Las l\u00edneas de producci\u00f3n de este cliente contaban con relojes instalados en algunos puntos de la l\u00ednea para poder indicar a los operarios tareas que se ten\u00edan que hacer en una hora espec\u00edfica del turno. El problema era que no exist\u00eda coordinaci\u00f3n entre ellos lo que generaba que no fueran confiables para indicar la hora a lo largo de toda la l\u00ednea (m\u00e1s de 100mts). Adem\u00e1s, algunos de ellos perd\u00edan su ajuste llegando a haber diferencias considerables (m\u00e1s de 15 min) entre relojes consecutivos y deb\u00edan ser reparados con una alta frecuencia debido a que se basaban en leds, a esto se agrega que no exist\u00eda una forma centralizada de modificar la hora a todos los relojes.<\/p>\n\n\n\n
Nos plantean la necesidad de solucionar este problema de forma definitiva, realizamos an\u00e1lisis de la soluci\u00f3n bas\u00e1ndonos en componentes que puedan encontrarse en plaza. Luego de investigar varias formas de abordar el problema concluimos en ofrecer dos servidores HMI redundantes de la marca Weintek (plaza), monitores con puerto HDMI de 32\u201d y 43\u201d de la marca Dahaus (plaza), conversores HDMI a ethernet debido a que las distancias que se deb\u00edan alcanzar eran mayores al m\u00e1ximo permitido por el protocolo HDMI.<\/p>\n\n\n\n
Para realizar la coordinaci\u00f3n de todos los relojes se configuran ambos HMI para que \u201cbusquen\u201d la hora en el servidor de hora central de planta (administrado por el cliente) a trav\u00e9s del protocolo SNTP. Adem\u00e1s, se instala PLC para realizar el encendido de sirenas localizadas en la l\u00ednea para indicar que se deben realizar ciertas tareas.<\/p>\n\n\n\n
Todas las \u00e1reas necesarias para la instalaci\u00f3n de este sistema a nivel de programaci\u00f3n (HMI y PLC), visualizaci\u00f3n (HDMI), el\u00e9ctrica(tablero), electr\u00f3nica(dise\u00f1o) y mec\u00e1nica(soporteria) fueron realizadas por LKT, por lo tanto, en este caso se dio una soluci\u00f3n llave en mano.<\/p>\n","protected":false},"excerpt":{"rendered":"
