OPC Server S7 1200 cannot pass data to VI

Hi,
I use siemens s7 1200 plc with labview 2011 and Opc server 2012. I can connect to opc server and create tags. Moreover, I am able to see data changes with quick client.
The problem when I try to create I/O server and bound with shared variable, I pass it to VI. All tags are zero, I believe there is no communication to servers. Although there is no error message. Any suggestions?
Please see the posts

Hello sir,
We are too handling a project and stuck with the same problem. The OPC quick client shows the updated value but while using the opc variable in the labview it doesn't shows any changes , So please help as with some good solution.

I'm late to the party, but if you need to troubleshoot OPC communications, you should start with opening the OPC Quick Client. Check there to see if you have good connectivity - if it is broken there, you will never receive data to LabVIEW.

Cannot pass data from Web Dynpro to XI using a Web Service

Hi All,
We have been facing some issues when we try to pass on a SOAP / XML message via a WSDL from a WebDynpro App to XI - No data is reaching XI interface. The payload data details for the inbound message in XI is empty. When testing the WSDL separately using XML spy the data passes to the XI successfully.
The problem only occurs when we pass on the data from the WebDynpro component.
We are also passing additional information _user and _password to ensure authenticated access.
Steps that we completed so far:
1. Created a WSDL which we can use to communicate to XI interface.
2. Imported WSDL using webdynpro Web Service Model import
functionality.
3. Bound WSDL with webdynpro components.
4. Pass on data through WSDL contexts.
5. Execute WSDL model.
Any help would be much appreciated.
Thanks,

Aplicacion Flujometro - OPC Server - Data Socket

Hola a todos:
Estoy realizando una aplicacion para poder capturar los datos de un Medidor de caudal con paleta rotatoria KOBOLD (flujometro) . Cuento con un PLC Micrologix 1200, tengo instalado su OPC Server correspodiente, asi como el Data Socket en una aplicacion industrial ...
Desearia poder realizar hacer una aplicacion sencilla para cerrar una valvula solenoide, cuando el flujometro marca un valor determinado

Hola JorgeEPD, para conectarte a tu OPC, solo tienes que indicar la dirección de tu OPC, y datasocket se encarga de la comunicación.
La única limitante que tienes es que vas a tener que realizar una conexión de datasocket por cada elemento de tu OPC Server.
AL solo querer realizar una medición (solo uno de los canales) es probable que con una sola conexión sea suficiente. Hay ejemplos en el find example de cómo usar Datasocket
Para facilidad de manejo de OPC te recomiendo el modulo de DSC de LabVIEW

Can I write arrays of strings to OPC server?

I am using shared variables for their built-in OPC server functionality. I have configured some of my SVs as strings, as arrays of doubles, as arrays of booleans, and as arrays of strings. When I connect to the NI shared variable engine using the MatrikonOPC Explorer OPC client application (a free app recommended for OPC troubleshooting on the NI website), I see data for all of the shared variables EXCEPT the SVs that happen to be arrays of strings, which show no values and a quality of "Uncertain, non-specific". If I use DataSocket to connect to the same SVs using their OPC URL, I see the same quality result (Quality=64). Is there something I need to do to ensure that SVs configured as arrays of strings work properly as OPC tags? (string lengths?, termination characters? etc). In MatrikonOPC "Array of Strings" is listed as a possible Data Type, so I assume that what I'm trying to do is not impossible. The reason I'm trying to have OPC tags as arrays of strings is because my system has a variable number of channels, and I want to transmit the channel name list to an OPC client. Does anyone have experience with this?
NI Software : LabVIEW version 8.6.1
OS : Windows XP

I've downloaded a couple of free OPC client apps (MatrikonOPC and CAS OPC) and they both seem to list an array of strings as a possible data type, though I can't say if that is a commonly implemented one or not.
You are correct that I would like the LabVIEW shared variable engine to act as an OPC server in my application. Data will be acquired on the PC running LabVIEW, and written to OPC tags for sharing with another PC on the network. I'm actually not positive what the client application will be, since it will be supplied by the customer that is purchasing the software. It might be Wonderware, but I'm not 100% on that.
If I am unable to solve this problem then I guess I can always create a separate SV/OPC tag for each DAQ channel and pass data that way, rather than my current method of creating only two SVs: one that is an array of channel names (strings), and one that is an array of channel values (doubles). It just seems a bit inefficient to create a whole bunch of OPC tags that may or may not be used, since the number of channels enabled and their names will all be based on a user-supplied configuration that may change from one run to the next. I'm not much of an OPC expert though, perhaps creating a whole mess of OPC tags is the normal methodology that people use.

