Endress+Hauser Liquiphant FTL31 IO-Link - Reading out and Writing Device Data (ISDU - Indexed Service Data Unit)

System integration Liquiphant FTL31 IO-Link
24 Endress+Hauser
The remaining 14 bits contain the value for the fork frequency [0 to 100 %]. A conversion is
not necessary.
Bit Process value Value range
15 OU2 0 = open
1 = closed
14 OU1 0 = open
1 = closed
0 to 13 Raw value, not coverage [0 to 100] Integer
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:
