The data type value will be set automatically based upon the first valid I/O con-
nection established by the device.
If no established I/O connections exist, which include an attribute from this object,
then the
Data Type
attribute is settable provided that the object is in the
Idle State
.
Note: Using data type integer in combination with a pressure unit (mbar, Torr or
Pa) will obviously not produce reasonable values below 1.
The Data Unit is only settable in the IDLE state.