CRIO communicating as PLC with NI-OPC-Server

Hi there,
i have the task to implement a communication between multiple cRIO's and the NI-OPC-Server. The NI-OPC-Server has to act as data handler for a complex frontend.
I tried out the NI-OPC-Server and i was successful in communicating with the NI-OPC-Server as OPC-Client in Windows using an IO-Server and Shared Variables. But the task is to do this on a cRIO. I tried to open a data socket connection from a cRIO to the NI-OPC-Server using a specific URL using "DataSocket Select URL.vi". But as long i do not activate simulation in the NI-OPC-Server i get errors on opening the data socket connection. If i do activate the simulation, which is not the solution, i can write some data without error but the Quick Client of the NI-OPC-Server sees no changes for that data tag.
I have the feeling i am not at a good way to get this working. Is there anybody having experiences with this? Is data socket a possible way at all? Is it possible at all? Do i need to implement a cRIO-OPC-driver?
Thank you.
Solved!

Stream DAQMX to an OPC server

i am trying to stream data sampled with DAQmx to an OPC server and have an external program pick it up fromt h OPC server
the external programe works with the OPC DA
can somone help with a small demo VI and or explenation on how to create a vi that will stream datat from a DAQ MX to an OPC server
thanks,
Assaf

Abaker,
Do you have the DSC Module? Also, what do you mean by streaming data? If you are just looking for the latest value that will be okay but if you are looking for a history of the data you will probably need to work out some sort of handshaking.
It would also help to tell us exactly what VIs you are using for the writer and the reader and what you are writing to on the OPC server. The dark blue data type is dynamic data type and just from what you have said it seems that your OPC variable does not recognize the dynamic data type, you may have to convert that. That is just a guess though and it would help to get more information.

Error 1101 - Cannot communicate with Experion OPC Server

Hello,
I am having an issue whereby I cannot Read/Write to an Experion OPC Server through Labview and Datasocket, and get Error 1101.
The Program is below.
- I have been able to connect to Experion with another OPC Client (INAT) without any issues.
- The error says I lack the privaleges, but if I follow the instructions and change these priviledges via Datasocket Server Manager, it makes no difference.
- We are trying to run this program on a Labview 2011 and Windows 7 system.
- I have tried running this same program on a WinXP computer with Labview 2009. I had to save it for previous versions, but when I run it, it comes back with a 'Generic Error', whatever that means.
Can anyone help me solve this problem and steer me in the right direction.
Kind Regards,

Have any users found a remedy for this issue?
I am having the same problem. I have a very simple network set up where I want to use DS in LabView on one computer (192.168.1.101) to read from an OPC server on another computer (192.168.1.1). The OPC server, DCOM permissions, etc. are all correctly configured, as I can use a third party OPC client to view the server tags and values on the remote PC from my LabView PC.
I am using the "Monitor OPC Items with DataSocket.vi" example VI, just specifying a tag from my existing remote OPC server as an initial test. I can browse to and select the tag on the remote computer that I wish to read in LabView using the "DataSocket Select URL.vi". However, after selecting the tag and passing the URL to the "DataSocket Open" block, I receive Error 1101. (Same occurs if I just directly pass the URL string to the DS Open block.)
I have added "localhost", "everyhost" and "192.168.1.1" to "DefaultReaders", "DefaultWriters", and "Creators" groups in the DataSocket Server Manager. I have stopped and re-started the DataSocket Server, and even rebooted the entire PC, but the error persists.
The specific error text is:
Error 1101 occurred at DataSocket Open
LabVIEW: (Hex 0x44D) Insufficient privileges to read, write, or create an item in the DataSocket Server. Use the DataSocket Server Manager to configure these privileges.
It seems as though this should be an easy fix, given that the OPC server is readily readable by an OPC client. I would appreceate any help, as would mkenneday, if they haven't already solved their issue.
Thanks,

Likely this is an issue related to DCOM configuration. Can you double check tagsrv.exe ("NI Variable Engine" service ) has the correct DCOM configuration talking to the remote OPC Server?

