Designed with mission critical in mind.

A wide variety of industries around the world use VTScada for mission-critical applications of every size. Built on one of the world’s first reactive programming languages. This event-driven software methodology is now being utilized in large-scale platforms such as Google and Facebook. VTScada pioneered high uptime features that are found in few, if any, other control system software.

More than HMI and SCADA Software

VTScada also natively includes components not commonly found in HMI or SCADA software platforms such as polling management, historian, trends viewer, report generation, application version control, alarm notification, and system backup. You install everything at once in just a few minutes.

Instantly Intuitive HMI SCADA Software

Creating great SCADA software applications should be easy. VTSCada is powerful enough to make you productive in an hour, with instantly intuitive tools and a unique architecture that integrates all core SCADA software components in a single, easy-to-use package. Download the VTScada 90-day trail and follow along with our easy VTScada video tutorials to see for yourself why we call VTScada ‘instantly intuitive’.

What Is HMI software?

Human machine interface software allows industrial end users to monitor and control equipment using a computer. This can include operating pumps and motors or displaying temperatures and fluid levels on a screen.

What is SCADA Software?

Supervisory control and data acquisition (SCADA) systems are comprised of HMI software (such as VTScada) that uses a network to communicate with distributed remote telemetry units (RTUs) and programmable logic controllers (PLCs) to control remote hardware and retrieve logged process information. For example, municipal utilities can use radios to centrally monitor and control water distribution and wastewater collection sites spread over a wide geographical area or an Ethernet network to oversee multiple treatment plants.

Great Software Means Great Support 

Our in-house developers are constantly rolling out new features while our famous technical support team provides the most personal and accessible technical support in the industry. Don’t take our word for it. Ask our customers.

Powerful Enough to Scale Indefinitely

Built for applications monitoring hundreds to millions of I/O on a single server, VTScada’s speed, stability, scalability, and support have made it a trusted SCADA alternative for 35 years.

Non-proprietary HMI SCADA Software

VTScada’s hardware independence and open connectivity support all major PLCs or RTUs and provide an advancement over polling with Master PLCs.

Integrated is Better

A single file installs all components while VTScada’s unique server architecture offers no-compromise load-balancing and hot-backup failover using fewer computers. Integrated real-time application version control permits auditing and instant on-line recovery from unexpected effects of user configuration.

Start Small. Think Big.

This cost-effective and easily-integrated SCADA solution includes everything you need for a fully functional monitoring and control system. All standard and optional components are integrated into the product and can be unlocked by simply updating an installation key. Easily expand your system from a simple OEM machine interface or standalone workstations to a large, distributed client/server system.


In 1988, 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 VTScada license. In version 11, the product simply became known as VTScada and sported the new logo found at the top of this page.
