NWIO-01 Watchdog & I/O es una unidad opcional de E/S digital. Contiene una lógica de vigilancia para supervisar el funcionamiento del AC 800M y el software CI858. La unidad tiene dos entradas digitales (24 VDC o 115/230 VAC) y dos salidas digitales. Usando un interruptor deslizante en la parte superior de la unidad, se puede conectar la lógica de vigilancia para controlar el estado de la salida digital DO2.

El guardián supervisa las siguientes operaciones del CI858:

  • Funcionamiento del programa de aplicación CI858.
  • Comunicación a través de la memoria de doble puerto.
  • Funcionamiento del sistema operativo CI858.
  • Comunicación en el anillo de E/S óptico

El ajuste de fábrica de la constante de tiempo de vigilancia es de 1 s pero se puede acortar a 0,2 s con el puente X1 dentro de la unidad:

  • X1, pines 1-2 = 0,2 s
  • X1, pines 3-4 = 1 s

El tiempo de ciclo del oscilador es 2 veces el intervalo de ejecución del NWIO1DO. Debe ser lo suficientemente rápido en comparación con la selección de constante de tiempo en la unidad NWIO-01:

Para una constante de tiempo de 1 s:

  • Intervalo de ejecución de la tarea <100 ms
  • Tiempo de ciclo del oscilador <200 ms

Para una constante de tiempo de 0,2 s:

  • Intervalo de ejecución de la tarea <20 ms
  • Tiempo de ciclo del oscilador <40 ms
