Read Binary (G Dataflow)

Last Modified: February 26, 2020

Returns the next available message. If no message is available, the node waits for either a new message or for the specified timeout to elapse.

If the WebSocket session becomes invalid, then the node stops waiting and returns an error.

connector_pane_image
datatype_icon

websocket session in

Unique value that identifies the websocket session.

datatype_icon

timeout

Time, in seconds, that this node waits for a new message to be available before returning a timeout error. A value of -1 indicates to wait indefinitely.

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

websocket session out

Unique value that identifies the websocket session. Use this value to refer to this websocket session in subsequent node calls.

datatype_icon

binary response

The next message available as binary data.

datatype_icon

error out

Error information.

The node produces this output according to standard error behavior.

Web Server: Supported in VIs that run in a web application
