Switch Output Configuration

The sensor measures five 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 following the steps that are shown in the Switching Output
configuration (Figure 3

Once the sensor has been disconnected from the master, it switches to the SIO
mode and keeps the last configuration setting.

Hysteresis

Sensor Front When an object (solid or liquid) approaches the face of the sensor, the

capacitance of the detecting circuit is influenced and the sensor output
changes its status.

SSC (Switching Signal Channel)

For presence (or absence of presence) detection of an object in front of the face
of the sensor, the following settings are available: SSC1 or SSC2.

The setpoints can be set from 0…10,000 units that represent the change of
capacitance of the detecting circuit. The higher value, the closer the target
appears to the sensing face of the sensor, also a higher dielectric value of the
target increases the value. For example, a metal target has a higher dielectric
value than a plastic target.

Switchpoint Mode

The switchpoint mode setting can be used to create more advanced output
behavior. The following switchpoint modes can be selected for the switching
behavior of SSC1 and SSC2.

Mode Description

Disabled

Single-point mode

Two-point mode

SSC1 or SSC2 can individually be disabled, which also disables the output if it is
selected in the input selector (the logic value is always 0).

The switching information changes, when the measurement value passes the
threshold that is defined in setpoint SP1, with rising or falling measurement values,
considering the hysteresis.

The switching information changes when the measurement value passes the threshold
that is defined in setpoint SP1. This change occurs only with rising measurement
values. The switching information also changes when the measurement value passes
the threshold that is defined in setpoint SP2. This change occurs only with falling
measurement vales. Hysteresis is not considered in this case.

Hysteresis Settings

In SSC1 and SSC2 - single point mode and in windows mode the hysteresis can
be set 1…100% of the actual switching value.

(SP2 + Hysteresis < SP1) & (SP1 + hysteresis < Sensing range upper limit)

Margin Alarm 1 and 2

The safe limit between when the sensing output is switching and the value at
where the sensor can detect safely even with a slight buildup of dust can be set.

Temperature Alarm (TA)

The sensor constantly monitors the internal temperature in the front part of
the sensor. With the temperature alarm setting, it is possible to get an alarm
from the sensor if temperature thresholds are exceeded.

The temperature alarm has two separate values, one for setting the maximum
temperature and one for setting the minimum temperature.

It is possible to read the temperature of the sensor via the acyclic IO-Link
parameter data.

External Input

The output 2 (SO2) can be configured as an external input that allows external
signals to be feed into the sensor from a second sensor, a PLC, or directly from
machine output.

Input Selector This function block allows you to select any of the signals from the sensor front

to the Channel A or B.

Channel A and B: Can select between SSC1, SSC2, margin alarm 1, margin
alarm 2, temperature alarm, and external input.

Logic Function Block In the logic function block, the selected signals from the input selector can be

added a logic function directly without using a PLC - which makes decentral
decisions possible.

The logic functions available are AND, OR, XOR, and gated SR-FF.

Output Inverter This function allows you to invert the operation of the switching output

between normally open and normally closed.

IMPORTANT

The recommended function is found in the parameters under 64 (0x40)
sub index 8 (0x08) for SO1 and 65 (0x40) sub index 8 (0x08) for SO2 does
not have any negative influence on the Logic functions or the timer
functions of the sensor as it is added after those functions.

ATTENTION: We do not recommend using the Switching logic function that is
found under 61 (0x3D) sub index 1 (0x01) for SSC1 and 63 (0x3D) sub index 1
(0x01) for SSC2 as they have a negative influence on the logic or timer
functions.
For example, this function turns an ON-delay into an OFF-delay as it is added
for the SSC1 and SSC2 and not only for the SO1 and SO2.

Output Stage Mode In this function block, you can select how the switching outputs operate:

• SO1: Disabled, NPN, PNP, or Push-Pull configuration.

• SO2: Disabled, NPN, PNP, Push-Pull, External input (Active high/Pull­down), External input (Active low/pull up), or External Teach input.

External Teach (Teach-by-wire)

Chapter 4

Teach Procedure

IMPORTANT

The Teach-by-wire must be first configured with an IO-Link master:

1. Select 2=Teach by wire in the Selection of local/remote adjustment
parameters 68 (0x44).

2. Select 1=Single Point Mode is already selected in SSC1 Configuration
61(0x3D), “Mode 1” 2(0x02) (this value should already be set as default).

3. Select 6=Teach-In (Active High) in Chanel 2 (SO2) 65 (0x41) sub index 1
(0x01).

Teach-by-wire Procedure

This function works in single point mode and only for SP1 in SSC1.

