How to use From Workspace block in Cyclic Repetition Mode?

I have 1000 values in excel file.

I need to Plot or Display these 1000 values in Cyclic Repetition Mode.

I imported these values in simin of From Workspace block. 1000 values are displaying. But when ever i got 1000th value the count should start from 1st value. Like that Cyclic Repetition should happen. These values i will give to Analog Board to produce a sine wave continuously.

I declared 1000 values in Array format. But for cyc. rep.i should declare these in structured format but i don't know how to declare.

So plz support my problem. As it is so important to me.

Thanks in advance.
