Controlador lógico programável CLP

Abstract

This study aims to address the theme of "Programmable Logic Controllers (PLC). Thus, initially sought to include the principle of automation. Then it was the drivers themselves, their short history and evolution, the block components of the system, working principle, the physical structure of the CLP and its basic applications. PLC's technology has been addressed in its details of hardware, CPU module, system memory, power supplies, battery, input and output modules for analog and digital and special modules. Application of PLC for naval use was included in the main types of applications in deck machinery, walkway systems and universal-multiplexed command, the rudder control system and the supervisor of the telegraph machine. The study concludes that can be applied in the preventive and corrective maintenance, and technical assistance in repair of electronic controls and systems interfaces and electro hydraulic servo. Use has also important with respect to machines, the automation, supervision and regulations of system security, instrumentation, controls pressure and exciter with remote information and communication intercom. Moreover, it can act in the central government in control and alarm safety to navigation, and signaling systems interfaces with the square of machinery.
