Labview 7.2 OPC VI's Work, but 8.0 VI's Give Error 1101
I am a novice Labview 8.0 user. I am trying to set up OPC connections to collect some data. Another engineer sent me an OPC Data Socket VI created in Labview 7.2. This one works, but when I try to duplicate the reading of the exact same data in 8.0, I am getting an Error 1101.
I would use the 7.2 functions, but they no longer show up on the Data Communication palette. And, I don't know what to do to get the 8.0 versions beyond Error 1101.
Any help is appreciated.
It sounds like you need to set up the privileges using the DataSocket Server http://digital.ni.com/public.nsf/allkb/6941F7A4DBBC1B0886256CEE0082A3CB
Don't remember if this changed from 7.x to 8.x and am not where I can look at my machine with 7 on it. I've never seen a version 7.2, think that the last 7.x was 7.1.1

Windows 7, firefox 1.6.16 just installed office 2010, sometimes cannot open a link in outlook and firefox is my default browser, and firefox will not initiate at all. Have to restart computer to get any response which then works but after a while it crashes again. Was this due to an update or office 2010 has a hidden setting somewhere? Why would firefox crash without any message? Intimated consuming
I have had a similar problem with my system. I just recently (within a week of this post) built a brand new desktop. I installed Windows 7 64-bit Home and had a clean install, no problems. Using IE downloaded an anti-virus program, and then, because it was the latest version, downloaded and installed Firefox 4.0. As I began to search the internet for other programs to install after about maybe 10-15 minutes my computer crashes. Blank screen (yet monitor was still receiving a signal from computer) and completely frozen (couldn't even change the caps and num lock on keyboard). I thought I perhaps forgot to reboot after an update so I did a manual reboot and it started up fine.
When ever I got on the internet (still using firefox) it would crash after anywhere between 5-15 minutes. Since I've had good experience with FF in the past I thought it must be either the drivers or a hardware problem. So in-between crashes I updated all the drivers. Still had the same problem. Took the computer to a friend who knows more about computers than I do, made sure all the drivers were updated, same problem. We thought that it might be a hardware problem (bad video card, chipset, overheating issues, etc.), but after my friend played around with my computer for a day he found that when he didn't start FF at all it worked fine, even after watching a movie, or going through a playlist on Youtube.
At the time of this posting I'm going to try to uninstall FF 4.0 and download and install FF 3.6.16 which is currently on my laptop and works like a dream. Hopefully that will do the trick, because I love using FF and would hate to have to switch to another browser. Hopefully Mozilla will work out the kinks with FF 4 so I can continue to use it.
I apologize for the lengthy post. Any feedback would be appreciated, but is not necessary. I will try and post back after I try FF 3.16.6. -

[SOLVED] Alsa works, but not pulse (pulseaudio: symbol lookup error)
SOLUTION: Fixed in latest pulseaudio. Build from latest git, or use AUR.
I've just installed Arch following the beginner's guide, managing to get an up to date system, Xorg working with Awesome, and positive results with systemd. My next goal was basic audio and video.
I installed Alsa, added myself to the audio group, tested the playback and recording with arecord and aplay, no problems.
I installed mplayer2, which pulled `libpulse=0.9.22-2` as a dependency.
Mplayer2 did not work. It looked like it had something to do with pulseaudio, but I didn't look too hard before removing mplayer2 and libpulse.
Installed pulseaudio, pavucontrol, paprefs, avahi. I want to use mplayer2, but mostly I want pulseaudio for its own merits, especially its network transparency. I'm also hoping it fixes a skype problem.
Tried running `pulseaudio --start`, but it fails returning this error:
[jake@clyde pkg]$ pulseaudio --start
pulseaudio: symbol lookup error: /usr/lib/libpulsecommon-0.9.22.so: undefined symbol: STRING
Here's also a snippet of strace, I can post the full log if it would help.

Do I just need to do a "proper" exit?
Thanks,
TimGiven the order of the syslogs, I'm guessing that we're looking at multiple instances of the policy running. Since you're allowing them to run for 60 seconds and scheduling them 60 seconds apart, that's probably the case. My guess is that some of the SSH sessions are not providing a match to the "assword:" pattern, and thus these policies are hanging awaiting the prompt until they are terminated. I would check to make sure you don't see some other pattern on various runs of the SSH command.

