Adds a value to an Accumulator Tag channel or signals the channel to abort. This endpoint is the same as the Write endpoint except that it has an abort input and an aborted? output. You can use the abort capability of the Accumulator Tag channel to close a channel abruptly, ignoring any data left in the channel buffer. You must use this endpoint together with the Read With Abort endpoint.

Inputs/Outputs

  • csgl.png element —

    element specifies the data to add to the channel.

  • cbool.png abort —

    abort specifies whether to abort this channel. If abort is TRUE, this endpoint marks the channel as closed and ignores further calls to write. Meanwhile, the aborted? output returns TRUE on the next call of this endpoint.

  • iqueuern.png channel —

    channel is the channel wire that connects this endpoint to a reader endpoint.

  • ibool.png aborted? —

    aborted? returns TRUE if abort occurred on this endpoint or the reader endpoints connected to the channel. If aborted? is TRUE, further calls to this endpoint will do nothing except returning aborted? TRUE again.

    • FPGA Module Details

    The following details apply when you use this object in an FPGA VI.

    Note The following details are subject to change with each version of the LabVIEW FPGA Module.
    Single-Cycle Timed Loop Not supported.
    Usage

    For arrays, this endpoint supports only fixed-sized one-dimensional arrays of supported data types. This endpoint does not support variable-sized arrays even if the array resolves to a single size at compile time.

    This endpoint does not support LabVIEW classes.

    If you use this endpoint with the single-precision floating-point data type, refer to the following topics for resource use, latency, and single-cycle Timed Loop support implications.
    Notes A channel terminal of a non-reentrant subVI can be connected to only one channel. If a non-reentrant subVI is called from multiple locations, the channel wires connected to a given terminal must resolve to the same channel at compile time.
