Logging

Simulation Data Inspector, Simulink Scope blocks, File Log blocks, target computer access, profiling

To observe the behavior of your real-time application and the target computer on which it is running, use logging and profiling blocks.

Blocks

File Log	Write signal data file log on target computer
Enable File Log	Enable or disable file logging of signals on target computer
Enable Profiler	Start and stop execution profiler on target computer
Log Event	Log an execution profiling event

Objects

`Target`	Represent real-time application and target computer status
`Target.FileLog`	Target Computer file logger
`Targets`	Configure and manage target objects
`ProfilerData`	Data returned from profiler
`Instrument`	Create real-time instrument object

Functions

`enable`	Start file logging of signal data
`disable`	Stop file logging of signal data
`list`	Get information about available file logs of signal data
`import`	Import file log data from target computer
`abort`	Abort file log data import from target computer
`discard`	Delete file log data from target computer
`startProfiler`	Start profiling service on target computer
`stopProfiler`	Stop profiling service on target computer
`getProfilerData`	Retrieve profile data object
`resetProfiler`	Reset profiling service state to `Ready`

Troubleshooting

Troubleshoot Signal Data Logging from Nonvirtual Bus, Fixed-Point, and Multidimensional Signals

Investigate issues that can occur when signal data logging from signals in nonvirtual buses, signals with fixed-point data type, and multidimensional signals.

Troubleshoot Signal Data Logging from Send and Receive Blocks

Investigate issues that can occur when signal data logging from Send and Receive blocks.

Featured Examples

Parameter Tuning and Data Logging

Use real-time parameter tuning and data logging with Simulink® Real-Time™. After the example builds the model and downloads the real-time application, slrt_ex_param_tuning, to the target computer, the example executes multiple runs with the gain 'Gain1/Gain' changed (tuned) before each run. The gain sweeps from 0.1 to 0.7 in steps of 0.05.
