Main difference between SCADA and HMI

SCADA and HMI are forms of technology that are heavily reliant on each other. However, both of them are still different in certain regards.

SCADA stands for Supervisory Control And Data Acquisition, and revolves around the gathering and analysis of the data generated in various business processes.

The main aim of this methodology is to streamline business functionality by figuring out the best way to optimise business processes with relative ease.

Meanwhile, HMI stands for Human-Machine Interface, and basically refers to the transparency and convenience of providing information by translating complex machine language into a format that can be understood by the masses.

This technology is very important for businesses, since the reliance on technology is higher than ever before.

Therefore, it’s important to ensure that employees are able to understand the machines they work with, and report or take care of any discrepancies that might arise during its daily workings.

The main difference between SCADA and HMI arises from their scope. While HMI is a part of SCADA, SCADA is certainly not a part of HMI.

We say this because SCADA covers a wide range of applications and use-cases, while HMI is only used for one thing – facilitating transparency of information between humans and machines.
