GB/T 16657.2-2008 Industrial communication networks—Fieldbus specifications—Part 2:Physical layer specification and service definition
Abstract
This section specifies the requirements for the components of the fieldbus, as well as the necessary media and network configuration requirements to ensure consistency in the following aspects: a) Data integrity before error checking at the data link layer; b) Interoperability between devices at the physical layer. The physical layer of the fieldbus complies with Layer 1 of the OSI 7-layer model defined in ISO/IEC 7498, with exceptions: for some bus types, the frame delimiter is at the physical layer, while for other types, the frame delimiter is at the data link layer.
