Matlab using in sSimulink

Hi,

I want to connect PCM_port to pos CELL input model created by simple code (file.m)

I can not understand why it does not works well.

results in attached pictures

Required result of pic - connection required.

Thank for support.

the following code:

pen_system('Module_arc')
mdl = 'Module_arc';
bat_rec_model = find_system(mdl,'FindAll','on','Name','Module_arc');

   
%%% add Cell - basic CELL_unit:
for i=1:2          %% set two columns
    colPos = 200;  %% spaces between columns
    for v=1:2     %% loop for 13 cells per column
        nl=num2str(v + 2*(i-1));
        if i==1
            AddCell(v) = add_block('CELL_Unit/CELL 1', [mdl,'/CELL ',nl]);
        else
            AddCell(v) = add_block('CELL_Unit2/CELL 1', [mdl,'/CELL ',nl]);
        end
        
        posc = get(AddCell(v),'Position');
        set(AddCell(v),'Position',posc + [100+(i-1)*colPos 120*(v-1)-45 100+(i-1)*colPos 120*(v-1)-45])
        PH_AddCell{v}=get(AddCell(v),'PortHandles');
        
        %%% connect minus to plus ports:
        if v>1
            add_line(mdl,PH_AddCell{v-1}.LConn(2),PH_AddCell{v}.LConn(1),'Autorouting','on');
        end
    end
end


%%% connect the positive port to first CELL (Cell 1):
Plus_2_Cell = find_system(mdl,'LookUnderMasks','All','FindAll','on','Name','POS');
PH_plus2Cell=get(Plus_2_Cell,'PortHandles');
Pos_port= add_line(mdl,PH_plus2Cell.RConn,PH_AddCell{1}.LConn(1,1), 'Autorouting','on');

Hey @Tommy,

In the shared code, the line PH_AddCell{v}=get(AddCell(v),'PortHandles'); only stores port handles for blocks in the current column, which gets overridden with each iteration as i changes. To maintain a matrix of handles, use:

PH_AddCell{v,i}=get(AddCell(v),'PortHandles');

Assumptions for the blocks CELL_Unit/CELL 1 and CELL_Unit2/CELL 1 are as follows:

• In CELL_Unit/CELL 1, port 1 is positive (pos) and port 2 is negative (neg).
• In CELL_Unit2/CELL 1, port 1 is negative (neg) and port 2 is positive (pos).
• Port locations are set to "Left" for both pos and neg in these blocks.

The the two additional connections to the cell array, can finally be indroduced as shown below:

% connect the positive port to first CELL (Cell 1):
Plus_2_Cell = find_system(mdl,'LookUnderMasks','All','FindAll','on','Name','POS');
PH_plus2Cell=get(Plus_2_Cell,'PortHandles');
add_line(mdl,PH_plus2Cell.RConn,PH_AddCell{1,1}.LConn(1,1), 'Autorouting','on');

% connect neg and pos of the two cells in last row
add_line(mdl,PH_AddCell{numRows,1}.LConn(1,2),PH_AddCell{numRows,2}.LConn(1,2), 'Autorouting','on');

Here's the final result:
