9 Commissioning

After power on and expiry of the power-on delay time, the unit is in the normal operating mode. It carries out its measurement and evaluation functions and generates output signals according to the set parameters.

During the power-on delay time, the outputs are in the following status according to the set parameters:

Switching output:

• Active (“high” with normally open function; “low” with normally closed function)

Analogue output:

• 0 mA with current output (I or I_neg )
• 0 V with voltage output (U5, U5 neg , U10, U10 neg )

When an IO-Link master is connected, the device automatically goes from SIO mode (standard input-output) into IO-Link mode if the port of the master is set to IO-Link mode.

Notes on parameter setting → Manual of the parameter setting software

10.3 Output configuration

10.3.1 Digital switching signal

The device provides digital switching signals via switching signal channels (SSC = Switching Signal Channel).

The device has two digital switching signal channels SSC1.1 and SSC1.2 which can be used to output the process value.

Explanation of the numbering of the switching signal channels SSCx.y:

x = process value; y = switching signal channel

The switching channels can be analysed via the IO-Link interface and the hardware output.

The switching signal channel SSC1.1 is permanently assigned to the physical hardware output OUT1.

The switching signal channel SSC1.2 can only be read via the IO-Link interface.

The parameters for each switching signal channel can be set individually.

The switch point mode, switch points and the switch point logic are set when the switching signal channel parameters are set.

Switch point mode

You can choose between the following switch point modes according to the IO-Link smart sensor profile – Function Class “Object Detection”:

• [Deactivated]
  • [Single Point Mode]
• [Two Point Mode]
• [Window Mode]

The switching signal channel changes to the active state depending on the process data value (PDV).

The active state is above the switch point in [Single Point Mode] and [Two Point Mode] and within the window section in [Window Mode].

Switch point logic

By setting the switch point logic [High active] or [Low active], you can specify which value the switching signal channel has in the active state:

• [High active]: The switching signal channel is "high" in the active state (= ON = normally open = 1)
• [Low active]: The switching signal channel is "low" in the active state (= OFF = normally closed = 0)

The following figures show the status of the switching signal channels depending on the switch point mode, switch point logic and process data value (PDV).

Deactivated

If the [Deactivated] switch point mode is set for a switching signal channel, then the switching signal channel will permanently have the following value regardless of the process value:

• For switch point logic [High active]: permanently "low".
• For switch point logic [Low active]: permanently "high".

Fig. 23: [Deactivated] / [High active]

Fig. 24: [Deactivated] / [Low active]

Single Point Mode

Only one switch point (SP1) is manually set or taught.

The reset point (SP1-H) results from the switch point and the set hysteresis.

When teaching, the switch point is set below the taught process value (TP1) by the hysteresis.

SP1-H Reset point

For devices with a negative measuring range to zero (vacuum devices PQxxx9 with measuring range -1 bar...0 bar), the following applies in contrast to all other devices: The switch point logic is factory preset to [Low active].

Two Point Mode

One switch point SP1 and one switch point SP2 are manually set or taught.

When parameter setting via IO-Link, the position of the switch points can be freely selected: SP1 can be below or above SP2. The lower switch point is the reset point. In the example shown, SP1 is the switch point and SP2 is the reset point.

When parameter setting via the device keys, SP1 must be greater than SP2.

When teaching, the switch point is set directly to the taught process value. The following applies: [Teach SP1] sets SP1, [Teach SP2] sets SP2.

The hysteresis will be ignored in Two Point Mode.

Fig. 28: [Two Point Mode] / [Low active]

SP1: Switch point 1

SP2: Switch point 2

TP1: Teach point 1 (= SP1)

TP2: Teach point 2 (= SP2)

For devices with a negative measuring range to zero (vacuum devices PQxxx9 with measuring range -1 bar...0 bar), the following applies in contrast to all other devices: The switch point logic is factory preset to [Low active].

Window mode

Two switch points (SP1) and (SP2) are manually set or taught.

The two switch points define a window area.

The position of the switch points is freely selectable: SP1 can be below or above SP2. The lower switch point is the lower limit value, the higher switch point is the upper limit value of the window area.

When teaching, the switch point is set directly to the taught process value. The following applies: [Teach SP1] sets SP1, [Teach SP2] sets SP2.

When the process data value enters the window area, the status of the switching signal channel changes immediately when the switch points are exceeded/not reached.

If the process data value leaves the window area, the status of the switching signal channel changes when the switch point plus hysteresis (SP1+H or SP2-H) is exceeded/not reached.

The hysteresis must be no greater than 10% of the final value of the measuring range. If this means that the set and reset points are not far enough apart for the application in [Single Point] mode, the [Two Point] mode should be selected.

If the [Auto] setting is chosen for the hysteresis, the following value will be set for the hysteresis:

Measuring range	Hysteresis [Single Point]	Hysteresis [Window]
-1...0 bar	0.02 bar	0.002 bar
-1...1 bar	0.04 bar	0.004 bar
-1...10 bar	0.2 bar	0.02 bar
0...16 bar	0.32 bar	0.03 bar

10.3.2 Analogue signal

The device provides an analogue signal proportional to the process value.

The analogue signal can be provided as current or voltage signal.

Besides, the analogue signal can be inverted (e.g. I = 4...20 mA and I_neg = 20...4 mA).

The analogue signal is set via the parameter [ou2] ( → see table).

