Kepware Server OPC

Bonjour,
au sein de notre établissement (IUT) nous souhaitons mettre en place un serveur OPC pour réaliser une supervision globale du batiment (GTC + Supervision de systèmes de prod automatisés) à l'aide de LabVIEW. Nous avons acheté le Serveur OPC Kepware (KEPServer V5).
Le serveur OPC est installé sur notre "serveur de manip" appartenant à un VLAN de classe 3. Lorsque j'essaye de créer un client OPC (appartenant au même VLAN) sous labview en suivant cette procédure : http://www.kepware.com/Support_Center/SupportDocuments/KTSM00032_LabVIEW_Connectivity_Guide.pdf , tout se passe bien jusqu'à l'étape 3.2.2 lorsque j'interroge les variables liées leur valeur reste à 0 en permanence.
Pour m'assurer que le paramétrage du serveur OPC était OK j'ai interrogé le serveur OPC KEPserver grace à l'OPC Quick Client (sur un PC client du même du VLAN) et là les données interrogées sont bien actualisées... Donc à priori la config DCOM+pare feu est bonne.
Que dois je faire ?
Config Server :
Windows server 2008
Labview 2010SP1 + Module DSC
OPC KEPServer V5
Config client :
Windows 7 Pro
Labview 2010SP1 + Module DSC
Merci d'avance pour vos réponses.

Can't connect to KepWare Enterprise OPC server

I am trying to connect to the Kepware Enterprise OPC server with Server Explorer 2.4.1 but get a message 'The system cannot find the file specified' 0x80070002. I have modified the DCOM setting for XP SP2 as described in the Kepware documentation. Is there a way to resolve this issue?
Thanks
Harry

Hello,
Can you explain exactly how you are attempting to connect to this OPC Server and also any of it's properties that are set in Server Explorer. At what point do you get this message? Have you been able to connect to that OPC Server on that machine, or any machine before?

Connection to server OPC NI

Hello,
I need help, I try to connect a software developped with LabWinows/CVI 9.0 to the opc server of National Instrument.
The tag is "opc://localhost/National Instruments.Variable Engine.1//./QGAPro/5_2" or "opc://localhost/National Instruments.Variable Engine.1//./QGAPro/5_4" for example.
But the program returns "Error: Can't add item to OPC Group. The item ID is not defined in the server address space or no longer exists in the server address space."
I can check the tag with client opc like :
How can I know where is the problem please?
Do you know where is the problem?
Thank you.
Bye. Karine.

You can find below a piece of code.
I can connect to the server OPC with a client test, but I can't in my program.
char opc_target[] = { "opc://localhost/National Instruments.Variable Engine.1//./QGAPro/            " };
static DSEnum_Status status_inline = DSConst_Unconnected;
static DSHandle dsHandle[512] = { 0 };

            break;
    return;
I can't modify tags because this is another software that generates and which is developed by another company.
I have to read these tags to retrieve the associated values (values of a gas analyzer).
Can you help me with these informations please?
Thank you!

OPC/DSC/Kepware Server

When I attempt to deploy my application, I receive "Deployment failed: The client process cannot communicate with the configuration server process....."
I have DSC Run Time module on the target machine and I can read the OPC tags on the Kepware Quick Client so I narrowed it down to something to do with LV. I've read about the "identity of interactive user" and I do have that checked in the DCOM for the client server.
Thanks in advance for the help/ideas.

Daniel, here is the error message I receive.
The OPC server is located on 192.168.1.10 so it is the same subnet

Problem to connect with OPC Server opc.sinumerik.machineswitch using DS_Open

Hi,
I want to connect to an Siemens OPC server type opc.sinumerik.machineswitch using DS_Open calls (CVI 6.0) to read few tags. Running my client software (as well as the NI- sample test client) locally on the same computer as the server the connection works and I can access the tags.
Running the client-software on a remote PC then the DS_Open call "hangs-up" (not even an error message). All the DCOM settings etc should be ok, since I can access the tags using the Siemens Client OPC-Scout as test client.
I have used the same calls in several previous applications and it works with other servers (Bachmann, WinCC), so I am pretty sure that I use the correct URLS etc.
What can be the reason for a specific incompatibility?
Any idea is highly appreciated.
Cheers,
Ronald

Hi Roland,
as experience shows, Remote DataSocket is hard to implement.
The best way to implement this communication is the following:
First of all, check the DCOM -Settings
Using OPC via DCOM with Windows XP
http://www.opcfoundation.org/DownloadFile.aspx?RI=326
Use the “NI-OPC Server” to create a tunnel between the Siemens OPC server and your PC.
Install the NI-OPC Server on your PC and use the “OPC DA Client Driver” to access the tags on the Siemens OPC server.
After that you can access the created tags in the NI-OPC Server with CVI and DataSocket.
Please download the NI OPC Servers Evaluation-Version to test communication.

Is it possible to connect labview with opc server without using NI dsc Module ?

Hellow sir,
I want to get data over labview using OPC server and i am not using any dsc module vi (Alams, print, GUI, security).I am using share variable to get data from OPC server to labview. Now i want to deploy that application to third party computer. (where there is no NI software is installed)
i am using labview 8.6 and 2009.
Many ? like....
1) what is the procedure to install that application in third party computer.
2) Do i need to use my dsc run time licence..?
waiting for your valuable feed back.
Thank you.

Hi, When you connect to NI OPC Server by creating New I/O Server > OPC Client. You will see all registered OPC Servers running on local machine or remote machine. I used KepServerEx from Kepware and LSIS OPC Server from LG with no problems. Just make sure that the OPC server is running.
Hope it helps

OPC server items not found with NI DSC nor datasocket

Hi,
I am using LabVIEW 2009 SP1 and an OPC server from ifak (isPro Multiserver v 2.5.1) on a windows XP professional SP3 platform.
If i use the datasocket vi "browse for URL" then I can navigate to the server, it starts the server (I can see the hardware "coming to live" and logging on to the UUT -the network is a profibus network with 1 USB/profibus gateway as master and 1 UUT profibus slave. However, when navigating through the branches of the server I can not navigate to the OPC items. I can navigate to the point where they should be, but then the browser waits a few seconds and then displays "no items" and places a red cross through the icon.
When using the manufacturer OPC client, I can navigate to the items and I can see them, read them or write them. The funny thing is that I can also browse to these items using the NI Quick OPC client(!) When using datasocket VIs, or when configuring a project using the DSC module --> new I/O server --> OPC client --> browse to OPC server and then trying to configure the labview library to hold the OPC items, I never get to see the actual items.
This seems to be a DCOM problem but I can not believe that, since
1) the manufacturer OPC client sees the items
2) the NI Quick OPC client sees the items
3) I followed all guidelines from
http://www.automation.com/pdf_articles/OPC_and_DCOM_5_things_you_need_to_know.pdf
and
http://www.automation.com/pdf_articles/Troubleshooting_OPC_and_DCOM.pdf
and I also set the OPC server access to "the interactive user", as recommended by NI.
The OPC server and OPC client reside on the same computer, but in any case I also disabled the windows firewall. There are no other firewalls running.
I am completely stuck in this application, since I can access the OPC items using any client, but I can not access them via LabVIEW
If anybody has a suggestion, please help me.
best regards,
Stijn

Hi Stijn Schacht
These seems to be some bugs with OPC Client instances created using LabVIEW 2009 SP1, when we tried to communicate to Siemens S7 PLC.
Basically when deploying the shared variable library configured with OPC Client instance, it crashes the SVE.
From all your observations, what i can suggest is, try with LabVIEW 2009 along with DSC 2009.
Thanks,
Vijay Jayabalan.

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 KB

Hello 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.

