The counter program of Figure 11-28 is described in the text. a) Prepare an I/O connection diagram and ladder logic program that will simulate its operation. Use addresses that apply to your PLC installation. Enter the program into the PLC, and verify its operation. b) Modify the program so that a second light comes on when the accumulated count of the two counters is equal to 345 and remains on until the reset button is pressed. Enter the modified program into the PLC, and prove its operation
