Re: [foxboro] PIDA Foxboroese ???s

For that particular parameter, check out the PSS (product specification 
sheet) on the PIDA block.  It has some good info, some that isn't in the 
block description books.

I agree, though, that some of I/A's best features go un- or underutilized 
because of poor or lacking documentation, and no available training.  I 
have yet to use a PIDA to its full potential because I haven't had time to 
sit down and play with it to see how the advanced features (self- and 
adaptive tuning, mostly) behave, and that's the only way you are going to 
know.  There is no training class on it to my knowledge, and the docs do 
not go very deep into application examples.

[foxboro] PIDA Foxboroese ???s






We have been working on some PID and PIDA loops and the manual on these 
blocks are somewhat marginal. They use what we like to call "Foxboroese". 
Some of the Block descriptions are full of "Foxboroese", things that only 
apply to Foxboro systems, commonly opposites of other DCS systems (or they 
opposite of Foxboro) and cannot be Goggled or researched in any other way.

I would like to find some more info out on the interconnections on these 
blocks and how it is all tied together. Is there a manual or book out on 
these besides the Integrated Control Block Description Volumes? The one 
that comes to mind is SPLLAG. Is this tied to the set point as a gain 
before it gets to the loop or does the set point make it in and then it 
takes effect,  or may be something else ????

Thank You for Your Support
