Final Exam 2016 Phase II – Change Notice Dear Class: There were some changes made to the I/O Tag names from the Phase I – Change Notice. The corrections are highlighted in RED. Please review that Phase I Change Notice and make the corrections to your Final Exam Program. The current Phase II – Change Notice contains the following new work to be completed: 1. Set up (2) Input Blocks that contains a Value for the Internal Tank Level of the North Tank and the South Tank each. From the initial package of information that you received, set up ladder logic that reads this Value for the tank level, and if the value is below 22 (22’ in the tank) then turn On the respective solenoid for that tank to simulate water entering it. Your logic should simulate a water flow of 1’ of water every 5 seconds, and when the value reaches 28 (28’ in the tank), your respective solenoid should turn Off. If your Value entered is greater than 28 to 31, then the respective solenoid should not turn On (any value greater than 31 is void, as the tank has an External Overflow Tube that allows water to flow outside at 31’). If done correctly, you should be able to enter any Value from 0 to 31 and your logic should simulate filling the tank. Perform this function for both tanks (HINT: do the logic for one tank, verify it works correctly, then copy/paste/relabel the logic for the other tank. Make them separate sections of logic). 2. Set up (1) Input Block that contains a Value to simulate a Fire Alarm condition. You should be able to set a Value of 1, 2, or 3 (initial value should be 0) into your Input Block that simulates a Fire Condition requiring either 1, 2 or 3 DWP’s to come on (in real life, when a FCS Panel energizes and a Fire Pump comes On, the DWP will increase in VFD speed to match the increased water flow needed. If more water is required, then more DWP’s come On). So, if you Input a 1 into your Input Block that means 1 DWP should be running. If a value of 2 or 3 is entered, then 2 or 3 DWP’s should turn On (in Auto mode) to meet the condition required. Also, when you input a value for a Fire Condition, include logic in your North and South Tank Solenoid Valve circuits to turn BOTH solenoids ON during a Fire Condition (in real life, when a Fire Condition is sensed, both tank solenoids turn On to fill the tanks as water is being drawn out for the Fire Condition). 3. Start reviewing the last part of Chapter 7 from the text regarding HMI’s and any YouTube videos you can find that explain how to program an HMI and relate the HMI I/O to your program. That will be the primary focus of the next change to your program. You have @ 2 weeks to get this part of the program done, and I will go over it in class on Tuesday, April 5th to answer any questions you may have. Keep doing your best with this and remember, you have 4 weeks left until your present your Final Exam program at the end of April. 2 Final Exam 2016 Phase 1 Change Notice CONGRATULATIONS! Your initial program design was accepted by Ford FRAP, and you now have the responsibility for designing the complete program that will become your Final Exam Project for the FRAP facility. Since you and your partner already have come up with an initial program (from your Midterm Exam), you are to complete the following steps for this Phase 1 Change Notice: 1. Put together the best possible combination of Ladder Logic from your separate programs into 1 complete program for the Siemens PLC. Configure your program for the correct PLC, the correct Signal Board, and the correct HMI – all this information can be found on the equipment up in the PLC lab. When you complete your initial configuration, call it Final Exam 2016 and make sure each of you has the most updated version of this program. 2. There are only 14 hard-wired Inputs and 10 hard-wired Outputs available on the Siemens PLC. Allocate the following Inputs to the following Tag Names: · I0.0 – E-Stop · I0.1 – Start · I0.2 – DWP Manual · I0.3 – DWP 1 Auto · I0.4 – DWP 2 Auto · I0.5 – DWP 3 Auto · I0.6 – FWAP/NT Solenoid ON · I0.7 – FWAP/ST Solenoid ON · I1.0 – Spare · I1.1 – Reset · I1.2 – DWP 2 Select · I1.3 – DWP 3 Select · I1.4 – FWAP/NT Select · I1.5 – FWAP/ST Select Allocate the following Outputs to the following Tag Names: · Q0.0 – E-stop Q · Q0.1 – Start Q · Q0.2 – FRWS/OK Q · Q0.3 – DWP 1 Q · Q0.4 – DWP 2 Q · Q0.5 – DWP 3 Q · Q0.6 – FWAP/NT Solenoid ON Q · Q0.7 – FWAP/ST Solenoid ON Q · Q1.0 – Spare Q · Q1.1 – Spare Q Final Exam 2016 Phase 1 Change Notice You should probably allocate the above I/O’s first, and remember that this is just an Initial Configuration. There may be changes required as you progress through this project, so just relax and do your best with each step as you go. Your goal at this point is to properly configure your program so that it functions like a self-contained program. Also, you should familiarize yourself with the Internal M-bits in the Siemens TIA, as you will be using these also for your completed program. Remember, this is work that you are to be doing on your own. Plan your work and time accordingly. AND MAKE SURE YOU BACK-UP YOUR PROGRAM FREQUENTLY TO AN EXTERNAL DEVICE SUCH AS A FLASH DRIVE OR YOUR OWN PERSONAL UTAD ACCOUNT.

Paper For Above instruction

The final exam project described involves comprehensive PLC programming using Siemens TIA Portal for the Ford FRAP facility. The project encompasses several critical components, including the configuration of input and output modules, the development of ladder logic to simulate tank level control, fire alarm response, and integration with Human-Machine Interface (HMI) systems. This essay discusses the detailed steps necessary to successfully design and implement these features, emphasizing best practices in ladder logic programming, system architecture, and HMI integration.

The initial focus involves setting up two Input Blocks for the internal levels of the North and South tanks, which measure water levels in feet. Logic must be developed to simulate water inflow into each tank based on these levels. Specifically, if the measured level drops below 22 feet, the system activates the corresponding solenoid valve to allow water to enter, increasing the level by 1 foot every 5 seconds until it reaches 28 feet. Once this level is achieved, the solenoid deactivates to prevent overflow. It is crucial that the ladder logic accurately reflects these conditions and prevents activation when the tank level exceeds 31 feet, which is the maximum capacity due to the external overflow tube. Developing modular code for one tank and replicating it for the other ensures consistency and efficiency, adhering to best practices in PLC programming.

The second part involves configuring an Input Block that simulates fire alarm conditions, where a user can input a value of 0 (normal), or 1 to 3, indicating the number of DWP (Distribution Water Pumps) that need to operate. When a fire condition is activated, both the North and South tank solenoids are automatically turned ON to ensure rapid replenishment of water supply for firefighting needs. The logic must automatically activate the appropriate number of DWP circuits based on the input value, integrating with the existing control system. Proper sequencing, safety interlocks, and manual overrides should be incorporated to reflect real-world operational requirements.

The project also involves reviewing and understanding HMI programming, specifically how to connect HMI I/O with the PLC, and updating the program to include HMI-based control and monitoring features. The HMI programming should allow operators to input tank levels and fire alarm states directly from the interface, providing real-time feedback and control capabilities. Familiarity with Chapter 7 of the relevant textbook and supplementary YouTube tutorials will assist in mastering HMI programming, which is essential for creating an intuitive user interface and robust control system.

Furthermore, proper configuration of the PLC I/O list, including allocation of the 14 inputs and 10 outputs as specified, is fundamental to ensure seamless interaction between hardware and software. The project emphasizes careful documentation, version control, and backup procedures, which are essential skills in industrial automation. Throughout the development process, iterative testing, validation, and troubleshooting are vital to finalize a reliable, self-contained control program aligned with industrial standards.
