Example 2:
The analog mode is set to 4-20 mA
The resolution is 12 bit.
The process data is left aligned.
The digitalized value read over IO-Link is ABC0
hex
In case of 4-20 mA, the analog input current range is between 3.8 mA and 20.5 mA. The
digitalized value is read over IO-Link as a 16 bit value, but the resolution is 12 bit and it is
left aligned, so the 12 bit digitalized data is ABC
hex
= 2748.
