LV8 OPC Server Installer

I use Shared Variable Engine as an OPC Server with LV8.
I build an executable (with library deployement), It works on my developpement station (with LV8 installed).
I build an installer (with include Variable Engine and LV8 Runtime Engine).
If I install my application on a PC (Win XP or Win 2000) without LV8, it doesn't work :
Server explorer can see Variable Engine server but can't connect to it (Server not registered !!).
I hope someone can help me.
Than you,

Hi,
You also have to deploy the variables. See the link below for the deploy process for an exe.
How Do I Deploy Network Shared Variables From a Compiled Executable?

Is Shared Variable Engine with LV8 an OPC server ?

Hello
Is the shared variable engine with LV8 an OPC server ?
Does any OPC client can acces to Variable Engine OPC server an read shared variable ?
Can I build an installer and deploy my application with Variable Engine OPC server on other PC without LV8.
Thank you

Hi
You can communicate between an OPC serveur and LV8 and use shared variable. To deploy an LV8 exe application, you must have the run time engine installed on the PC without installing LV8. You can create a setup with LV 8 in which you can integrate the run time engine.

How to install the OPC server with the Application installer

Hi to all,
I had make the datalogging progam by communication the PLC through modbus using the OPC server.
1. I had configer the opc client through project explorer some time it run fine but when i run by next day it can't communicate with OPC server but the OPC server is communicating with the PLC.When i right click on the properties of the opc i/o client in the project exploer and make any change and again run the application it works where the problem is.
2.The second problem is while building the installer who OPC server will installered to my targate PC.Bacuse i had installed the application on the target PC just for testing but OPC server havn't installed even though there is no option for the addition of the OPC server while bulding.
Solved!

HI Serdar,
Thanks for the reply i had seen your example your idea is ok but if i have more then 100 tag and with different data types then where is problem to manage all those tags.
Now what i had done i had put the express vi of create or configer I/O server and give the process name same as file name like opcdemomo and same server name mention in the project explorer and restart and shout down tow and three times it works i havn't get any problem.but that is not the good method.

How to read enumerated values from an OPC server via Datasocket

Hi Labviewers,
I am using LV8.2 and I am trying to find if it is possible to read enumerations from an OPC server via Datasocket, not just the values.
I can successfully read a value for an OPC server via Datasocket and I get a value for example 3, is it possible to get the enumeration/string that corresponds to this value i.e. "Open".
Many thanks in advance
Dimitris

Hi Sarah,
With the input type as variant I get the following response:
1                                     <-This is the current numeric value of the parameter
4 Attribute(s):
   'Quality' -> 192
   'TimeHigh' -> 29861723
   'TimeLow' -> -665408304
   'Timestamp' -> 39.238E+3
With the Input set to         Enum constant I get no values or strings coming back. With the Input set to             Ring constant I just get the numeric value

How can I write to an OPC Server?

Hello!
I was busy a few days with LabVIEW 8 to finish a special task, but now I've got problems to solve the following problem:
I have an OPC connection between a frequency converter and LabVIEW 8. With the example vi's I get the data out of the OPC Server (revolutions per minute).
So I can read data out of the OPC Server, but how can I write? I want to write several voltage values to the OPC Server that the frequency converter gets the required revolutions per minute.
Have you got any ideas? Are there existing example vi's to write data to an OPC Server?
Best regards and Thanks in advance!

So here it is - a little bit modified, but you should get the idea out of it.
If you have questions, I'll try to answer them .

Change what data type data socket requests from OPC server

I suspect this is a foregone conclusion, however just in case; is there a way to make Datasocket request items from an OPC server in a different data type than variant?
I have a server that scales integers (native data type) and offers tham as floating point values, however to get those nice floats the client must request the data in the right type. If the client asks for a variant the server will return the integer value (e.g. 2 instead of 2,36...).
I have not checked whether this is a server behaviour as it must be (according to OPC specs) or if it's just a choice by the vendor (Automated Solutions), but still it may become an obstacle.
Has anyone implemented OPC Client functionality without using Datasocket (and server for that matter)? Any software componants you can recommend?
MTO

Hi Mats
I once found vi's (..\vi.lib\Platform\dataskt.llb) with different read- and write-types. In fact they are all wrapping up the read- & write-variant functions.
I use them to communicate with Siemens OPC-Scout and it works. They make life a little easier .
Hope this helps.

