Control and Field Level Devices
This lecture covers the fundamentals of control and field level devices in industrial automation. It starts with an introduction to Programmable Logic Controllers (PLCs), explaining their components and functions. The lecture then delves into PLC programming, different types of PLCs (compact, modular, soft), and their characteristics. It also discusses the importance of 24V/48V supply in industrial settings. The location of PLCs in automation architecture, programming methods, and various control mechanisms like two-point controllers, PID controllers, and nested controllers are explained. The lecture concludes with topics on plant modeling, control loops, and advanced control strategies.
