UR-DS4DA
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 25).

*1 If index number 74 (“output range selection”) of the service data is “0”, specification using this process output data is enabled.
If it is “1”, “2”, “3” or “4”, output will be fixed to 0 to 10 V, -10 to 10 V, 0 to 5 V and 0 to 20 mA, respectively.
Word assignment
Example: When using the IO-Link master UR series of OPTEX FA (default setting: little endian)
By default, the data is converted to little endian format and transferred to the field network, so refer to the table
below.
