When the simulation runs, the Signal Scope block opens a window containing a plot. The horizontal axis represents the times at which entities depart from the server, while the vertical axis represents the total number of entities that have departed from the server.
After an entity departs from the Single Server block, the block updates its output signal at the #d port. The updated values are reflected in the plot and highlighted with plotting markers. From the plot, you can make these observations:
· Until T=1, no entities depart from the server. This is because it takes one second for the server to process the first entity.
· Starting at T=1, the plot is a stairstep plot. The stairs have height 1 because the server processes one entity at a time, so entities depart one at a time. The stairs have width equal to the constant service time, which is one second.