Switching Kepware servers in PCO

Hi Experts,
We have Kepware on a different machine and PCO on another machine. To connect the Kepware server we installed 'OPCCoreComponentsRedistributable(x86)' on the machine where PCO is installed. we were able to create a source system using the details of the kepware server. For some testing we are trying to re-point the PCO to another Kepware server. For configuring the other Kepware server, we made the changes to the 'opc_remote' file to specify the details of the other kepware server. After making the changes to the file, we re-started the server on which PCO is installed. After re-starting when i am trying to create a source system using the details of the new kepware server, i get message 'No OPC servers found on the specified machine'.
If i specify the other Kepware server that was provided earlier, i am still able to create the source system.
I know that we can connect to only one Kepware server from PCO, but is it that we cannot switch from one Kepware server to another.
We are on PCO 2.3 SP04 P7 and Kepware server is V4.190.341 - U.
Regards,
Darshan Sheth

Darshan,
For DCOM to work with PCo and Kepware, you have 2 options to configure the user access:
1. Allow full DCOM access for domain users that are members of the server Administrators group, EVERYONE, SYSTEM and NETWORK, and allow PCo and Kepware services to run under LocalSystem account (some network admins will not allow this as it opens potential network security holes)
2. Define named users or named Domain Group permissions for DCOM.
2.1. Use the named user or users that are members of the named Domain Group for the following:
    - named user for Kepware server_runtime service
    - named user for PCo Agent Instances
    - administrative user to log into to PCo remote Desktop
Avoid hosting PCo and remote OPC Servers on different Domains or on Workgroups -- should always be in the same Domain.
I strongly recommend that you migrate to Kepware V5 and investigate using the Kepware OPC UA interface along with PCo OPC UA Agent where you are going to have remote OPC Server requirements, and avoid the DCOM issues altogether.
Installing Kepware on PCo server, or PCo on the Kepware server will remove any DCOM configuration requirements.
Regards, Steve

Why cant i see the opc servers on the computer where labview is running?

Hello,
i have 2 Computers in a network. On both computers is installed the NAPopc Server. On the computer where Labview is running, i can not
see the OPC Server wenn i go to ->my computer->new I/O Server-> OPC Client. The box of registered OPC servers is empty.
When i choose the network connection, i can see the OPC Server on my other computer.
Can somebody tell me why? I want to use only on computer for my project...
Thanx, Daniel
Best reguards

Hi Daniel,
in your post you're saying that you have the "NAPopc-Server" installed. Did you mean the NI-OPC-Server? As you can see in the screenshot attached you should be able to see any registered OPC server that is registered properly, no matter if it's installed on your local host or elsewhere.
You mentioned that you can see the OPC server on the other computer, so you should be able to see the OPC-server on that machine when you choose the settings-tab and select "localhost" as machine. Is that right?
For further troubleshooting tips look here and here

Bernd

Configuration serveur OPC

Bonjour
Je travaille avec la version 8.5 de labVIEW et j'ai à ma disposition le NI OPC Servers 2009.
Je souhaite réaliser une application OPC distante c'est à dire avoir mon application LabVIEW sur un poste (PC1) et mon serveur OPC sur un autre poste (PC2). L'application Labview doit envoyer les données sur le PC2. La communication entre les deux PC est de l'Ethernet, et j'utilise les datasocket de Labview pour me connecter au serveur OPC.
Avec l'application labview en pièces jointes, j'arrive a voir mon serveur OPC distant (sur le PC2).
Mais je n'arrive pas à configurer le server OPC. Je n'arrive pas à céer des items sur le serveur.
Lors de la configuration du serveur on doit choisir une "channel". Mais je ne sais pas quelle option choisir pour pouvoir me connecter à LabVIEW. J'ai essayé avec la channel "OPC DA client driver mais je n'arrive pas à me connecter à LabVIEW.
J'attends votre aide avec impatience
Merci

Hello, CMH....I apologize for not answering this question in frech but je ne parle pas frances...
Anyway, If you have labview 6i, you can access the OPC server either using the DataSocketopen.VI or using Frontpanel Datasocket.
Frontpanel Datasocket, in my opinion is the easiest. The only thing that you need to do is to create a control on the front panel, right click on the control, and then go to data operations/data socket connection and then browse(browse measurement data)and select the OPC Server/item that you are using....this is pretty straight forward.
Now, if you want to use the datasocketopen.VI, you will need to have the right sintax at the URL connector in the Datasocketopen.VI in order to be able to communicate with the OPC Server.
The generic sintax for
the URL connector at the datasocketopen.VI to select an OPC Server/Item is shown below:
opc://
or
opc://?updaterate=xxxx
where xxxx is the update rate.
Below, you can see the URL sintax for a datasocketopen.VI used to get data from channel 0 of a FP-AI-100 module, using the National Instruments OPC Server.
opc:/National Instruments.OPCFieldPoint/FP Res\FP-AI-100 @1\Channel 0?updaterate=1000
where
is the OPC Server.
is the OPC Item
and
updaterate=1000 is the parameter for the update rate.
There are very good examples that come with LabVIEW 6i, just go to:
search examples/communication/datasocket OPC.
Check out the OPC to URL VI used for most of the examples. This VI helps you with getting the right sintax on the URL connector in the datasocketopen.vi.
Also, please contact the distributor of the OPC Server (Induscreen)and ask them the specific details on defi
ning item names with their OPC Server.
I hope this helps.
Arevoir.

