Additional components are also available, and third-party applications can also interface with the platform.Evolving from Wonderware's earlier Factory suites, in 2006, the components of Factory Suite A2 were ArchestrA enabled and combined with Industrial Application Server to form the Wonderware System Platform. The goal was to provide a platform with common controls and development tools for integrating and managing legacy systems with the latest software.InTouchPart of the Wonderware platform, InTouch was the first, and is, the most widely used human machine interface (HMI) for plant visualization, automation and control. In the late 1980s, InTouch was Wonderware's first product (see InTouch).
