8. Arrange your blocks with comments in the design space as shown in
Figure 82.
Note:
Even in graphical programming, comments are especially helpful
in describing the logic used in the program. Place specific
comments near the blocks they are describing. Otherwise, place
general program notes in one location as in Figure 82.
9. Compile and save your program to check for errors and to preserve
your work.
Figure 83 on page 77 is the cooling tower with two-speed fan program. Go
to Chapter 5, “Cooling tower with variable-speed fan example” to add the
condenser water pump module and to modify your program.
