Automation describes a wide range of technologies that reduce human interference in
processes. It is the process of making things automatic. Automation uses computer-aided
technology and they make use of sensors, feedback control loops and automatic actuating
devices.
In automation, advanced controllers like Programmable Logic Controller(PLCs) are
developed for various operations.

AU TO M AT I O N S Y S T E M :
Automation system uses 3 components-
Sensors: The role of a sensor in an automation system is to detect and measure physical quantities and
converts it into data that can be interpreted by a machine. Sensors used in automation system are- temperature
sensor, proximity sensor, pressure sensor, position sensor etc.
Feedback control loops: Fundamentally, there are two types of control loops- open-loop control, and closed-loop
feedback control.
In open-loop control, the control action is independent of the process output.
In closed-loop control, the control action is dependent on the process output. It has a feedback loop that ensures
the controller exerts a control action to give a process output equal to the Reference input or set point.
Actuating devices: An actuator is a device that moves or controls some mechanism. An actuator turns a
control signal into mechanical action such as an electric motor.

Industrial Automation is the process of making industrial processes more flexible and simpler. It
involves usage of devices like PLCs, various sensors and actuators, communication buses, HMI
systems etc.
Industrial Automation Systems are usually categorized into four types.
• Fixed Automation System.
• Programmable Automation System.
• Flexible Automation System.
• Integrated Automation System.

8. H O M E A U T O M AT I O N :
A home automation system will monitor and control home attributes such as lighting, climate,
entertainment systems, and appliances. It may also include home security such as access control and
alarm systems. When connected with the Internet, home devices are an important constituent of
the Internet of Things(IOT).
The user interface for control of the system uses tablet or desktop computers or a mobile phone
application.

PLC stands for Programmable Logic Controllers. They are used to control automated
systems in industries. They are one of the most advanced and simplest form of control
systems which are now replacing hard-wired relays.

SCADA stands for Supervisory Control And Data Acquisition. It is a system of software and
hardware elements that allows industry to-
• Control industrial processes locally or at remote locations
• Monitor, gather, and process real-time data
• Directly interact with devices such as sensors, valves, pump and motor through HMI(Human Machine Interface)

21. H M I :
HMI stands for Human Machine Interface. It is defined as a feature or component of a
certain device or software application that enables humans to engage and interact with
machines. Some examples of common Human Machine Interface devices that we
encounter in our daily lives include touchscreens and keyboards.
It is sometimes referred to as Man-Machine Interface (MMI).
In industrial settings, HMIs can be used to:
• Visually display data
• Track production time, trends, and tags
• Monitor machine inputs and outputs
