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

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.

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
