How to pass values to S function through Mask Dialog and use those values in Processor-in-the Loop mode and external mode?

Hello,

I have logic algorithm written in a S-function builder. I need to let the user pass values using a Mask Dialog to the S-Function which has to execute on the hardware or run in the PIL mode.

Example:

A parameter named "Speed" whose value I want to obtain from the Mask Dialog needs to be read inside the S-Function builder and perform appropriate action based on the value of "Speed".

How can this be achieved? Thanks in advance.
