Control a bath of hot water of RS - 232

Hello

I'm looking for suggestions on hot to control a water bath using a RS-232.  A week ago I want the computer communicates with the hot water bath, using an example called LabView "base read and write". Now, I want to set up an experience.  I want the bath of hot water to hit the following temperatures 30.50 and 30 again over a period of 3 hours.  30 c to 50 ° C temperature increase should be gradual and the reduction of 50 ° C to 30 C should be gradual.  What kind of code should I write this?

Where should I start? Any help is very appreciated!

Jack

Jack,

When you send 'SS030.00\r' unit, did you have the constant or the potentiometer '-' display Codes?  The chain controls and constants have several display modes.  Depending on the mode, what you see isn't necessarily what you get.

This string in a Normal display mode would end with the backslash character, and the 'r '. If the screen is in the ' \' Codes display mode, then he'd go to .

  • Gets VDR me in hot water - ridiculous restoration time

    My small business has spent a considerable amount of money on a VM/SAN solution and the power are pretty upset by the results we experienced last night.

    I have an older Windows 2003 vm that I converted from a physical server and its 'thick' disc is 67 GB.  Currently, VDR backups reside on a generic NAS with a single connection GB VDR connects to the NAS server via a windows on another server share as it's my only option to networked storage.  Farm of VMware is connected to EMC SAN via a dedicated 20 GB switch "fabric".

    The restoration of this virtual machine took 8 hours and management is not happy with the turn around time.

    I know that I gave very superficial details, but I could hear from someone who has performed a restore of a windows file share, and what was their performance?

    The design seems to suggest that data travels twice: once from the host vmware to windows box, then once in the windows for the CIFS share box.  is this true?  You can change this?

    67GB in 8 hours is 2.5 MB/s, pretty crappy flow.  You have studied the time it takes simply to copy the 67GB on the NAS part down to the Windows box in the middle and without doing a restore - just copy the file?  If it is 8 hours, then you have your culprit.  If you don't have the space in the windows box, then I would be by copying both NAS NAS share with the windows box in the middle. Again, if it takes 8 hours you have your culprit.

    Then I'd get a VM on this computer and copy 67 GB starting from this NAS share directly on it.

    Then copy 67 GB of the Windows box in the middle of the virtual machine.

    Get you my drift?  If you don't have room for 67GB, find something small you CAN go up and come and go every time.  See where is your slow link.

    Just curious: was this a test restore, or restore production which has never tested?

  • Documentation on a Labview VI

    Hello

    I'm doing some documentation/information on the VI I created. I created a VI that controls a bath of hot water by the use of a wave of fishing and watching the influx of Air mass flow controllers. I am about to leave my current job of laboratory (working in a University) and now have given the task of documenting the information available to me.

    I'm wondering now 'exactly' how much should I document.  The person who will end up using my code to continue and build off of it to automate some think more (lighting, pumps, etc.) will probably NO experience of labview.  Then... I have attached my VI and I was wondering how I can be more helpful to a new user of Labview (it doesn't have to be perfect, I just need to get my message).

    Questions/problems

    1. I can't describe what is happening in section 3. in labview yellow notes...

    2. I need to accomplish my task quickly... I'm leaving the country soon.

    Your help is highly appreciated

    Lydia

    P. S.

    I learned labview on mine and the schema is not the greatest. I believe that the next person will take a few parts and build off of it.

    You want to make the person understand the logic of the program?

    I mean, what function that task and etc?

    I've used flowcharts of the to do. To illustrate, use blocks of LV to show what is happening in the world.

    But your documentation is good, however. Just like the Bill, I don't have a background on what the application works, and I could understand it easily.

    Nice work.

  • Blocked ink jet

    My printer is a DeskJet 720C, and my colour, HP1823 cartridge, an unused original, which has been stored for a while and is now out of warranty, it's completely blocks Magenta inkjet.  The Cyan and yellow jets have also blocked when I tried first, but soon, they flowed and printed as usual after a few minutes in a bath of hot water and rubbing alcohol.

    A breath of air would help?  I could pull out the cartridge with me the next time one of my tires should be inflated!  Thank you!

    Blowing air from an air compressor would probably damage the print head.  You could try the print head to an inch of very hot water for a few minutes, but most likely you will just need a new cartridge #23.

  • strange appearance of the digital control

    Hello...

    I met a strange appearance of a digital control, see the below two screen captures.

    Reminder: on a tabpanel, two of several digital controls have been changed programmatically if I put an indicator with a checkbox that is located on another tab of the Panel:

    -control mode is switched / battery hot

    -precision went from 6 to 4 figures to compensate for the space of digital arrows

    These changes are applied to three checks, but only the first (highest) behaves unexpectedly, while others are very well...