OPC Server does not update data value

Hello,
I have a problem with a program that uses an OPC server to comunicate with a PLC.
It happens randomly, when I update the data, i cannot see any patern, sometimes it happens quickly, sometimes it takes longer...
The data socket is declared like that:
hr = DS_OpenEx ("psp://localhost/Server/Automate.405466", DSConst_WriteAutoUpdate, NULL, NULL, DSConst_EventModel, TIMEOUT_OPC_mSEC, &ecr_MW5465);
And is update like this:
hr = DS_SetDataValue(ecr_MW5465, CAVT_SHORT, l_buf, 1, 0);
The function does not return any error, but the value is not updated server side.
Lookout version is 6.6, the program is made with CVI 8.5.1 and communication is in ethernet modbus. I do not know if further details could be useful.
Thank you.

Fred,
Can you read the value being updated directly from the OPC server? Usually you can just view the values and see if they are updating.
The next thing to check would be to use the shared variable monitor to see if the variables that are bound to the OPC server are updating. It is under Tools >> Shared Variable >> Variable Manager.
Also, when you have the program running, do you get any type of error from reading the shared variable? If you are seeing an error, it would give us a little more insight into what is going on.

Data Refresh Error: We cannot locate a server to load the workbook Data Model.

Hello,
Recently I have developed a PowerBI Report using Excel Workbook with external data source. It refreshes successfully for some days and then starts throwing error on every scheduled refresh as "We cannot locate a server to load the workbook Data
Model."
The workaround solution is to restart the application server which has SQL Server Power Pivot Services Installed which will again work for some more days and again start throwing error.
So, I am looking for permanent fix for it.
Following are additional details about our SP Farm:
No. of front end servers: 2, Application servers:2, DB servers 2 with windows fail over cluster.
PowerPivot Server is installed and configured from App 2 server.

PowerPivot Data Refresh Fails - We cannot locate a server to load the workbook Data Model

Hello,
I have installed sql01\PowerPivot instance of Analysis services on my existing SQL Server and configured it per Configure Power Pivot for SharePoint 2013
http://technet.microsoft.com/en-us/library/dn456880(v=office.15).aspx . I did not install a second Database Engine on the server.
I created an Excel 2013 workbook using the Excel 2013 PowerPivot add-in and saved it to my SharePoint BI Center Document library.
When I try to refresh my workbook, I get 2 errors in the SharePoint log.
http://support.microsoft.com/kb/2756665?wa=wsignin1.0 indicates the sproc is deprecated, but that does not help me fix the issue.

Hi Marcel,
Based on my research, it seems that you have Microsoft SQL Server 2012 PowerPivot for SharePoint 2013 add-in installed on a computer. When you perform a data refresh operation on some PowerPivot workbooks in Microsoft SharePoint 2013, you receive two error
message.
As to the first error, this issue occurs because the Custom Properties on the Excel workbook are not correctly cleared before you set a new serialized schedule. This causes an extra custom property to remain after you set the new schedule. Therefore, the
new schedule fails. To fix this issue, please
install Cumulative Update 9 for SQL Server 2012 SP1.
As to the second error, please
running a repair using PowerPivot configuration wizard for SharePoint 2013. For more information about Troubleshooting PowerPivot Data Refresh, please see:

Passing data b/w applet and apache server

Hi all,
I have an application that runs in the JApplet.I have to pass data b/w server and applet.The
datas are brought from the server using php to the browser and passed to applet using param
tags.
1.Is it possible to set value for the param tag from applet?
2.How to retrieve data from the param tag to the applet in the form of an array.
In the getParameter it is required to specify the param name.
Is it possible to retrieve data from param tag similar to that of getting data from command
line arguments array.

