3 Intended use
The device is used for the evaluation of an analogue signal (4...20 mA) from a connected sensor or
another device with analogue output (4...20 mA). The device has one analogue current input and two
outputs: output 1 (digital) and optionally output 2 (analogue current output).
The unit is not suited for environments with particular requirements on mechanical stability (e.g.
shock/vibration).
The unit is intended for indoor use only.
uObserve the operating conditions (Ò Technical data at www.ifm.com).

4 Function
There are basically two modes in which the device can be operated:
• As stand-alone device
The device compares the measured current value with the set parameters and switches its output
according to the selected parameters. This mode is without IO-Link functionality. The parameters
can, however, also be set with an IO-Link tool.
• As IO-Link device
The device operates as an “analogue/IO-Link converter”. The evaluation of the measured current
value depends on the parameters which are set with IO-Link tools or a PLC via IO-Link
communication or directly on the device.
In some points parameter setting via IO-Link tools or PLC is different from parameter setting via
the menu (Ò Parameter setting).
4.1 Use as a stand-alone device without IO-Link
The device compares the measured current value with the set parameters and switches its output
according to the selected function (Ò Operation).
The measured value is shown on the alphanumerical display. The displayed value can be scaled by
the user (2-point scaling).

4.2 Application as an IO-Link device
4.2.1 General information
The unit has an IO-Link communication interface which requires an IO-Link capable module (IO-Link
master).
The IO-Link interface allows direct access to the process and diagnostic data and enables setting of
the parameters of the unit during operation.
You will find further information about IO-Link and all the necessary information about the required IO-
Link hardware and software at:

measured value is also displayed.
Additionally, the device converts the measured current and transmits the value via IO-Link connection
to the PLC.

8 Menu
8.1 General
Irrespective of the operating mode (standard IO mode or IO-Link device) there are two options to set
the parameters of the unit:
• directly on the device via the menu (Ò Parameter setting)
• or via an IO-Link tool
Access via an IO-Link tool has a higher priority than parameter setting via the menu.
Parameter cloning and parameter setting backup is possible with an IO-Link tool.
Some parameters can only be set via the IO-Link interface:
Parameters adjustable via IO-Link.
If the device was locked via IO-Link, it can also only be unlocked via the IO-Link interface:
Locking / unlocking (Ò/22).
The scaling parameter [ScAL] only influences the display and not the transferred process data or the
actual switching threshold values.
Via IO-Link, the current value is always transmitted in μA → Representation of the measured current
value (Ò/13). The switching thresholds can be set in steps of 0.01 mA.
If a scaling is set, the menu settings of the switching thresholds (SP, rP etc.) are also scaled.
Via IO-Link, however, the settings continue to be displayed and executed in steps of 0.01 mA
(resolution 10 bits).

8.4.2 A.Trm ─ analogue termination for OUT2
• [OFF] = OUT2 is externally connected, e.g. to the analogue input of another device.
• [On] = OUT2 is not connected and the current path is terminated internally.
Note the following for proper current measurement and evaluation:
If the internal analogue termination is set to [On], output OUT2 must not be connected.
8.4.3 ou1 ─ output function for OUT1

• [Hno] = hysteresis function / normally open

8.4.4 dS1/dr1 ─ switching delay/switch-off delay for OUT1
Value: 0.0...50.0 s (0.0 = delay time is not active)
8.4.5 ScAL ─ scaling of the displayed value
The setting acts like a multiplier for the parameters [C.ASP]/[C.AEP].
• [OFF] = measured current value is not scaled.
• [cccc] = scaling without decimal place (x 0001).
• [ccc.c] = scaling with 1 decimal place (x 000.1).
• [cc.cc] = scaling with 2 decimal places (x 00.01).
• [c.ccc] = scaling with 3 decimal places (x 0.001).
8.4.6 C.ASP/C.AEP - customer-specific analogue start/end point
Settings for scaled display values.
The parameters are only displayed if [ScAL] is set to [cccc], [ccc.c], [cc.cc] or
[c.ccc].
C.ASP value: -746 ... 9745 corresponds to 4 mA.
C.AEP value: -366 ... 9366 corresponds to 20 mA.
If a scaling is set via [ScAL], the C.AEP value also has to be adapted accordingly:
With [ScAL] = [ccc.c] → C.AEP value x 10
With [ScAL] = [cc.cc] → C.AEP value x 100
With [ScAL] = [c.ccc] → C.AEP value x 1000
All displayed current values are interpolated based on a 2-point approximation ([SP1]+[rP1],
[FH1]+[FL1], [cFH]+[cFL], [Lo]+[Hi]).
IO-Link process data and parameters are not affected by the scaling.
