VTScada.
VTScada is both a Human Machine Interface (HMI), and a Supervisory Control and Data Acquisition (SCADA) software package. Functionally, VTScada includes real-time monitoring and control, telemetry, alarm and events management, alarm notification, data acquisition, reporting, trending, mapping, application version control, Internet and mobile access.
VTScada communicates with Programmable Logic Controllers (PLCs), Remote Terminal Units (RTUs), pump controllers and other devices using radio, LAN, WAN, cellular, or phone lines. This information is logged and displayed to users on a computer screen via trend graphs, reports, or graphical display pages. The software can also send control signals back to the devices to control the process.
The VTScada software is used by nearly 900 municipalities across the United States, and thousands of industrial customers globally. Notable uses of the software include:
History.
Glenn Wadden founded Trihedral in 1986. In 1988, the company released “WEB”; one of the first PC-based SCADA packages that ran on the DOS platform. Trihedral briefly trademarked the term "WEB" in 1990, before the Internet's widespread proliferation. In 1998, Trihedral Engineering Limited opened a 100% wholly owned subsidiary, Trihedral UK, in Aberdeen, Scotland. In 1997, WEB became Visual Tag System (VTS) and was updated to run on the Windows operating system. By 2007, Trihedral had developed VTScada, an integrated toolset of telemetry features designed for the water and wastewater industry. The same year, Trihedral, Inc., opened in Orlando, Florida.
