4.3 Operating principle

Inductive sensors are used for the contactless and wear-free detection of metallic objects. To
do this, the devices generate an electromagnetic field which interacts with the detected object.
The sensors of the uprox® series have no reduction factor; the switching distance is the same for
all metals.

4.4 Functions and operating modes

The devices can be operated in IO-Link mode or in standard I/O mode (SIO mode). The devices
must be connected to an IO-Link master for operation in IO-Link mode.
IO-Link mode provides bidirectional IO-Link communication between an IO-Link master and
the sensors. For this the devices are integrated in the controller level via an IO-Link master.
The switching signals of the sensors are made available with the process data via the IO-Link
interface. Besides the switching information, diagnostics and identification messages can also
be queried via IO-Link.
Different sensor functions can be configured via the IO-Link interface.

4.4.1 Sensor functions

“One switch point”

The output configuration and the switching behavior can be set for one switch point. Switching
distance (in 20 % increments) and hysteresis are adjustable. With the “One switch point” func­tion, output 2 can be used as a temperature indicator.

12

Hans Turck GmbH & Co. KG | T [phone] | F [phone] | [e-mail] | www.turck.com

Product description

“Two switch points”

Switching output 1 and switching output 2 can be used and set to separate switching distances
in 20% increments. A variable hysteresis cannot be set for the “Two switch points” function.

“Low resolution analog mode”

NOTE

The low resolution analog mode can only be used in operation on an IO-Link master.

In low resolution analog mode the switching states are sampled sequentially in 20% incre­ments. This provides distance information which is output via Bit 2…Bit4 of the process data in
binary format.

NOTE

Output 2 can be configured as required or can be used as a temperature indicator. The
maximum switching frequency is reduced to 7 Hz in low resolution analog mode.

“Rotational speed monitor”

The “Rotational speed monitor” enables the device to detect frequency values below and above
a specified frequency window. Upper and lower limit values of the frequency window can be
set between 0 and 30000 pulses per minute. The switching behavior is described in Fig. 6.

“Pulse divider”

The “Pulse divider” function causes the device to output a signal pulse to the control level after
a specified number of actuation pulses. The number of actuation pulses (divider) can be set
between 1 and 128.
The following values can be set for the minimum duration of the signal pulse:

■

Target object ( 0 ms)

■

1 ms

■

10 ms

■

Switching distance

NOTE

The feature is only available for “One switch point” and “Two switch points” functions.

The switching distance can be set for both outputs to 20 %, 40 %, 60 %, 80 % and 100 % of the
maximum rated switching distance. Different switching distances can be set independently of
each other for output 1 and output 2. The switching distance of output 1 must be greater than
the switching distance of output 2; otherwise the switching distance for switching output 1
is set automatically to 20 % greater than the switching distance for switching output 2. If the
device automatically changes the switching distance for switching output 1, this is indicated by
a request for a new data update.

Product description

Switching hysteresis

NOTE

The switching hysteresis setting is only available for the “One switch point” function.

The switching distance hysteresis can be set to the 2 stages “Standard” and “small”.

NOTICE

“Small” hysteresis selected

Uncontrolled changing between the switching states

 Set the switching distance and target in the application so that a setting to “small”

hysteresis is possible.

Switch-on delay

NOTE

The switch-on delay can only be set for the “One switch point” function.

If the switch-on delay Ton is activated, the switching pulse is generated after the actual sensor
actuation. The switch-on delay can be set between 0…60000 ms.

Abb. 7: Switch-on delay

The set output configuration is not changed. Switching pulses that are shorter than the set
switch-on delay are not transferred to the controller.

Switch-o delay

NOTE

The switch-off delay can only be set for the “One switch point” function.

If the switch-off delay T

off

is activated, the generation of the switch signal pulse is delayed by

the set time after sensor actuation.

Abb. 8: Switch-off delay

The set output configuration is not changed. Interruptions in switch pulses that are shorter
than the set switch-off delay are ignored at the output and are transferred with a switching
signal to the controller.

uprox® Sensors with IO-Link Interface

Temperature indicator

NOTE

The temperature indicator does not provide a highly precise value and does not show
the exact ambient temperature.

