2. Product
2.1. Main features
IO-Link RS Coponents 4-wire DC photoelectric Time Of Flight “TOF” sensors, built to the highest quality
standards,are available in two different housing materials.
•Plast ABS. IP67 approved
•Stainless Steal AISI316L for harsh environment. IP69K and ECOLAB approved.
They can operate in standard I/O mode (SIO), which is the default operation mode. When
connected to 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 in solving decentralized 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), an IO-
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 di
gital inputs (standard I/O
port). One of the greatest benefits of thesephotoelectric sensors is the possibility to configure them
via an IO-Link master and then, once disconnected, 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 ind
ustrial
automation environment. When the sensor is connected to one IO-Link port, the 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 startsautomatically 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 2377271, 2377272, 2377274 and 2377275 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 toadvanced functionalities, allowing the settings and configuration to be changed
during operation, and enablingdiagnostic 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

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.
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.
Process data can be configured See 2 6 3 Process data configuration
4 Bytes
Analogue value 16 … 31 (16 BIT)
2.4. Output Parameters
The sensor measur
es four different physical values. 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 an IO-Link master, followingthe six 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 TOF sensor measure the distance to object by emissing small pulses of IR-laser light and then
measure thetime for the light, reflected by an object, to return to the sensor.
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 areavailable: SSC1 or SSC2. Setpoints can be set from 10 ... 2000 [mm]*.
* It is not recommended to use settings higher than maximum 1000 mm however under optimal
conditions(object surface, ambient light environment and EMC noise etc.) the distance can be set
at higher value
2.4.1.2. Switchpoint mode:
Each SSC channel can be set operate in 3 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 measurement value passes the threshold defined
in setpoint
SP1, with rising or falling measurement values, taking into consideration the
hysteresis

Two point mode
The switching information changes when the measurement value passes the threshold defined
in setpoint SP1. This change occurs only with rising measurement values. The
switching
information also changes whenthe measurement value passes the threshold define
d in setpoint
SP2. This change occurs only with falling
measurement values. Hysteresis is not considered in this
case

2.4.1.3. Hysteresis Settings
Range 5 ...2000. Hysteresis unit is mm.
Hysteresis can manually be set for
Point Mode or Window Mode for both SSC1 and
independent
However SSC1 has an extra feature, Automatic hysteresis. Automatic hysteresis supports Single
Point Modeand Windows Mode.
Use parameter “SSC1 Hyst Mode” to choose between Manuel/Automatic hysteresis.
Note: When trimmer is selected, hysteresis is always Automatic.
Automatic hysteresis:
Automatic hysteresis will guarantee stable operation for most application.
Hysteresis is calculated with reference to SP1/SP2. Actual values can be read via parameter
“SSC1 Autohysteresis value”.
Manuel hysteresis:
For application that require a hysteresis other than the automatic, the hysteresis can be
configured manually.This features 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. Temperature alarm (TA)
The sensor constantly monitors the internal temperature. Using the temperature alarm setting it is
possible toget an alarm from the sensor if temperature thresholds are exceeded. See §2.6.5.
The temperature alarm has two separate values, one for setting maximum temperature and
one for settingminimum temperature.
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.
2.4.1.5. External input
The output 2 (SO2) can be configured as an external input allowing external signals to be
fed into thesensor, this can be from a second sensor or from a PLC or directly from machine
