It will also give the indication of major upstream and downstream processes and finally will provide visual indications of abnormal situations and alarms. • 2) Level 2 displays should include the information and controls that are required to perform most tasks on the particular process that was called from Level 1. Accessing Level 2 from Level 1 is a one-click operation. • The purpose of Level 2 is to provide a clear picture of the systems in the process selected from Level 1. • Once in Level 2, the operator now has the ability to operate process equipment such as pumps, valves, and compressors. • While it is important to follow the physical layout of the facility and the P ID, Level 2 screens should not look like a copy of the P ID. • 3) Moving on to a Level 3 display will provide detailed views and information from the Level 2 compressor display such as runtime, faults, alarms, commanded speed, and speed feedback. It could also include a custom trend showing process values such as pressure or flow. • A Level 3 display will also include detailed diagnostic displays and interlocks. Detailed Level 3 displays are intended for advanced control and troubleshooting, items that are not available on Level 1 or Level 2. Many Level 3 displays may be accessible from a Level 2 display. • 4) Level 4 Displays are obviously going to provide the greatest detail of sensors, subsystems, and individual components. In some cases, a Level 4 Display will provide information on PLC processor performance and the health of Input and Output channels. • This display is meant for extensive and advanced troubleshooting, interlock programming, and process setpoint adjustments. You will also be able to view operating procedures, alarm response instructions, and abnormal situation response guidance. • When possible, use a pop-up by utilizing a right mouse click on the alarm to provide a highly detailed and information-driven display that will give the operator clear instructions on the alarm and how to effectively troubleshoot it. • Some of the graphics and the HMI screens used in this video are from the High-Performance HMI handbook which is a great reference if you want to dig deeper into this topic: https://bit.ly/3bdWzkM • ============================= • What is High-Performance HMI? https://realpars.com/high-performance... • High-Performance HMI Design Basics https://realpars.com/hmi-design • Development of High-Performance HMI Philosophy https://realpars.com/hmi-philosophy • ============================= • Missed our most recent videos?
