The default values unit
SensorType
_x (x = 1 - 4) depend on the sensor-type set.: With the default-setting of object 6110
h
=10 000 (2710
h
= resistance measurement) it would be 2 621 440
d
= resistance in Ohm.
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 DS 404. The coding of the physical units and prefixes
is done according to CiA303-2 [5].
The structure is described on the following page.
