Construct a simulated program for the ladder logic program of Figure 9-18. Enter the program into the PLC. Operate the program to force specified inputs and outputs according to the following sequence: a) Turn switches 1 and 2 off and switch 3 on. b) Force off switch 3. Use the data monitor to observe the status of the corresponding bit for switch 3 in the input image table file. Close switch 3 and observe the status of the bit. How does forcing inputs manipulate the input image table file bits? Disable the force, and exit from the data monitor to the ladder logic screen. c) With all switches turned off, force on pilot light 2. Use the data monitor to observe the status of the corresponding bit for pilot light 2 in the output image table file. How does forcing outputs manipulate the output image table file bits?
