PD IEC PAS 63256 defines the broadband fieldbus specification AUTBUS. AUTBUS implements real-time, high reliability and deterministic transmission and application for both industrial fieldbus data and ISO/IEC/IEEE 8802-3 Ethernet data by shared medium bus.
PD IEC PAS 63256 explains the structure and content of AUTBUS and describes the definition and specification of Physical Layer (PhL) protocol / service, Data-link Layer (DLL) protocol / service and Application Layer (AL) protocol / service of AUTBUS.
AUTBUS data coding specifies the machine independent syntax for the data conveyed by each layer services. AUTBUS supports the definition and transmission of basic and complex data types.
PD IEC PAS 63256 on broadband fieldbus specification AUTBUS is useful for:
AUTBUS is an industrial fieldbus with two-wire medium and 100 mbps bandwidth, which is used for process control and distributed control applications and is compatible with IPv4 and IPv6. AUTBUS is designed to combine the advantages of conventional fieldbus systems and real-time industrial Ethernet. PD IEC PAS 63256 describes AUTBUS protocol stack architecture which follows open system interconnection (OSI) reference model.
In PD IEC PAS 63256, the AUTBUS provides you with fixed-bandwidth data service and variable bandwidth data service for periodic real-time process data, burst real-time control, alarm data and non-real-time data through pre-configuration or dynamic application of physical communication resource.
PD IEC PAS 63256 supports network slicing technology and it implements the transmission and application of the existing fieldbus based on the AUTBUS network. AUTBUS adopts Orthogonal Frequency Division Multiplexing (OFDM) technology, and has feature. It is a deterministic fieldbus communication network based on high-precision clock synchronization.
