4 Function
Measuring cell:
• The system pressure is measured by a ceramic capacitive measuring system.
• The sealing of the ceramic measuring cell is free of elastomers and thus maintenance-free.
• The medium temperature is recorded on the back of the ceramic measuring cell: Accuracy
calculation formula Data sheet.Ò
Signal transmission:
• The unit can be operated in SIO mode (standard input-output ) or in IO-Link mode. The basic
operation mode is SIO. When connected to an IO-Link master, the unit automatically switches to
IO-Link mode. An additional manual switching is not required.
SIO-Mode:
• Analogue signal measured pressure value 4-20 mA (pin 2).
• Switching information (pin 4).
IO-Link mode:
• Measured pressure value
• Measured temperature value
• Exceeding and falling below the limits of the measuring range
• Device status
• Switching information
• Parameter setting
• Device diagnostics (events)
4.1 IO-Link
IO-Link is an internationally standardised IO technology (IEC 61131-9) for communicating with
sensors and actuators.
Further information about IO-Link at: www.io-link.com
IO-Link offers the following advantages:
• Noise-immune transmission of several process values.
• Parameter setting during operation as well as point-to-point at the desk.
• Device diagnostics (events)
• Data storage: Automatic new parameter setting in case of replacement.
• Detection of connected units.
• Freely definable parameters to identify the units in the plant.
Information and documentation on the IO-Link interface at: www.io-link.ifm
4.2 IO-Link properties of the sensor
4.2.1 Description IO-Link interface
A description of the IO-Link interface can be found at www.io-link.ifm
PI100x Electronic pressure sensor
8
The sensor provides the internal unit temperature as a readable parameter for diagnostic purposes.
4.2.2 Internal unit temperature
The internal temperature of the sensor can be read via the IO-Link channel. Measuring range:
-25...155°C (-13...311°F), resolution 1°C (1.8°F), precision +/- 5°C (9°F). Information on measuring
range and accuracy Data sheet.Ò
4.2.3 Counter overpressure events
The unit has a counter for overpressure events. The value above which a pressure is considered to be
overpressure can be set.
• HIPC = Counter overpressure events.
HIPC counts how often the limit HIPS has been exceeded.
The limit must be exceeded for at least 0.5 ms.
• HIPS = Threshold overpressure.
The [HIPC] can be reset with the reset command [Reset_HIPC] and the [Back-to-Box]. See: Reset
sensor / parameter ( 26)Ò/
In case of an interruption of the supply voltage, a maximum of the events of the last 10 minutes
can be lost, as these are summed up in the background and have not yet been permanently
transferred to the memory.
4.2.4 Optical localisation
The sensor can be localised in the plant via the commands [Blinken_An] / [Blinken_Aus]. When the
command is used, the switching status LEDs flash and [IO-L] is displayed.
4.2.5 Event logging
With IO-Link, the sensor has two logging mechanisms:
• Event History (Parameter [Event_History])
• Event Counter (Parameter [Event_Counter])
The last 20 events that occurred are recorded in the event history. As long as no event has occurred,
the value [noEvent] or [0] appears in this list.
The event counter (limited to 232 events) can be used to read how often a specific event has occurred
at the sensor.
The event counter and the event history can be reset using the IO-Link commands
[RESET_EVENT_HISTROY], [RESET_EVENT_COUTER] and [Back-to-Box ].
See: Reset sensor / parameter ( 26)Ò/
4.2.6 Operating hours counter
In the parameter [operating_hours], the hours are counted during which the sensor was active (cannot
be reset).
4.2.7 Switching cycles counters
The sensor counts the switching cycles at output 1 and output 2 in the [OUT_Counter] parameter and
stores this value every full 60 minutes.
A reset is possible with [Reset_to_zero] or the [Back to Box] reset.
See: Reset sensor / parameter ( 26)Ò/

4.3 Defined state in case of a fault
If a fault is detected, the analogue output passes into a defined state ( = 21.5mA).
In case of a fault indication ( = 21.5mA)
uRead parameters via IO-Link or contact the manufacturer.
4.4 Operating modes
The operating mode is defined by the wiring ( Electrical connection) and automatically recognised byÒ
the unit.
4.4.1 2-wire operation
OUT2 (pin 2) Analogue signal proportional to pressure 4…20 mA or 20...4 mA
4.4.2 3-wire operation
OUT1 (pin 4) 2 possibilities (automatic changeover)
• switching signal for pressure limit
• Communication via IO-Link
OUT2 (pin 2) 3 possibilities (manual changeover in the menu)
• switching signal for pressure limit
• Analogue signal proportional to pressure 4...20 mA
• Analogue signal proportional to pressure 20...4 mA
4.5 Switching function (only for 3-wire operation)
OUTx changes its switching status if it is above or below the set switching limits (SPx, rPx). The
following switching functions can be selected:
• Hysteresis function / normally open: [OUx] = [Hno] ( Figure hysteresis function).Ò
• Hysteresis function / normally closed: [OUx] = [Hnc] ( Figure hysteresis function).Ò
First the set point (SPx) is set, then the reset point (rPx) with the requested difference.
• Window function / normally open: [OUx] = [Fno] ( Figure window function).Ò
• Window function / normally closed: [OUx] = [Fnc]( Figure window function)Ò
• The width of the window can be set by means of the difference between SPx and rPx. SPx = upper
value, rPx = lower value.