Applicom OPC Server Data Members Identification Help

I am using an Applicom PC104 Profibus DP card with Lookout. I am using the Applicom OPC Server object in Lookout. When I look/try to configure the Profibus slaves - each slave (equipment) has a bunch of modules associated with it (eg. MODULE0-IX0-0 through MODULE0-IX4-8). How do I know which Module contains the information I am looking for (in this case I am looking for an 4-20 mA analog signal from a pH meter). Any help is greatly appreciated. The document that NI has on "useful consideartions..." did not help. Thanks.
Sudhi

1. Which version of Lookout are you using? In an old version of Lookout we might forgot to install the appcyc.dll. That should be in the Lookout folder.
2. Yes, it would be better to contact Applicom, since they install the server, which has to be configured first, before you can connect with a client (Lookout). To test the server configuration you might use as well our OPC Test Client (Server Explorer, which is installed as well with the latest Lookout 5.0)
Actually, I have just some minor experience with the PCI-1500PFB which however uses the Applicom 3.4 driver and not the ApplicomIO. Even though, I don't know for sure if the native Lookout applicom.cbx would work with the ApplicomIO. But I assume that underneath you just need to configure
the PC104PFB with any kind of tool (set EquID, ChanID, Protocol...) and the initialisation has to be started at PC startup.
I've attached the appcyc.dll, just in case you wouldn't find it on your installation.
Feel free to add any experience you will make. Other DevZone users might find it helpful.
Hope this helps.

Configuration frequence acquisition opc server

Bonjour,
J'installe actuellement un scanner 2D. Il se déplace grâce à un automate que je commande via l'opc server et LabVIEW.
J'ai besoin de la position en temps réel de l'automate pour savoir à quel endroit précisément mes mesures ont été faites. Actuellement la fréquence de rapatriement des données de position de l’automate semble être à 1Hz. J’ai besoin que ce soit beaucoup plus souvent. Je sais que l’automate connaît sa position en temps réel mais je n’arrive pas à l’obtenir à plus de 1Hz dans mon programme LabVIEW.
Je pense qu’il y a des paramètres à régler dans la configuration de l’opc server pour me permettre d’obtenir la position de l’automate à une fréquence bien plus élevée. Après de multiples essaie je n’ai toujours pas trouvé comment faire. Quelqu’un aurait-il la réponse ?
Résolu !
Accéder à la solution.

Bonjour Sydenel,
Tel que je le comprend, il semble qu'il est possible de définir plusieurs "Scan mode" dans NI OPC Server (Click droit sur le device-->Propriétés-->Scan Mode)
Par defaut c'est la première option qui est choisie, est le scan rate dependra de la frequence de demande de la valeur par le client.
Dans le lien suivant http://www.ni.com/tutorial/7450/en/, vous avez un exemple de mise en oeuvre. Dans ce cas, je pense donc qu'il s'agit du vi timming qui va régler la fréquence
de mise à jour de la variable en question.

OPC Server with LV 8.20

Hello!
I have a LV8.20 application that will eventually reside on a PC as an executable.
I have a requirement to communicate 3 different pieces of DATA to a plant SCADA system which is running an OPC Client application. I originally started to investigate the solution to this problem and came across the DSC module, which I figured I would use to put an OPC Server in the middle that I would publish my data to, and then the SCADA system OPC client could pick up the data.
Someone on the Info-Labview forums told me that the new LV8.20 Shared Variable engine can act as an OPC server 'right out of the box'. Is this true?
I have been able on your website to determine that DAQMX can be an OPC server, but I am not using any DAQ hardware.
Do I have an OPC server with LV 8.20 somehow, or do I have to buy one so that I can publish my info to an OPC client on the same network?
Thanks,
Wes

Wait a minute. Now I'm confused....
I was trying to use Labview as a OPC Server and then have a Controllogics PLC connect to it. At first the NI phone rep (app engineer) told me that it could be done with the Industrial Automations OPC Server. But then after further investigation (on my part and then by calling NI back) I found out that it's not supported. But if I can create a OPC Server with Shared Variables can't I then connect to that Server with the PLC as well?
Thanks for the clarification,
Matt

Application not reading data from opc server?

Hello,
I have developed an application that reads and writes information from and to an OPC server (Phoenix Contact), and for this have used the DSC Module and labview 2014. When I run it from LabView, it works perfectly. I want to deploy it to another computer and for that I have created an Installer that includes the source files, the labview runtime, the DSC runtime, ni distributed manager 2014, and the variable engine.
When I install my application to the other computer, it doesn't "see" the data from opc, although the data reaches the computer (I've checked). Can you please help me with some suggestions regarding this problem? Am I missing something?
Thank you.

You don't have NI OPC Servers on either computer? That's generally the software required to talk directly to an OPC Server. On the computer where things are working, try going to your start menu and searching for NI License Manager. See if there is a listing for NI OPC Servers. I'd expect it to be activated to a single driver.
On the deployment PC, make the same check. I'd expect it to be missing.
The distributed manager is just a way to view the shared variables you have on the system and interact with them. DSC works with NI OPC Servers to display your tags. The RTE is needed on the deployment PC. But, I'd also expect you to need a way to convert the tag into the shared variable you're seeing in both the DSC RTE and distributed manager.
Using the Phoenix utility shows the computer is connected to the same network. But, it doesn't show the tags are reaching LabVIEW. You're generally better off starting with the Quick OPC Client as this will use similar methods that LabVIEW will.

SharePoint Server 2013 single server installation licenses and system requirements

We are thinking of setting up a SharePoint Server 2013 for the following features to be accessed by our test team (<100 users)
Our requirements are as follows -
Total user access <100 users(starts with 50 and may be go upto 100)
Mainly Access to TeamSite(Document library), WiKi, BI reports view(SSRS Reports integration)
We have a Visual Studio Ultimate license that covers SQL Server 2012 and Share Point server 2013.
We have also got a Amazon EC2 machine access to create a Xlarge box with Microsoft recommended Cores, Memory, storage for SINGLE INSTALLATION of SharePoint Server 2013 and SQL server database on Windows Server 2012
My queries are as follows
Are the licenses above sufficient to go ahead with setting up the SP Server? or do i need any other licenses ?
I would like to create local LDAP in amazon without connecting to the company active directory. Would this be possible? We have users from other locations(different countries) providing services to our company and we would like them to access this portal
to share and access docuemnts without any network issue etc..
Are there any known firewall issues with EC2 machines for share point deployment
System requirements for single server installation (with or without BI reports)
Please note this implementation is only for internal use by the test team and is not critical. Not a production implementation.
Is there any better solution?
Much appreciate your help
Thanks
Vara

MSDN subscription licenses for SharePoint aren't, as far as i know, for use as production devices. This means that whilst you can use it for testing and development you can't use that license for the SharePoint server that you'll all be using.
As such I think you will need to buy a SharePoint 2013 server license. The same goes for SQL, Windows etc.
There is also the question of user licenses, ie. CALs. I don't remember if those come included as part of an MSDN subscription.
2) Possibly. As long as Amazon can host a domain for you it should be possible.
3) Pass. Microsoft prefer you to use Azure and most of my training and experience is with that.
4) High. 4 cores, 24GB of RAM minimum.
http://technet.microsoft.com/en-us/library/cc262485.aspx#hwforwebserver
You'll either need a 2XLarge or a memory orientated box, in which case you won't have much storage space.
Internal team infrastructure is still important. If you're using it enough to make it worth having then you need it there and running.
Have you considered using Office 365?

