Writing a Value to a Citadel Trace

You can use the Write Trace VI to append a data point to a Citadel trace. Complete the following steps to write a value:

1. Add the Write Trace VI on the block diagram.
2. Wire the trace reference output of the Open Trace VI to the trace reference input of the Write Trace VI.
3. Wire the value and timestamp inputs of the Write Trace VI.
   Leave the timestamp input unwired to use the current time. The Write Trace VI fails if the timestamp input is earlier than the timestamp of the last point written to the trace. You can determine the timestamp of the last point in the trace using the Get Trace Info VI.
