For my 3-phase control system, I am just trying to be able to build this model on my F28p55x controller. I keep running into this error when I try to build it. Having me stuck on about the memory blocks which is holding back my simulation. [3-phase control.plecs](https://forum.plexim.com/uploads/short-url/50spYbH9i1NCD6G5nmTJR2bMk82.plecs) (166.6 KB)

Also for my plant model I am stuck on trying to get the my inverter to plot on the coder which the IGBTS are having an issue with.

I do not see any errors relating to memory blocks in your model. I do notice that your control model is not configured for code generation at all. In order to use the model you must open the **Coder Options + Target** menu and choose the F28P55x target. You also have to choose a step size in the **Coder Options + Scheduling** menu (with `Ts_ctrl` being the logical initial choice).

The question relating to your inverter plot is not clear.

You should also have the controller and plant integrated into a single PLECS model, as all the PLECS RT Box and TI C2000 demo models are structured.
