By pressing the start button: motors M1, M2, and M3 all run together. After 3 seconds: M1 stops and M4 starts. After 3 seconds: M2 stops and M1 starts. After 3 seconds: M3 stops and M2 starts. After 3 seconds: M4 stops and M3 starts. This cycle repeats continuously (a rotation among the 4 motors, with 3 always running at the same time, and every 3 seconds one motor changes). There are three important execution conditions: Without using a comparator instruction. The start button has no effect after the process begins (it is not a stop button). State must be preserved when stopping (resume from the last state when restarted). Implementation is required using a Ladder Diagram.

Crea un diagrama de Ishikawa (espina de pescado / fishbone diagram) en formato horizontal, estilo profesional y limpio, en tonos verdes, azules y grises corporativos. En la cabeza del pez (extremo derecho), coloca el efecto/problema principal en un recuadro destacado: "Deficiente gestión del sistema de almacenamiento en la cadena de suministro del coco: pérdida de trazabilidad, deterioro de producto y cuellos de botella operativos" La espina central debe tener 6 espinas diagonales (3 arriba, 3 abajo), cada una representando una categoría de las 6M, con su lista de causas en texto pequeño junto a cada espina: Espinas superiores: Mano de Obra — Falta de capacitación en manejo de perecederos y FIFO · Ausencia de turnos programados · Alta rotación de personal Métodos — Sin procedimiento estandarizado de codificación FIFO · Sin programación de citas de camiones · Sin protocolo de control de temperatura Maquinaria — Cámaras de refrigeración sin mantenimiento preventivo · Sin sensores de monitoreo en tiempo real · Montacargas insuficientes Espinas inferiores: Materiales — Empaques sin codificación de vencimiento/lote · Pallets no estandarizados · Sin tecnología de trazabilidad (RFID/QR) Medición — Sin KPIs en tiempo real de temperatura y ocupación · Sin indicador de mermas · Sin sistema WMS Medio Ambiente — Altas temperaturas de la Costa Caribe · Almacén sin diseño térmico óptimo · Estacionalidad de cosecha genera picos de llegada Usa íconos pequeños junto a cada categoría (persona para Mano de Obra, engranaje para Métodos, máquina para Maquinaria, caja para Materiales, gráfico para Medición, hoja/termómetro para Medio Ambiente). Incluye un título en la parte superior: "Diagrama de Ishikawa – Cadena de Suministro del Coco" y un pie de página pequeño: "Elaborado por: Mario – UNAD". Estilo: diagrama técnico de análisis causa-efecto, formato horizontal apto para insertar en documento Word o PDF, con espacio suficiente para leer el texto de cada causa.
