Programmatically comment blocks residing in a subsystem

Hi,

I am trying to programmatically comment some subsystem blocks in my model. Here I have shown a simplified version of in the attached model file. ( actual number of subsystem block is in 100s)

Subsytem1 has: E7kW_Medium Range1, E7kW_Long Range1

Subsytem2 has: E7kW_Medium Range2 , E7kW_Long Range2

clc

clear all

open_system('Commenting_Programmatic')

Num_7L=2

Num_7M= 2

Status_7L= 'on'; % Comment status

Status_7M= 'on';

for kk= 1: Num_7L

set_param([gcb,'/E7kW_Long Range',num2str(kk),''],'Commented',Status_7L)

end

for ll= 1: Num_7M

set_param([gcb,'/E7kW_Medium Range',num2str(ll),''],'Commented',Status_7M)

end

E7kW_Medium Range1 gets commented out, but E7kW_ Medium Range2 ( residing in Subsystem2) gives error , as the gcb still reads the previous location w.rt Subsystem1.

If I put the EV subsystem in model root, then commenting works fine. But how can I get address of the block when it is residing in separate subsystems?

Thanks,

Haroon

@cowboy safari You might want to build the full path dynamically instead of relying on gcb. For example, use find_system with filters to locate all blocks matching your naming pattern, then loop through those paths and set the Commented parameter. That way it works no matter which subsystem they’re in.

Corrected code with asociated simulink file is here:

clc

clear all

load_system('Commenting_Programmatic')

Num_7L=2

Num_7M= 2

Status_7L= 'on'; % Comment status

Status_7M= 'off';

for kk= 1: Num_7L

EV_7L_names= strcat('E7kW_Long Range',num2str(kk));

fullnames= getfullname(Simulink.findBlocks('Commenting_Programmatic','Name',EV_7L_names));

path= string(fullnames);

set_param(path,'Commented',Status_7L)

end

for ll= 1: Num_7M

EV_7M_names= strcat('E7kW_Medium Range',num2str(ll));

fullnames= getfullname(Simulink.findBlocks('Commenting_Programmatic','Name',EV_7M_names));

path= string(fullnames);

set_param(path,'Commented',Status_7M)

end

If doing it programmingly, never use "gcb" or "gcs". Instead, use the full block path like "RootModelName/SubSystemName/BlockName". If the "SubSystemName" is varying, then use find_system() to find the SubSystem block and get its name.

Thanks for the comment. But I was not able to find the specific varying subsystem name using find_system.

Though Simulink.findBlocks did the job.

fullnames= getfullname(Simulink.findBlocks('Commenting_Programmatic','Name',EV_7L_names));

path= string(fullnames);

set_param(path,'Commented',Status_7L)

end

fullnames= getfullname(Simulink.findBlocks('Commenting_Programmatic','Name',EV_7M_names));

path= string(fullnames);

set_param(path,'Commented',Status_7M)

end
