Logical controllers' programming 2 - Programming 2 -Introduction to the programming üTo program means to order with clarity a group of instructions that step by step they execute operations. . üThat group will have to be a send to the controller in a language structured by form to be interpreted by the Central Unit without ambiguities. üEverything it should pass as if we taught to a human being the acting of the same tasks.
