XNET Convert (Signal to Frame » LIN) (G Dataflow)
Converts between NI-XNET signals and LIN frame data.

session in
The session to read. This session is returned from XNET Create Session. The session mode must be Conversion.
signal data
An input that returns a one-dimensional array of signal values. Each signal value is scaled, 64-bit floating point. Each array element corresponds to a signal configured for the session. The order of signals in the array corresponds to the order in the session list.
The data provides the value for the next conversion of each signal.
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.
Default: No error
session out
An output that is the same as session in, provided for use with subsequent nodes.
unused payloads
This parameter is empty. No user input is needed.
frame data
Returns the array of LabVIEW clusters. Each array element corresponds to a frame the session converted.
The elements of each cluster are specific to the LIN protocol.
identifier
The identifier received within the frame's header. The identifier is a number from 0 to 63.
If the schedule entry (slot) is unconditional or sporadic, this identifies the payload data (LIN frame). If the schedule entry is event triggered, this identifies the schedule entry itself, and the protected ID contained in the first payload byte identifies the payload.
event slot?
This element is not used. This element is false.
event ID
This element is not used. This element is 0.
echo?
A Boolean value that determines whether the frame was an echo of a successful transmit (true), or received from the network (false). For conversion, it is always set to false.
type
timestamp
An element that represents the absolute time when the XNET interface received the frame (end of frame), accurate to microseconds. The timestamp returned by the conversion is always invalid (0).
payload
The array of data bytes for the LIN data frame. The array size indicates the received frame’s payload length.
According to the LIN protocol, this payload is 0-8 bytes in length.
error out
Error information.
The node produces this output 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.
Where This Node Can Run:
Desktop OS: Windows
FPGA: Supported
Web Server: Not supported in VIs that run in a web application
