Use your mouse to click on the various switches and note the change in the status color of the terminal that the switch is connected to. The two input cards are addressed as "I:1" and "I:3" while the output cards are addressed "O:2" and "O:4". Likewise two groups of 16 Lights are connected to two output cards of our PLC. Two groups of 16 toggle switches are shown connected to 2 Input cards of our simulated PLC. For this exercise we will be using the I/O simulator section, which consists of 32 switches and lights. 2 The I/O Simulator The simulator screen shown above, should now be in view.