1. Place the target in front of the sensor and connect the teach-by-wire
input (pin 2 white wire) to V+ (pin 1 Brown wire). The yellow status
indicator flashes at a 1 Hz rate (ON 100 ms and OFF 900 ms).

2. Within 3…6 seconds the wire must be disconnected, and the yellow status
indicator flashes at a 1 Hz rate (ON 900 ms and OFF 100 ms).

3. After a successful teach, the yellow status indicator flashes at a 2 Hz rate
(ON 250 ms and OFF 250 ms).

IMPORTANT If the Teach procedure is to be canceled, do not remove the wire after

3…6 second. Keep the connection for 12 sec until the yellow status
indicator flashes at a 10 Hz rate (On 50 ms and off 50 ms).

Teach from IO-Link Master To enable teach from IO-Link master, first disable the trimmer input:

1. Select 0=Disabled in the Selection of local/remote adjustment
parameters 68 (0x44).

2. The individual team commands can be written to index 2.

Single-point Mode Procedure

Select the Switching channel to be taught:

1. Select: 1=SSC1 or 2=SSC2 in the Teach-in Select 58(0x3A) or 255 = All SSC.

2. Change the Hysteresis if requested for SSC1 or SSC2.

Sensor-specific Adjustable Parameters

Besides the parameters that are directly related to output configuration, the
sensor also has various internal parameters useful for setup and diagnostics.

Local or Remote Adjustment Selection

It is possible to select how to set of the sensing distance by either select the
Trimmer, Teach-by-wire using the external input of the sensor, or to disable
the potentiometer to make the sensor tamper-proof.

Process Data and Variables When the sensor is operated in IO-Link mode, you have access to the cyclic

Process Data Variable.

By default the process data shows the following parameters as active: 16-bit
Analog value, Switching Output1 (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, you can also
decide to enable status of the inactive parameters. This way several states can
be observed in the sensor at the same time.

Sensor Application Setting The sensor has three presets depending on the application:

Preset Description

Full scale range

Liquid level

Plastic pellets

Rockwell Automation Publication 875-UM001A-EN-P - March 2021 29

The setpoints of the sensor can be adjusted at full scale and the sensing speed are set to
maximum.

This preset is used for slow-moving objects with a high dielectric value such as 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.

This preset is used for slow-moving objects with a low dielectric value such as 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.

Chapter 5 Sensor-specific Adjustable Parameters

Temperature Alarm Threshold

The temperature where the temperature alarm activates can be changed for
the maximum and minimum temperature. This setting means that the sensor
gives an alarm in the maximum or minimum temperature is exceeded. The
temperatures can be set between -50…+150 °C (-58…+302 °F). The default
factory settings are:

• Low threshold = -30 °C (-22 °F)

• High threshold = +120 °C (+248 °F)

Safe Limits The sensor has a built-in safety margin that helps adjust the sensing up to the

setpoints with an additional safe margin. The factory settings are set to two
times the standard hysteresis of the sensor.

Event Configuration Temperature events that are transmitted over the IO-Link interface are turned

off by default in the sensor. If you want to get information about critical
temperatures detected in the sensor application, this parameter allows you to
enable or disable the following events:

Event Description

Temperature fault event The sensor detects temperature outside specified operating range.
Temperature over-run The sensor detects temperatures higher than set in Temperature Alarm threshold.
Temperature under-run The sensor detects temperatures lower than set in Temperature Alarm threshold.
Short-circuit The sensor detects if the sensor output is short-circuit.
Maintenance The sensor detects if maintenance is needed like the sensor need cleaning.

Quality of Run (QoR) The quality of run value informs about the actual sensing performance

compared to the setpoints of the sensor (the higher the value, the better quality
of detection). The value for QoR can vary to any value from 0…255%. The QoR
value is updated for every detection cycle.

Chapter 5 Sensor-specific Adjustable Parameters

Quality of Teach (QoT) The quality if teach value informs about how well the actually teach procedure

was done, meaning the margin between the actual setpoints and the
environmental influence of the sensor. The value for QoT can vary to any value
from 0…255%. The QoT value is updated after every teach procedure.

• Short-term reliability and maintenance are expected due to environmental conditions.

• Reliable detection can be expected with restricted environmental influence.
Poor teach result.

• Not reliable working sensing conditions are expected (for example, too small of a measuring
margin between the target and the surroundings).

Filter Scaler This function can increase the immunity towards unstable targets and

electromagnetic disturbances. The value can be set from 1…255, the default
factory settings is 1. A filter setting of 1 gives the maximum sensing frequency
and a setting of 255 gives the minimum sensing frequency.

Status Indication This parameter allows you to disable status indication in the sensor if you do

not want the status indicators to illuminate in your application.
