12 - What are the distinguishing features of a "true" Fieldbus, delivering the original promise?

The main characteristics of Fieldbus are:

Completely digital replacement of 4-20 mA;
Control, alarm, computation and other functions distributed to devices in the field;
Multi-vendor interoperable through open specification;
Specifically designed for process control;
DCS/smart-transmitter and other protocols calling themselves Fieldbus do not show these characteristics;
