Resumen
This research presents the design of a soft-plc based on a reduced plate computer (SBC) raspberry. In its development the project is described with the fulfillment of the characteristics and qualities of hardware and software of a PLC device and as it becomes a fully operational platform in an academic and industrial environment, where a firmware is used Subscribed to the CODESYS programming environment of the German software company 3s-Smart, along with a PSoC 5LP-based peripheral board. As a result, the implementation study allowed to consolidate a design with the regulations on land isolation, among other standards or standards studied and implemented in the final design that contains the following specifications: four inputs and Analog outputs Standard Industrial 4-20ma, eight digital I/O, driver for ModBus RTU/TCP communication.
