Please checkout the overview before getting started. You can also view Deminar recordings to see how the labs were used to explore various opportunities to utilize the power of the PID to eliminate oscillations.
- On the main lab operator graphic screen, click on the lab of interest.
- To access the data historian, click on the “trend chart” icon next to the faceplate icon (if the trend chart for your lab is not visible, click on the “open folder” icon on window tool bar and select the trend chart with your lab in its name).
- To access a PID faceplate, click on the “faceplate” icon.
- To access the PID limits and tuning parameters, click on the ‘Detail” icon on the bottom left corner of the PID faceplate.
- To access and change the details of the loop lab dynamics, click on any block in the block diagram. For the unit operation labs (temperature and pH labs), click on the “Temperature Control” and the “pH Control” buttons to access to the details of measurement, disturbance, and control valve dynamics. The process dynamics for these unit operation labs are presently set internally based on equipment size, flow rates, and process info.
- In the upper right corner of the lab graphic, you can change the lab mode by clicking on the current lab mode to the right of “101 Run, Explore, or Test.” In the “Explore” mode, the user is free to change any dynamic details to create a case and make setpoint and load disturbances. In the “Test” and “Run” modes, the case dynamics are frozen and automatic disturbances are injected that were set up in the “Explore” mode. In the “Run” mode performance metrics are generated. At the end of the run (set by the “102 Run and Test Time (sec)”), the run results are saved as the “Last …” metrics. The best results are saved as the ‘Best …” metrics.
- To go back to the main graphic screen to select another lab, click on the “back arrow” icon to the right of the “open folder” icon on the Window toolbar.
