Foreword
GB/T 19760 "CC-Link communication network control and specification" is currently divided into four parts.
--- The first part 1. CC-Link protocol specification;
Part --- Article 2. CC-Link realization;
Part --- Section 3. CC-Link profiles;
--- Part 4. CC-Link/LT protocol specification.
This section GB/T 19760 Part 1.
The partial modification of the use of CC-Link Association standards BAP-05026-L "CC-Link Specification Overview and protocol specification", its technical content
Consistent with BAP-05026-L.
GB/T 19760-2008 Compared with GB /Z19760-2005, on the technical contents have not been adjusted, the structure is divided into 4 portions
Points to meet the needs of different users used alone. This Part replaces GB /Z19760-2005 "control and communication bus CC-Link specifications"
The "CC-Link protocol specifications" section.
For ease of use, this section made the following editorial changes.
a) According to China's actual use, in accordance with the provisions of GB/T 1.1-2000, the original text was revised editorial;
b) the original text references to other international standards have been adopted as identical or modified our standard, this part of the standard number used in place of
Corresponding international standard number, and the rest not equal or modify adopted as our standard of advanced international standards in this section are
Direct reference;
c) The description of individual editorial errors were corrected.
This part is proposed by China Machinery Industry Federation.
This part of the measurement and control of Standardization Technical Committee of the Fourth Technical Committee under the jurisdiction of the national industrial processes.
