Question 4 Many modern distributed control systems (DCS) also host software to allow communication with HARTenabled instruments. One example of such software is Emerson’s AMS: What does this particular screenshot reveal about the HART-enabled instruments connected to this Emerson DeltaV DCS? What advantages do you think might be realized by having the DCS be able to digitally communicate with field instruments? What disadvantages can you see to this method of HART interface, as opposed to a hand-held HART communicator? 24
Suggestions for Socratic discussion • With the DCS enabled to “talk” HART with field instruments, one cannot also use a handheld HART communicator to “talk” with the same field instruments. Explain why. file i00665 Question 5 Read and outline the “Introduction to Pseudocode” subsection of the “Digital PID Algorithms” section of the “Closed-Loop Control” chapter in your Lessons In Industrial Instrumentation textbook. Note the page numbers where important illustrations, photographs, equations, tables, and other relevant details are found. Prepare to thoughtfully discuss with your instructor and classmates the concepts and examples explored in this reading. Feel free to skip past the portions of this subsection discussing branching and functions. file i02920 25
