Wait For Debounce (G Dataflow)

Version:
    Last Modified: September 16, 2017

    Waits for all of the switches in the Switch Executive virtual device to debounce.

    The outputs of this node do not return until either the switching system is completely debounced and settled or the maximum time has elapsed and the system is not yet debounced. In the event that the maximum time elapses before the relay has switched and debounced, Wait For Debounce returns an error indicating that a timeout has occurred.

    Programming Patterns
    To ensure that all of the switches have settled, call Wait For Debounce after a series of connection or disconnection operations and before taking any measurements of the signals connected to the switching system.

    session in

    Handle that identifies your Switch Executive virtual device session previously allocated by Open Session.

    datatype_icon

    error in

    Error conditions that occur before this node runs.

    The node responds to this input according to standard error behavior.

    Standard Error Behavior

    Many nodes provide an error in input and an error out output so that the node can respond to and communicate errors that occur while code is running. The value of error in specifies whether an error occurred before the node runs. Most nodes respond to values of error in in a standard, predictable way.

    error in does not contain an error error in contains an error
    If no error occurred before the node runs, the node begins execution normally.

    If no error occurs while the node runs, it returns no error. If an error does occur while the node runs, it returns that error information as error out.

    If an error occurred before the node runs, the node does not execute. Instead, it returns the error in value as error out.

    Default: No error

    datatype_icon

    maximum time

    Amount of time to wait (in milliseconds) for the debounce to complete.

    With a value of 0, this input checks for debouncing once, and the node returns an error if the system is not debounced at that time. With a value of -1, this input waits for an infinite period of time until the system is debounced.

    session out

    Reference to your virtual device session to wire to the next node.

    datatype_icon

    error out

    Error information.

    The node produces this output according to standard error behavior.
