Modbus conformance test lab opens in China


North Grafton, MAModbus-IDA and the Instrumentation Technology & Economy Institute (ITEI) announced the opening of ITEI’s Modbus Conformance Test Laboratory in Beijing, China. As part of its expanding conformance test program, Modbus-IDA is contracting with organizations around the world to offer conformance testing and certification of Modbus devices. Ouyang Jinsong, director of standardization, ITEI, and general secretary on industrial process measurement and control, will introduce the laboratory and its capabilities during a four-city tour of China this month.

The lab tests and certifies devices as conforming to Modbus TCP/IP specification of Modbus over serial line. Planning for the lab begin in Jan. 2005 and was completed with the help of Schneider Electric . Conformance and interoperability tests are performed with equipment donated by Schneider Electric. Devices tested will be listed on the Modbus-IDA Website.

The new laboratory marks the importance of Modbus around the world and its importance in the growing Chinese manufacturing market, noted Modbus-IDA president Ken Crater. “Modbus-IDA is delighted to be working with the ITEI to make conformance testing easily available for device suppliers in Asia,” he said.
