New Paper on Endress+Hauser Approach to Fieldbus Diagnostics
FOUNDATION fieldbus has a unique approach to management of device diagnostics. The publish/subscribe structure of FOUNDATION fieldbus means that diagnostic information is available immediately to a wide range of workers in the plant. The challenge is to organize that data in a way that turns it into useful information for the right people at the right time. That’s why the Fieldbus Foundation created the Fieldbus Diagnostic Profile addition to our specification. The Field Diagnostic Profile incorporates the NAMUR NE 107 recommendations, which state the diagnostic data should be presented in a standard manner, with standard coloring and symbology, so it is easily understandable by the different worker roles that must have access to the information.
As with all our technology specifications, Fieldbus Foundation provides a standard framework on how data should be handled and provided to those that need it. The suppliers in turn have the ability to add their own competitive advantage by providing ways to manage an even wider range of diagnostic information within our standard structure. This is what Endress+Hauser have done with their approach to FOUNDATION fieldbus standard diagnostics, and they are making this approach available to other automation suppliers as well.
Endress+Hauser is one of the world’s leading process automation suppliers. The company was one of the founding members of the Fieldbus Foundation, and has a long history of involvement standards making bodies and committees. The company’s new approach to categorizing fieldbus diagnostics has value not just because it can provide a wide range of diagnostic information about its devices, from electronics to sensing element to the process itself. The Endress+Hauser approach also gives the company the ability to form new diagnostic models based on the information from and relationships between multiple devices in the plant. This brings the diagnostic capability to the asset, unit, and plant level. Endress+Hauser also wants to make this diagnostic capability available to other vendors. Read the rest at the link:
