NORTH GRAFTON, Mass. - Modbus-IDA and the Instrumentation Technology & Economy Institute (ITEI) announced the opening of ITEI's Modbus Conformance Test Laboratory in Beijing. As part of its expanding conformance test program, Modbus-IDA is contracting with organizations in locations around the world to offer conformance testing and certification of Modbus devices. Planning for the ITEI lab started in January 2005. With the help of Schneider Electric engineers, the lab is open and available to test and certify devices as conforming to Modbus TCP/IP specification or Modbus over Serial Line.

Conformance and interoperability tests are performed with equipment donated by Schneider Electric. Tested devices will be listed on, which features a growing database of Modbus devices for users to search and identify the proper devices for their applications. "The launch of this new laboratory is a marker of the ubiquity of Modbus around the world and its importance in the growing Chinese manufacturing market," said Ken Crater, president of Modbus-IDA. "Modbus-IDA is delighted to be working with the ITEI to make conformance testing easily available for device suppliers in Asia."
