Introduction
CNC system NCUC-Bus Fieldbus (NCUnionofChinaFieldBus, NC Union bus, hereinafter referred to as
NCUC-Bus) is a communication protocol specification for CNC machine tools and industrial automation and control processes developed.
This section GB/T 29001 General CNC system is NCUC-Bus fieldbus, GB/T 29001 defines the "three-tier" now
Fieldbus reference model reference model will standardize the interconnection region is subdivided into a series of levels of specification, each with range management. This portion
Each part of the standard GB/T 29001 reference model defined by relevant, is part of the structure and composition of each general description.
This section is a combination of structural and functional requirements in recent years, scientific and technological development and the development of CNC machine tools.
