How does HMI / SCADA work?
HMI/SCADA collects data from RTUs (Remote Terminal Units), PLCs (Programmable Logic Controllers), and other control devices such as flow meters and temperature controllers. This data is presented to an operator using a Human Machine Interface (HMI). The HMI allows the operator to see what is going on in the plant in real time, including custom mimic displays, alarms, trends, etc., to make decisions to adjust any machine controls or settings.
HMI/SCADA can also be connected to other technologies, such as a data historian to allow for historical trending and other analysis. In fact, the foundation starts with capturing industrial data, combining it with other meaningful data sources for context and managing a historic record. It is data, turned into information, that provides the basis for meaningful outcomes.
Modern HMI/SCADA, including data historian and centralized visualization technologies, empower users to unlock the value of their data. The outcome is a high-productivity development and visualization environment that enables optimized plant operations, supported by faster development, a democratization of tools and capabilities throughout a plant, improved operational performance, lower costs, a changed mindset among employees, and a culture of continuous improvement.
The Industrial Landscape
The modern HMI/SCADA lets you guide newer operators through the right steps to take. And you can enable mobility and remote monitoring for greater efficiency. Welcome to the modern HMI/SCADA system—where machines, data, insights, and people are connected.
The advent of connectedness has brought about incredible opportunities for industry. Today, industrial machines and equipment are connected seamlessly to create and share a wealth of data.
Operators in manufacturing environments often have oversight over many pieces of equipment. HMI and SCADA solutions allow them to precisely monitor, control, and visualize every aspect of their operations in a centralized manner. With a quick glance, operators know what's important and the right actions to drive increased efficiency and reduced costs.
HMI/SCADA provides faster response for operators and faster development for engineers.
