What is a PLC programmable logic controller?
The PLC or Programmable Logic Controller is surely the cornerstone of the automation and process industry environment. Since its birth in the 1960s, as a replacement for electromechanical relay systems, it has been presented as an alternative for determining the operation of a machine control system or mechanical situations.
The origin of PLC comes from the concept of Programmable Logic Controller, which in English is Programmable Logic Controller. The PLC is an electrical circuit that automatically develops an established sequence, by means of wiring or programming. Such controllers are capable of automating a specific process, the operation of a specific machine or a complete production line.
As we have said, the conjunction of several programmable controllers make up sequential control systems. These systems will be implemented through programming in different languages and their function will be to organise specific orders within industrial automation. The most common programming is implemented by means of a contact diagram. The wide variety of options offered by a PLC automaton makes it possible for the technician to carry out modifications to the program without making important or costly changes to the wiring and its structure.
