Installation conditions• Moisture must not penetrate the housing when mounting the device, establishing theelectrical connection and during operation.
• For M12 plug made of metal: Do not remove the protection cap (only in IP69) of M12
plug connection until shortly before electrical connection.
• Do not clean or touch process isolating diaphragms with hard and/or pointed objects.
• Do not remove process isolating diaphragm protection until shortly before installation.
• Always tighten the cable entry firmly.
• Point the cable and connector downwards where possible to prevent moisture fromentering (e.g. rain or condensation water).
• Protect housing against impact.
• For devices with gauge pressure sensor, the following applies:
NOTICE
If a heated device is cooled in the course of a cleaning process (by cold water, forexample), a vacuum develops for a short time causing moisture to penetrate thesensor via the pressure compensation element (1).

Process data

The measuring device has a current output and a switch output. The status of the switch
output is transmitted in the form of process data via IO-Link.
• In the SIO mode, switch output 1 is switched at pin 4 of the M12 plug. In the IO-Link
communication mode, this pin is reserved exclusively for communication.
• The current output at pin 2 of the M12 plug is always active or can be optionallydeactivated via IO-Link.

Bit 31 is reserved. Bit 30 provides the status of the switch output.
Here, 1 or DC 24 V corresponds to the logical "closed" state on the switch output. The
remaining 30 bits contain the analog raw measured value of the device. This value has yet
to be scaled by the target system to the nominal operating range of the existing measuring
device.

Switching signals (with Smart Sensor Profile)

The switching signals offer a simple way of monitoring the measured values for limit
violations.
Each switching signal is clearly assigned to a process value and provides a status. This
status is transmitted with the process data (process data link). Its switching behavior must
be configured using the configuration parameters of a "Switching Signal Channel" (SSC). In
addition to manual configuration for switch points SP1 and SP2, a teach mechanism isavailable in the "Teach" menu. This mechanism writes the current process value to theselected SSC via a system command. The following section illustrates the different
behaviors of the modes available for selection. The "Logic" parameter is always "High active"in these cases. If the logic is supposed to be inverted, the "Logic" parameter can be set to"Low active"().
Single Point Mode
SP2 is not used in this mode.

If block parameter configuration is used, a parameter change is only adopted after theparameter download.

LWARNING
Risk of injury from the uncontrolled activation of processes!
‣ Make sure that downstream processes are not started unintentionally.
LWARNING
If a pressure smaller than the minimum permitted pressure or greater than the
maximum permitted pressure is present at the device, the following messages are
output in succession:‣ S140‣ F270NOTICEAn IODD with corresponding default values is used for all pressure measuring ranges.
This IODD applies to all measuring ranges! The default values of this IODD may not bevalid for this device. IO-Link messages (e.g. "Parameter value above limit") may bedisplayed when the device is updated with these default values. Existing values are
not accepted in this case. The default values apply exclusively to the 10 bar (150 psi)sensor.
‣ Before default values are written from the IODD to the device, the data must first beread from the device.

Example:In this example, a device with a 400 mbar (6 psi) sensor is configured for the measuring
range 0 to 300 mbar (0 to 4.4 psi).
The following values should be assigned:• 0 mbar = 4 mA value• 300 mbar (4.4 psi) = 20 mA value
Prerequisite:
This is a theoretical adjustment, i.e. the pressure values for the lower and upper range are
known. It is not necessary to apply pressure.
Due to the orientation of the device, there may be pressure shifts in the measured
value, i.e. the measured value is not zero in an unpressurized state. For information
on how to perform position adjustment, see the "Performing position adjustment"
section →  31.
For a description of the parameters mentioned and possible error messages, see the"Description of device parameters" section →  46 and →  37.

2.

Select Value for 4 mA (STL) parameter. Enter the value (0 bar (0 psi)) and confirm.
 This pressure value is assigned to the lower current value (4 mA).

3.

Select Value for 20 mA (STU) parameter. Enter the value (300 mbar (4.4 psi)) andconfirm.
 This pressure value is assigned to the upper current value (20 mA).

