XNET Read (Signal Single-point) VI

session in is the session to read. This session is selected from the LabVIEW project or returned from the XNET Create Session VI. The session mode must be Signal Input Single-Point.

The error in cluster can accept error information wired from VIs previously called. Use this information to decide if any functionality should be bypassed in the event of errors from other VIs. The pop-up option Explain Error (or Explain Warning) gives more information about the error displayed.

session out is the same as session in, provided for use with subsequent VIs.

data 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 returns the most recent value received for each signal. If multiple frames for a signal are received since the previous call to the XNET Read (Signal Single-Point) VI (or session start), only signal data from the most recent frame is returned. If no frame is received for the corresponding signals since you started the session, the signal Default Value is returned. For an example of how this data applies to network traffic, refer to Signal Input Single-Point Mode. A trigger signal returns a value of 1.0 or 0.0, depending on whether its frame arrived since the last Read (or Start) or not. For more information about trigger signals, refer to Signal Input Single-Point Mode.

The error out cluster passes error or warning information out of a VI to be used by other VIs. The pop-up option Explain Error (or Explain Warning) gives more information about the error displayed.
