Conductivity: 0 to 110
000 µS/cm, resolution 0.1 µS/cm
Buildup: 0 to 10 mm, resolution 0.1 mm
UInt24: offset = 0, gradient = 0.1
UInt8: offset = 0, gradient = 0.1
In addition, the value for buildup and conductivity can be read via ISDU (hex) 0x0028
– acyclic service.
8.2
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:
