Error evaluating parameter 'Scale' in component MPC_GFI - real/Plant (inverter)/Vs: structure has no member 'Vs'.

Hello,

I want to take a voltage using an ‘analog output signal’ from a ‘3-phase meter block’ connected to a ‘3-phase inverter’.

I essentially want to take the output voltage from the inverter subsystem so it can input to another subsystem as a signal named voltage source (Vs).

The problem persists in the ‘analog output signal’ block ‘scale: 5/Par.IM.Vs’. I get the following error:

Error evaluating parameter ‘Scale’ in component MPC_GFI - real/Plant (inverter)/Vs: structure has no member ‘Vs’.

How can I create a structure or where can I define it, so I don’t get this error?

Another thing to have in mind that was already on the download model, another ‘analog output signal’ block taking current from a ‘3-phase meter’ work just fine, scale: 5/Par.IM.Is. I just want to do the same thing but with voltage.

Giovanni, can you post your model or one that shows the representative issue? It is likely a problem specific to your model Initialization commands.