The device is provided with an integrated temperature indicator. The actual internal sensor
temperature can be read via the acyclic IO-Link parameter data. The application specific limit
values “Alarm undertemperature” and “Alarm overtemperature” can be set within the permis­sible temperature range. Values below and above the limit values are transferred to the control­ler via bit 6 and bit 7 of the process data. The acyclic parameter data enables the set limits to be
read out.
The temperature unit can be set to °C, °F or K. A temperature alarm can be set at output 2 for all
functions apart from the “Two switch points” function in SIO mode. The device switches when
the actual value is above or below the set limits.

Application specic marking

The device is provided with a 32 byte memory for application specific marking. The first byte of
the memory is transferred to the controller level via bit 8…bit 15 of the cyclic process data; up
to 256 devices can be identified via the process data. The acyclic parameter data enables the
memory to be completely read out.

Alternating oscillator frequency

NOTE

The “Alternating oscillator frequency” feature is only available for devices suitable for
non-flush mounting.

An alternating oscillator frequency reduces the lateral installation constraints between two
adjacently mounted devices. The alternating oscillator frequency is denoted as “F2” in the IODD.

LED mode

The LED settings can be adjusted as follows:

■

Only operating voltage indication: UB (green), output (yellow)

■

Only switching state: Output (yellow)

■

Off

LED temperature indication

The green LED can indicate values above or below the set temperature limits with a 1 Hz flash
signal. Both LEDs on the rectangular devices flash green.

Product description

Start delay

NOTE

The “Start delay” function can only be set for the “Rotational speed monitor” function.

If the start delay is active, the switching signals are passed on to the controller once with a time
delay after each interruption of the power supply. The start delay can be set between 0…60000
ms. Output 1 and output 2 are switched during the set start delay, bit 5 of the process data is
set here to 1. The start delay bridges the start time of drives in order to prevent the output of
unwanted fault messages from the higher-level controller due to low speeds.

4.4.3 Standard I/O mode (SIO mode)

In standard I/O mode devices can be operated via a fieldbus device or a controller with digital
PNP, NPN or push-pull inputs. An IO-Link master is not required.

In SIO mode the device has 2 switching outputs. The following IO-Link communication cannot
be used:

■

Binary coded switching state information in low resolution analog mode

■

Temperature alarm for values above or below the set temperature limits

■

Application specific marking

■

Reading of IO-Link parameter data
All other sensor functions and settable features (see chapt. 4.4.1 and see chapt. 4.4.2) can be
used in SIO mode. The set functions can be evaluated via the switching signals of the particular
output.
Parameter changes made via IO-Link are also retained in the device after saving and after the
power supply is interrupted. Devices can be set via IO-Link and then operated at the digital
inputs with the appropriate settings in SIO mode.

4.5 Technical accessories

The following optional accessories are available for connection and parameter setting. Informa­tion on mounting accessories is provided on the relevant product data sheets. Accessories are
not supplied with the device.

7 Commissioning

The device is operational automatically 18 ms after the cables are connected and the power
supply is switched on. If the device is connected to an IO-Link master, IO-Link communication
starts automatically. For this the IO-Link master sends a wakeup request to the device.

7.1 Setting IO-Link mode

 Set a cycle time of at least 8 ms on the IO-Link master.
 The device is operational.

7.2 Setting up SIO mode

 Connect the device to a standard I/O port.
 The device is operational after a delay of 500 ms.

The delay is necessary in SIO mode for the operation of preactuated sensors so that the sensor
can exclude being connected to an IO-Link master. The operation delay has no effect on any
potential IO-Link communication.

Operation

8 Operation

8.1 LEDs

The devices are provided with a green and a yellow status LED.

NOTE

The switching state of the device is only indicated via the LEDs in SIO mode. In IO-Link
mode the green LED flashes (1 s on, 0.1 s).