The measuring range is configured for 0 to 300 mbar (0 to 4.4 psi).

The following values should be assigned:• 0 mbar = 4 mA value• 300 mbar (4.4 psi) = 20 mA value
Prerequisite:
The pressure values 0 mbar and 300 mbar (4.4 psi)can be specified. The device is already

Performing position adjustment

Zero point configuration (ZRO)

Navigation

Parameter → Application → Sensor → Zero point configuration (ZRO)

Description(Typically absolute pressure sensor)
A pressure shift resulting from the orientation of the device can be corrected by the
position adjustment.
The pressure difference between zero (set point) and the measured pressure must be
known.

Prerequisite

An offset is possible (parallel shifting of the sensor characteristic) to correct theorientation and any zero point drift. The set value of the parameter is subtracted from the"raw measured value". The requirement to be able to perform a zero point shift withoutchanging the span is met with the offset function.
Maximum offset value = ± 20 % of the sensor nominal range.
If an offset value is entered that shifts the span beyond the physical limits of the sensor,
the value is admitted but a warning message is generated and displayed via IO-Link. The
warning message only disappears when the span is within the sensor limits, taking theoffset value currently configured into consideration.
The sensor can• be operated in a physically unfavorable range, i.e. outside its specifications, or• be operated by making appropriate corrections to the offset or span.
Raw measured value – (manual offset) = display value (measured value)

Example• Measured value = 0.002 bar (0.029 psi)
• Set the manual offset to 0.002.
• Display value (measured value) after position adjustment = 0 bar (0 psi)
• The current value is also corrected.

Note

Setting in increments of 0.001. As the value is entered numerically, the increment

The pressure value present is automatically adopted as the zero point.
An offset is possible (parallel shifting of the sensor characteristic) to correct theorientation and any zero point drift. The accepted value of the parameter is subtracted
from the "raw measured value". The requirement to be able to perform a zero point shift
without changing the span is met with the offset function.
Maximum offset value = ± 20 % of the sensor nominal range.
If an offset value is entered that shifts the span beyond the physical limits of the sensor,
the value is admitted but a warning message is generated and displayed via IO-Link. The
warning message only disappears when the span is within the sensor limits, taking theoffset value currently configured into consideration.
The sensor can• be operated in a physically unfavorable range, i.e. outside its specifications, or• be operated by making appropriate corrections to the offset or span.
Raw measured value – (manual offset) = display value (measured value)

Example 1• Measured value = 0.002 bar (0.029 psi)
• Use the Zero point adoption (GTZ) parameter to correct the measured value with thevalue, e.g. 0.002 bar (0.029 psi). This means that you are assigning the value
0 bar (0 psi) to the pressure present.
• Display value (measured value) after position adjustment = 0 bar (0 psi)
• The current value is also corrected.
• Where applicable, check and correct switch points and span settings.

Example 2

Sensor measuring range: –0.4 to +0.4 bar (–6 to +6 psi) (SP1 = 0.4 bar (6 psi); STU =0.4 bar (6 psi))• Measured value = 0.08 bar (1.2 psi)
• Use the Zero point adoption (GTZ) parameter to correct the measured value with thevalue, e.g. 0.08 bar (1.2 psi). This means that you are assigning the value 0 mbar (0 psi)to the pressure present.
• Display value (measured value) after position adjustment = 0 bar (0 psi)
• The current value is also corrected.
• Warnings C431 or C432 appear because the value 0 bar (0 psi) was assigned to the realvalue of 0.08 bar (1.2 psi) present and the sensor measuring range was thus exceededby ± 20%.
SP1 and STU values must be readjusted downwards by 0.08 bar (1.2 psi).

Configuring process monitoring

For process monitoring, it is possible to specify a pressure range which is monitored by the
point level switch. Both monitoring versions are described below. The monitoring function
allows the user to define optimum ranges for the process (with high yields etc.) and deploy
a point level switch to monitor the ranges.