Hi all,

datas are brought from the server using php to the
browser and passed to applet using param
tags.
1.Is it possible to set value for the param tag from
applet?Why do you ever want to do it? It sounds like setting arguments passed to a program's main method from command line after the main method has been invoked. It is possible though to dynamically set any values for any applet params using php before the applet gets loaded to the browser window as you generate an html file on the server side.
2.How to retrieve data from the param tag to the
applet in the form of an array.
In the getParameter it is required to specify the
param name.
Is it possible to retrieve data from param tag similar
to that of getting data from command
line arguments array.You can use some naming/numbering convention for your params. For example settings1, settings2 ... Then you can loop in your code retrieving the values like getParameter("settings" + i) checking to see that it is not null or empty.
However, if you don't want to reload the applet (together with the page) just to get some new data from the server, you can establish a tcp/ip connection as elchaschab recommended.
Cheers!

External Data Refresh Failed. We cannot locate a server to load the workbook Data Model. ThisWorkBookDataModel

Hi All,
I have been trying to fix this for days now. I have tried solutions in many articles but to no avail. So while the error message is something you may have seen may times, I just can't find a solution in my case.
This is the error:
And in text just in case the image isn't viewable:
"External Data Refresh Failed. We cannot locate a server to load the workbook Data Model. We were unable to refresh one or more data connections in this workbook. The following connections failed to refresh: ThisWorkBookDataModel."
What is worse is I have checked the ULS (SharePoint Trace Logs), the Event Viewer Logs and the OWA Logs and I cannot find a specific error that would help pin point the problem.
Excel Workbook
So what am I doing? I have an Excel 2013 workbook and I create an "SQL Server" connection to the AdventureWorksDW database, add a pivot table and a pivot chart, test in in Excel and all works fine.
I save the Excel workbook to SharePoint 2013 and then select "Data" then "Refresh All Connections" and then I get the error in the picture above.
Even more puzzling is I have another Excel workbook that also has pivot tables and pivot charts in the AdventureWorksDW2012Multidimensional cube database in "SQL Analysis Services" and this works fine. Hmmm.
My Environment
My environment is Windows 2008 R2 Server, SharePoint 2013 with the April Service Pack1 and a separate server with OWA2013 SP1. It has an SQL Server 2008 R2 database which has been upgraded to SQL Server 2012.
Data Model Settings
In Excel Services this is set to my server name which is "server-name". As I do not have instances all I can enter is the server name. As this works everywhere else including the workbook outside of SharePoint I do not think this is the problem.
But I could be wrong.
Unattended Account
I have set this up for the PowerPivot Services App and Excel Services App.
ODC Connections in Excel
I have tried all 3 authentication modes, Windows, Secure Store ID and "None" which is the unattended account. I have not tried the other connection types, should I?
Not in WOPI
I am not in WOPI mode.
AD Accounts
I have added permissions in the SharePoint Services and SQL Server, and as they work in Excel outside of SharePoint, I do not think it is a permissions issue. I could be wrong of course, but the problem is in one of SharePoint, OWA, AD,
SQL Server, Excel, and Windows Server.
Isolate the Error
Below is a list of errors I think are relevant but they do not tell me much. The SharePoint logs are not really giving me an error that tells me what to do and where to do it, or even why it cannot refresh, (perhaps not noticeable by the untrained eye).
Problem with SQL Server Not Analysis Services
So my cube database in analysis services works fine in SharePoint/OWA but not the databases in sql server. This is my best clue but I have no idea what it means. Why would it work with an Analysis Services connection but not an "SQL Server" connection?
It Works Outside of SharePoint
If I run the excel worksheet outside of SharePoint all works fine. When inside OWA this is where the refresh error occurs.
Errors from Event Viewer on SharePoint Server using ULS Viewer
"Failed to create an external connection or execute a query. Provider message: There are no servers available or actively being initialized., ConnectionName: , Workbook:"
"Refresh failed for 'ThisWorkbookDataModel' in the workbook 'http://server...'. [Session: 1.V22.26itT0lx8piNFeqtuGVhN214.5.en-US5.en-US36.98c0e158-9113-46e9-850e-edda81d9ed1c1.A1.N User: 0#.w|ad\testuser1]"
And an error in the ULS under the "Data Model" category:
"--> Check Deployment Mode (server-name): Fail (Expected: SharePoint, Actual: Multidimensional)."
This last error, as it turned out, defined the problem concisely, although I was yet to work out what it meant in some detail.

