XNET Write (State » FlexRay Symbol) (G Dataflow)

Last Modified: November 2, 2017

Writes a request for the FlexRay interface to transmit a symbol on the FlexRay bus. You can use this XNET Write node with any input or output session for FlexRay.

connector_pane_image
datatype_icon

session in

The session to use for the symbol write. This session is selected from the LabVIEW project or returned from XNET Create Session. The session must use a FlexRay interface.

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

session out

An output that is the same as session in, provided for use with subsequent nodes.

datatype_icon

error out

Error information.

The node produces this output according to standard error behavior.

Description

You can use XNET Write (State FlexRay Symbol) with any XNET session mode, as long as the session interface is FlexRay. Because the symbol write applies to the FlexRay interface, it can apply to multiple sessions.

After calling XNET Write (State FlexRay Symbol), the XNET interface transmits the symbol during the symbol window of the FlexRay cycle following the currently executing cycle. If you call XNET Write (State FlexRay Symbol) multiple times, only the most recent symbol is transmitted.

Where This Node Can Run:

Desktop OS: Windows

FPGA: Supported

Web Server: Not supported in VIs that run in a web application
