An example of CTU and CTD counters used together is shown in Figure 15-38 and described in the text. a) Prepare an I/O connection diagram and ladder logic program that will simulate its operation. Utilize field devices found on your ControlLogix installation. Enter the program into the controller, and monitor its operation. b) Modify the program to include a red pilot light to indicate entry of a part into the buffer zone and a green pilot light to indicate exit of a part from the buffer zone.
