Explicitly stop the block execution via set_param(...)

Hello,
I’m working from the priorityDemon demo:
openExample('simulink_features/BlockPriorityExample').
In my model, I have EEPROM-reading blocks that dispose an operationFinished flag.
Given the priority queue structure shown in the example, is it possible to use a set_param(...) call to explicitly stop a EEPROM-reading block from executing?
Thank you,

Hi Dimitri,
You cannot use set_param to stop a block from executing during simulation—set_param can only change parameters like priority, which affects execution order, not whether the block runs.
To control whether an EEPROM-reading block executes, put it inside an Enabled Subsystem and use your operationFinished flag as the enable signal. This way, the block only runs when enabled.
