Signal Logging with MATLAB
To log signal values and times, mark signals for logging with the Simulation Data Inspector or add a File Log to your model.
A File Log block collects signal data on the target computer that is sent to the development computer after each simulation run. Or, if the target computer is not connected to the development computer, you can upload the data to the development computer when you connect to the target computer.
Objects
Target | Represent real-time application and target computer status |
Target.FileLog | Target Computer file logger |
Instrument | Create real-time instrument object |
slrealtime.instrument.LineStyle | Create real-time instrument LineStyle object |
Functions
discard | Delete file log data from target computer |
list | Get information about available file logs of signal data |
import | Import file log data from target computer |
slrealtime.fileLogImport | After copying file logs from target to development computer, import file logs into Simulation Data Inspector |
slrealtime.fileLogList | After copying file logs from target to development computer, list available file logs for import into Simulation Data Inspector |
startRecording | Starts signal data live streaming and File Log logging |
stopRecording | Stops signal data live streaming and File Log logging |
