FP_INTERRUPT_ENABLE

Habilitar programas de interrupción

Esta instrucción FP habilita la ejecución de todos los programas asignados a tareas de interrupción.

Observaciones

  • En el caso de interrupciones periódicas, se aplica lo siguiente: Después de habilitar los programas de interrupción, la primera ejecución de un programa de interrupción puede producirse una vez transcurrido el intervalo de tiempo que se ha definido para el mismo.

  • Cuando el PLC pasa del modo PROG al modo RUN, los programas de interrupción se deshabilitan. Es necesario habilitar los programas de interrupción ejecutando FP_INTERRUPT_ACTIVATE.
