What is a Human Machine Interface?

Ally Controls LLC.

Human Machine Interface is the primary tools by operators to control and coordinate industrial processes. It is the interface between operators and the process. Operators control and coordinate manufacturing and industrial processes using the Human Machine Interface as it translates complex processes into actionable and usable information.

 HMI Systems

Modern HMI systems automatically directs the operator's attention to the problem. They ensure timely and easy identification of abnormal situations and also expose the relevant information at the right time, and to the appropriate people, to enable them make informed decisions.

HMI systems are used in industrial companies to display data visually, track production trends and time, monitor machine input and output, and also to oversee KPIs.

 Who uses HMI systems?

HMI is used by industrial organizations, as well aas other companies to optimize industrial processes by interacting with their machines. The industries who use HMI include manufacturing companies, energy and power stations, oil and gas, and many more.

The common roles that use HMI systems are engineers, operators and system integrators. HMI systems are an essential resource for these professionals and they use them to monitor processes, visualize data and diagnose problems.

SCADA Systems

Supervisory Control and Data Acquisition (SCADA system) always require a Human Machine Interface as it allows the operator to control the Remote Telemetry Units and the Intelligent Electronic Devices or connected equipment. HMI systems are critical components of a SCADA system. The HMI is used in reference to a single display panel with one or more screens to monitor a SCADA system.

HMI SCADA is a very important component of a remote controlling system. A SCADA system is usually large and can spread over a wide range of geographical areas. Sometimes, a SCADA system may also be small and limited to only one manufacturing facility.

A SCADA master, also popularly known as HMI SCADA, usually provides a number if extensions for a network alarm management. When an alarm goes off, an HMI SCADA will present the data to the human network operator in a usable form. After looking at the HMI systems, the operator can easily make informed decisions on the required response from few comprehensive windows. These comprehensive windows will allow the operator to have a comprehensive view of the SCADA system.

The HMI SCADA can provide comprehensive detail about a single alarm when a request is made by an operator through the Human Machine Interface. The HMI SCADA can also generate report logs for operators, summarizing trends in history to indicate possible problems.
