Reading Out And Writing Device Data (Isdu - Indexed Service Data Unit) - Endress+Hauser Liquiphant FTL31 IO-Link Operating Instructions Manual

System integration
The remaining 14 bits contain the value for the fork frequency [0 to 100 %]. A conversion is
not necessary.

0 to 13 Raw value, not coverage [0 to 100]
The fork frequency is provided by the device as int13. The decimal separator must then still be
determined using a gradient.
9.2 Reading out and writing device data (ISDU – Indexed Service
Data Unit)
Device data are always exchanged acyclically and at the request of the IO-Link master. Using
the device data, the following parameter values or device statuses can be read out:
