6 User Manual
You can download the technical description file (IODD) required for using the pressure
transmitter in the download area of the LABOM website (www.labom.com).
6.1 View in configuration tool
Different entries in the menue structure are possible depending on the configuration tool.
The four areas below are standardised across tools and contain all important parameter
and setting functions:
- Identification, see 6.2
- Parameter, see 6.3
- Observation, see 6.4
- Diagnosis, see 6.5
Outlined below are the detailed menue contents as structured in PACTware 4.1. Other IO-
Link tools have a different parameter structure or display them differently, although the
functionality is identical.
6.2 Menue "Identification"
The parameters displayed here identify the product and manufacturer.
Figure 2: "Identification" menue in PACTware 4.1

BA_083 Rev 1C9 Digital transmitter for temperature IO-Link Page 7/24
6.3 Menue "Parameter"
In this area, the device is parametrised. The individual parametrisation options are outlined
below.
6.3.1 Section "Measurement / Output"
In this section, the process data format, pressure unit and damping are parametrised.
Figure 3: Section „Parameter – Measurement / Output“ in PACTware 4.1
6.3.1.1 Process data format
The process data format is used to set the number format in which the measuring value is
transmitted.
In the format “floating point”, the measuring value is transmitted as a floating point number.
In the format “integer”, the measuring value is transmitted as an integer number. The two
lowest digits represent two decimal places. E.g. the integer number 199 represents the
measuring value 1.99 (in terms of the current unit).
6.3.1.2 Unit temperature
This is where the temperature measuring unit can be set. This is used as basis when
transmitting the temperature value as part of the process values. Additionally, all parame-
ters with a temperature reference refer to this unit.
Please note that parameters with a temperature reference are not converted automatically
when the unit settings are changed. Example: The zero point offset of 0.1 is saved in the
unit ‘°C’. If the unit is changed to °F, the zero point offset is now at 0.1 °F.
This affects the parameters for adjustment (see 6.3.2) and the switching points (see 6.3.3)
as well as the min/max values (see 6.5.2).
That is why the temperature unit should be parameterised first. After changing the temper-
ature unit, please check the parameters with a temperature reference and reset the
min/max values.

6.3.1.3 Damping
Adjusting the damping function within the range of 0.00 to 100.00 s, avoids that rapid
measured value fluctuations or spikes (input values) are visible in the output signal.
Damping is achieved by a 2nd order digital filter for which the time is set in seconds.
After that set time, 26% of the change in the input value is visible in the output signal. After
the set time has elapsed 4 times, approximately 90% of the change is visible in the output
signal.

6.3.2 "Adjustment" section
In this section, the measuring device can be calibrated and thus optimises measuring ac-
curacy.
6.3.2.1 Sub-section "Temperature correction"
Figure 5: Section „Parameter – Temperature correction“ in PACTware 4.1
In terms of temperature correction, a temperature offset is entered, which acts as the off-
set across the entire measuring span. You can therefore enter it at any reference tempera-
ture you wish.
Expose the instrument to the required reference temperature and read out the temperature
value measured by the instrument (see also 6.4). Now enter the difference using the re-
versed algebraic sign as temperature offset and transfer the value to the instrument.
Please note that the temperature offset value is not displayed in the tool immediately, only
after the device parameter is retrieved again.

BA_083 Rev 1C9 Digital transmitter for temperature IO-Link Page 10/24
6.3.2.2 Sub-section "Adjustment of characteristic curve"
Figure 6: Section "Parameter - Adjustment of characteristic curve" in PACTware 4.1
This feature allows to correct the characteristic curve of the temperature transmitter. In
contrast to temperature correction, the adjustment of the characteristic curve allows to
change the offset and the gradient.
Follow the process below to perform the adjustment of characteristic curve:
1. Apply the lower (as low as possible) reference pressure level to the measuring device
2. Enter the lower target value in the field “Target value lower adjustment point” and trans-
fer it to the device.
3. Press the button “Set actual value to lower adjustment point”. This sets the current ac-
tual value as “actual value lower adjustment point”.
4. Apply the upper (as low as possible) reference pressure level to the measuring device
5. Enter the upper target value in the field “Target value upper adjustment point” and
transfer it to the device.
6. Press the button “Set actual value to upper adjustment point”. This sets the current ac-
tual value as “actual value upper adjustment point”.
7. Activate the adjustment by setting the parameter “Enable adjustment of characteristic
curve” to “on”.
The adjustment of characteristic curve can be performed with any reference temperatures.
For instance, the lower adjustment point of a -40…150 °C device at 0 °C. You can also
choose any reference temperature for the upper adjustment point. However, to achieve a
precise adjustment, the reference values should be as close as possible to the lower and
upper range value.

BA_083 Rev 1C9 Digital transmitter for temperature IO-Link Page 11/24
Please note that the actual values for the lower and upper adjustment points are not dis-
played immediately after the corresponding buttons are pressed in the tool, but only after
the device parameters are retrieved again.
Please note that the values for the adjustment of characteristic curve refer to the set unit
and that this unit is not converted automatically when changes are made (also see
6.3.1.2).
To deactivate the adjustment, set the parameter “Enable adjustment of characteristic
curve” to “off”.
The values for the “Actual/Target lower adjustment point” and “Actual/Target upper ad-
justment point” are kept, but ignored.

