View Full Version : Very interesting - what's possible with no EDDL?

I am running an old revision of DeltaV currently - 7.4.1 - but I was impressed with the transducer block capabilities available with one non-Emerson field device.

I am used to something like what's shown in the first attached jpg (http://forums.fieldbus.org/attachment.php?attachmentid=757&d=1169839454) for non-Emerson devices (a Flowserve positioner in this case) - the ubiquitous "Other" tab with a long scroll-down list of many curious / cryptic parameters. Enough to make you want FDT/DTM, I suppose.:rolleyes:

But the Metso positioner we installed earlier this month has more tabs, alerts, and diagnostics than even a Fisher DVC would show (Metso ND9000 jpeg's).

If Metso can do this, why not the other guys? Not quite the pretty graphics we're supposed to get with EDD's, but still a ton of information and many useful diagnostics (note drop-down on last screen-shot (http://forums.fieldbus.org/attachment.php?attachmentid=762&stc=1&d=1169840960)). Has this always been possible with DeltaV? I thought I'd have to wait for EDDL and some future revision of the DeltaV OS before the competitors' stuff looked this slick. Kudos to Austin and the Metso guys / gals for pulling this off, however it happened.

This makes the "freedom to choose" promise of FF that much more credible.

The other thing worth noting, all this information is stored and computed in the positioner itself & maintained there. There are fields for decades of historical diagnostics (note this valve has been in service about 3 weeks).

Thank you for taking the time to gather and post these screen shots. This powerful on-line valve diagnostic capability is unique to Foundation Fieldbus (FF) and unfortunately, it's been slow in catching on. This is what the future of instrumentation and control it is all about and it's only the tip of the iceberg. Such capabilities are limited only by the developers' imagination. More posts like this will help promote this exciting FF technology.
