You may have seen the news of the 2013 HART Plant of the Year noting: HART technology has helped reduce production downtime related to control valve failures… We use the HART signal to monitor real time valve conditions which has helped with identifying problems before they could cause unplanned events. This reliability effort combined with […]

Author: Craig Abbott Recently, a customer using a non-Emerson hand held communicator ran into problems during FAT. None of the devices they had configured would connect to the Rosemount 1420 gateway whilst other devices, configured by our technician using a 475 hand held communicator worked perfectly. WirelessHART, now recognised as the IEC62591 standard, supports interoperability, […]

Control systems provide signals to control valves to regulate their position per the requirements of the control strategy. It is good engineering practice, especially for critical control valves to have valve travel feedback from independent devices such as position transmitters, limit switches, or positioner output feedback. Emerson’s Riyaz Ali, whom you may recall from earlier […]

I wanted to bring visibility to several recent comments from an earlier post, Major Difference between Foundation Fieldbus and HART Protocols. Here’s the summation thought from the first comment: …With one software package, and as put above with HART pass-through, you can document EVERY HART instrument on site, and THEN with Plantweb, monitor the lot […]

I highlighted some of the challenges North American refiners face in an earlier post with tight oil from shale formations. Emerson’s Michelle Weimert has Hydrocarbon Processing article, Leverage diagnostics to keep production running smoothly, which looks at the role of temperature measurement diagnostics can play in reliable refinery operations. The article opens: The continuing trend […]
