2.1 Main features
IO-Link RS Components 4-wire DC 4th Generation
Tripleshield sensors, built to the highest
quality standards, are available in two different housing sizes.
•M18-cylindrical threaded barrel housing for flush or non-flush installation with 4-pole M12
connectoror 2 metre PVC cable.
•M30-cylindrical threaded barrel housing for flush or non-flush installation with 4-pole M12
connectoror 2 metre PVC cable.
They can operate in standard I/O mode (SIO), which is the default operation mode. When
connectedto 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
additionalconfiguration 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 capacitive 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.
2.3.1 SIO mode
When the sensor operates in SIO mode (default), an IO-Link master is not required. The
device worksas a standard capacitive 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 capacitive 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 orpush-pull, or to add timer
functions such as T-on and T-off delays or logic functions and thereby satisfyseveral
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
automationenvironment.
When the sensor is connected to one IO-Link port, the IO-
Link master sends a wakeup
request (wakeup 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
L+
1
2 4
3
C/Q
L-
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 M12 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 M18 and M30 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 andprocess data.

RS Components Ltd
SIO
IO-Link

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.
2.4 Output Parameters
The sensor measures five different physical values. These values can be independently
adjusted and used as sourceforthe Switching Output 1 or2; inaddition tothose anexternal
inputcanbeselectedfor SO2. After selecting one of these sources, it is possible to configure
the output of the sensor with an IO-Link master, following the 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 thelast configuration setting

2.4.1. Sensor front
When an
object, solid or liquid, approaches the face of the sensor, the capacitance of the
detectingcircuit is influenced and the sensor output changes its status.
2.4.1.1. SSC (Switching Signal Channel)
For presence (or absence of presence) detection of an object in fron
t of the face of the
sensor, the following settings are available: SSC1 or SSC2.
The setpoints can be set from 0 to 10.000 units which represent the change of capacitance
of the detecting circuit. The higher the value, the closer the target appears to the sensing
face of the sensor,
also a higher dielectric value of the target will increase the value. E.g. a
metal target has a higher dielectric value than a plastic target.

2.4.1.4. Dust alarm 1 and Dust alarm 2
The safe limit between when the sensing output is switching and the value at which the
sensor candetect safely even with a slightly build up of dust, can be set.
See 2.6.5 Safe limits.
2.4.1.5. Temperature alarm (TA)
The sensor constantly monitors the internal temperature in the front part of the sensor. Using
the temperature alarm setting it is possible to get an alarm from the
sensor if temperature
thresholds are exceeded. See §2.6.4
The temperature alarm has two separate values, one for setting maximum temperature
and one for setting minimum 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 tointernal heating.
The difference between ambient temperature and internal temperature is influenced by
how the sensoris installed in
the application. If the sensor is installed in a metal bracket the
difference will be lowerthan if the sensor is mounted in a plastic one.
2.4.1.6. External input
The output 2 (SO2) can be configured as an external input allowing external signals to be
fedintothesensor, this can be from a second sensor or from a PLC or directly from machine
output.

2.4.5. Output Inverter
This function allows the user to invert the operation of the switching output between
Normally Open and Normally Closed.
RECOMMENDED FUNCTION
The recommended function is found in the parameters under 64 (0x40) sub index 8 (0x08)
for SO1and 65 (0x41) sub index 8 (0x08) for SO2. It has no negative influence on the Logic
functions or thetimer 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 thelogic 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.

2.6. Sensor Specific adjustable parameters
Besides the parameters directly related to output configuration, the sensor also have
various internalparameters useful for setup and diagnostics.
2.6.1. Selection of local or remote adjustment
It is possible to select how to set the sensing distance by either selecting the Trimmer or
Teach-by-wireusing the external input of the sensor, or to disable the potentiometer to
make the sensor tamperproof.
2.6.2. Process data and variables
When the sensor is operated in IO-Link mode, the user has access tothe cyclic Process Data
Variable.By default the process data shows the following parameters as active: 16 bit
Analoguevalue,SwitchingOutput1 (SO1) and Switching Output 2 (SO2).
The following parameters are set as Inactive: SSC1, SSC2, DA1, DA2, TA, SC.
However by changing the Process Data Configuration parameter, the user can decide to
also enablethe status of the inactive parameters. This way several states can be observed
in the sensor at the same time.

2.6.3. Sensor application setting
The sensor has 3 pre-settings depending on the
•
•
Full scale range, the setpoints of the sensor can be adjusted at full scale and
speed is set to maximum
Liquid level: this is to be used for slow moving objects with a high dielectric value
such as inthe detection of water-based liquids. When this function is selected the
teach and potentiometer settings are optimized to high range scaling.
In this mode the “Filter Scaler” is set to 100
Plastic Pellets: this is to be used for slow moving objects with a low dielectric value
such as inthe detection of plastic pellets. When this function is selected the teach
and potentiometer settings are optimized to low range scaling.
In this mode the “Filter Scaler” is set to 100.

2.6.4. Temperature alarm threshold
The temperature at which the temperature alarm will activate can be changed for the
maximum and minimum temperature. This means that the
sensor will give an alarm if the
maximum or minimum temperature is exceeded. The temperatures can be set between -
50 °C to +150 °C. The default factory settings are, Low threshold -30
°C and high threshold
+120 °C

2.6.5. Safe limits
The sensor has a built-in in safety margin that helps to adjust the sensing up to the set
points
with an
additional safety margin. The factory settings are twice the standard hysteresis of
the sensor e.g. for
a CA19CAN… sensor with a hysteresis of 15% the safety margin is set to
30%.
This value can be set individually from 0% to 100% for SSC1 or SSC2.
2.6.6. Event configuration
Temperature events transmitted over the IO-Link interface are turned off by default in
the sensor. If
the user wants to get information about critical temperatures detected in the
sensor application, this parameter allows the following 3 events to be enabled or disabled:
•Temperature fault event: the sensor detects temperature outside the specified
•
•
•
•
Temperature over-run: the sensor detects temperatures higher than those set in the
TemperatureAlarm threshold.
Temperature under-run: the sensor detects temperatures lower than those set in the
TemperatureAlarm threshold.
Short-circuit: the sensor detects if the sensor output is short-circuited.
Maintenance: the sensor detects if maintenance is needed, e.g. the sensor needs
li
2.6.7. Quality of run QoR
The quality of run value informs the user about the actual sensing performance
compared to the set-points of the sensor: the higher the value the better quality of
detection.
The value for QoR can vary from 0 … 255 %.
The QoR value is updated for every detection
