3 Intended use
The unit is used to detect signals from a connected sensor or another device with an analogue output
(0...10 V). It has two analogue voltage inputs.
DP1222
IN2 (analogue)
IN1 (analogue)
IO-Link C/Q
Fig.1: Inputs/outputs of the unit
The unit operates as an "analogue/IO-Link converter".
A maximum of 11 V may be applied to each input. Otherwise, the accuracy of the respective
other channel will be negatively affected.
If the LED IN1 / IN2 flashes and the IO-Link event "Process value above valid range" (0x8C10)
is present, the accuracy of the other channel can no longer be guaranteed.
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
The unit provides the IO-Link process data according to the analogue input signals.
The unit is designed for half-duplex communication. So the following options are possible:
• Remote display: reading and displaying the current voltage value
• Remote parameter setting: reading and changing the current parameter setting
• IO-Link parameter setting: IO Device Description (IODD) (Ò/7)

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:
