PWM Actuator control and monitoring

Hi,
I am working on a personnal project and I need to control three (or maybe 4) linear actuators (fyi, dyadic SCN6 (uncertain as of now if i'll be using SCN6-020/040 or 060, but they are pretty much the same). (Spec Sheet: http://www.miraiintertech.com/home/downloads/Dyadic1003.pdf )
I do have some LabView skills, but i do lack some electronic skills to determine how to have LabView control those actuators.
I have a LabView Vi that i want to use to send some (help me here) PWM signals to control the actuators... I might need to monitor them as well to have a better control.
So my question as of now is, what do i need to do that, what kind of PWM controller/card (I don't have a clue), and can you provide me some knowledge regarding this technology.
Thank you very much,
Marc

Thanks for the reply,
After looking around, I might have to do it differently than i first expected.
I will use LabView to send position orders to the SCN6 actuators. From what i heard, I think i'll have to use some LabView compatible card with (analog) outputs, that then will then connect to somekind of servo-motor that then will be able to drive the actuators' motor according to my LabView's instructions...
PS: I said analog, because the guy i talked to said it might be better for me to send analog signals than doing PWM and sending the bit to change the direction
I really need help here, as you can see !

Create Remote Control and Monitor VI

Hi all,
I have 2 VIs. One is PC Host VI and other is cFP2200 real-time running VI.
Now I can use PC host and cFP shared variable to control and monitor in the same network.
But I have a problem that I need 2 or more cFP in the same network.How can I seprate to control themone by one?
They are using the same program but set with different IP.
Does shared variables are using fix IP and can I type the cFP2000 network IP in PC Host VI to select different cFP?
How to do ?
Thanks.
Robert

Hello Robert,
You will need to use a separate shared variable for each cFP. You can create a Case Structure in your Host VI to select which shared variable to use based on which cFP you select. I think that's the simplest option for you.
There is also a way to programmatically change the data binding for a shared variable, but this requires the DSC Module. Take a look at this article if you want to check out this option: http://digital.ni.com/public.nsf/allkb/2E8BAD0EA218A7558625712E0003F044?OpenDocument

Web application, control and monitoring

Good moorning!
I'm developping a web application, to control and monitor several instruments, Fieldpoint and GPIB. I haven't found any problems yet (I'm not asking for help ), but I'd like to hear your experience in this field. I've just created a website (an ugly website, I recognize). And I'm learning how to open front panels on the web, and changing from one to another.
Do you have active websites with visible front panels from the web? Do they have public access?
Thank you in advance!

Control and monitoring of traffic lights

i am a student and new to graphical programming.i am using labview 6.1 to monitor and control a system of traffic lights from a central location.my problem is geting the lights to go on and off.

You asked the same question here and the answer is still the same. Provide some details on what exactly you're attempting to do and what specifically is the problem. That means details on what kind of hardware you're using to interface to the lights, any error codes being generated, etc. Posting your program would help as well.

Camera control and Monitor Software

Hi All,
Two questions, quasi-related.
First, does anyone know of any camera control software for Sony? I have a TR27 and an HDR FX1.
Second, does anyone have any experience with monitoring software? Specifically, I am looking at the Red Lightning DV Monitor software. It would be nice to go from the camera directly to the hard drive. Also, is there any software which lets you monitor more than one camera simultaneously?
Thanks. Any input/links would be helpful and appreciated.

