Hands-On Industrial Internet of Things

Level 2 – RTU, embedded controllers, CNCs, PLCs, and DCSes

The level 2 includes all devices that interact directly with the sensors and the actuators implementing so the control and the safe functionalities both for a single equipment and for working cells and entire production lines; they are the followings:

• Remote terminal unit (RTU) is an electronic device that is controlled by a microprocessor. It acts as an interface for sensors, actuators, and intelligent devices by transmitting data and receiving command messages from a master system. It is basically used to centralize the input and output to and from the sensors and actuators by reducing the complexity of their cabling and wiring.
• Embedded controller is generally a single chip or ...