    (A) if both attributes are changed, the two top controls look like this:

    in other words, the left most of the characters of the control are somehow overlapping, giving the impression of a fat o material

    (B) if only the command mode of the higher control is changed to hot, the following result is obtained:

    This makes it more obvious that somehow the two zeros on the left of the control are pressed together.

    Interesting, if I operate the higher control by clicking on the arrow/top down, the result displays (1.0000E - 3) is ok.

    I was much afraid to post this mystery which could well be a stupid mine mistake, but unable to locate a problem in the code, I thought that it could possibly be linked to the issue tab panel reported here

    Comments, suggestions?

    Thanks, Wolfgang

    Hi Wolfgang,.

    I checked your project, and it looks like a bug. I created a CAR. The number is 282946.

    I guess that at the moment, you have to live with it or place the box on the same tab.

    See you soon,.

    Hi, just given my wife a new laptop touch screen HP Envy 15 t.  She plugged the AC adapter to recharge the battery and the adapter got very hot.  Everyone knows this?  Is this normal?

    A hard, I guess. Mine feels just as warm as a cloth rinsed in the hot water and wrung out--but not as hot as a fresh cooked potato in the microwave. Yes, I'm not a gourmet cook.

  • My Officejet 4620 do not print black ink

    I replaced the black cartridge on my Officejet 4620 with a new high-capacity HP cartridge and it won't print black ink on the test page, any application or function of Copier.  I have reset the printer nothing helps.  The ink level indicates that it recognizes the new cartridge and says it's full.  Black ink out of the cartridge when I put my finger against the exit hole.  I cleaned and aligned the print heads, but still no go.

    just in case someone else has this problem, heres whats really past and heres how to fix this annoying problem. its relatively easy to do and more efficient than wasting money on a new printer or have that he repaired as most people eventually do.

    going on what? the ink has clogged print heads and solidifies closed. the function of "clean print heads" the printer comes with doesn't have the ability to solve this problem. This feature is to clean the heads Sales, not clogged heads. Why hp decided to make this model without a simple to remove the cradle is beyond me, but fortunately the cradle out and can be cleaned with hot water.

    theres a few items, you will need to get there easily, or you could just burst the branch loppers, like I did and vent your frustrations.

    you will need: a pair of slender beak pliers, a screwdriver torx T9 (selling auto parts stores them for a few dollars), paper towels and a space for work (its easier to do this in a corner of a room, on a small table or floor).  Keep in mind that you are dealing with ink, then change your clothes right just in case and also catch a paper plate or a few sheets of paper to print to set ink cartridges while you work.

    (1) ok. lets start. !!! FIRST UNPLUG THE PRINTER RIGHT NOW, IF YOU DO NOT ACCIDENTALLY DIE BY ELECTROCUTION!  I forgot and when I started unscrewing the first 6 screws, kept chime jump and im like * beep *? I was impressed by the security measures hp took as model engineering.

    (2) the printer is now disconnected and then go to your corner your work surface and place the printer, so there is a wall or a barrier on the left, and also, a wall or a fence behind it. This just in front of her as if you were about to use it.

    (3) now, what you have to do, is to open the printer as you will change the ink and on the right side, there is a plastic guide that prevents opening all the way to the top. Look on the side and you'll notice that he could jump off with fingers. pop off and open it completely open, so you can get to the screws of the cover you would have prevented access to.

    (4) press the scanner part and the upper part against the back wall.

    (5) all the screws you will be remove are the size T9H torx screws. There are ten total. There are 2 black screws in the top of the forehead and then 4 black screws in the top of the back. Remove them and put them on your paper plate.

    (6) following is 1 screw silver short located under the Control Panel, use your finger and feel under the * button. Unscrew, place it on the paper plate.

    (7) depending on whether you want to remove the face/Control Panel to get in the last 3 screws so locate the illustrations on the top of the printer, there are 2 on the lower left and 5 at the bottom right (1 and 2 on the left explain removals of paper jam and 1-5 on the right then explain change in ink cartridges). then about half an inch South of the illustration of the number 5 on the lip, is a plastic stand. six inches to the left is an another then 6 inches to the left, under the number of the illustration 2 (remove the paper jam) is a third support. Unscrew using your nails. Flip it up just like the hood of the car, and eten on the main top of the printer, keep the flat wire which is connected to the frame of the control panel (if the flat wire jumped because you got too loud, then simply insert it in when you go back).