Download link didn't work but itunes still took money, what to do?
I pre ordered album from itunes with iPad and got that link where I can download it. That link didn't show up anywhere and this didn't load music to my iPad but still on my Apple ID they have took that money...What I do to get my album or money?
There are several photo apps but I've never used one so I really have no recommendation.
How many photos are you talking about? If it's a few you can e-mail them to yourself.
If you have the camera connection kit you can use it to transfer p hotos with a SD card. (USB flash drives might work but it usually takes trial and error to find one that doesn't trigger the 'device requires too much power' warning)
If you use the SD card you make a folder named DCIM on the card, then make sure all your images have names of exactly 8 characters, DSC_4757.jpg for example. And that all those images are inside the DCIM folder. You then connect the card, open the photos app and import the photos.
Alternatively you can use a service such as dropbox or other file transfer service to upload the photos them download them onto your iPad. -

How to convert labview data into opc tag
Hi all,
Can any one please tell me how i can convert the labview data global into a OPC tag? I have some data globals reading and writing data to the globals. Now i wanted to use a PLC device to send its outputs to the field.
The PLC device will supports the OPC tags so i wanted t create OPC recognised tags in my labview. Is it possible. I saw that labview also having OPC functinalities. Please any one guide me in doing this.
I will be very thankful to them
Ramme..As I said, I believe you can do this for globals as well by opening its front panel (double click the global) and using a DS connection for the control that represents that specific global.
As for other alternatives:
NI sells the DSC module which comes with an OPC server and with better tags.
You can use a common protocol like Modbus to interact with the PLC.
You can use the custom protocol used by the PLC.
The last two would require that you would change your program structure, so you would only want to use them under certain conditions.
I believe the practical limit for OPC tags with DS is a few hundred tags, but I never used it myself so I didn't run into it. You can try searching the forums to find out more.

VI works but executable file doesn't
I built an application in LV 8.2 to read in some binary data, create some graphs, and make a microsoft word report. The VI works just fine. However, when I build the executable file so that I can run it stand-alone, part of it doesn't work. I have an event structure which waits for user input from 3 buttons - Make Report, Open Report in Word, and Quit. Open and Quit both work fine, but Make Report just doesn't seem to do anything. When I built the executable, I made sure to include all of the source files. All of my stuff is in the zip file attached. The top-level is called Graph Report Maker. Can anyone help me out with this? I'm probably just doing something wrong when I build it, but I'm not sure what. Thanks.

Using the Abort button to stop your VI is like using a tree to stop your car. It works, but there may be consequences. -
We are running the latest Labview 2010 on new computers (Windows 7) but have the older/oldest NI ELVIS hardware (NI ELVIS I?).
Labview works great and the device drivers are installed.
Which NI ELVIS software do we install?
The latest version states that it is for the ELVIS II and III hardware,
Thanks,
Solved!
Go to Solution.Hello,
The ELVIS software installed fine and the ELVISmx Instrument Launcher runs fine.
However, when I try to run an instrument, we get the following error (See Attachment):

It seems that the software can't find the DAQ card which is directly hooked up to the ELVIS unit via a cable
We aren't using USB.
I noticed that the newer ELVIS units use USB only.
Is there a setup to make it recognize the card? There used run with the older ELVIS software when you clicked on Continue in the error box.
The PCI-6251 card checks out fine with MAX.
Thanks,
Tom

LabVIEW DSC 2011 / OPC Client IO Server / Can I write to the OPC Server using OPC Groups?
Hi
I am using LabVIEW DSC module as a OPC client. My Shared Variables are binded to automation system OPC Server via "OPC Client IO Server".
On the OPC Server side it seems that the every write commands comes like one item at time, not like grouped.
Now I have tested this with the NI OPC Server as server and KepServer and LabVIEW DSC IO Server as OPC Clients.
When I use the NI OPC Server : OPC Diagnostics there are different events messages when the update request comes from KepServer or LabVIEW DSC.
There are log files on attachements for both write events.
Attachments:
Data from the KepServer.txt 6 KB
Data from the LabVIEW DSC OPC Client.txt 18 KBHello Pentsi,
I have received confirmation (from the PSE in the US) that DSC doesn't support group writes
There however work-arounds that might provide a solution:
- The first solution I had in mind was like this. Update the 50 OPC items as fast as possible.
Then use a 51st item as synchronization OPC item to check/indicate if new data has arrived/has been set/is available.
So LabVIEW sets 50 OPC values as fast as possible. The 51st value becomes goes from false to true when the first 50 values are written.
When this (51st) value is true on the OPC server you can read out the first 50 values (from the non-LabVIEW side). When you've read out these values, then you can set the 51st value back to false (from the non-LabVIEW side).
In the meanwhile at the LabVIEW side you wait until the 51st value goes back from true to false.
When it becomes false, then you write again those 50 values and afterwards set the 51st synchronization value from false to true.
And this keeps on going...
Note: Keep in mind that you only have to monitor one event at the side of the Automation System OPC Server in this case (the 51st) and based on an event occuring over there you can just do a group read of the 50 others. Also keep in mind that the maximum rate (6500 updates per second) from inside LabVIEW with the DSC Module OPC client I/O server was also mentioned in this document (http://digital.ni.com/public.nsf/allkb/63C043359F1E12538625726E005BCD0C?OpenDocument).
Could this be a possible solution for your problem?
If you're using one of the OPC servers in this list (http://zone.ni.com/devzone/cda/tut/p/id/6417#toc19), then you can also use NI OPC Servers to update tags instead, which supports a faster update rate.
