scope:
This part of IEC 1158 specifies the requirements for Fieldbus component parts. It also specifies the media and network configuration requirements necessary to ensure agreed levels of: a) data integrity before Data Link Layer error checking; b) interoperability between devices at the Physical Layer. The Fieldbus Physical Layer conforms to layer 1 of the OSI 7-layer model as defined by ISO 7498 with the exception that frame delimiters are in the Physical Layer.
