• The system architect undertakes to perform a risk assessment and to create documentation in accordance with legal and normative requirements to be provided to the operator and user of the system. This documentation must contain all necessary information and safety instructions for the operator, the user and, if applicable, for any service personnel authorised by the architect of the system.

• Read this document before setting up the product and keep it during the entire service life.

• The product must be suitable for the corresponding applications and environmental conditions without any restrictions.
• Only use the product for its intended purpose (→ Intended use).
• If the operating instructions or the technical data are not adhered to, personal injury and/or damage to property may occur.
• The manufacturer assumes no liability or warranty for any consequences caused by tampering with the product or incorrect use by the operator.
• Installation, electrical connection, set-up, operation and maintenance of the product must be carried out by qualified personnel authorised by the machine operator.
• Protect units and cables against damage.

3 Intended use

The unit detects metal without contact and signals this by means of a switching signal.

In addition, the unit provides a linearised distance value with a resolution of 12 bits via the IO-Link interface.

4 Function

The sensor has 2 outputs, OUT1 and OUT2, of which OUT2 can be used as a digital input. This offers the following functionalities, for example, depending on the application:

Fig. 1: function

1. OUT1 and OUT2 are both used as switching outputs.
2. OUT1 is used as an IO-Link interface and OUT2 as a switching output.
3. OUT1 is used as a switching output and OUT2 as a digital input for an external signal. See Input configuration ( → ☐ 12).

Both outputs can also be deactivated.

The switching signal channels SSC1 and SSC2 as well as the counters S1CT and S2CT can be set separately.

Using the parameter setting software, the switching signal channels and counters can be freely assigned to the outputs OUT1 and OUT2.

4.1 Switching function with switch point

A switching signal can be provided for process value monitoring. OUTx will change its switching status according to the parameter settings as a function of the distance to the object.

You can choose between the following switch point modes according to the IO-Link smart sensor profile:

• Single point mode
• Two point mode
• Window mode

Term	Explanation
H	Hysteresis, can be set via the parameter [HY]
High active	Switch-point logic:switching output is switched on object detection = NO (normally open)
Low active	Switch-point logic:switching output is not switched on object detection = NC (normally closed)
PDV (Process data variable)	Process data value
SP	Switch point (SP1 must be greater than SP2)
SSC (Switching Signal Channel)	Switching signal channel
SSC1	Switching signal channel 1 (output signal, either via OUT1 or OUT2)
SSC2	Switching signal channel 2 (output signal, either via OUT1 or OUT2)
Single point mode	Single switch point mode
Two point mode	Two switch point mode
Window mode	Window mode

Tab. 1: definition of terms

Single point mode

Only one switch point (SP1) is manually set or taught. The switch-off point results from the switch point and the set hysteresis (H).

Single point mode – low active
SP1+H: switch-on point
SP1: switch-off point

Single point mode – high active
SP1: switch-on point
SP1+H: switch-off point

Two point mode

A switch point (SP1) and a switch-off point (SP2) are manually set or taught.

Two point mode – low active
SP2: switch-off point
SP1: switch-on point

Two point mode – high active
SP1: switch-off point
SP2: switch-on point

Window mode

Two switch points (SP1) and (SP2) are manually set or taught. The two switch points delimit a window area.

Window mode – low active
- The output switches off (low active) within the switching limits SP1 and SP2.
- The output switches on (high active) when the process value leaves the window area and the set hysteresis is exceeded: SP1+H or SP2-H.

Window mode – high active
- The output switches on (high active) within the switching limits SP1 and SP2.
- The output switches off (low active) when the process value leaves the window area and the set hysteresis is exceeded: SP1+H or SP2-H.

See also: Configure switching outputs ( → ☐ 14).

4.2 Switching function with counter

The unit saves the number of switching cycles at both switching signal channels SSC1 and SSC2 using the switching cycles counters S1CT and S2CT.

The counter value can be read via the IO-Link interface.

The counter saves the switching cycles every 5 minutes. Switching cycles since the last save operation are lost in case of a voltage interruption.

When a set switching cycle threshold is reached, the switching status changes, and when the IO-Link interface is used, a data bit is set. The status change is valid for a defined hold time.

See also: Configure counters ( → 16).

The counter can be reset via an IO-Link command or a trigger edge at the digital input, or it is reset automatically when the switching cycle threshold is reached.

See also: Reset counters ( → 17).

7 Parameter setting

The parameters are set via the IO-Link interface on pin 4 using the parameter setting software.

In addition, when using pin 2 as a digital input, the following settings can also be triggered via an input signal:

• switch point teach
• reset of switching cycles counters
  • optical localisation of the sensor via a flashing LED
• configure switching signal channel for OUT1 / switch-point logic

See also: Input configuration ( → ☐ 12).

Parameters can be set before installation or during operation.

If you change parameters during operation, this will influence the function of the plant.

▶ Ensure that there will be no malfunctions in your plant.

During parameter setting the unit remains in the operating mode. It continues to monitor with the existing parameter until the parameter setting has been completed.

Requirements for parameter setting via the IO-Link interface:

√ A suitable parameter setting software, e.g. ifm moneo|configure
√ The Input Output Device Description (IODD) for the device, see documentation.ifm.com
√ One IO-Link master
▶ Connect the IO-Link master to a parameter setting software.
▶ Set the port of the master to the IO-Link operating mode.
▶ Connect the device to a free port of the IO-Link master.
▷ The unit switches to IO-Link mode.
▶ Change parameter settings in the software.
▶ Write parameter settings to the unit.

Notes on parameter setting → Manual of the parameter setting software

7.1 Input configuration

The digital input enables the sensor to be controlled without an IO-Link master.

OUT2 is set as a digital input via the parameter setting software. The input signal can be provided through a trigger edge (e.g. pushbutton) or a static high/low signal (e.g. switch). The input signal changes the current function and operating principle of the sensor.

Via the input configuration, the conditions for the input signal and the sensor function to be triggered can be set using the parameters [DIn2] and [DIF2].

[DIn2]	[DIF2]	Sensor function
+EDG: rising trigger edge-EDG: falling trigger edge	D_IN_DEFAULT_IDLE	Factory setting: no function
	D_IN_BLINK_TOGGLE	Optical localisation
	D_IN_TEACH_SP1	Teach switch point 1	For the taught switch point, the set switch point mode, switch-point logic and hysteresis values apply.