SAP DMS server installation Query

Guys,
I would like to share my plans on DMS server installation under DEV,Quality,prod stage and requesting you all to validate and send me any comments if I am wrong anywhere.
-        We have 1 external DMS server of (250Gb capacity)
-     We are now in realization phase, As we know that we have 3 servers namly Development, quality and production server.
-     In Development Server we do Baseline DMS customization
-     In Quality server we do Integration testing
-     There will be as external computer with harddisk capacity of 80 GB,I will Install Content server CD and make that 80GB hard disk as content server for storing the documents, create content repository and store the documents which are to be tested under both development and quality server stage(Note : we can use SAP database for both testing purpose but If we load huge data there,it will slowdown the server drastically)
-     During the production server install the DMS server (250 gb) and define the content repository config under production server and start storing all the fresh document
-     Note: Since the tested documents are stored in local PC we can avoid all the tested documents under quality stage only,once the DMS server is installaed in production server we can freshly load the documents.
-     Note: I knew I have to install twice the Content server cd(once with 80 GB local hard disk and later with External DMS server)
This is how I planned, I request you to highlight the pain areas by this method else give me the confidence of how I planned?
I appreciate for immediate solution; also how does Kpro comes into picture here.
Points will be rewarded for sure.
Regards,
Murali.S
DMS consultant

Hi Murali,
As per my understanding you want to keep a Temporary Content Server for your Dev & QA system but a full fledge 250GB Content server for Production.
This is a Good method you are following, i.e. when you go for production you will not have any junk data, you will be loading only fresh data (originals) into it.
There is nothing harm or pain in doing this, only thing is you have re-configure the Content Repository and Category in Production System (SAP).
Your Basis person has to open Production System for doing this Settings (Defining Content Repository and Content Category with Port, HTTP, etc)
Document Area to be ensured in each client at any point of time, Physical machine, IP address, Port etc.
You can maintain a Excel sheet with a following Columns:
<b>Client, Content Category, Content Repository, Document Area, Physical Machine, IP Address, Port.</b>
For Transaction OACT & OAC0.
Rest your method is fantastic.
Best Regards

New Server Installation, now client computers can't connect to services. Where to go from here?

Hello.
I recently had to setup a new Mac Mini Server (Mavericks). We had one previously but one of the raided hard drives failed. No backup.
Our office of 6 Apple MacBook Pros used to connect to all file sharing and calendar services, easily.
On the new Server installation, I added the same users with the same passwords etc. The client computers cannot access calendars, file sharing etc. On the clients, I have opened up System Preferences > Users & Groups > Login Options > Network Account Server and added the FQDN of the server, but I get an error ' Unable to add server. Connection failed to the directory server. (2100) '
2 of the clients are on Mountain Lion. The rest are on the latest Mavericks.
I'm a bit lost on where to go from here and would appreciate your help before I wipe everything and start from scratch.
Thanks.

Hi Strontium90
Ha! There was a time machine backup, but we had a storm here which rendered it and the server useless. We are such a small team without an 'IT' guy, apart form me as I have a vague interest in all things Apple.
What is your DNS name space?
Do you need the name here?
Do the servers and the client agree on this name?
Not sure what you mean. The domain name works as when I type it into a web browser, I can see the 'Welcome to Server' page.
Did you enable an Open Directory Master?
Yes. Open Directory is running.
Did you grant the users/group access to the service you are offering?
Yes. All services are checked for each user.
Make sure the user/group is permitted to access your enabled services.
All allowed, too.
Oh, and implement a backup strategy
Will do, once I sort out this problem. Time Machine and off-site, I think.

Start multiple domains simultaneously on 1 Weblogic server installation?

