[Simulink][To Previous Version][Error]

Hey Guys~

I'm trying to convert the model

https://nl.mathworks.com/matlabcentral/fileexchange/70119-back-to-back-hvdc-mmc-for-passive-networks

into matlab 2015a version, but when I run it, I got the error of

The name of Inport block 'I_ph' of the variant block 'BackToBack_HVDC_MMC/Controlsystem for Inverter3/Dq0 Control' must match one of the names of the corresponding Inport blocks of the Variant Subsystem block 'BackToBack_HVDC_MMC/Controlsystem for Inverter3'.

I've compared with the model in two versions and nothing has changed, especially the inport block name,

It would be really great if anyone could point out what is wrong with this :)

Thanks so much!

The name and appearance may look the same. However, the actual path might have changed between releases. Simscape Electrical emerged in R2018b as a merge between Simscape Electronics and Simscape Power Systems. This may be the reason for incompatibility.
