Remove default block names from auto generated Code using embedded coder

Hello,

i am autogenerating a PID code from simulink, but in the generated code i get some variable name which correponds to its root level block name.

How can i replace these root level block names by some meaning full names in generated code. For example ,

rtb_DeadZone_0 = rtb_Sum * rtb_Saturation + rtb_DeadZone * rtb_PID_Y_Out_Ratelimited;

OR

if (Select_OL) {

rtb_Sum = (real32_T)OL_X_Command;

rtb_DeadZone = (real32_T)OL_Y_Command;

}

i get above lines of code when i autogenerate it and bit hard to read and understand. How can i replace those autogenerated name like rtb_DeadZone_0 , rtb_Sum etc.

Thank you.

If you want a particular variable name for a signal line in the model, double click the signal line, give it a name "MySignal", right click, select properties, chck "signal name must resolve to Simulink object". In base workspace, create a Simulink.Signal object, MySignal=Simulink.Signal. Then, set properties.

open MySignal

Thanks Fangjun,

But i see the name of the sub blocks appearing in the code, these blocks are inside PID block which is available in simulink. Inside these built-in block i cant change the signal name. Do you any siggestion?

Thank you.

The place to change is Ctrl+E, Code Generation, Identifiers. Change Local block output variables from rtb_$N$M to something else. But you don't have specifiic control, just one type of auto naming to another. Right click, select "what's this?" to see the meaning of those $ symbols.

There should be no problem if you break the link of the PID controller and label the signals inside, especially if you want to control the generated signal names.
