Which services i need to work wit OPC Server

Hi, I've been working with OPC Servers in labview, with a micrologix PLC, but last week someone was messing around with my laptop, and I discover that all the National Instruments services were disabled, and i need to know which ones I need, because I enable all of they but when I go to the Quick Client option in the OPC Servers tool the program ask me for NI LabView Run-Time Engine 7.1.1, I have Labview 8.6 with DSC module installed. I never have this problem until today and I dont know wath to do.
I'll really really appreciate any help ypou can give me.

You can find more information about OPC Servers at:http://www.ni.com/opc/
. There you can download the OPC Servers Software and reinstall it
again with all the components.
Also here is a
video where you can see how to connect LabVIEW to any PLC using OPC
Servers:
http://zone.ni.com/wv/app/doc/p/id/wv-263
Remember
that you must to have the license for use OPC Servers.

I have an existing application need to add LabVIEW OPC Server

I have an existing application written in LabVIEW which controls a Device. The data from the device is currently logged to the local drive.
It is desired to upgrade this application to become an OPC Server so that the manager can remotely acquire data and control the Application.
What would be the easiest approach to accomplish this task?
Thanks and Best Regards,
Gary

Hello Dan,
1. The operator specifies a time interval to save the data to disk. The data is stored in a csv file.
2. The manager is the Engineer who is managing the data collection system remotely.
3.The desired end result is to have the LabVIEW with an OPC server provide the connectivity to an OPC client so that they can collect the data, that they desire from the system, and control the system.
4. Controlling the system is secondary. Providing the connectivity so that an OPC client can specify what data is to be sent and the update interval is the first priority. For example, they may only be interested
in 10 of say 30 parameters, and want that data sent over every 10 seconds or so. The data once they receive it will be logged to a central data base.
We suggested using TCP/IP but they do not want a custom interface.
We also suggested Modbus, but they perfer to use OPC. The want to integrate it with their OSI PI.
Thanks and Best Regards,
Gary

Can iTunes tell me which songs still need art work?

...without me having to go through each album.

iTunes can be scripted, for example, to create a playlist of all the tunes without artwork.
I dont know if a windows version of this mac script exists but it is also possible to then create a script to then populate the artworks automatically as shown here.
An example of a PC iTunes script is this one.
There is no other way that i know of at present.

Getting a second server, suggestions for which services to put on each?

Hi we currently have one Xserve (G5) which runs all our services, but are about to get a new Xserve and I would like a bit of guidance as to which services I should keep together on one server and which I should move.
Because the two servers can't run the same OS (one leopard one snow leopard) I know there are some things I cant do, like OD replicas.
But is it best to keep OD, DNS,AFP, DHCP on the newer server and move other services to the older one.
We use Kerio for mail/cal, Rumpus for FTP and Retrospect for backup, also have iChat server and wiki server running.

It depends a bit on number of CPUs, RAM and such in the old machine.
But generally I would consider the old one for lighter ("backup") duty putting most, all essential services, in the new machine.
If you run Kerio with the "OD connection" (users and groups from OD) and put the OD in the SLS (new machine) and Kerio in the old LS the "Connected to a directory service" must be used/work.
This can mean if the SLS stops responding (Kerberos/LDAP) for some reason mail accounts will not be present in Kerio until that is fixed - incoming mail for those accounts will "fail".
DNS can be used on both preferably setup as master/primary and slave/secondary.
What machine to run Retrospect on depends on what version/license ("multiple servers" license? - if not you might not be able to use Retrospect Remote on one of the servers), backup type/backup device and other hardware (SCSI card?) used. If using removable backup disks I'd probably use the G5 for Retrospect, especially if it's the older ≤ 6.1.x version, otherwise probably the newer Intel machine.
I haven't used Retrospect to backup system/configuration, just data.

OPC server setting

Hi
I`have developed an application client which has shared variables bounded with an OPC server of NI. Sever and Client are on the same machine. My executable works very well.
Now if I want install my executable on a machine that has not the OPC server installed, so I need to change manually the path of the OPC server and of all the shared variable bounded before creating the executable.
Is there any possibility to set the path of the OPC server on the front panel of the application? Any suggestion how can I develop a VI to set this path?
Thanks
Vincenzo

Hi Vincenzo,
I've never tried it, but I guess the "Create&Configure IO Server"-Express-VI should do the job (DSC Module/EngineControl/Variables&IO-Server). It allows you to dynamically setup a connection to an OPC-Server (or other server type).
If you use the "Overwrite if I/O-Server exists"-Option and use the name of your original I/O-Server, all your Shared-Variables connected to that Server should (hopefully) automatically connect to the new OPC-Server.
As I mentioned, I did not try this. So, let me know if it works.
Good luck,
Thomas

DSC toolkit and OPC server

Can I datalogging data from OPC server directly to SQL without "datasocket", and how, example maybe?
Thanks
Rookie; LV 2011 on WIN 7

Dear hlod,
Can you provide me more information about your application, and why it is'nt possible for you to use DataSockets?
If you want to use OPC servers for connecting to PLCs, I can recommend the followings:
Here is a great tutorial, how to work with OPC Server to connect to PLCs:
Connect LabVIEW to Any PLC Using OPC http://zone.ni.com/devzone/cda/tut/p/id/7450
After the tutorial you're able to communicate with PLCs through NI OPC server, using I/O Server instead of DataSockets.
Datalogging into Databases are also made easy with LabVIEW DSC Module. Look at the following tutorial:
Data logging Options Using the LabVIEW DSC Module http://zone.ni.com/devzone/cda/tut/p/id/12525
For more specific solutions, feel free to browse either the LabVIEW DSC Module Help from LabVIEW, or Online: http://zone.ni.com/reference/en-XX/help/371618G-01/
If you have different, more custom application, which I can help you with, please post on forum some more specification of your task you want to do.

