There are a number of new inventions which are made in the field of automation. But new inventions are always coming. PLCs were quite popular till a few years ago. But now they are replaced by other new modes automation.

The upgrade automation systems

The field of automation in the industrial sector is not small. From time to time new automation methods and new devices for the purpose of automation has come to the market, eradicating those, which are old-fashioned. Once there was a time, when you logic controllers were used extensively in the industrial sector, but they are no longer used extensively in big industries. They’re not still out of the picture, as they are used in small scale industries, who do not have a lot of money to invest on complex automation systems.

The news systems

Programmable Logic Controllers or PLC controllers are now replaced by SCADA based and HMI systems, which gives better efficiency and better control methods compared to that of PLCs. SCADA is the abbreviation of the term Supervisory Control And Data Acquisition. HMI is also a short-term, which is the abbreviation of Human machine interfaces. The device of such devices with PLCs is that, there is no smart human interfacing in PLCs compared to those which are available in the system as mentioned above. The cost of setting up a SCADA and HMI based systems is higher compared to that of the PLC based systems.

A recent calculation

In a statistical calculation made by an authority in the US, it has been found out that there is a 30% reduction in the use of programmable logic controllers in high-end industries in the last 4 years. It is expected that within the next 2 to 3 years, the high-end industries will completely eradicate PLCs from their systems by replacing it with newer systems.
