In smaller SCADA systems, the supervisory computer may be composed of a single PC, in which case the HMI is a part of this computer. In larger SCADA systems, the master station may include several HMIs hosted on client computers, multiple servers for data acquisition, distributed software applications, and disaster recovery sites.
Increasingly demanding industrial applications are part of the challenge. Also, SCADA concepts are technically simple but field applications that integrate several types of equipment can become complex to set up or troubleshoot due to variances in vendor implementations.
The VTScada SCADA platform is the company's main product. [1] Trihedral's has customers in fresh water and wastewater, subsea and terrestrial oil production, air traffic management monitoring systems, fire station and 911 emergency alerting systems, national broadcast networks, marine systems, manufacturing, and food & beverage industries.

It was soon adopted in a large number of other event-driven applications as varied as printing presses and water treatment plants. SCADA's history is rooted in distribution applications, such as power, natural gas, and water pipelines, where there is a need to gather remote data through potentially unreliable or intermittent low-bandwidth and ...
A remote terminal unit (RTU) is a microprocessor-controlled electronic device that interfaces objects in the physical world to a distributed control system or SCADA (supervisory control and data acquisition) system by transmitting telemetry data to a master system, and by using messages from the master supervisory system to control connected objects.

Inductive Automation introduced the server-centric architecture [2] for SCADA systems with FactorySQL and FactoryPMI in 2003. [3] The company is a pioneer of supporting interoperability standards among SCADA vendors, [4] and is a supporter of Open Source software and the OPC Foundation.
IntegraXor is a supervisory control and data acquisition (SCADA) and human-machine interface (HMI) software system developed by Ecava and first released in 2003. [ 1 ] [ 2 ] Function
The computer technology is also referred to as SCADA/EMS or EMS/SCADA. In these respects, the terminology EMS then excludes the monitoring and control functions, but more specifically refers to the collective suite of power network applications and to the generation control and scheduling applications.
