I want to change output state of delay block to initial value during simulation.

This should happen when that subsystem gets enabled.

But I dont want to change "States when enabling" property to "Reset". Is this possible what enable block do we can do using command prompt? So it will change state of output block as same as when enable subsystem "Reset"

If you use the Unit Delay Resettable block, you should be able to reset it using the reset input port instead.

Yes, I got you point but, I am not allowed to do any changes in the implementation. Otherwise I can simply change the property of its parent enable port as "reset". Is there any way I can achieve that using command line and MATLAB embedded function. MATLAB do this in the background depending upon option selected in enable port mask. Can we do same thing using command line.

Could you explain what you mean by: "MATLAB do this in the background depending upon option selected in enable port mask."

AFAIK, that setting cannot be changed during simulation. If you want to do it before simulation starts, you can of course use:

set_param('path/to/enable/port', 'StatesWhenEnabling', 'reset')

If you can't change that block (library block?), then perhaps you could connect another Enable Subsystem at the output of that block and used the solution I suggested here. Use the same initial condition as that for the library block.
