Real-Time Shared Variable Error Codes
Shared Variables can return the following error codes when the Real-Time FIFO is enabled. Refer to the KnowledgeBase for more information about correcting errors in LabVIEW.
| Code | Description |
|---|---|
| —2220 | The variable RT FIFO read buffer is empty. There is no available data to read. |
| —2221 | The variable RT FIFO write buffer is full. The oldest data point in the buffer is overwritten. |
| —2223 | The Variable Client Support software required by the shared variable is missing or of the wrong version. Ensure that you have installed the correct version of the Variable Client Support software on the RT target using MAX. |
