Week 1: Introduction to PLCs

Flashcards covering key concepts from the lecture on PLCs and industrial automation.

Automation

The use of technology to perform tasks with minimal human intervention.

PLC

Programmable Logic Controller, an industrial digital computer used for automation of electromechanical processes.

Fixed Automation

Automation systems designed for high-volume production using dedicated equipment.

Programmable Automation

Automation suitable for batch production that can be reprogrammed for different tasks.

Flexible Automation

Automation that allows for adaptable production processes, changing product configurations quickly.

CPU

Central Processing Unit, the brain of the PLC that executes control instructions.

Input Module

The component that interfaces with input devices like sensors and switches.

Output Module

The component that interfaces with output devices such as motors and valves.

Communication Module

Enables PLCs to communicate with other PLCs or control systems.

Advantages of PLCs

Flexibility in programming, compact design, durability in harsh conditions.

Disadvantages of PLCs

Complex initial setup and higher costs compared to traditional relay systems.

IoT Integration

Connecting PLCs to the internet for enhanced remote monitoring and control.

Impact of PLCs

Simplified control system design, reduced downtime, and enhanced automation flexibility.

History of PLCs

Developed in the late 1960s to replace relay-based systems; includes multiple generations of evolution.

Applications of PLCs

Used in manufacturing, process control, building automation, and transport systems.