4.6 Analogue output
The device provides an analogue signal proportional to the pressure. Within the measuring range the
analogue signal is between 4...20 mA. The measuring range is scalable:
• [ASP2] defines at which measured value the output signal is 4 mA.
• [AEP2] defines at which measured value the output signal is 20 mA.
Minimum distance between [ ASP2] and [ AEP2 ] = 20 % of the final value of the measuring
range.
If the measured value is outside the measuring range or in the event of an internal error, the current
signal indicated in the following figure is provided. The analogue signal in case of an error is
adjustable:
• [FOU] = On defines that the analogue signal goes to the maximum value (21.5 mA) in case of an
error.

4.7 Customer-specific calibration
The customer-specific calibration changes the curve of measured values compared to the real
measured values (zero-point calibration and correction of gradient). Keep the following order:
uCarry out zero calibration [coF] in the range -5%....+5% of final value of the measuring range
(VMR).

5.1 Ventilation diaphragm
5.1.1 Function ventilation diaphragm
The ventilation diaphragm enables the relative pressure measurement since barometric and
temperature-dependent pressure fluctuations between the measuring cell and the environment are
compensated for.
The ventilation diaphragm is protected against damage by a screwed filter cover with circumferential
ports.
For a correct functioning of the ventilation diaphragm please take the following into account:
uRemove soiling and cleaning agents immediately using plenty of lime-deficient splash water.
If the sensor is in a cooling stage:
uAvoid contact of the ventilation diaphragm with liquids to avoid negative pressure in the
measuring system (resulting in a slightly falsified measured value) and additional strain on
the diaphragm.
5.1.2 Orientation filter cover
Select the installation situation so that the filter cover is horizontal and the condensate can drain off
due to gravity.

2
uIdeal orientation (1):
The filter cover is in a horizontal position.
wThe ventilation diaphragm (2) in the filter cover is in a vertical
position.
uMaximum inclination of the filter cover: 30° (3)
5.1.3 Replace filter cover
(1) Exchange of the filter cover incl. ventilation diaphragm (E30483).
In difficult environmental conditions or an installation situation that does not correspond to the ideal
alignment (1), the following accessories can be used to protect the ventilation diaphragm:
(2) Replace the filter cover with a closed version (E30148)*.
(3) Replace the filter cover with a version with a tube fitting and a vent tube that ends in a protected and dry area (E30139).
(4) Set of accessories (E30467) with integrated replacement diaphragm (ventilation diaphragm). Recommended for chemically
demanding applications in external cleaning. Function: ( Installation instructions E30467).Ò

uAvoid soiling and moisture during the exchange.
uClean the thread carefully and without residues.
uDo not damage the adhesive surface for the diaphragm on the sensor.
u ÒObserve the orientation of the filter cover ( Installation instructions E30139 / E30467).
*When using the closed filter cover, there is no more pressure compensation of the measuring
cell. This results in measurement deviations caused by:
• Fluctuations of the atmospheric pressure.
• Fluctuations in the internal pressure of the unit with temperature changes.
5.2 Use in hygienic areas according to 3-A
The following applies to units with 3-A certification:
uOnly use adapters with A-3 certification for the process
connection.
uDo not install the unit at the lowest point of the pipe or tank
(position 5) so that the medium can run off the area of the
measuring element.

open [. no] or normally closed [. nc], output off [Off].
• Analogue signal for the current system pressure: 4...20mA [I].
dS1 / dS2* Switch-on delay for OUT1 / OUT2.
dr1 / dr2* Switch-off delay for OUT1 / OUT2.
uni.P Standard unit of measurement for system pressure (display):
[bAr] / [mbar] / [MPA] / [kPA] / [PSI] / [inHG] / [iH2O] / [mmWS].
P-n* Output logic: pnp / npn.
Hi.P Maximum value memory for system pressure.
Lo.P Minimum value memory for system pressure.
FOU1* Behaviour of output 1 in case of an internal fault.
FOU2 Behaviour of output 2 in case of an internal fault.
dAP Damping of the switch point / process data flow (IO-Link communication) and display (Τ63**).
dAA Damping of the analogue output. Requirement: Setting OUT2 is [I] (Τ63**).
coF Zero-point calibration between: -5%...+5% of VMR.

structure); in addition, for some menu items, those parameter values that refer to switching
functions cannot be selected.
9.2 Configure display (optional)
If the unit of measurement [uni.P] has to be changed, this needs to be done before setting other
parameters to avoid internal rounding deviations due to unit conversion.
uSelect [uni.P] and set the unit of measurement:
• [bAr], [mbAr], [MPA], [kPA].
• [psi] (depends on the device).
• [InHO] (depends on the device).
• [mWS] (depends on the device).
• [mmWS] (depends on the device).
[uni.P]
Selectable units of measurement → data sheet.
Uni.P only affects the sensor display. The IO-Link process value remains unaffected.
