4 Functionality
4.1 Communication, parameter setting, evaluation
• The unit generates output signals according to the parameter settings�
• Using an IO-Link capable parameter setting tool such as the FDT service
program ifm Container the following options are available:
- Reading current process values�
- Reading, changing and saving current parameter settings and transmitting
them to other units of the same type�
The catalogue of the available DTM objects, the IO-Link Unit Description
(IODD) and the FDT service program ifm Container can be downloaded at
www.ifm.com→Service→Download.
4.2 Operating modes
1
2-wire temperature transmitter
The unit provides a temperature-proportional output signal (4���20 mA or 20���4 mA)�
Themeasuringrangeisscalable→4.4Analoguefunction.
In addition, the analogue output for diagnosis can be used according to NAMUR
NE43� Since the diagnostic output is not available in this operating mode, it is not
possible to display all error states of the unit�
2
Temperature transmitter with diagnostic output (3-wire operation)
In addition to the analogue signal the unit provides a diagnostic signal� Sensitivity and
reaction to different error modes can be programmed�
Pin 4 = output for diagnostic signal (pnp or npn)�
3
Communication mode (3-wire operation)
The sensor is designed for communication with the PC or PLC via IO-Link� For com-
munication with a PC, the FDT service program ifm Container is available�
For communication mode, no parameter setting is necessary� Using pin 4 (data chan-
nel), data can be read in and out at any time�

6
4.3 Monitoring and diagnostic functions
• By measuring with two different, thermically coupled sensor elements (NTC,
PT 1000) the unit automatically detects drifts and errors during temperature
measurement with great reliability�
• An average value is formed from the measured individual NTC and Pt 1000
values� This average value is the basis for the provided measured value and
also the basis for the drift warning threshold [drW], the drift alarm threshold
[drA] and the drift failure threshold [drF] derived from the drift alarm threshold�
• If one of the two sensor elements fails, the temperature measurement can be
continued with the second element (backup function)�
• Very long-term stable measurement is achieved by using high-quality sensor
elements�
4.3.1 Drift / fault monitoring
To monitor the drift the unit compares the temperatures of two different sensor ele-
ments that are thermically coupled in the sensor tip� Normally these temperatures
are identical�
Due to the usual manufacturing tolerances a temperature difference of max� 0�1 K
can also occur with new sensor elements� This does not affect the drift monitoring
function�
If there is a drift in one or both sensor elements, the unit detects them due to the
difference between the two measured temperatures� It compares the average
value of the two temperatures with the set warning / alarm thresholds [drW], [drA]
→7.2.4;→7.2.5.
If the thresholds are exceeded, it generates corresponding diagnostic messages
and sets the corresponding status for the process value�
In case of high temperature changes in the measured medium (e�g� filling of a
hot medium into a cold vessel) there may be a short-term difference between the
temperatures of both measuring elements� To suppress this effect, the delay can
be changed via the parameter [ddr]�
4.3.2 Sensor backup / redundancy switching
If one of the two temperature measuring channels fails (e�g� short circuit of one of
the two sensor elements), the temperature can still be measured with the channel
which is still operational (sensor backup)� However, drift monitoring is not possible
any more�

mentsisdefinedbytheparameter[drEd]→8Operation.
4.4 Analogue function
• [OU2] defines whether the set measuring range is provided as 4���20 mA
([OU2] = [I]) or as 20���4 mA ([OU2] = [InEG])�
• The analogue start point [ASP] defines at which measured value the output
signal is 4 mA (20 mA for [InEG])�
• The analogue end point [AEP] defines at which measured value the output
signal is 20 mA (4 mA for [InEG])�
Minimum distance between [ASP] and [AEP] = 5 K�

4.4.1 Behaviour in case of exceeding or not reaching the limits of the meas-
uring range
• Measured temperature above the set measuring range (AEP):
- The output signal rises to max� 20�5 mA / falls to min� 3�8 mA�
- If the measured temperature rises any further, a message may be signalled to
thecontrollerdependingonthesettingofthemenuitem[drEd](→8Opera-
tion)�
• Measured temperature below the set measuring range (ASP):
- The output signal falls to min� 3�8 mA / rises to max� 20�5 mA�

4.5 Operating mode: 2-wire temperature transmitter
4.5.1 Availability groups in 2-wire operation [drEd]
Using [drEd] it can be set which recognised diagnosis types can be passed on via
the current output (setting via FDT service program)�

4.5.2 Setting of the analogue value in case of diagnosis [FOU2]
In 2-wire operation there is a diagnostic message when the actual process value
is no longer provided but instead a defined current value to Namur NE43� Two
settings are available:

4.6 Operating mode: 3-wire temperature transmitter with dia-
gnostic switching output
4.6.1 Availability groups in 3-wire operation [drEd]
Types of diagnostic to be signallled via the current or diagnostic switching output
can be set using [drEd] (setting via FDT service program)�
Since in 3-wire operation all diagnostic messages can be transferred via
the switching output, the current output only leaves its process value trans-
fer in case of a failure� This ensures maximum use of the analogue output�
