Basic PLC Components and How They Work Programmable Logic Controllers or PLC’s are solid-state devices designed to perform logical decision making for control applications in the industrial environment. They were immediately accepted in the automotive industry and are found in countless applications in many industries. Programmable Logic Controllers perform functions that formerly required relays, solid-state electronics, or mini computers. They are a lightweight device that s rugged and operates without fans, air conditioning or electrical filtering. Programmable Logic Controllers are simple to program. They use a relay ladder language that s very similar to magnetic relay circuitry. Engineers, technicians, and electricians can learn to program the Programmable Logic Controllers without extensive training or experience. There are numerous advantages in using Programmable Logic Controllers versus a relay or solid-state electronics. In a Programmable Logic Controller, changes ca Less
