MTConnect is a manufacturing industry standard to facilitate the organized retrieval of process information from numerically controlled machine tools. The initiative began as a result of lectures given by David Edstrom of Sun Microsystems and Dr. 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) membership.〔(【引用サイトリンク】title=Sun Microsystems Champions Open Standards to Usher in a New Era in Manufacturing )〕 The two lectures, “How the Internet’s Participation Age Will Drive Dramatic Changes in the Machine Tool Industry” & “Creating A Thriving American Manufacturing Base In The 21st Century America” described the need for an open communication standard to enable Internet connectivity to manufacturing equipment. Initial development of the standard was carried out by a joint effort between the UCB Electrical Engineering & Computer Sciences (EECS) department, the UCB Mechanical Engineering (ME) department (both in the College of Engineering) and the Georgia Institute of Technology,〔(【引用サイトリンク】title=Article from Production Machining: Computer Standard To Streamline Shops )〕 using input from industry representatives. The resulting standard is available under royalty-free licensing terms.〔(【引用サイトリンク】title= Article from American Machinist: MTConnect in your Future )〕 ==Description== MTConnect is a lightweight, open, and extensible protocol designed for the exchange of data between shop floor equipment and software applications used for monitoring and data analysis. In its current form, 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 Hypertext Transfer Protocol (HTTP) as the underlying transport protocol. 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). Lightweight Directory Access Protocol (LDAP) is recommended for discovery services. Version 1.0 was released in December 2008.〔(【引用サイトリンク】title= MTConnect Newsletter January 20, 2009 )〕 The first public demonstration of MTConnect occurred at the International Manufacturing Technology Show (IMTS) held in Chicago, Illinois September 2008.〔(【引用サイトリンク】title=ThomasNet: IMTS 2008: The "Rosetta Stone" of Interoperability and More )〕 There, 25 industrial equipment manufacturers networked their machinery control systems, providing process information that could be retrieved from any web-enabled client connected to the network.〔(【引用サイトリンク】title= MTConnect Newsletter October 7, 2008 )〕 Subsequent demonstrations occurred at EMO (The European International Machine Tool Show) in Milan, Italy in October 2009,〔(【引用サイトリンク】title= A View From EMO Milan )〕 and the 2010 IMTS in Chicago.〔(【引用サイトリンク】title=MTConnect at the Show )〕 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「MTConnect」の詳細全文を読む スポンサード リンク