9.5.1

Digital process monitoring (switch output), without Smart
Sensor Profile

It is possible to select defined switch points and switchback points which act as NO or NC
contacts depending on whether a window function or hysteresis function is configured.

Behavior of the device in the event of a fault

The device displays warnings and faults via IO-Link. All the device warnings and faults arefor information purposes only and do not have a safety function. The errors diagnosed by
the device are displayed via IO-Link in accordance with NE 107. Depending on the
diagnostic message, the device behaves as per a warning or fault condition. A distinction
must be made between the following types of error here:• Warning:• The device continues measuring if this type of error occurs. The output signal is notaffected (exception: simulation is active).
• The switch output remains in the state defined by the switch points.
• Fault:• The device does not continue measuring if this type of error occurs. The output signal
adopts its fault state (value in the event of an error - see the following section).
• The fault state is displayed via IO-Link.
• The switch output changes to the "open" state.
• For the analog output option, an error is signaled with the configured alarm current
behavior.

10.4

Behavior of the current output in the event of a fault

The behavior of the current output in the event of a fault is regulated in accordance with
NAMUR NE 43.
The behavior of the current output in the event of faults is defined in the following
parameters:• Alarm current FCU "MIN": Lower alarm current (≤3.6 mA) (optional, see the following
table)• Alarm current FCU "MAX" (factory setting): Upper alarm current (≥21 mA)• The selected alarm current is used for all errors.
• Errors and warning messages are displayed via IO-Link.
• It is not possible to acknowledge errors and warnings. The relevant message
disappears if the event is no longer pending.

Description of device parameters

Prerequisite

Cerabar PMP23 IO-Link

An offset is possible (parallel shifting of the sensor characteristic) to correct theorientation and any zero point drift. The set value of the parameter is subtracted from the"raw measured value". The requirement to be able to perform a zero point shift withoutchanging the span is met with the offset function.
Maximum offset value = ± 20 % of the sensor nominal range.
If an offset value is entered that shifts the span beyond the physical limits of the sensor,
the value is admitted but a warning message is generated and displayed via IO-Link. The
warning message only disappears when the span is within the sensor limits, taking theoffset value currently configured into consideration.
The sensor can• be operated in a physically unfavorable range, i.e. outside its specifications, or• be operated by making appropriate corrections to the offset or span.
Raw measured value – (manual offset) = display value (measured value)

Example• Measured value = 0.002 bar (0.029 psi)
• Set the manual offset to 0.002.
• Display value (measured value) after position adjustment = 0 bar (0 psi)
• The current value is also corrected.

Note

Setting in increments of 0.001. As the value is entered numerically, the increment
depends on the measuring range

Description(Typically gauge pressure sensor)
A pressure shift resulting from the orientation of the device can be corrected by the

Prerequisite

The pressure value present is automatically adopted as the zero point.
An offset is possible (parallel shifting of the sensor characteristic) to correct theorientation and any zero point drift. The accepted value of the parameter is subtracted
from the "raw measured value". The requirement to be able to perform a zero point shift
without changing the span is met with the offset function.
Maximum offset value = ± 20 % of the sensor nominal range.
If an offset value is entered that shifts the span beyond the physical limits of the sensor,
the value is admitted but a warning message is generated and displayed via IO-Link. The
warning message only disappears when the span is within the sensor limits, taking theoffset value currently configured into consideration.
The sensor can• be operated in a physically unfavorable range, i.e. outside its specifications, or• be operated by making appropriate corrections to the offset or span.
Raw measured value – (manual offset) = display value (measured value)

Description of device parameters

Example 1• Measured value = 0.002 bar (0.029 psi)
• Use the Zero point adoption (GTZ) parameter to correct the measured value with thevalue, e.g. 0.002 bar (0.029 psi). This means that you are assigning the value
0 bar (0 psi) to the pressure present.
• Display value (measured value) after position adjustment = 0 bar (0 psi)
• The current value is also corrected.
• Where applicable, check and correct switch points and span settings.