They should produce the same EXACT version of the RAW file.
The profiles are meant to give approximately the same rendering concerning tone and color. You cannot render the exact same thing as Canon uses proprietary algorithms which Lightroom cannot use. The profiles just approximate those using Lightroom's RAW engine. Also they will only come close if you use default settings in your camera, so no highlight priority, no added saturation, etc. If you want the exact same thing, shoot jpeg or convert the RAW to tiff in DPP. That said, my experience is that the camera matching profiles come very close to out-of-camera rendering as long as you don't modify the styles.
I say they HAVE to, because otherwise who is right - who´s got the true colors (e.g. Faithful style is supposed to represent colors exactly if shot at 5200K, yet DPP Faithful differs from LR faithful????)
None of Canon's styles give accurate rendering. That is not what they are meant to do. They are meant to be visually attractive, which is very different from accurate. Faithful is not really scene referred correct color. See for some measurements of that on one of the more accurate cameras, the Canon 5D mk II, here. The way to get correct color, if that is what you are interested in, is to shoot a colorchecker chart and use Adobe's free DNG profile editor to generate a calibrated profile for your camera.
Also, is there a way to convert other picture styles one has created into Lightroom profiles perhaps through some use of DNG Profile Editor?
No. Would be neat, but is not currently possible without a lot of manual labor. You can shoot a colorchecker and by comparing the rendering in DNG profile editor to that in DPP visually and using the patch tools, you might be able to sort of get there but that is going to be very tedious. It would be nice if we were able to give DNG Profile Editor a different target than perfect rendering of the colorchecker, because right now, the only way to do it is visual.

Temperature control and monitoring?

I've been tempted to start some gaming on my mac pro, from what I've read so far, OS X SL doesn't have anything to monitor the temperature of GPU, nor does it have anything like catalyst to tune up the fan speed when needed as the GPU heats up.
I read about smcFanControl, does it work on a mac pro 5.1 running 64 bit kernel? If i decided to do some 3D gaming for games like COD or WoW, what sort of fan speed would I need to make sure that the GPU doesn't get fried?
If I were to game on boot camp windows 7, which drivers should I install beside the default bootcamp driver that comes with the SL installation DVD? I noticed there is a catalyst driver package specifically for mac boot camp, am I limited to this driver package or can I install the latest ATI catalyst driver package that are normally available for windows?
Anyone have any experience with gaming on a mac pro 5.1 with dual ati 5770 video card? Any tips would be great.
Appreciate for your help.

smcFanControl will run on a 5,1.
There's the free iStat Pro widget which give limited temperature info.
There the shareware iStat Menus which does give info (temps, sppeds, voltage, amps, power) for just about anything it can get at. One piece of info is the PCIe slot temp for the slot the video card is plugged into. It also has some fan speed controls as well.

Thing is i dont know how to enable CPU fan control/regulation ifd possible. Doesn't realy see anything anything in the mobo manual except mentioning AMD Cool’n’Quiet.
This fan i have installed is running fine but i thk it runs full speed all the time and that makes a lot of noise - not needed.
Thx for any advice/tip/hint

40 °C is fine. The minimum fan speed can be set is a % of the full capacity.
Start with 12.5% and if the fan needs to adjusts it's fan speed too often and it get's annoying you can raise it to 25% or more.

Grid Control and SOA suite monitoring best practice

Hi there,
I’m trying to monitor a SOA implementation on Grid Control.
Are there some best practices about it?
Thanks,
Nisti
Edited by: rnisti on 12-Nov-2009 9:34 AM

If they use it to access and monitor the database without making any other changes, then it should be fine. But if they start scheduling stuff like oradba mentioned above, then that is where they will clash.
You do not want a situation where different jobs are running on the same database from different setups by different team (cron, dbcontrol, dbms_job, grid control).
Just remember their will be aditional resource usage on the database/server to have both running and the Grid Control Repository cannot be in the same database as the db console repository.

Accelerometer sense tilt then interface with USB-6008 and generate PWM to control M995 servo motor

hi everyone,
currently im doing a final year project in LabVIEW using USB6008. my project involve of sensing the tilt from accelerometer and convert the tilt into PWM to control the turning of servo motor.
accelerometer that im using is ADXL322 which has Dual axis ±2g sense range
servo motor that im using is M995. when the servo motor in neutral position it required 1500microseconds, while it turns 90degree it requires 2200microseconds and whilw it turns -90degree, it requires 800 microseconds.
currently im facing problem in generating the PWM signal to control the operation of servo motor.
attachment is my VI design that i have done to date.
the program is about attracting tilt range from accelerometer using USB NI 6008 and then convert the tilt into angle in degree, and after that generate PWM to control two servo motor.
hopefully there is somebody can help me on this. thanks.

