AS 3000 IO-Link
One decimal place is used both for the saturation degree and for the temperature.
2 further bits function as switching bits ("BDC" = "Binary digital channel"), which can be
parameterised just
Parameterisation).
The process bits are arranged in one or 2 data words in accordance with Table 1. In order
to receive the physical measured value for further processing in the controller, a bit shift
operation must first be carried out for each data word (shift right 2).
