Al ejecutar el bucle con la suficiente rapidez, el efecto sigue pareciendo una ejecuci\u00f3n simult\u00e1nea e inmediata dentro de la tolerancia temporal requerida.<\/p>\n<p>Durante la programaci\u00f3n hay que tener en cuenta las capacidades del PLC utilizado, ya que la naturaleza electromec\u00e1nica de los dispositivos conectados a \u00e9l puede no ser capaz de seguir el ritmo de las instrucciones, y puede parecer que se saltan algunas reglas cuando los dispositivos realmente no pueden seguir el ritmo.<\/p>\n<p>La l\u00f3gica de escalera <strong>se utiliza mucho en entornos industriales para programar PLC en los que se requiere un control secuencial de los procesos y operaciones de fabricaci\u00f3n.<\/strong><\/p>\n<p>El lenguaje de programaci\u00f3n es muy \u00fatil para programar sistemas sencillos pero cr\u00edticos o para transformar sistemas antiguos cableados en otros m\u00e1s nuevos programables. Tambi\u00e9n se utiliza mucho en sistemas de <a href=\"https:\/\/www.techopedia.com\/es\/definicion\/automatizacion\">automatizaci\u00f3n<\/a> muy sofisticados, como f\u00e1bricas de electr\u00f3nica y autom\u00f3viles.<\/p>\n<p>La idea que subyace a la l\u00f3gica de escalera es que<strong> incluso el personal sin conocimientos de programaci\u00f3n puede programar r\u00e1pidamente<\/strong>, ya que utiliza s\u00edmbolos de ingenier\u00eda convencionales y familiares para la programaci\u00f3n.<\/p>\n<p>La ventaja descrita anteriormente se ve r\u00e1pidamente anulada, ya que los fabricantes de PLC suelen proporcionar tambi\u00e9n sistemas de programaci\u00f3n de l\u00f3gica de escalera con sus productos, que a veces no utilizan los mismos s\u00edmbolos y convenciones que los de otros modelos de PLC de otros fabricantes.<\/p>\n<p>Esto debido a que el sistema de programaci\u00f3n suele estar pensado s\u00f3lo para modelos concretos, por lo que los programas no se pueden portar f\u00e1cilmente a otros modelos de PLC o hay que reescribirlos directamente.<\/p>\n","protected":false},"excerpt":{"rendered":"<p>\u00bfQu\u00e9 significa l\u00f3gica de escalera?