LED indication Meaning

green flashing (1 s on, 0.1 s off) IO-Link communication

green Device is operational

yellow Switching output 1 actuated

yellow flashing (approx. 1Hz) Switching output 2 actuated

yellow flashing (approx. 4Hz) Temperature indicator

green/yellow flashing Fault in SIO mode

8.2 Operating devices in IO-Link mode

IO-Link mode provides different sensor functions and adjustable features. The bidirectional
IO-Link communication enables all the parameters to be changed by the controller during com­missioning as well as during operation.

NOTE

The change of the output configuration is only updated after a voltage reset or after
switching to SIO mode.

8.3 Operating devices in SIO mode

In SIO mode the device operates according to the last setting made in IO-Link mode. Not all
sensor functions and settable features of the device are available for use in SIO mode. The fol­lowing functions can be set as standard:

■

“One switch point” sensor function

■

Output 1: PNP (NO contact), output 2: PNP (NC contact)

■

Switching distance: 100 %

■

Both LEDs on

9 Setting

The device has two outputs which can be set independently of each other. Output 1 can be
operated either as a switching output or as an interface for IO-Link communication, output 2 is
designed as a switching output.

9.1 Setting via IO-Link

The devices can be parameterized via the IO-Link communication interface within the limits of
their technical specifications (see data sheet). For further information on IO-Link see the IO-Link
commissioning manual (D900634).

9.1.1 IO-Link parameters

Different parameter settings for the particular application are made via the IO-Link interface.
For further information on the functions and IO-Link parameters see chapter 4.4.1 and the IO­Link parameter manual of the device.

9.1.2 Parameter transfer with IO-Link call function block

Due to the range of functions available with the devices, the parameter subindexes described
in the IO-Link parameter manual cannot be addressed with an IO-Link call function block com­pliant with the IO-Link specification. To transfer parameters the entire data string of the param­eter index must be transferred in binary format from the controller to the device. The subindex
“0” referring to the entire string must be set in the IO-Link call function block. A separation of
subindexes is not possible.

9.1.3 Process data

Bit Function Meaning/bit information

0 Output 1 0: Output 1 not actuated

1: Output 1 switches (depending on the sensor function
and the output configuration)

1 Output 2 0: Output 2 not actuated

5 Start delay 1: Start delay switched on and activated after a voltage

reset (for “Rotational speed monitor” sensor function)

6 Undertemperature 1: Temperature indicator detects value below the set tem-

perature limits

7 Overtemperature 1: Temperature indicator detects value above the set tem-

perature limits

8…15 Application specific marking A 32 byte memory is provided for application specific

marking. The first byte of the memory is transferred cycli­cally to the controller.

If the sensor is actuated, bits 0…4 show the switching state according to the actual settings.

Example: “One switch point” sensor function, 100% switching distance, output 2 not set as a
temperature indicator.

Troubleshooting

9.2 Setting in SIO mode

Various sensor functions and settable features (see chapt. 4.4.1 and see chapt. 4.4.2) can be
used in SIO mode. The set functions can be evaluated via the switching signals of the particular
output.

9.2.1 Setting the device before initial commissioning

 Set the sensor functions and features via an IO-Link master or IO-Link USB adapter (see chap-

ter 4.5) using a configuration tool.

 The selected settings are saved and are available after the device is mounted in the

installation.

9.2.2 Setting devices after initial commissioning

 Disconnect the device from the controller.
 Set the sensor functions and features via an IO-Link master or IO-Link USB adapter using a

configuration tool.

 The selected settings are saved and are applicable after the device is refitted in the

installation.

10 Troubleshooting

 If possible use the device at another location in the application.

The sensor has a fault if it is still present.

 Take the device out of service and replace it with one of the same type.

If the device operates trouble-free at the different location in the application, the fault is caused
by the application.

 Check the environment of the device for metallic foreign objects in the metal free zones.
 Check the environment of the device for EMC interference sources.

11 Maintenance

The good condition of the sensor connections and cables must be checked regularly.
The devices are maintenance-free, clean dry if required.
