How to use "from workspace" in the same Simulink model as internal parameter in a block?

Hi all, I've the model in figure:

I want to use "value.Data" (it's a timeseries, output of SYSTEM block) in other two blocks:

-in "unit delay" block as sample-time (for example, you can suppose that "value" is a frequency factor that changes during simulation time by SYSTEM block).

-in "gain" block as Gain (you can suppose that Gain block is any block, not a specific gain block, this is only to sinplify the question).

NOTE: "value" changes during simulation time as output of SYSTEM block, and so, I can't start a simulation with default values and then re-start simulation with the precedent values of "value" timeseries. I want to use "value" in the others blocks during the same simulation.

Thanks
