Goto/From connections cannot cross nonvirtual subsystem boundaries. The only exception is when a goto is connected to a state output port

Hi all,

I have goto Tags placed within a Triggered subsystem, with their corresponding from Tags in the highest level of the simulink model.

However, I received the error 'Goto/From connections cannot cross nonvirtual subsystem boundaries. The only exception is when a goto is connected to a state output port'.

May I know how can I go about solving this problem?

Any help is greatly appreciated!

Best Regards, Rachel

Goto/From are a pain in the ass. Do not use them, never. Especially in their "global" form, which is terrible.

Goto/From are just a bypass for when people are not capable to make clean model, same apply with C/C++ and global variables.

The error message is clear... don't place GoTo block inside the triggered subsystem and corresponding From block outside.

Use normal signals instead to exist the triggered subsystem.

An atomic subsystem must execute everything that is inside in one unit. And GoTo and From are also like one unit. So making one cross the other is incompatible.

Depending on the sample time involved, if you really do not want to see a signal line, maybe global Data Store Read and Write could help.

Hi Rouleau, thanks for the reply.

I tried to follow your suggestion on using Data Store Read and Write, and received the following error:

Invalid setting for input port dimensions of 'microgridInput_dataRW/VSC Controller (Station 1)/Anti-aliasing Filters/Demux5'. The dimensions are being set to 1. This is not valid because the total number of input and output elements are not the same

May I know how should I go about solving this problem? Thank you so much for your help, I really appreciate it.

Cheers,

Rach

Just use normal connection. Don't bother using goto or read/write blocks . This make your model harder to read, but if you want to pass signal inside triggered/function call subsystem, you got no other choice. Good luck
