The value you wire to History Size determines the number of times the loop iterates before the Express VI returns data. For example, if you enter 1 in History size, the Express VI does not return the data wired to the Signals input after the first iteration of the loop. The second time the loop iterates, the Express VI returns the value from the first iteration of the loop. The third time the loop iterates, the Express VI returns the value from the second iteration of the loop.
