Where is the value for the customer? • Detailed device performance and status information. Customers are asking device vendors to implement more predictive type algorithms in the field device. • On-line configuration tweaking (i.e. damping and range) • Absolute (not inferred) information about each device. • Reduced time in startup and commission phases. • Remote HART device configuration and setup. • Remote HART device configuration verification. • Quick and validated re-configuration for turn around and product changes. • Reduced cost in wiring with access to secondary variable information. 15 HONEYWELL 15 September 19, 2012
