Device description
In order to integrate field devices into a digital communication system, the IO-Link system
needs a description of the device parameters, such as output data, input data, data format,
data volume and supported transmission rate.
The data are included in the device description (IODD) that are provided to the IO-Link
master during commissioning of the communication system.
The IODD can be downloaded as follows:

DC 24 V (nominal voltage: DC 18 to 30 V)
• The power unit must be safety-approved (e.g. PELV, SELV).
• The maximum short-circuit current must not exceed 50 A.
2.5 W (no outputs)
Order code for "Output, input"
Option FA: IO-Link, 1 pulse/frequency/switch output
1) If pulse/frequency/switch output is used
Switch-on current
Option FA: IO-Link, 1 pulse/frequency/switch output
Max. 400 mA (< 20 ms)
• Totalizers stop at the last value measured.
• Configuration is retained in the device memory.
• Error messages (incl. total operated hours) are stored.
The device is operational 3 seconds after the supply voltage is applied
Input cyclic process data
