• Why is the HI bus speed 3 I .25kbps, not something different, suitable for closed loop digital control?
• Is the digital signal in FF susceptible to noise? If so, how can it be reduced?
• Can you reuse the 4-20 mA wiring of an existing plant? What is/are the criteria?
• What kind of redundancy is possible for fieldbus system?
• Can separately-powered and bus-powered devices be mixed on the same segment of an HI bus in an Intrinsically Safe (IS) system?
• What is the difference between a sensor bus and a fieldbus? Can control instruments (transmitter or control valve) be placed on a sensor bus?
• What is the point of removing several layers of the OSI 7-layer system to make it simplified for FE?
• How can a fieldbus system be implemented in an existing HART system?
• How can multiple variables be measured using a single fieldbus instrument?
