Description of the variable AI_physical_unit_x (x = 1...4):
These variables contain the physical units and prefixes for the measuring channels used. The value of
the variables is determined by the sensor type specified in object “AI_sensor_type” (object 6110
h
).
The structure of the variable is defined in CiA 404. The coding of the physical units and prefixes is
done according to CiA303-2.
The structure of the variables is described on the following page.
