machine output.
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 is
below 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 to
get 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 one
for 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 internal
heating.
The difference between ambient temperature and internal temperature is influenced by how the sensor is
installed in the application.
2.4.1.3. Hysteresis Settings
The hysteresis can be set automatically or manually for SSC1 and manually only for SSC2. The hysteresis is
set 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 “SSC1
Auto hysteresis”, typically 14 mm for PD30CTB.20.., 17 mm for PD30CTBS25... and 24 mm for
PD30CTBR35... for SP1 and SP2.
Manual hysteresis:
When manual hysteresis is selected the hysteresis can be changed between 2 ... 225 mm for 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 the
automatic hysteresis.

RECOMMENDED FUNCTION
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 of
the 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.
2.4.6. Output stage mode
In this function block the user can select if the switching outputs should operate as:
SO1: Disabled, NPN, PNP or Push-Pull configuration.
SO2: Disabled, NPN, PNP, Push-Pull , External input (Active high/Pull-down), External input
(Active low/pull up) or External Teach input.

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.
All application functions are disabled as factory setting.

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.
2.4.7.1.2. Speed and Length – Setup procedure
Sensor preparation
1) Mount two sensors at the conveyor with an individual distance of e.g. 100 mm
2) Connect the two sensors to an SCTL55 or IO-Link master
3) Upload the IODD files in the 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 are parallel to each other and aimed at the target.
7) Adjust the sensitivity on the sensors to get a reliable detection on the object.

b) Select “Sensor role” -> “Trigger Sensor”
c) IO-Link Parameter Set-up is finished for the Trigger Sensor
9) Main sensor: (calculates Speed and Length and makes data available via IO-Link)
a) Reset the sensor using “Restore factory Settings”
(if already performed in point 5 then this can be skipped).
b) Select “Speed and Length” in the SCTL55 or IO-Link master; Menu “Parameter” -> “Application
Functions”
c) Select “Sensor role” -> “Main Sensor”.
d) Enter the distance in between the two sensors in [mm] in the menu “Speed and Length Measurement
Main Sensor” -> “Distance between sensors”
e) Select “Object Length” or “Object Speed” if required in “Process Data” in the “Observation menu”
under “Process data configuration” -> “Analogue value”
i. Object Length will be shown in [mm]
ii. Object Speed will be shown in [mm/s]
10) Connect sensor output Pin 2 of the Trigger Sensor to Input Pin 2 of the Main Sensor
11) The Speed and length function is now ready for use.
NB! During the measurement variations in the conveyor speed may impact the result.
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 as
expected 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 operation
or 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 Main
sensors can be connected to the Trigger Sensor if more than one pattern must be examined simultaneously.
2.4.7.2.2. Pattern recognition – Setup procedure
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
3) Upload the IODD files in the 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 without
any holes or taps.
8) The Main sensor must be mounted so it detects the taps or holes that contain the pattern to be
examined
9) Adjust the sensitivity on the sensors to get a reliable detection on the target.

10) Trigger sensor:
a) Select “Pattern Recognition” in the SCTL55 or IO-Link master; Menu “Parameter” -> “Application
Functions”
b) Select “Sensor role” -> “Trigger Sensor”
c) IO-Link Parameter Set-up is finished for the Trigger Sensor
11) Main sensor:
a) Select “Pattern Recognition” in the SCTL55 or IO-Link master; Menu “Parameter” -> “Application
Functions”
b) Select “Sensor role” -> “Main Sensor”.
c) Enter the Timeout value used for maximum evaluation time between 1 … 60 sec, in the menu
“Pattern Recognition Setup” -> “Timeout” (default value is 60 sec.)
d) Enter the Tolerance of the Pattern in ‰ (Parts per thousand), between 1 and 200 ‰ in the menu
“Pattern Recognition Setup” -> “Tolerance”, default value is 50 ‰
12) Connect sensor output Pin 2 of the Trigger Sensor to Input Pin 2 of the Main Sensor(s)
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 the
leading 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 normalized
as 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 back
to 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. decentral
Tower 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 and
multiple Main sensors, each Main sensor responds to a specific Pattern.
