Mr Ouyang Jinsong, Director of Standardisation, Department of Instrumentation Technology and Economy Institute, People's Republic of China and General Secretary of the national standardisation 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 standardisation authorities have been working closely with Schneider Electric as they develop and propogate 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 standardisation decision.".
