Hello, I am trying the trial of the Simulink PLC Coder. It runs well if the Matlab block doesn't include variable-size arrays. But if I add variable-size arrays, it shows me that " Variable-size arrays are currently disabled for code generation. Consider selecting the 'Support variable-size signals' option on the Configuration Parameters > Code Generation > Interface page. " I tried to do what it said. But I couldn't find the item it shows me. I don't know if the trial version allow me to use the variable-size arrays. If you know anything, please reply me. Thank you very much!!!!!!!!

Please help. I have the same issue, as well. I can't locate the option suggested in the menu. I looked online for a solution but there is no documentation on this.

Unfortunately Simulink PLC Coder does not support variable-size signals as outlined here:
