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 […]

The Fieldbus Foundation has an active LinkedIn group where users of this digital bus communications technology share expertise. I saw a recent question [hyperlink added]: i came across a document which mentioned that in reality IEC 61158 specified cable is actually not required. They may bring installation benefits, but is not required. Emerson’s Dan Daugherty, […]

I caught up with Emerson’s Dan Daugherty, whom you may recall from earlier digital bus and wireless-related posts. Dan has been focusing his efforts on WirelessHART project implementation practices over the past year. Much like the introduction of various fieldbuses led to the need for design guidelines to better incorporate these technologies into automation projects, […]

John Rezabek closes his Surprise! Field-Based Control Beats DCS article with the thought: The SP50 committee set out years ago to define and specify a robust, vendor-independent controls suite exploiting the intelligence of microprocessor-based field devices that would equal or exceed the “bulletproof” DCSs of the 90s. They succeeded. The source of this conclusion […]

On the Fieldbus Foundation Forums is a recent post, Macrocycle for control in the controller. The post begins: I have seen many posts about scheduling and macrocycle calculation for control-in-the-field (CIF). I have some doubts about control-in-the-controller (CIC) application. Unfortunately, there is no other option in the project I am working for. The question asks […]