I finally solved this myself (or should I say with the help of several key articles).
The refresh did not work because the database was not in "SharePoint Mode". Yes, SQL Server has modes, 3 of them in fact.
If you installed SharePoint to the default SQL instance which would be called <servername> then you cannot use this default instance for Excel 2013 workbooks in OWA 2013 because the refresh only works if the database is in SharePoint mode.
So what are these 3 modes? The Deployment Mode property in the msmdsrv.ini file has them as:
0 = Multidimensional mode (the default whenever you install SQL Server normally)
1 = PowerPivot for SharePoint mode
2 = Tabular mode mode
How do you know what mode you are in? That's easy, open SQL Studio Manager and connect to all your SQL database engine instances (ignore Analysis Services or SSRS as they are not database engines). If you only have the default instance then that is almost
definately in Multidimensional mode which is the default and what SharePoint installs its databases to.
You must have an instance called <servername>\POWERPIVOT. This instance is the "sharepoint mode" needed, and the default instance name when you install an SQL instance in this mode.
If you don't see <servername>\POWERPIVOT in SQL server then you are not in "sharepoint mode". It is more accurate to say, you do not have an instance that is in sharepoint mode. This is because you cannot simply switch modes on an SQL server.
You have to install a new instance in the required mode, thats the only way.
That's easy enough. Load up the SQL Server setup CD and run setup. Install a brand new instance and select "SQL Server PowerPivot for SharePoint" when you get there in the wizard.
Now you will have the default instance that stores all the SharePoint databases and that is in mode 0, and a new instance called <servername>\POWERPIVOT that is in mode 1. The "<servername>\POWERPIVOT" instance connection is what you
will use for Excel 2013 when rendering in OWA 2013.
You also need to ensure OWA 2013 is not in WOPI mode for Excel worksheets. See the last link below for more information about WOPI.
Next you should go to the Excel Service App in CA and click Data Model Settings and add the <servername>\POWERPIVOT instance.
Then you have to either turn off the firewall on the SQL server machine, or create an inbound rule on the Windows firewall to open the TCP port for the <servername>\POWERPIVOT instance:
1. Start Task Manager and then click Services to get the PID of the MSOLAP$InstanceName.
2. Run netstat –ao –p TCP from the command line to view the TCP port information for that PID.
Finally, you can now create Excel 2013 workbooks that run in OWA without refresh errors, as long as you are connecting to the <servername>\POWERPIVOT instance. Hooray.

'Cannot begin data load. Analytic Server Error(1042006): Network Error

Hi...
I got a error message when I upload data from source file into Planning via IKM SQL to Essbase (data).
Some records are found following errors.
'Cannot begin data load. Analytic Server Error(1042006): Network Error [10061]: Unable To Connect To [localhost:32774]. The client timed out waiting to connect to the Essbase Agent using TCP/IP. Check your network connections. Also please make sure that Server and Port values are correct'
What is this error about? is the commit interval too large? now the value is 1000.

Hi,
You could try the following
1. From the Start menu, click Run.
2. Type regedit and then click OK.
3. In the Registry Editor window, click the following directory:
HKEY_LOCAL_MACHINE\System\CurrentControlSet\Services\Tcpip\Parameters
4. From the Edit menu, click New, DWORD Value.
The new value appears in the list of parameters.
5. Type MaxUserPort and then press Enter.
Double-click MaxUserPort.
6. In the Edit DWORD Value window, do the following:
* Click Decimal.
* Enter 65534.
* Click OK.
7. From the Edit menu, click New, DWORD Value.
The new value appears in the list of parameters.
8. Type TcpTimedWaitDelay and then press Enter.
9. Double-click TcpTimedWaitDelay.
10. In the Edit DWORD Value window, do the following:
* Click Decimal.
* Type 300
* Click OK.
11. Close the Registry Editor window.
12. Reboot essbase server
Let us know how it goes.
Cheers
