Logging Blocks

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

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

Blocks

File LogWrite signal data file log on target computer
Enable File LogEnable or disable file logging of signals on target computer

Objects

TargetRepresent real-time application and target computer status
Target.FileLogTarget Computer file logger
TargetsConfigure and manage target objects
InstrumentCreate real-time instrument object

Properties

Target Object Propertiesslrealtime Target object properties for configuration and status

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 Inport in Referenced Model

Investigate issues that prevent some signals from streaming to the Simulation Data Inspector.

Troubleshoot Signal Data Logging from Inport in Referenced Model in Test Harness

Investigate issues that can occur when signal data logging from signals in referenced models in test harnesses.

Troubleshoot Signal Data Logging from Send and Receive Blocks

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

Troubleshoot Signals for Streaming or File Logging

Investigate issues related to an error that a signal cannot be streamed or logged.
