All Data Type attributes use the enumerated values integer or float
(
→ Appendix A).
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.