Is there a way of connecting the ipad to the smart board in the classroom, so that the smartboard is the control, and the ipad is displaying what is on the smartboard? This is to help a visually impaired child see what is on the smartboard.,

Is there a way of connecting the ipad to the smart board in the classroom, so that the smartboard is the control, and the ipad is displaying what is on the smartboard? This is to help a visually impaired child see what is on the smartboard.

Absolutely!
Install Splashtop2 on the PC and enable it to be controlled or ran from iPad or Reflection to simply allow iPad to serve as PC unwired monitor. With Splashtop and an Apple TV connected, you use the smartboard as usual, yet the PC and iPad can see the same content. The impaired child can even interact with the Smart Board via the iPad as if he were writing directly on the big screen. Erasing functions can be done by touching the Smart Board manual controls. Several variables are in play that cause this lack of functionality:
    Apple won't permit PC software that infringes its proprietary apps.
    Smart Board companies refuse to develop iPad apps because they feel threatened and are being replaced by iPads
    School districts think Apple TV is meant for copyright infringement and could expose them to safe harbor lawsuits
    Network administrators make it impossible to login Apple TVs because they don't want the streaming occurring
    Classrooms are not able to keep up with the technology of using the iPad
    Clicker companies refuse to play with iPad because they see it as a potential threat to their core business clients
    Apple is not working as hard as it could to exploit its capabilities in education, thus losing money in iPad sales
The bottom line is that we educators and technology developers are hurting our childern with petty conflicts.

How to give browse and monitor only options of an ICM script to a certain group?

I am looking for an option in the Feature Control Set, how to give "Browse and Monitor" only options for a certain group in our contact centre. If someone give me some clue, it would be appreciatable.

Hello Praveen,
This work at some point. But it's not resolving what I intend to do. When I give "Read Only" previledge, to the certain group, it won't be able to do other tasks what they do day to day. I am looking specifically to give read only previledge in the scripting level. Not at the configuration level.
Thanks.

Show separate documents on laptop screen and monitor

I just set up my new monitor and the screen is identical to the screen on my laptop. I purchased the monitor so that I could work with two separate documents at the same time--one on my laptop screen and the other on the monitor. How do I set this up.

R1200GS, welcome to the forum.
Since I don't know which OS you are using, I have given you the instructions for Win 7. I believe all you have to do is open the two documents that you want to view and move one of them to the other monitor. If the second monitor is on the right side (facing the screen), move the document to the right side and it should show on the second monitor. You will have to set this up in the Control Panel / Display / Change display settings. You should see Monitor 1 and Monitor 2. If you don't know which is 1 and which is 2, simply right click on one of them and select "Identify". This will momentarily show the numbers on the screen of the monitors.

Figures in Grid Control and Enterprise Manager Console don't match!

Hi,
I have just installed Oracle 10g Grid Control and it is managing an existing database on another server. It appears to gather information as expected in most areas (I can look at the alert log through grid control and it is up to date to the nearest 60 seconds as I expect) but today I looked at how full my undo tablespace is and the figures seemed completely wrong. When looking through grid control it showed me that Undo was 20% full. When I looked in the old java console, it showed it was 30% full!
Is there any reason why figures in Grid Control would not be accurate or up to date? I have no error messages and it seems to be gathering data fine.
Is it more likely the old java console is not accurate? (I've always found it accurate in the past I think!).
These are Solaris Sparc servers, Oracle 10.2.0.3 Grid Control monitoring an Oracle 10.2.0.3 database on a remote server via management agent.
Thanks,
Paula

