In 1987, Trihedral released ‘WEB’, a DOS-based HMI product that can still be found operating in the field today. In 1995, the name became Visual Tag System (VTS) to reflect the graphic capabilities made possible by the Windows Operating System. In 2001, Trihedral developed VTScada, a set of dedicated telemetry features included with every VTS license. In version 11, the product has simply become VTScada and sports the new logo found at the top of this page.
