Improvement in the programmable logic controller enables a set of circuits eletru00c8nicos perform different functions and the change process of caracteru00ecsticas fu00ecsicas entries and exits of programmable logic controller, the present invention relates to architecture AP Licu00e1vel in programmable logic controller that uses electronic circuits with programmable logic.Allowing the arrangement of circuit configuration by means of a file programming of entries and exits, loaded by the user. The invention also relates to a process of change of physical characteristics of the inputs and outputs of the programmable logic controller.The architecture of the invention allows the hardware of a programmable controller (PC) can be reconfigured, performing different functions of control, regardless of the application software.The changes of the physical behaviour of the hardware are configured by the load on the controller of a dedicated file (FPGA), specific for each function to be executed, performed by the user of the CP, a new process for applications with FPGA.The reprogramming of hardware occurs so that this pattern is decoded and processed by the programmable integrated circuit (FPGA) without requiring modification of actual components that make up the hardware. The system presented differs from other solutions available for allowing the use of only one type of CP for the implementation of several functions of the hardware.Conventional solutions, until then, require, for each function, it is necessary to have different architectures of electronic circuits, giving rise to different models of programmable controllers.
