How to programmatically find the port types of the blocks

5 views (last 30 days)
According to the documentation , "PortConnectivity" parameter of the block has a field "type" which should either return the type (enable, state ...) or number(if it is a data port).
However testing it on Enabled Delay block from Simulink library, the input ports "type" field is 1 and 2 instead of 1 and "enable". Is this a documentation error, api error or my misunderstanding?
get_param(block_name_fp,"PortConnectivity")

It is under Simulink/Discrete. I want to know which source block's port is connected to a destination block port. For example, says there are two constant block connected to enabled delay block. I want to know if ConstantA is conncted to data port and ConstantB is connceted to Enable port.
In my particular scenario, I also have to know the block type of the each of the block. Given different variation of the Delay block is returned as Delay by
get_param(<BLOCK>,"blocktype")
I was just confused how to know the port connection between blocks programatically.

Well, it does appear that there are several blocks in the Discrete library that all have BlockType == 'Delay'
As far as I can tell, and I might be wrong, the only way to distinguish how each is configured is to interrogate other parameters of the block, like
get_param(gcb,'ShowEnablePort')
to determine which input ports are "active" (I can't think of a better word) and go from there.

This clarifies the confusion.
