    data integrity before data-link layer error checking;<\/p>\n<\/li>\n

  2. \n

    interoperability between devices at the physical layer.<\/p>\n<\/li>\n<\/ol>\n

    The fieldbus physical layer conforms to layer 1 of the OSI 7-layer model as defined by ISO 7498 with the exception that, for some types, frame delimiters are in the physical layer while for other types they are in the data-link layer.<\/p>\n
