Data acquisition problem in Simulink model

1 次查看(过去 30 天)
Hello,
I have created a Simulink model in order to acquire temperature measurements from a sensor. I launch the simulation and it runs even for several hours without problems until I decide to stop it. The strange thing happens when I relaunch the simulation: the software seems to read only one measurement and then it automatically stops without errors.
The only solution I found is to rewrite from zero the model. What does it mean? Could be a corrupted file or something?
Can anyone help me? Thank you
Chiara

Hi Chiara,
The issue where a Simulink model stops running properly after the first successful execution could be due to several factors, not necessarily a corrupted file. Consider these potential causes and solutions:
  • Ensure hardware resources are properly released after simulation. Add cleanup commands for hardware interfaces.
  • Check for initialization steps that may not repeat on subsequent runs. Use the "StartFcn" callback for necessary re-initialization.
  • Review and adjust solver settings. Ensure settings are correctly applied for each run.
  • Update your Simulink and MATLAB to the latest version to avoid known bugs.
  • Less likely if the model runs correctly initially. Regularly back up your model and try exporting it to a new file.
  • Simplify the model to pinpoint the problem.
These steps should help diagnose and potentially resolve the unusual behavior of your Simulink model.
