MTConnect is a manufacturing technical standard to retrieve process information from numerically controlled machine tools.
The initiative began as a result of lectures given by David Edstrom of Sun Microsystems and David Patterson, professor of Computer Science at the University of California, Berkeley (UCB) at the 2006 annual meeting of the Association for Manufacturing Technology (AMT). The two lectures promoted an open communication standard to enable Internet connectivity to manufacturing equipment. Initial development was carried out by a joint effort between the UCB Electrical Engineering and Computer Sciences (EECS) department, the UCB Mechanical Engineering (ME) department (both in the College of Engineering) and the Georgia Institute of Technology, using input from industry representatives. The resulting standard is available under royalty-free licensing terms.
MTConnect is a protocol designed for the exchange of data between shop floor equipment and software applications used for monitoring and data analysis. MTConnect is referred to as a read-only standard, meaning that it only defines the extraction (reading) of data from control devices, not the writing of data to a control device. Freely available, open standards are used for all aspects of MTConnect. Data from shop floor devices is presented in XML format, and is retrieved from information providers, called Agents, using (HTTP) as the underlying transport . MTConnect provides a RESTful interface, which means the interface is stateless. No session must be established to retrieve data from an MTConnect Agent, and no logon or logoff sequence is required (unless overlying security protocols are added which do). (LDAP) is recommended for discovery services.
