Operation ILR2250-100-IO
7.1
Getting Ready for Operation
Install the ILR2250 sensor as per the installation instructions,
Connect the system to the downstream display or monitoring units and to the voltage supply.
The sensor may only be connected to peripherals when it does not carry power, that is, only when the
supply voltage has been switched off.
The measurement laser starts when the supply voltage is applied if an active measurement (see
LASER MEASURE ON
)
has previously been saved in the sensor.
The sensor is ready to use after approx. 2 s, digital accuracy is immediate.
i
The sensor can be put in an autostart state. To do this, all desired parameters must be set and saved on the sensor.
If the sensor is then switched off during an active measurement, it immediately resumes the saved measurement
task once the power supply is connected again.
If the
POWER
LED is off, no power is being supplied.
7.2
Operation using IO-Link
The sensor exchanges process data and parameters via IO-Link. For this purpose, connect the sensor with a suitable
IO-Link master.

Process Data
The factory settings ensure that the process data telegram of the sensor receives the measured distance value. The dis-
tance value is output in tenths of a millimeter (27 bit signed integer). In addition, the logical state of the three switching
outputs is transmitted by the last three bits.
Bit 0 – bit 26
Measurement value

ErrorOut3 (switching output 3)
Bit 30
ErrorOut2 (switching output 2)

7.4
Device Data
The device data include
-
parameters,
-
identification data and
-
diagnosis data.
This information can be transmitted to or from the sensor in parallel with the process data. For this purpose, the IO-Link
master requires a sensor-specific device description file (IODD).
The current device description file is available at:
