There are many software packages built in direct support for SCADA HMI applications. They are both licensed as well as free depending on the back-end support offered. The thing that makes them different is the support for a wide range of drivers, an extensive list of communication protocols like Modbus TCP and RTU, Siemens, OPC and much more all integrated into s single piece of software. This scale of flexibility and operation usage is unavailable in free versions that are built to be open-sourced without backing from large business organizations. These also come with a plethora of acquisition devices that offer serial converters, loggers for small, medium to large-scale operations. They can be installed in small factories to even large industries.

In order to make them more efficient, software packages running SCADA have inbuilt support for Symbol Factory 2.5 and similar versions that offer thousands of versions of symbols for electrical and electronic components modeled using mathematical models for the same. Thus, real-world systems can be modeled using these software packages and any developer can build monitoring tools using such a package. There are many such packages today. The main aim of this software is allowing data acquisition from those thousands of devices, collecting sensor data from measuring instruments like temperature, thermisters, electrical units like voltage and current and so on. These variables help monitor a lot of the processes. There are also other animated objects like potentiometers, LED displays, indicators, buttons, and switches that help simulate the actual environment in the industry.
