North Grafton, MA (January 11, 2005) — In a striking affirmation of the ubiquitous Modbus protocol, the Standardization Administration of China(SAC) has formally launched the following three standards for industrial automation in the People’s Republic of China:
GB/Z 19582.2-2004 Modbus Industrial Automation Network Specification Part 2 Modbus Protocol Implementation Guide over Serial Link
GB/Z 19582.3-2004 Modbus Industrial Automation Network Specification Part 3 Modbus Protocol Implementation Guide over TCP/IPMr. Ouyang Jinsong, Director of Standardization, Department of Instrumentation Technology & Economy Institute, People’s Republic of China and General Secretary of the National Standardization Technical Committee on Industrial Process Measurement and Control confirmed the standards were effective October 26, 2004.The news was welcomed by Modbus-IDA, the international organization for suppliers, implementers and users of Modbus and its companion protocols. The Chinese standardization authorities have been working closely with Schneider Electric as they develop and propagate the use of standards in their industrial infrastructure. In conjunction with launching the Modbus standard, a conformance test laboratory is anticipated to open in China within the next few months.Ken Crater, president of Modbus-IDA, noted, “It makes sense that the Chinese industrial market adopt Modbus as its fieldbus standard. Simplicity and ease of integration make it a natural choice. The fact that it is already widely used in China was also an important factor in the standardization decision.”About Modbus-IDA:Modbus-IDA is headquartered at 37 Wheeler Rd., North Grafton, Massachusetts, USA.
