Fieldbus - Features

Features

Different fieldbuses offer different sets of features and performance. It is difficult to make a general comparison of fieldbus performance because of fundamental differences in data transfer methodology. In the comparison table below it is simply noted if the fieldbus in question typically supports data update cycles of 1 millisecond or faster.

Famous quotes containing the word features:

    ““It looks as if
    Some pallid thing had squashed its features flat
    And its eyes shut with overeagerness
    To see what people found so interesting
    In one another, and had gone to sleep
    Of its own stupid lack of understanding,
    Or broken its white neck of mushroom stuff
    Short off, and died against the windowpane.””
    —Robert Frost (1874–1963)

    “The features of our face are hardly more than gestures which force of habit made permanent. Nature, like the destruction of Pompeii, like the metamorphosis of a nymph into a tree, has arrested us in an accustomed movement.”
    —Marcel Proust (1871–1922)

    “However much we may differ in the choice of the measures which should guide the administration of the government, there can be but little doubt in the minds of those who are really friendly to the republican features of our system that one of its most important securities consists in the separation of the legislative and executive powers at the same time that each is acknowledged to be supreme, in the will of the people constitutionally expressed.”
    —Andrew Jackson (1767–1845)