Is it okay to start and run multiple domains simultaneously. Better yet, when having multiple domains on 1 WLS server, should each domain have a different port number in order to be run simultaneously?
Here's my scenario - I installed Oracle Business Intellgence, which by default installs and configures WLS server for certain Business Intelligence applications (BI Publisher). This instance was running fine and good and still is.
Then I had another application, Oracle Data Integrator, which has a Console piece that requires a domain on WLS. So instead of modifying the existing domain for Oracle Business Intelligence, I created a new domain via the Configuration Wizard and selected those components for Oracle Data Integrator.
therefore current domains:
...\domains\bifoundation_domain --> installed automatically as part of Oracle Business Intelligence
...\domains\odi11g --> I created this domain after I
Now I have 2 domains under 1 WLS Server (windows 7 64bit), but if I startWeblogic.cmd for the bifoundation_domain, and I startWeblogic.cmd for the odi11g...then only the components for the bifoundation_domain become available via the WLS Console.
Questions:
- Can I run both domains simultaneously?
- Should I have modified the bifoundation_domain to include Oracle Data Integrator component; therefore only having 1 domain but having everything run under that domain?
- Does the Port for each domain matter? both bifounddation_domain and odi11g domain use ports 7001
Are there any other considerations? Thanks much.

Hi,
It is perfectly OK to run multiple domains on a single Weblogic server installation. Only constraint would be you have enough capacity available on your server to start multiple instances.
Things to note is, if your domain1 is running on listen address : port { localhost : 7001 } then your other domain should be configured on a different port say {localhost : 8001 }. If you want both domain to run on same port then go for virtual IP's to be plumbed on your physical network interface and configure as,
domain1 - { ip1 : 7001 }
domain2 - { ip2 : 7001 }
this way you will can access both domain admin console on same port.
Remember, Weblogic resources cannot be shared between domain, however a single nodemanager will be enough to monitor both the domains.

Problems using Modbus TCP accessed by NI OPC Server

Hi there,
i'm using NI OPC-Server to access a measurement module. The buildup is quite easy, my system with NI OPC, a modbus gate and there the module connected with RS485.
There's a thermocouple to provide me some sample data.
But there's the point. I know, my data is in the Holding Registers and I can access them, but every data type I'm trying doesn't bring my my data out, just any other (sometimes Huge with e34, sometimes very small like e-13...) sorts, i can't understand.
The type provided by the module should be single precision.
In Lookout the address used to be is 41000 in Labview it's just 999 and in the "target" OPC-Server I get some values at 401000 but not useful.
I also get the same results accessing 301000 in different types.
Read/Write or Read Only is equal.
I've tried to tell my OPC that the values are Strings, Floats, Words, BCD and all other possible ways OPC offers me, but nothing results in a usable temperature.
I hope I missed something and you could suggest it.
Cateros
Solved!
Go to Solution.

Thanks for your reply.
in LabVIEW I'm using the provided Modbus Libraries. If I unbundle the Holding registers, my value appears at Holding Register [0], I'm type casting it to single and get the sample temperature. (Address 999->unbundle->typecast->value)
In NI OPC, I'm reading ( [depends on zero based addressing] 300999/301000 equal to 400999/401000) an already typecasted Holding Register [1] compared to LabVIEW (and the value changes in the second or third digit behind the comma and they are changing at the same time). Data type in the tag is float.
Another disturbing thing is even if I change in the options "using zero-based addressing in registers" my value does not change.
If I'm reading two addresses close to each other (as you mentioned 401000-401001) I'm getting an unknown data type and no results. How do I read multiple addresses without such errors? And how do I specify a special register to read?
Scaling should not be the problem, I am having three ways to get my value (FTP-Server on the gate (just a *.dat file with correct type), software the the module manufacturer (while measuring and configuring the module) and LabVIEW(as can be seen above)) .
Sadly, I have not found any useable modbus documentation about the module (just it can use modbus, you have the registers, you could read/write and fine)
When I'm adding a second couple to the module, in LabVIEW Values in Holding Register [2] and Holding Register [3] appear and are changing.
