What it does | This microblock defines the minimum amount of time that a signal should remain on or off. For example, this microblock can be used to prevent an on/off signal from rapid fluctuations that could affect equipment performance. When the microblock receives an on signal, the output turns on and remains on for the amount of time defined in the Minimum on time field. When this time expires, the output either remains on if the input is on, or turns off if the input is off. Likewise, when the microblock receives an off signal, the output turns off and remains off for the amount of time defined in the Minimum off time field. When this time expires, the microblock's output either remains off if the input is off, or turns on if the input is on.