And this morning my old console says 21%, and the new Grid Control says 14%. So they both seem to be gathering the info and putting it out but they have completely different opinions on how much space is used. I think that makes the whole thing fairly useless. Not so glad I spent an age trying to get grid control set up now!!!
Any thoughts much appreciated!!!!
Thanks,
Paula

Hardware config and componenets : raid, gpu and monitor choices

Right,
I've almost finalised my decisions about a new build I'm putting together to use cs4 design premium prgrammes (mainly photoshop, InDesign, Illustrator, fireworks and flash) and in the near future 3d Max and possibly a video editing programme.
There are some things I'm stuck with for now; Motherboard and cpu, and some things I have a few questions about: raid 0, gpu and monitor choices. I appreciate this is a long post - but any feed-back would be appreciated.
MOTHERBOARD AND CPU
The motherboard and cpu were originally intended for a gaming pc:
MSI DKA790GX Platinum Motherboard
AMD phenom x4 9950 black edition
This motherboard and cpu are far better than any other I've had at my disposal when it has come to working with adobe programmes (CS2). So although
- I will only be able to go up to 8gb of ddr2 800mhtz ram (apparently the motherbioard becomes unstable with 8 gb 1066 ddr2)
- I do not have a motherboard that takes 2 6+ core cpus
From what I've seen of reviews on these components, at the moment, I'm quite happy with what I've got for both cs4 and 3d max use.
Besides, in the last few weeks I've learnt there are other things I can do to get maximum leverage out of a build comprising these components.
HDD CHOICE FOR RAID 0
I've read Harms generic guideline for disk setup here
http://forums.adobe.com/thread/662972?start=0&tstart=0
I gather that this guide is principally for optimum running when video editing. But I also gather that the performance enhancement of raid 0 compared to no raid will be beneficial for both photoshop and 3d Max. 4 discs with 2 in raid is what I was thinking of going for.
Discs I have or am thinking of buying:
1. I have 1 160gb WD ide 8mb cache hdd WD1600AAJB
2. I have 1 500gb WD Caviar blue SATA 16 mb cache hdd (WD500AAKS)
3. For the raid I'm thinking of buying 2x 1tb Samsung SpinPoint F3 7200rpm 32mb cache drives for £45.74 each
These are obviously highly rated as raid drives in these forums and I can't find anything smallar than a 1tb version of these drives at the shop I plan to order from – or is 1tb all they come in?
1st disc for OS and programmes
When going to the trouble of setting up raid is it acceptable to use an ide disc for the OS and programmes? I ask this because the 160gb WD hdd mentioned above has hardly been used....
If the ide drive is not approved of I'm thinking of buying either
1. A 500gb Seagate Barcude 7200.12 16mb cache sata 2 drive for £29.73 or
2. A 500gb Hitachi Deskstar 7K1000.C 7200rpm 16mb cache driver for £29.30 or
3. A 160gb samsung SpinPoint 7200rpm 8mb cache drive for 24.96
I know the Seagate and Hitachi are huge drives for the principal purpose of storing the OS and programmes but they both have 16mb cache and are only a few pounds more than the 160gb Samsung drive with only 8mb cache
Or
considering I'm going for F3 spinpoint for the raid discs would it be better, in terms of compatibility between the drives, to go for a spinpoint 8mb cache for the OS and programme discs
What should be my biggest concern here – compatibility between the discs or a higher cache on the disc - or considering they are all the same speed (7200rpm) does the cache not matter that much?
2nd disc for page file, media cache
I was thinking of dedicating the 500gb WD I have for these purposes. I've read in this forum that the WD drives are not that reliable when it comes to raid arrays – apart from that they seem to have a good reputation.
3-4th discs for raid 0
My mind is pretty much made up on the Samsung SpinPoint F3's
Partitions
Because there are a huge number of gb's in this set up I'm thinking of partioning the 1st and second discs so that in addition to using them for 'the operating system and programme files' and 'page file and media cache' their second partitions can be used to backup the data stored in the raid array.
Is it good practice to partition dedicated discs in this way?
THE GPU
Due to it's reletive cheapness, wide spread use and endorsement amongst gamers and workstation users alike, first of all I was swayed towards the 480GTX and using quadro driver hacks. But I couldn't get the number of ''risk factor' forum threads concerning making a GTX think its a quadro – particularly when it comes to using 3d max - out of my head. Even without the hacks there are a high percentage of grissly stories out there concerning the 480s and 3d max compared to workstation cards and 3d max. So I've decided that because I have the budget to get a workstation card (an ATI V7800) for 'just' £134 more than a GTX480 (£424 compared to £293) then for the peace of mind of more stable drivers, when getting to grips with a complex new programme, I might as well go for it and pay that bit extra.
I've had a good look at both the ATI V7800 and the PNY QUADRO 4000.... the differences between stream versus cuda and how these cards perform when rendering 3d programmes..... I started vearing towards the V7800 when I realised that when it came to rendering it was being compared very favourably with the quadro FX5800 let a lone the much cheaper quadro 4000.... Plus with the disc set up I am now thinking of I can buy the V7800 plus all the discs talked about above for £10 less than I can find the quadro 4000 for alone.
The only thing I'm concerned about is the V7800's compatibility with the cs4 design premium suite.
This page indicates that although some of these cards were released after cs4 they are supported by it.
http://kb2.adobe.com/cps/405/kb405445.html
Would it be wrong of me to suppose that, because the new V7800 is a work station graphics card, it will be supported by cs4?
What difference will it make if it isn't supported?
Having said that the quadro 4000 isn't listed as supported on this page either....
What would be your choice between the quadro 4000 and ATI V7800?
THE MONITOR
The monitor I'm looking at the 22” Dell 2209WA eIPS..... Although older (2008 vs 2009) the slightly larger 24”Dell 2408WFP has also caught my eye due to the higher contrast ratio (1300:1 vs 1000:1) and that this increased contrast ratio means it is capable of displaying 110 percent of the NTSC gamut as opposed to 86% with the the 2209WA.
I'm familiar with monitor on the 2006 dell XPS M1710 laptop and am very impressed with colour fidelity. The 2408WFP does require more calibration tweaking by the sound of it....
Anyone any experince of either of these monitors?
I'm off to the gym for an hour or so - I'll be back in a couple of hours

