QUOTE(mross @ Feb 28 2007, 01:39 AM) I hear ya! Come to think of it, most of my rants are usually written late at night when I probably should just give up and go to bed For what it's worth, I also thought it a bit odd that someone with LabVIEW wouldn't know to contact National Instruments about upgrading, but I figure that he's/she's new to the game and perhaps had the older version handed to them with little exposure to the community at large.

QUOTE(Jeff Plotzke @ Feb 27 2007, 01:24 PM) Shelia! QUOTE(French LVer @ Feb 27 2007, 10:45 PM) Regulation chosen is based on these two facts : - setting point changes slowly, - and controlled system is quite stable. So i use a loose proportional regulation loop (no I and D) for coarse valve. And fine-tune valve do all regulation job (with mainly integral). That is indeed a valid control molel :thumbup: , but I don't completely agree with the first of your two "facts": it should work irrespective of the speed of the SP - it's actually the speed of the response of the system to the P control.

QUOTE(mross @ Feb 27 2007, 04:41 PM) Personally, I think you are - I don't see anything in siallid's original post that suggests that he/she is looking for a bootleg copy. I also interested (from a human perception standpoint) why did you assumed that his/her intent was a dishonest one?

QUOTE(Michael_Aivaliotis @ Feb 27 2007, 09:40 AM) You're absolutely right - I noticed that once I'd submitted my blog entry - thanks!

QUOTE(Jeff Plotzke @ Feb 27 2007, 11:54 AM) Indeed!

QUOTE(Jeff Plotzke @ Feb 27 2007, 11:40 AM) Actually, if your fine setpoint is good at 10% and you know how much 10% of your fine is in relation coarse, then once you've reached your setpoint, you can slowly (relatively speaking ) start bringing your fine back to 50% while adjusting your coarse to compensate - then, if your input changes a little, you're in the best place to be able to adjust for it. QUOTE(Jeff Plotzke @ Feb 27 2007, 11:40 AM) So, while writing this, perhaps it makes since to have it switch when it's a certain delta away from the setpoint... Sounds like you've just had a What you're describing is a simple fuzzy loic system. Oh, and yes, that's indeed a great idea - you could also consider it in the time domain: use your coarse to get it to a "close-enough" value and then switch over to fine - this is certainly different to the process you've already suggested, and it very-much dependson the system that you're working on. Personally, I'd steer away from temporal control and stick with the relative control. QUOTE(PaulG. @ Feb 27 2007, 11:30 AM) Does this have anything to do with "DP"? "DP"?

Your reasoning looks sane for the most part, but AFAICT, your biggest issue is going to be when switching from fine to coarse: you said: QUOTE Depending on your physical phenomena, that may not be a good idea: imagine if you did this when your fine is at one of the extremes (say, below 10% and above 90%) - you're saying that you want to swing that to 50% - that might not be a good idea and could cause a big change, and maybe even an instability in your system. Your best bet is to know how coarse and fine are relative with respect to each other - ie: fine full scale will be representative to a percentage of the full scale of the coarse: then, when you do swing the fine back to 50% you should simultaneously adjust the coarse to compensate for the instability. For example, if your fine full scale represents 10% of your coarse full scale - if your fine is at 20% and then you want to swing it to 50% without making a change to the output, you'll need to swing your coarse down 30% of 10% (around 3.3%). I'm not 100% that I've been 100% clear - give me a yell if you need me to clear it up. Once you've got the concept down it shouldn't be too difficult to set it up - it's just the relativity that you need to work out.

When I upload an image into a blog entry and then try to insert it inline, it pastes the following text into my blog entry: http://forums.lavag.org/index.php?act=attach&type=post&id=5041 That looks right, but when I preview the blog entry, the image doesn't make it - the text remains. I've done this successfully before (last time was on the 1st of Feb).

QUOTE(GregSands @ Feb 27 2007, 07:41 AM) G'Day Greg - what version of LabVIEW/Vision did you upgrade from?

Has anyone got any other UML tools to add to the list?

I just did a search for "UML" and got nothing :thumbdown: I then tried "UML*" and got some hits, so I figure I'd add a post here - I did a search for "+search +sucks" and, you guessed it, no results! I finally found this post after searchinf for only "+sucks"

QUOTE(chrisdavis @ Feb 23 2007, 01:42 PM) I (of course) use the VISTA Help Documentation Generator - it's probably the VISTA tool that I use the most. It creates HTML files and/or Compiled HTML Files (that's those neat chm files that form Windows-style help files) from some user-definable fields including name, icon, VI desctiption, etc. Here's an example of a Compiled HTML File that I just created from The Captain's Tree Control API LAVAcr submission: Download File:post-181-1172203925.zip Also, you can get a demo copy of the tool - PM me directly if you're interested in trying it out.

QUOTE(Dave Graybeal @ Feb 23 2007, 06:17 AM) :thumbup: Nicely done! QUOTE(Michael_Aivaliotis @ Feb 23 2007, 06:17 AM) Typedefs or NOT, this is not normal. I agree - let NI know that you've found a bug.

Firstly, you're missing these controls (I just disconnected them from the typedefs): EOS detect.ctl Setup data.ctl DAQ tasks.ctl Tescom.ctl Piston.ctl Aux input params element.ctl Aux input params.ctl Initialization_misc data.ctl Pulse paramteres.ctl Secondly, it's not the USR that's the issue - probing after the constant in the init case never gets written too. Something very odd is going on here - if you remove an element from the cluster constant (just drag something out) then probe the wire as it comes out of the constant, then run the VI -> the probe closes...
