Setting parameters of a certain block

In my model ...i have a constant block feeding a summer ...i want the same value given in the constant block to be used as the switch on and switch off point value in a relay block...

How can i do it???

If you wanna change this offline you can use get_param and set_param commands to attain the value from the Constant block and set it for the Relay block. If you would like this to also update during simulation you would need to create a MATLAB S-Function for that. You can find an example for this here:

Is this what you want?

Define a variable in workspace, MyConstant=1, use this "MyConstant" for your Constant block and Relay block.

even your solution is feasible

Thank you,,:)
