A PROGRAMMABLE LOGIC CONTROLLER (PLC) is an industrial computer control system that continuously monitors the state of input devices and makes decisions based upon a custom program to control the state of output devices. That is, you can mix and match the types of Input and Output devices to best suit your application.
What are the three types of PLC?
PLC are divided into three types based on output namely Relay output, Transistor output, and Triac Output PLC.
What is a PLC for dummies?
PLC Ladder Logic Programmable Logic Controllers (PLCs) are small industrial computers with modular components designed to automate customized control processes. PLCs are often used in factories and industrial plants to control motors, pumps, lights, fans, circuit breakers and other machinery.
What is PLC programming used for?
A PLC is primarily used to control machinery. A program written for a PLC consists basically of instructions to turn on and off outputs based on input conditions and the internal program. In this respect, it is similar to how a standard computer application is used.
What is the main purpose of using a PLC?
PLCs communicate, monitor and control automated processes like assembly lines, machine functions, or robotic devices. A PLC's functions are divided into three main categories: inputs, outputs and the CPU. PLCs capture data from the plant floor by monitoring inputs that machines and devices are connected to.
What are the advantages of using PLC?
- Advanced technology.
- Less wiring.
- Compactness.
- Increased reliability.
- More flexibility.
- Lower cost.
- Communication capability.
- Faster response time.
What is PLC explain?
A PROGRAMMABLE LOGIC CONTROLLER (PLC) is an industrial computer control system that continuously monitors the state of input devices and makes decisions based upon a custom program to control the state of output devices.
What are the advantages of PLC control system?
Flexible in Nature: One model of PLC can be used for different operations as per requirement. Easy to install and troubleshooting: In hard wired relay based systems, installation time is more as compared to the PLC based control panels.
What is the advantage of having PLC in the industry?
A PLC is Easy to Use Functions are more reliable and consistent. In industry, the smallest timing error can cost thousands of dollars in wasted time and raw materials. This point alone makes PLCs the best option for industrial businesses. The other chief advantage of PLCs is their input/output capabilities.
What is PLC and its basics?
The basic elements of a PLC include input modules or points, a Central Processing Unit (CPU), output modules or points, and a programming device. The CPU evaluates the status of inputs, outputs, and other variables as it executes a stored program. The CPU then sends signals to update the status of outputs.