    (8) then unscrew the 3 long silver screws that are located under the Panel you just popped off the coast. There is 1 on the left and 2 on the side rightish. mix 'em on the paper plate.

    (9) now that all the screws are removed, take the Panel front and partially pop it back together.

    (10) then take all over (the part with the small illustrations and lift like a hood of car, ONLY THIS TIME OPEN IT LEFT and he balanced on the edge of the printer, to lean over towards the wall or an obstacle on your left.) MAKE SURE NOT TO PULL ON THE STRIP OF COLORFUL SON FRUITS LEFT AND ALSO THE FLAT BLACK WIRE CONNECTING PART SCANNING FOR THE MAIN OF THE PRINTER PART.

    (11) then take the pliers to tapered spout and remove the 2 silver tension springs located behind the printer cartridges. Pay attention to where they were attached so you remember where they go during the Assembly. take a picture with your phone if you have to, or simply re - understand it like I did. mix 'em on the paper plate.

    (12) then disconnect the 2 large flat wire and 1 small flatwire attached to the back of the ink cart. take a picture or can remember like I did. I guess bad things can happen if you reverse the on re-Assembly. Pick up the phone and take a picture of quik to be sure.

    (13) now remove the cart ink, cartridges and all, by lifting the front first.  Be careful of the transparent tape little there that moves the carriage from left to right and vice versa. you don't want to damage this little guy. now take the transport to your paper plate. not some ink or accidentally get it on your fingers without knowing or will make a mess.

    (14) remove the ink cartridges and put them on the paper plate, side ink to avoid a mess, these things sometimes drip. put the plate side. its time to clean the print heads.

    (15) then go to the sink, to the distribution of empty ink and turn on the hot water and then let the transport of empty ink sitting there with the water mainly through the clogged color screen (inspect and make you is not a small rubber seal surrounding the small screen, if there is do not waste it. I didn't look too closely and I don't think that hp has them but I have a few other printers). It will stain the sink but water ink he comes out to be sure. notice there is also a small circuit attached to it. don't bang it upward but getting wet does not matter.

    (16) continue to do this until the water is clear.

    (17) then use your finger and rub the screen gently with your finger and then rinse it, taking ink until the water is clear. This continues until there is no more ink and screens are clean. do it for all the colors just for good measures. the color of problem that would not print, you'll notice takes longer to clean than the other colors.

    (18) now look on the lower side of the transport. these strange looking things are the leaders. Rinse in hot water and dry them with paper towels. then flip it over and the breath on the side of the screen again. also between the screenside and heads (on the side of the transport) is an opening which is also probably gunked up. It blows with water too. Then, turn it over and wipe the head again. Repeat this step until no fades or until you are sick and tired.

    (19) shake, then use paper towels to dry the entire unit. Make sure that the device is dry.  especially inside the female plugs. blow inside or out dry hair and dry gently. do not stand there and melt the but with the blow dryer. but the sooner it dries less your ink cartridges, sitting on the paper plate will dry out. the custom of the ink dry quickly just do not take a NAP or go on a date until you're back with part of the ink.

    (20) now you have finished cleaning the heads and probably don't need to do it again for the length of time, it was because you bought the printer. and just as a roadtrip you used a map to navigate, you will use these instructions in reverse for reassembly. but keep in mind when re - insert the 3 flatwires that you disconnected from the back of the ink cart, make sure you that have small metal contact on the flatwires points (side male) inserted so they affect small metal contact points on the caps of transport (feminine) side. ALSO BE VERY CAREFUL NOT TO DAMAGE BLACK FLATWIRE CONNECTING THE SCANNER PART PART HAND PRINTER. THERE IS A SMALL GROOVE IN THE PLASTIC WHERE IT CAN SIT TO GUARANTEE NO CRIMPAGE. USE IT. also make sure that the 2 hinges to the scanner portion/cover are placed correctly before the fixing of the top with the 6 black screws.

    now raise the printer and reinstall the ink cartridges. then plug in the appliance and turn it on.  If you get notifications on the control panel telling the custom of transport move, then open the trunk and remove the ink cartridges, hustles and ensure that transport is installed and that the tensioner springs are in place correctly. Repeat the operation if necessary until notifications go away or just do a test print and do not take into account the notification if you messed with it a few times already. That's what happened to me and the notification went his own. Once its online, open the hp utility and press the button "clean the heads. do 2 x in a row and you will be in style, with colors extremely rich and "BOLD" and Yes, printed black raven.

    p. s.

    You can always take your aggression out with tree limb loppers or Tin shears like I did and cut the plastic Center keeps you to transport directly outside. Completely eliminates the disassembly and reassembly. Make sure you DO NOT CUT THE TRANSPARENT TAPE THAT MOVES BACK AND FORTH TRANSPORT. This way the next time it happens it takes you only 10 minutes before you are upward and printing.

