1.1. Description
RS Components photoelectric sensors are devices designed and manufactured in
accordance with IEC international standards and are subject to the Low Voltage (2014/35/EU)
and Electromagnetic Compatibility
(2014/30/EU) EC directives.
All rights to this document are reserved by RS Components Ltd, copies may be made for
internal use only Please do not hesitate to make any suggestions for improving this document
1.2. Validity of documentation
This manual is valid only for 2377276 and 2377277 photoelectric sensors with IO-Link and
until
new documentation is published.
1.3. Who should use this documentation
This instruction manual describes the function, operation and installation of the product for its
intended use. This manual contains important information regarding installation and must be read
and completely understoodby specialized personnel dealing with these photoelectric sensors.
Wehighly recommend that you read the manual carefully before installingthe sensor. Save the
manual for futureuse. The Installation manual is intended for qualified technical personnel.
1.4. Use of the product
These photoelectric diffuse reflective sensors are designed with Background Suppression, meaning
it is detecting the object via triangulation. The reciver is a detector array that performs precise
detection independentof the colour of the object and allows elimination of a background.
The received signal level can be read via the Process data in IO-Link mode.
The 2377276 and 2377277 sensors can operate with or without IO-Link communication. By means
of an IO-Link master it is possible to operate and configure these devices.
1.5. Safety precautions
This sensor must not be used in applications where personal safety depends on the function of the
sensor (The sensor is not designed according to the EU Machinery Directive).
Installation and use must be carried out by trained technical personnel with basic electrical
installation knowledge. The installer is responsible for correct installation according to local safety
regulations and must ensure that
a defective sensor will not result in any hazard to people or
equipment. If the sensor is defective, it must be replaced and secured against unauthorised use.

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.

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.