The parameters [ASP2] and [AEP2] allow for the measuring range to be limited:

• [ASP2] = analogue start value = measured value at which the analogue signal ① is provided.
• [AEP2] = analogue end value = measured value at which the analogue signal ② is provided.

Minimum distance between [ASP2] and [AEP2] = 20 % of the final value of the measuring range.

Setting for [ou2]	1	2	Analogue signal in case of a fault
I	4 mA	20 mA	>21 mA
Ineg	20 mA	4 mA	<3.6 mA
U5	1 V	5 V	>5.25 V
U5neg	5 V	1 V	<0.75 V
U10	0 V	10 V	>11 V

Changing the unit has no effect on the IO-Link process value, which is always transmitted in the SI unit.

Selectable values:

• Pressure:
• PQx6x0 and PQx6x2 = MPa, bar, psi, inHg, mmHg, kgf/cm ²
• PQx6x6 = kPa, mbar, psi, inHg, mmHg, kgf/cm²

10.7.3 Binary data transmission (BLOB)

The device offers a function for reading binary data from the device as one large file (BLOB = Binary Large Object).

The data is exported as a CSV file.

This requires a software tool (e.g. ifm moneo) that supports the IO-Link BLOB interface.

The CSV file contains the following logbook information:

• device information for identification
• number of operating hours
- event logging:

– event history with time stamp
- event code
- event description
- event frequency
- device restarts

Only the last 50 events are saved.

In case of a voltage interruption, the events of the last 10 minutes can be lost.

10.7.3.1 Export binary data

The following section describes the parameter setting procedure using ifm moneo. If other software is used, the parameter setting procedure can differ.

√ The [Configure devices] view is open.
√ The connection to the device has been established.
√ The parameter value editor for the device is open.
√ The device supports the BLOB function.

▶ Click on ⓞ in the vertical bar at the right side of the screen.
▶ Select the [File transfer (BLOB)] tab.
▶ From the [Selected function] list, select the desired BLOB function.
▶ Execute command: [Export data from device].
▶ Click [Save file] and select file name and file path.
▷ moneo saves the selected data on the PC.

10.7.4 Optical localisation

The sensor can be located remotely in the system via the IO-Link interface.

When the command is used, the LEDs will flash and ⬇ [IO-Link] will flash on the display.

▶ Select [Identification].
▶ Execute command: [Locator Start].
▶ To end the flashing process: Execute command: [Locator Stop].

The flashing can also be stopped by pressing any key on the device.

10.7.5 Lock / unlock

The unit can be locked electronically to prevent unauthorised setting.

This lock prevents the settings from being changed via the keys on the unit.

Factory setting: not locked.

10.7.5.1 Parameter setting via unit keys: lock / unlock

Locking:

▶ Make sure that the unit is in the normal operating mode.
▶ Press [▲] and [▼] simultaneously for 10 s until [Loc] is displayed.
▷ The device is locked for parameter setting via the device keys. When trying to change a parameter value, the symbol ☐ appears in the display.

The locking can only be removed via the device keys. Changing the parameter setting is still possible via the IO-Link interface.

Unlocking:

▶ Make sure that the unit is in the normal operating mode.
▶ Press [▲] and [▼] simultaneously for 10 s until [uLoc] is displayed.
▷ The locking of the device keys is removed.

10.7.5.2 Parameter setting via IO-Link: lock / unlock

▶ Make sure that the unit is in the normal operating mode.
▶ Select [Parameter] > [Other settings].
▶ Select [Device Access Locks. Local User Interface] and set [Locked].
▷ The device is locked for parameter setting via the device keys. When trying to change a parameter value, the symbol ☐ appears in the display.

The locking can be removed via the IO-Link parameter [Unlocked].

10.7.6 Reset the device

The device can be reset in two ways.

With both reset applications, the operating hours since the first set-up are not reset.

[APPL] = application reset

The following is reset:

• All changed application-specific parameters

If IO-Link data storage is activated, this triggers a parameter update in the master. This writes the parameters configured in the master to the device again. An application reset may therefore be ineffective.

[BtB] = Back to Box

The following is reset:

• All changed application-specific parameters
- All writeable unit identification parameters such as [Application Specific Tag], [Function Tag] or [Location Tag].
• Diagnostic parameters, status parameters, events.
• Number of switching cycles
• Minimum and maximum memory value for pressure

After the Back to Box reset, the sensor suspends communication and measurement operation until the voltage is interrupted. The IO-Link data storage is not triggered.

10.7.6.1 Parameter setting via unit keys: reset the unit

▶ Select [EF] > [rES].
▶ Select [APPL] or [BtB] and set [Yes].

Only if [BtB] is selected:

▶ Disconnect and reconnect the voltage supply.

▷ The device carries out a reboot.

10.7.6.2 Parameter setting via IO-Link: reset the unit

▶ Select [Parameters] > [Basic settings].
▶ Execute command: [Application reset] or [Back to Box].
Only if BtB is selected:
▶ Disconnect and reconnect the voltage supply.
▷ The device carries out a reboot.

11 Operation

After power on and expiry of the power-on delay time, the unit is in the normal operating mode. It carries out its measurement and evaluation functions and generates output signals according to the set parameters.

Use the device keys to view additional information during operation:

▶ Press the [▲] or [▼] key repeatedly.
▷ The display alternates between different screens.
▷ After 30 seconds, the device returns to the user-defined display layout.