My strong advice: Don't skimp on price on hard drives.
Get high MTBF RAID edition drives (e.g., Western Digital RE-series drives).
http://www.wdc.com/en/products/products.aspx?id=30
In my main workstation I currently have two 1 TB WD RE3 drives that have been spinning in a RAID 0 configuration 24/7 with ZERO problems for a year now.
I figure one wants to minimize the chance of losing one's data down the road. How much would it cost you in time, effort, and lost work to recover your data from a backup if you should lose your hard drive?
Top-end drives can fail, sure, but the MTBF numbers say that the chances are much smaller than with "cheap" drives. And the RAID edition drives have additional features, such as vibration reduction, that differentiates them from lesser drives.
Ask yourself, why would one drive be cheaper than another? Poorer quality materials? Not as much quality control?
Another bit of info: Search this forum for "quadro". It seems that these expensive video cards may be seeing more trouble with Photoshop than you might expect. Some of the less expensive cards, that may have had more OpenGL testing (e.g., to support gaming) might be better choices for use with Photoshop. Personally I prefer ATI.

Can Grid control 11g monitor Oracle 9i database

Can Grid control 11g monitor Oracle 9i database? This is on Linux5.7
Thanks for the help

Yes but Enterprise Manager 11.1 Grid Control requires the 11.1 Agent.
Then go to the Targets tab, then Databases. It should self-discover the 9i database.