Joining Actuals and Planned Work from Project Server

Hi,
I have an SQL based query which returns Actuals and Planned work from Project Server; however a number of records (generally generic resources based on the ResourceIsGeneric column) are excluded. I believe this is because my Actuals query does not return
generic resources as we are joining both sides of the query on ResourceUID. I have included a snippet below - is there a way to join Actuals and Planned work so I can return all Resource data?
Thanks

Hi,
you pasted just part of your query, e.g. is declaration of @ParamTable missing. Without complete query, it is difficult to see, what you are trying to do.
Could you please provide complete query?

I've become increasingly frustrated with the ipad adobe app. I've subscribed to be able to convert my pdf files into word documents and it has yet to work I've paid for a service that does not work which in turn makes me a disgruntled customer to say the least very disappointed with such horrible service

Which service did you subscribe to? Adobe PDF Pack?
Once I know the service that you subscribed to, I can move this post to the right forum so that you can get in touch with the folks who can assist you.

Which service pack is needed?

Hi ...
Can anyone please tell which service pack is needed to integrate ERP system to TM system using PI 7.1?
Can anyone have the knowledge on TM system? Could you please explain in detail.
Thanks & Regards,
Leela

Hi,
Integration of Master Data can be done by using the CIF. For more information about the PI interface take a look at: Support Portal, Software Download, Support Packages and Patches.
Search for "TM", and you'll find XI CONTENT SCMTM.
I hope this will help.

ICal Service Data Recovery not working.

Hi,
After upgrading to 10.5.4 (not sure yet if this is the cause), my iCal service stopped working, with CPU on the Xserve getting maxed out whenever it ran, as per the earlier post in this forum. Following suggestions in that thread, I used a Time Machine backup I have of the server HD to recover the most recent copy of the Library/Calendar/Documents folder using the following command,so as to preserve permissions and ownerships etc:
sudo ditto -V -rsrc <source directory> <destination dir>
The data copied across fine, and when I point the iCal service to use the new data location and start up the service, all the data is there, but no new events can be created, as the client app (mail 3.0) reports...
Request for "New Event" in "James Glendinning" in account "James Glendinning" failed.
The server responded with
"HTTP/1.1 500 Internal Server Error"
Looking at the error log for the iCal service, it's full of stuff I don't understand, which is logged as soon as the service is started whilst pointing to the new data location:

I'm particularly perplexed by the last line, which indicates that ....principals/ _uids__ location does not exist, when I can clearly see it from within finder, and it appears to have all the permissions intact.
Is there a way I can get the iCal service to keep all the calender entry data it has, and rebuild any of the other bits it needs on the fly? Or any other ideas at all?

OK, great, I tried that on the busted data location, and it still didn't work, I think there's some corrupt dblite files of something. In any case, I've given up, instead I've created a new store, and set the permissions as you've described, and am rebuilding each calendar individually, which is a pain, but I needed it working asap.
I'll see how the new data location holds up with this new data and post results.
Thanks for your help....

NEW CUSTOMER WITH INTERMITTENT SERVICE - IN NEED OF ADVICE

Let me preface this post by stating that I am a new Verizon Customer, as of a few weeks ago. I've really enjoyed my Verizon FiOS services, which consist of the Verizon Triple Play with the upgraded 35/35 internet package. I have wanted the service for quite a while, but it was not available to me until I moved to VA.
With that said, I am asking for some help in diagnosing the following issues that have plagued me for the last two days going on a third.
11/23 (Wednesday): Data stops working. No "Internet" or "WAN Coax" lights on router. Chat with Verizon Support online who walks me through a reboot followed by a reset/restore of router, neither of which, work. He then schedules a technician for the following day.
11/24 (Thursday):
10:30 am - Technician arrives and gets cracking on the problem. After a short time, he determines the modem needs to be replaced. He swaps it out for another and data is restored.
1:30 pm - Data fails again. This time my "Internet" light is orange and the "WAN Coax" light is green as normal. I contact Verizon Support, via telephone, and he walks me through the entire reboot followed by reset/restore of router again. This does not work. He ends up remotely restarting my ONT, which gets my service working again.
3:30 pm - While on the phone with family, my call was disconnected abruptly. I go into my office to see the "Internet" light is orange again. I call Verizon Support and am once again run through the entire reboot/reset process. This does not work. Instead of the remote reboot, she walks me through manually rebooting the ONT by unplugging the power and battery. The service is restore and working correctly again. Regardless, she still scheduled a technician for the next day.
11/25 (Friday):
10:15 am - Technician arrives. I describe the intermittent issue occurring since his visit the day before and he proceeds to replacing the ONT. He even replaced the coax cable from splitter all the way to the modem. He cleaned up the slack in all the original wires and really took his time trying to make sure everything was good. I was really confident that this was a done deal.
8:00 pm - Really bad failure this time. FiOS internet, telephone, and TV all fail. I got on the phone with Verizon Support and after explaining the whole story, she was nice enough to not waste my time with a router reboot. She read through my log of support calls and service visits and automatically scheduled a technician for tomorrow. We'll see what happens next.
Since getting off the phone with support, I manually rebooted the ONT and all services are restored. Hopefully this will tie me over until morning.
I've read a number of threads on this forum and have noticed that there are some pretty sharp guys and gals here who seem to be able to successfully trouble shoot these types of problems without ever being there. I am hoping this post falls into that category. I really want this fixed and do not feel like losing FiOS in the pursuit of consistent service. Any help that any of you can provide will be greatly appreciated.
Thanks in advance!
