10. Process Data
The process data exchanged by the product with the IO-Link master using IO-Link cyclic communication is as
follows.
UR-DS4AD
IO-Link process data is transferred in big endian format. The table below is also in big endian format.
The IO-Link master UR series from OPTEX FA transfers IO-Link process data converted into little endian format
to the host network by default, so please refer to the table below for "Word assignment" (page 24).

*1 If the analog input value drops below the lower limit in the 1 to 5 V input or 4 to 20 mA input, the process input data will be 32768
(0x8000).
*2 When index number 74 (“Type of analog input”) of the service data is “0”, this designation by process output data is valid. Note that
the process input data is fixed at 0 to 10 V input for “1”, -10 to 10 V input for “2”, 0 to 5 V input for “3”, 1 to 5 V input for “4”, 0 to 20
mA input for “5”, and 4 to 20 mA input for “6”.
