►Finish parameter setting, install (→ 6), connect (→ 8) and set up the unit�

4 Functions and features

The unit detects the medium temperature and provides the measured value via an

analogue and/or a digital signal�

5

UK

The unit features an integrated diagnostic function and a calibration check function

(→ 5.4.1)� The diagnostic messages are provided via an analogue signal or a

switching signal or as a digital communication signal via the IO-Link interface�

The unit has an LED that indicates deviations from normal operation via a colour

change (→ 5.4.2)�

5 Function

• The unit has an IO-Link interface�

• The unit is designed for three-wire operation� The following output signals are

available:

OUT1 (2 options):

- diagnostic signal

- IO-Link signal for temperature measurement and diagnostics

OUT2:

- analogue signal for temperature measurement and diagnostics

5.1 IO-Link

This unit has an IO-Link communication interface which enables direct access to

process and diagnostic data� In addition it is possible to set the parameters of the

unit while it is in operation� Operation of the unit via the IO-Link interface requires

an IO-Link master�

With a PC, suitable IO-Link software and an IO-Link adapter cable communication

is possible while the system is not in operation�

The IODDs necessary for the configuration of the unit, detailed information about

process data structure, diagnostic information, parameter addresses and the

necessary information about the required IO-Link hardware and software can be

found at www�ifm�com�

6

The IO-Link interface provides the following functions:

• Remote parameter setting of the unit�

• Noise immune process value transmission without measured value losses�

• Transmission of the parameter settings to other units of the same type or when

the unit is replaced�

• Simultaneous reading of the two temperature values (measuring element and

reference element), the diagnostic output (calibration check function) and the

device status�

• Paperless logging of parameter sets, process values and diagnostic

information�

5.2 Diagnostic signal

The diagnostic output is only used to provide warnings and alarms (→ data sheet

for the maximum nominal current of the switching output)�

The switching output is closed in normal operation (normally closed)� If the unit

detects a diagnostic case, the output opens�

The switching logic (PnP/nPn) and the calibration check limit (ccL) from which the

output switches can be set�

The diagnostic messages are defined and cannot be changed (→ 12)�

5.3 Analogue signal

The unit converts the measured temperature value into a temperature-proportional

analogue signal�

In addition the analogue output is used for diagnostics (→ 5.4 Diagnostic function)�

The transmission of the measured temperature value is interrupted for alarms

and an analogue signal according to NE43 of 3�5 mA (FOU2 = OFF) or 21�5 mA

(FOU2 = On) is provided� In case of warnings, the analogue signal continues to be

provided�

Depending on the parameter setting (→ 9) the analogue signal for values within

the measuring range is:

4��20 mA with setting [OU2] = I or

20��4 mA with setting [OU2] = Ineg�

7

UK

The measuring range is scalable:

• [ASP] defines at which measured temperature value the analogue signal is 4

mA (OU2 = I) or 20 mA (OU2 = Ineg)�

• [AEP] defines at which measured temperature value the analogue signal is

20 mA (OU2 = I) or 4 mA (OU2 = Ineg)�

Minimum distance between [ASP] and [AEP] = 5 K�

If the measured temperature value is outside the scaled measuring range, the

analogue signal is 20...20.5 mA or 3.8...4 mA (→ Fig.1). When the measured

temperature value continues to increase or decrease, the analogue signal goes to

the value 3�5 mA or 21�5 mA�

5.4 Diagnostic function

The unit continuously checks the temperature measurement (→ 5.4.1 Calibration

check function) and detects further events� In case of deviations from normal

operation, a diagnostic message is provided (→ 5.4.2)�

5.4.1 Calibration check function

By measuring with two different, thermically coupled sensor elements (measuring

element and reference element) the unit automatically detects temperature

differences during temperature measurement�

The process value is measured by the measuring element and provided via the

analogue output�The reference value is used for comparison purposes and to

verify the process value� If the temperature difference between the process value

and the reference value exceeds the value set as calibration check limit [ccL], a

warning is triggered: The LED changes to blue and the diagnostic output opens�

T [°K]

CCL

Figure 2: Calibration check function

Example: Measuring element (1) measures 61�05 °C, reference element (2) measures 60 °C�

Setting ccL = 1 K results in a warning�

If a warning is triggered, the LED remains blue, even if the temperature

difference drops below the ccL value again� Corrective measures:

Check whether the sensor is to remain in use in the process or to be

replaced or do as follows:

►Increase the ccL value so that the LED goes back to green�

> The diagnostic output closes�

> The ccL modification is written to the logbook (→ 5.6)�

If the reference element fails, the calibration check function fails as well and

the LED changes to blue�

9

UK

Setting range ccL →Technical data.

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

calibration check function�

To ensure that the calibration check function detects no other influences

except the temperature difference between the sensor elements, an internal

delay time of 10 minutes has been set�

5.4.2 Diagnostic messages

Diagnostic messages are output as follows:

• LED signal:

The LED shows all warnings and alarms by means of a colour change

(blue = warning; red = alarm)�

• Diagnostic signal:The diagnostic output provides all warnings and alarms via a

switching signal�

• Analogue signal:The analogue output only provides alarms�In case of an alarm

the analogue signal goes to 3�5 mA or 21�5 mA�

• IO-Link:If the IO-Link interface is used, all diagnostic messages are displayed

via the connected software or provided to the higher-level controller� In

addition, a diagnostic bit is provided that corresponds to the behaviour of the

physical switching output�
