Hi Jack, Combination of both would be nice, we have Foxray, which is a great help in analyzing alarms, but we also need a shelving tool so our operators can "park" troublesome alarms for a while (under certain conditions and with supervisor approval). So I'm also interested in the shelving tool experiances and alternatives. No idea on the price of the Foxboro shelving tool, probably only affordable for the big guys as usual? Kind regards Dirk I agree Foxboro's Alarm Shelving Tool would be extremely useful at most sites. During initial Foxboro installation, most systems have nearly every alarm (to include status) possible turned on and they usually stay that way unless considerable man-time is put into taming them down or making them smarter. Although I have no experience with the Alarm Shelving Tool, I can see that it would tremendously help tame down alarms and actually make them much more useful and reliable. However, Alarm Shelving Tool (like most things useful) isn't cheap and requires a lot of Foxboro and local site man-power time to implement. FoxRay isn't exactly free either, but I don't think it is as expensive as the Alarm Shelving Tool when all factors are considered (especially man-hours to achieve usefulness). My recommendation of FoxRay (a different product from Alarm Shelving entirely) is due to the fact it is more immediately useful for all kinds of Foxboro data to be used by local Engineers/Technic ians to improve their systems to include alarm monitoring somewhat. The main point is that the Foxboro Alarm Shelving Tool is primarily focused on reducing alarms and making them more useful, whereas FoxRay is all about collecting and historizing all kinds of Foxboro data. Both are great products with different functions. _______________________________________________________________________ This mailing list is neither sponsored nor endorsed by Invensys Process Systems (formerly The Foxboro Company).
