The Real-Time FIFO functions can return the following error codes. Refer to the KnowledgeBase for more information about correcting errors in LabVIEW.

Code Description
−2211 There was an attempt to create a Refnum to an existing RT FIFO using inconsistent Read/Write modes. There was an attempt to create a Refnum to an existing RT FIFO using inconsistent Read/Write modes. All calls to RT FIFO Create using the same name require the same Read/Write modes.
−2209 The required RT FIFO DLL function is not bound. The required RT FIFO DLL function is not bound. The DLL cannot be found or is missing the function.
−2208 This version of LabVIEW does not support waveforms in an RT FIFO. This version of LabVIEW does not support waveforms in an RT FIFO. Use LabVIEW 7.1 or later instead.
−2207 Invalid waveform passed to the RT FIFO.
−2206 RT FIFO does not exist.
−2205 RT FIFO must contain at least two elements.
−2204 Type mismatch. The named RT FIFO type does not match the type of the existing RT FIFO with the same name.
−2203 Cannot match an empty name.
−2202 The specified name does not exist.
−2201 The specified name already exists and is of a different size or type.
−2200 Unknown internal error.
