open R2017a Simulink Model into R2015b

I have a model that is done in MATLAB Simulink R2017a and I want to open it in MATLAB Simulink R2015b. Unfortunately, I don't have 2017 version so I can export it to previous version. is there any way for doing this?

[Walter Roberson]

If you can attach the model (and it is not a commercial model) then I can convert it for you.

Merhaba, 2017 b de kaydedilmiş simulink dosyasını 2016 b de açmam gerekiyor. Yardımcı olur musunuz?

Hi, Could somebody convert my 2017a simulink model to 2015a version and share? I am unable to do it. Thanks in advance.

Simulink has a preference, in the Model File section, called "Do not load models created with a newer version of Simulink". You can temporarily turn this off rather than edit the model files to change version numbers.

If the model uses only basic blocks then it might be possible to load it in R2017b, but it could also crash MATLAB. As others have commented, using the "Export to Previous Version" feature is the supported way to take a model from a later release to an earlier one.

Remember to turn the preference "Do not load models created with a newer version of Simulink" back on afterwards.

Hello, I think that that the link could be useful in order to solve your problem: https://it.mathworks.com/matlabcentral/answers/94724-how-can-i-open-my-current-simulink-models-in-previous-versions-of-simulink

Unfortunately the solution there requires access to a MATLAB Simulink version at least as new as the one used to create the file.

[Marco]

Yes, you are right. The only possibility is to have a newer version of Matlab.
