Hi @tan boonmee,

I have created and uploaded an example file with an "Out Bus Element Block" and shown how to access the "Data Type" in the following code:

open_system("example");
block = Simulink.findBlocksOfType(bdroot,'Outport');
portname = get_param(block(1),'PortName');
% Here, we have only one Outport, you might need to modify in order to specify 
% which block corresponds to Out Bus Element
param = get_param([bdroot '/' portname '.Signal.signal1'],'DataType')
param = 'int64'
close_system(bdroot)

Further, you can use the following documentation which illustrates the ability to set a parameter, and use the convention to get parameters too:

Hope this helps!

Hi,

To programmatically obtain the data type attribute value of an In Bus Element, the function “get_param” should be used. The data type attribute value of an “In Bus Element” corresponds to the parameter ‘OutDataTypeStr’. This parameter should be passed to the “get_param” function, to programmatically obtain the data type of the bus element. For more information, refer to this documentation link of the function “get_param” - https://www.mathworks.com/help/simulink/slref/get_param.html.

get_param("<path_to_OutBus>/OutBus.NestedBus.Chirp", "OutDataTypeStr")

Note: Modify the path so that it corresponds to the correct location of “OutBus” in your model.

Please refer to this documentation link for more details on programmatically accessing attributes of the In Bus Element - https://www.mathworks.com/help/simulink/slref/inbuselement.html#:~:text=elements%0Ano%20default-,Attributes,-To%20specify%20attributes

Hope this helps!
