Also question is, What is the purpose of an RTU?

An RTU is an electronic device utilizing a microprocessor, which links objects in the physical world with an automation system. This is accomplished by transmitting telemetry data to the system and/or changing the physical state of connected objects based on control messages received from the automation system.

Moreover, Where are RTUs used?. Remote terminal units (RTUs) are used in commercial and industrial systems throughout the world. Typical applications include the supervisory control and data acquisition (SCADA) systems used by electric, water and wastewater utilities.

Keeping this in consideration, What is the function of RTU in Scada?

An RTU (remote terminal unit) interfaces the sensors to the SCADA Master Station or Communications Network. RTUs provide telemetry information and some local control facilities. They differ to Programmable Logic Controllers (PLCs). Both are microprocessor controlled electronic devices.

What are the benefits of RTU over PLCs?

RTUs are considered more suitable for wider geographical telemetry, the reason being that RTUs use wireless communication; PLCs are more suitable for local control, for example, for assembly lines in factories, light fixtures, amusement rides, etc.
