Replacing Blocks in Simulink but keep their value

Hello,

I'm runnign the following script for a Simulink model called Replacement_Blocks. I am attempting to replace the constant block found in the generic Simulink library with a certified primitive library that is needed for aerospace development applications.

RepNames = replace_block('Replacement_Blocks','Constant','do178Lib/Simulink/Sources/Constant');

When I run this script the values of the replacement blocks(ones originally with white background) are overwritten. Is there a way to keep the value of the original constant blocks while replacing it with the primitive library equivalent?

You can use :

val = get_param(blk,'Value')

to get the value of the Contant block(s) to be replaced.

Then replace the block(s).

Then use

set_param(RepNames,?,val)  % fill in ? with the correct parmeter for the new block

Should be able to loop over all the block replacement pairs.
