By now, you should have been up in the PLC lab getting familiar with the HMI and how to program it; how to define new screens, label them, and access them from the F# tabs below; and how to design Icons/Images from the Library that links HMI images to the Final Exam Program you are working on. Here is your FINAL set on Instructions for your Final Exam Program.

1. Create a Main Program Screen (F1) and make a mirror-image layout of the PLC Trainer PB's / Lights (9 items total). Color-code and label your PB's and Switches in the same manner as those found on the Trainer.

2. Since you CANNOT activate a hard-wired Input from the HMI Screen, please use Internal M-bits IN PARALLEL with the associated contacts for the PLC. Start your Internal M-bits at address %M5.0 through %M5.7 (8 outputs total) and proceed upward from there. Example: E-Stop PB is turned ON by hard-wired Input %I0.0 - your Internal M-bit to parallel this Input should be %M5.0. Please look at the PLC Tags Database in your program and design your M-bits accordingly. I will answer questions about this in class and the lab as needed.

3. Create a Diagnostics Screen (F2) and design a section of Program that ‘simulates' a 5-second test of each of the 8 Outputs from Q0.0 through Q0.7 (8 outputs total). Start your Internal M-bits to simulate this at address %M6.0 through %M6.7 (8 outputs total) also. Label each of your new %M6.# bits as "Diagnostics - E-stop Q", for example. Program your HMI Screen to show 8 Lights that are turned ON when each of the 8 Outputs is turned ON for its 5-second interval. I will answer questions about this in class and in the lab.

4. Create an Alarm Screen (F3) do the same thing with the Inputs in the Alarm Condition rung at the end of the program. Start your Internal M-bits for this section of logic at %M7.0 through %M7.7 (limit 8 outputs total). You should have HMI Lights that are turned ON separately if one of the Inputs to the Alarm Condition rung of Logic activates; also put 1 Red Alarm Condition Light in your alarms Screen that activates if that Output turns ON. I will answer questions about this in class and in the lab.

When you are done with these Instructions, you should have 3 screens that you can either activate Inputs from, or receive Outputs from your program. This will take some time to complete, so please plan your own time or that of your lab partner accordingly to get this work done. Since this is your LAST change notice, do your best and be ready to present on your respective lab night. Thank You for the great work you are doing!
