Supervisory Control and Data Acquisition (SCADA) and Human Machine Interface (HMI) are closely related, and often referred to in the same context since they are both parts of a larger industrial control system, but they each offer different functionality and opportunities.

While HMIs are focused on visually conveying information to help the user supervise an industrial process, SCADA systems have a greater capacity for data collection and control system operation.https://913f8e1bb99a46543caf7d3d6e6abdab.safeframe.googlesyndication.com/safeframe/1-0-40/html/container.html

Unlike SCADA systems, HMIs do not collect and record information or connect to databases. Rather, HMI provides an effective communication tool that functions as part of, or alongside, a SCADA system.

SCADA – Olden Days versus Modern Days

In the olden days, we call the complete control system as SCADA. Meaning that it includes controllers, I/O modules, workstations, network communication, etc. But with the modernization of industrial automation, DCS and PLC systems are evolved and SCADA becomes part of these systems and now we use them for operator interface graphics. So, Do not confuse the definitions of SCADA between these decades.