ABB SattLine OPC

Hi
I have tried to communicate with the ABB SattLine OPC server (ADS.OPC.2 in figure 1).
I can read connect and read/write tags with the Matrikon OPC explorer,
but have problems with labview.
I can see and browse the server however I do receive a message which
says "the server is connected and can be browsed but it will not be possible
to retreive extended item information"...
I can see the tags but when I select the proper tag Labview just shuts down (figure2)
I have no problem can communicate with the same code with MATLAB OPC server
with MAtrikon opc server and the Labview OPC servers (simulators) no problem
at all, just in the case of the Sattline I have thi behavior.
Any comment would be highly appreaciated.
Cheers
Zoltan

Hi,
I still have problem to get arround this thing....No rpogress at all.. but here it is what I did:
1. I found the server explorer on the NI site and installed. I can read/write the data
ABB server (ADS.OPC.2) beutifully, see ( the figure attached).
2. In LAbview 8.0 with DSC 8.0 I tried two things:
2.a - the same as before. If I try to use any of the OPC examples from the opc.dll
e.g. "Browse to OPC item.vi" I can open the browser, I can see the OPC server
I can even see the group and the tags, but when I click on any of the tags again
Labview crashes with the error message (see the figure). This is the same original problem...
2.b - Now still in Labview 8.0 where I have DSC 8.0 installed I added to a new project
New --> I/O server --> OPC --> and add the ADS.OPC.2 from the list of registered OPC servers and add
as a linrary to the project ( this is fine so far)
But when I right click on the newly added OPC1 and check the View I/O items I cannot see any tags.
(when I dod the same procedure with any other OPC server, e.g. MAtrikon no problem).
The same if I still go ahead an to add new variable I cannot see the tags from the server. Only
the NI OPC CLient Status group appears (which does not belong the the ADS.OPC.2).
3. Finally, I downloaded Labview 8.5. I do not have DSC 8.5 so I only tried method 2.a. That is the simplest
example from the opc.dll crahes Labview.
During all this time I have no problem to communicate in Labview with other simulated opc sertvers,
and at the same time I have no problem reading/writing data to the real ADS.OPC.2 using other
the Matrikon or the NI server Explorer...
I am running out of ideas ...:-(((
Thanks

LV DSC 6.1: no tag refresh?

Hello:
I am using DSC 6.1 with LabVIEW and have the following issue: in the tag configuration editor I define tags originating from both the LabVIEW OPC server example (National Instruments.OPCDemo) and the Kepware simulation server. In the tag monitor tool I can see that all tags' quality are "good" but only the LabVIEW OPC server example tags update continuously although other OPC clients software reveals that the Kepware tags also should change continuously. Now if I stop/start the tag engine I will get updated values (once) then it stops again refreshing. I set the deadband to 0 and it does not change anything. No noticeable tag definition differences between the LabVIEW server tags and the Kepware tags. Any clue would be much apprecia
ted, thank you,

Sorry, I was a bit in a rush so I was not attentive enough.
Here is another possible solution:
Change the OPC communication mode in DSC to synchronous communication for the Kepware server(default is asynchronous and some OPC servers don't work correctly using this method).
To do this navigate to Tools -> DSC Module -> Advanced -> Server Browser and click on the button labeled "OPC Client Settings".
Then hit the "View All" button and select the Kepware server from the list and hit the "Add" button.
Now your OPC server will appear in the Synchronous Communication list.
I hope this helps.