    Enjoy!  -Porf

  • "prints" but the page is empty

    My hp officejet 6110xi all-in-one that seems to work fine, but after the 'printing' the page comes out blank. I tried a hard reboot and have gone online to make a diagnosis of HP print - the diagnosis has not detected a problem, but when I printed the test page, it was empty.  Any ideas appreciated!  Thank you

    Probably your cartridges have dried, perhaps due to power the printer before removing the cartridges were lucky to the Park.  Try to run the three cleaning cycles to the Toolbox, as described here , then try to print a page of test, as described in this page.   If there is any suspicion of printing (even a few strands) then the electronics is OK.  In this case a more thorough cleaning cycles can help.  If this isn't the case, then soak the print head in about 1 "of very hot water for 10 minutes or if can wipe the nozzles.

    If there is still no sign of printing, this may indicate a power failure of the electronic control unit of printer.  You can check the cartridges dabbing them on a damp cloth.  A good cartridge will leave a dark spot of cyan, magenta and yellow or black according to the cartridge.

  • How to get a signal triggered by TIMER (under Board user) using GetUserEvent() event

    Hello

    I want to use GetUserEvent() inside a loop for the TIMER event, rather than use the calllback RunUserInterface() and TIMER to vote.

    but it seems that GetUserEvent() can not get the TIMER event. Is there something I should note before using GetUserEvent()?

    I use a button (PANEL_Add) switch TIMER ON / OFF, the time interval is 1 second and TIMER is initially DISABLED.

    PANEL_LED indicates the State of the TIMER POWER indicator.

    Hello

    According to aid GetUserEvent Gets the next validation event or an event defined by the programmer of the GetUserEvent queue. A validation event occurs when the user changes the State of a hot water or validate controls or selects a menu item.

    Place the events defined by the programmer in the GetUserEvent queue by calling QueueUserEvent.

    Because the timer does not generate a validation event, you must call QueueUserEvent; to do this, you will need to use the TimerCallback function that you don't like... I see no other way than to use the timer callback function

  • All-in-one HP Photosmart C309a "Alignment failed" error message even after cleaning the print heads, etc.

    About 3 weeks ago before making the error msg above, a large black ink blob appeared on my printed piece of paper.  This product for several sheets later, but kept decreasing in amount.  I continued to print & finally all traces of ink have disappeared.  2 days ago I got a msg of error on "load plain white paper. ", but the paper tray was plain white paper in it.  I have removed the paper, straightened and her successor. As a result, the msg "Alignment failed" appeared.  I went through all the steps HP online information on the treatment of the "alignment failed", including the cleaning of the printheads (the right amount of ink was on it), check the vents of cartridge, etc.  My question is: if I have 4 out of colored inks and a new black ink installed, the alignment is being affected by the old cartridges?  A msg on this appeared on the Control Panel, giving the opportunity to proceed with the old cartridges or install new ones, but be careful that it "cannot allow completion of...» "If 'old' were replaced not.  I need to replace these color cartridges or is it probably another problem, which is print head damaged?

    Checked the evacuation & there is no problem, so I tried the informal solution to put the printhead in hot water.  A ran 1 cleaning via / configuration on the printer and finally aligned with success tools.  I waited a while to respond because I wanted to see if the printer should continue to work, and there!

    Thank you very much.  I'm happy that I can keep this printer!

  • IP 7220 alignment problem

    I'm running with windows and an ip7220 printer.  This printer was sent, by cannon, 2 years ago (part of which is quoted below - last paragraph), as a replacement for another printer Canon (ip4920) that had gone wrong.  This printer don't work never really at the height but, now its going to be replaced.  The problem is quite simple.  When you print the thing checkprinthead the top black vertical lines are not strong but are two teeny black lines.  This effects all feel so photo eventually stained.

    I took the print head and cleaned nothing doesn't.  I cleaned it by washing it and then put it in a bath ultrasonic until the cleaner media (hot water) ran clear.  This is usually the case but, in this case, it made absolutely no difference and nothing has changed.   I ran all programs maintenance several times without success.  This thing will be all simply do not align properly and the black parts of the alignment process are all stained and never reach any type of solution regardless of the parameters bar none.

    (Mod Note: serial number removed as directed by forum), has been shipped via UPS. This is a replacement for your Canon  (Mod Note: serial number deleted according to the forum).

    Thoughts?

    I did everything I could, but just simply omitted.    I bought another printer that continue.   Thanks for the reply!