BA_083 Rev 1C9 Digital transmitter for temperature IO-Link Page 12/24
6.3.3 Section "Switching outputs"
This section describes how to parametrise switching outputs.
Figure 7: Section „Parameter – Switching outputs“ in PACTware 4.1
The IO-Link signal can also be used as switching output 1, whereas the switching output 2
signal is available at all times. If switching output 1 is activated, an IO-Link master can be
connected although. The pressure transmitter identifies the master automatically after
start-up and disables switching output 1 in order to respond to the master IO-Link commu-
nication. As a result, parameterising is possible at all times without the need to disable
switching output 1 first.
The “Switching outputs” section contains the entries for the first and second switching out-
put in consecutive order. The parameter function partly depends on whether a hysteresis
or frame function is selected. The delay switch point and delay reset point can be para-
metrised for both functions.

BA_083 Rev 1C9 Digital transmitter for temperature IO-Link Page 13/24
The following parameters are available:

Delay reset point 0 to 100 s Delay time at reset point
Output function PNP/High-side or
NPN/Low-side
Setting of output driver see table 1
Table 3: Switch output parameters
Please note that the switch point refers to the set unit and that this unit is not converted
automatically when changes are made (see 6.3.1.2).
The switch point must be selected between the end of the nominal range and the reset
point. In turn, the reset point must be selected between the start of the nominal range and
the switch point.
You can define delays for the switch point as well as the reset point, e.g. to avoid that
short temperature peaks trigger the switch.

tion
Hysteresis, normally open If the measured value is above the switch point the switch is
closed. At the lower range limit the switch is open.
Hysteresis, normally closed If the measured value is above the switch point the switch is
open. At the lower range limit the switch is closed.
Frame, normally open Inside of the frame the switch is closed. At the lower range
limit the switch is open.
Frame, normally closed Inside of the frame the switch is open. At the lower range limit
the switch is closed.

6.3.4 Section "Diagnostics configuration"
This section describes how to configure the device's diagnostic events.
Figure 10: Section „Parameter – Diagnostics configuration“ in PACTware 4.1
6.3.4.1 Sub-Section "Events"
Up to four specific IO-Link events can be activated for pressure transmitter diagnostics:
−Process data invalid: The process data are invalid. The measuring value contains
an error code which describes the cause in more detail. Also see 6.5.1.1.
−Upper temperature limit exceeded: The value exceeded the upper range value
−Lower temperature limit exceeded: The value has fallen below the lower range val-
ue
−Device failure: Defect in the adjustment data and/or hardware defective (sensor
broken, sensor shorted)
Also see Chapter 7.2 Error detection.

BA_083 Rev 1C9 Digital transmitter for temperature IO-Link Page 16/24
6.3.5 Section "System"
In this section, you can reset all parameters to factory settings and reset the min/max val-
ues.
Figure 11: Section „Parameter – System“ in PACTware 4.1
Pressing the button “Restore Factory Settings” resets all parameters in the sections
“Measurement / Output”, “Adjustment”, “Switching outputs” and “Diagnostics configuration”
to their factory settings.
The buttons "Reset temperature min/max" can be used to reset the temperature min/max
values to the current temperature independently from each other.

BA_083 Rev 1C9 Digital transmitter for temperature IO-Link Page 17/24
6.4 Menue "Observation"
In this section, you can monitor the process values (current values). The values are dis-
played according to the structure outlined in Chapter 7.1.

6.5.1 Section "Process values"
This is where errors in the measuring value and status byte flags are indicated.
6.5.1.1 Error codes in the measuring value
Severe errors are indicated by very high measuring values. This corresponds to the princi-
ple of an alarm current of a 4...20 mA interface.
The error codes depend on whether the measuring value is transmitted as a floating point
or as an integer number (see 6.3.1.1).
The following error codes have been defined:
Error Floating point Integer number
Lower temperature limit exceeded 1,0 × 10

Table 5: Error codes in the measuring value
6.5.1.2 Error flags in status byte
The error flags in the status byte can either have the status “true” or “false”. In this context,
“true” means that the error specified actually occurred.
The following error flags have been defined:
−“Process data invalid“: This is the same as the event “Process data invalid”. Value
has exceeded upper temperature limit or has fallen below lower temperature limit
−“Parameter memory defective”: Check sum error in the parameter section
−“Device failure”: Check sum error in the adjustment data section, sensor broken or
short-circuited
6.5.2 Section "Min/Max values"
This is where the min/max measuring values since the last reset are displayed (see 6.3.5).
6.5.3 Section "Device status"
This section is where the diagnose data for the device status are summarised. This in-
cludes
−Operation hours counter
−Error counter: Increases whenever an event occurs
−Device status: According to the IO-Link specification
−Detailed device status: According to the IO-Link specification

BA_083 Rev 1C9 Digital transmitter for temperature IO-Link Page 20/24
The device status can have the following values according to the IO-Link specification:
−0: No error
−2: Outside the specification (low voltage)
−4: Downtime