Example 2

Sensor measuring range: –0.4 to +0.4 bar (–6 to +6 psi) (SP1 = 0.4 bar (6 psi); STU =0.4 bar (6 psi))• Measured value = 0.08 bar (1.2 psi)
• Use the Zero point adoption (GTZ) parameter to correct the measured value with thevalue, e.g. 0.08 bar (1.2 psi). This means that you are assigning the value 0 mbar (0 psi)to the pressure present.
• Display value (measured value) after position adjustment = 0 bar (0 psi)
• The current value is also corrected.
• Warnings C431 or C432 appear because the value 0 bar (0 psi) was assigned to the realvalue of 0.08 bar (1.2 psi) present and the sensor measuring range was thus exceededby ± 20%.
SP1 and STU values must be readjusted downwards by 0.08 bar (1.2 psi).

Description

Cerabar PMP23 IO-Link

The device displays warnings and faults. This is done via IO-Link using the diagnostic
message stored in the device. The purpose of all device diagnostics is solely to provide
information to the user; they do not have a safety function. The errors diagnosed by thedevice are displayed via IO-Link in accordance with NE 107. In accordance with thediagnostic message, the device behaves as per a warning or fault condition:
Warning (S971, S140, C485, C431, C432):
With this type of error, the device continues to measure. The output signal does not adopt
its fault state (value in the event of an error). The main measured value and the state in
the form of the letter plus a defined number are displayed alternately (0.5 Hz) via IO-Link.
The switch outputs remain in the state defined by the switch points.
Fault (F437, S803, F270, S510, C469 1), F804):
With this type of error, the device does not continue to measure. The output signal adopts
its fault state (value in the event of an error). The fault state is displayed via IO-Link in theform of the letter plus a defined number. The switch output changes to the defined state(open). For the analog output option, an error is also signaled and transmitted via the 4 to
20 mA signal. In NE 43, NAMUR defines a current ≤3.6 mA and ≥21 mA as a device
failure. A corresponding diagnostic message is displayed. Current levels available forselection:
The selected alarm current is used for all errors. Diagnostic messages are displayed withnumbers and letter via IO-Link. It is not possible to acknowledge all the diagnostic

Prerequisite

The following functions are available only if a hysteresis function has been configured forthe switch output (output 1 (Ou1)).

Description of behavior of
SP1/RP1

The hysteresis is implemented using the SP1 and RP1 parameters. Since the parametersettings depend on one another, the parameters are described all together.
The switch point "SP1" and switchback point "RP1" can be defined with these functions (e.g.,
for pump control). When the set switch point "SP1" is reached (with increasing pressure),
an electrical signal change takes place at the switch output. When the set switchback point"RP1" is reached (with decreasing pressure), an electrical signal change takes place at theswitch output. The difference between the value of switch point "SP1" and the value ofswitchback point "RP1" is known as the hysteresis. The configured value for the switch
point "SP1" must be greater than the switchback point "RP1"! A diagnostic message isdisplayed if a switch point "SP1" is entered that is ≤ the switchback point "RP1". While it ispossible to make this entry, it does not take effect in the device. The entry must be
corrected!

Prerequisite

The following functions are available only if a window function has been configured forthe switch output (output 1 (Ou1)).

Description of behavior of

The window function is implemented using the FH1 and FL1 parameters. Since theparameter settings depend on one another, the parameters are described all together.
The upper value of the pressure window "FH1" and the lower value of the pressure window"FL1" can be defined with these functions (e.g., for monitoring a certain pressure range).
When the lower value of the pressure window "FL1" is reached (with increasing or
decreasing pressure), an electrical signal change takes place at the switch output. Whenthe upper value of the pressure window "FH1" is reached (with increasing or decreasingpressure), an electrical signal change takes place at the switch output. The difference
between the upper value of the pressure window "FH1" and the lower value of the pressure
window "FL1" is known as the pressure window. The upper value of the pressure window"FH1" must be greater than the lower value of the pressure window "FL1"! A diagnostic
