Help Needed in establishing connection between Kepware OPC server and UDS 4

Hi All,
I am in the process of establishing connection between Kepware OPC server and UDS 4.0,
Can anyone guide me through the process of configuring UDS 4.0 to establish conection with the Kepware.
Any standard documentation on UDS 4.0 will be of great help.
Thanks in advance,
Shyam

HI Rajesh,
I am creating OPC DA instance and when i try to browse for the OPC servers available in the machine, the list is blank. i am not able to view any OPC servers.
Actuallt the Kepware OPC server and UDS are installed in the same machine.
Can you plz through some ligh on this

Do I need rslinks and a kepware opc server

To get 12 words from an Allen Bradley 1500, over an ethernet link, from an existing Labview 6.1 application, will I need an RSLinks sever and an OPC server such as Kepware? Or one or the other

kayr,
RSLinx would be straighforward using DataSocket. We use DataSocket quite often to communicate with AB hardware through RSLinx. You could also communicate directly to the AB hardware using some of the tools available at this site.

Connectivity loss between PLC and Kepware

Hi Experts,
I m working on SAP PCo and PLC connectivity using Kepware.
I m trying to find out ways to find connectivity loss between
1) PLC and kepware
2) kepware and PCo
For 2nd approch,if connectivity loss is there then PCo instance will go in error state and using remote monitoring we can get alert.
But m not able to find any way for 1st approch.
If PLC connection lost then only tag quality in kepware is bad.
Is there any way in PCo expression editor to check tag quality so that i can trigger MII transaction?
Thanks in advance.
Regards,
Neha

To add to Hubrisnsx's comment ... are you provisioned Ethernet or MoCA for the WAN connection?
Edit: Never mind, I see in the first post you said MoCA. So, if the MoCA channel is staying up, then it sounds like it might be something inside the ONT.
Keep in mind that while some Verizon folks do drop by these forums from time to time, that this is primarily are user to user forum where customers can help one another.

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

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.

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.

Kepware opc server

How can I configure KEPware OPC Server with Labview 7.1 or Labview 8.5 DSC.
I would appriciate, if you guys give the information link or tutorial link.
Thanks

I haven't done this with version 8.5 yet. It will use the shared variable to link to an OPC server.
http://search.ni.com/nisearch/main/p/sb/navsRel?q=shared+variable+dsc+&x=16&y=5
Version 7.1 uses the tag engine to connect with an opc server.
The two labview versions use different methods to talk with an opc server.
Which labview version do you really want to use??

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?
Cheers

Why does reindex documents at Server in the Configuration Manager break the help system?

Background:
So, I have a nice hosted help system on Server 9. I'm using the Access database since it's a light load project. It works OK. All admin features work OK (except groups and users bug, unrelated), including reports on search and usage. So, I have been having a devil of a time making a particular search term work in my project: UTS. It's an acronym for a system at my work, and it's important that users be able to search on it. UTS is in several Heading 1s. It's not in the stop list as a typo. Just to be sure, I deleted the whole stop list. I added "UTS" as a topic keyword. It still refuses to find any results. Also, I've noticed some other peculiarities with search: the "context" displayed below the search result is supposed to show the word you searched for in its context, but it never does in my search results. It just shows the first words of the document it's listed as a hit in search. The search is not bad, but these two bugs were odd enough to me to start rooting around for solutions.
So, I run Server 9 on Windows Server 2008 R2 with Tomcat 7 and JDK 7u17.
The problem:
I noticed in all the Server documentation that Adobe crows about the wonderful full text search powered by Lucene, and how it's checked "on" by default in all contexts. It's not in mine. When I check "reindex documents at server," it breaks the project. Literally--Server can't find the project anymore, web calls come back with no answer. Uncheck the box, A-OK. So, why is this wonderful search technology not available to me? Is it because it's not available when using default Access? Or is something else going on here?
many thanks in advance.

The problem is that my data collection software (VisualPlant by EMT) is unable to browse to the National Instruments.LookoutOPCServer. When I added an Identification category to the registry entry for the lookout OPC server I was able to connect but with some odd behavior. My setup is:
2 machines each running Win NT4 SP6a. One machine is running Lookout as well as several other OPC servers. The other is running my data collection software. I am able to connect to lookout using several client apps on my data collection machine (Kepware's Quick Client, and Matrikon's Client), however my data collection software (VisualPlant) cannot see Lookout. Using the NI server explorer and viewing the properties of all of my OPC servers I noticed that Lookout was the on
ly one listed that did not have a CatID. By modifying the registry and adding the ID's listed in my original note I was able to connect using VisualPlant, however this exibited some odd behavior. It appears that adding this setting prevents multiple OPC connections to Lookout. If you have any suggestions I would greatly appreciate it.
Thanks.

Is there a way to replace tags on import rather than create duplicates??

I use the tag engine to connect with the KEPWARE OPC server program and at times I want to change how the tags are located inside KEPWARE but keep the same tagnames inside LABVIEW. I export the .scf file and modify it inside EXCEL. When I import it again it will create duplicate tagnames. When you have 4000-8000 tags, it can take awhile to delete the duplicates. It would be great if we could replace the existing tag name data. Maybe I should be creating a vi to modify the properties of individual tags instead. How does anyone else work around this issue??

I would export all of the tags and then modify the ones that need to be modified. Then, before I import them, I would create a new scf file. This way there are no duplicates.

I would like to use DasyLab for a research project with Siemens PLC

I would like to use DasyLab with Siemens PLC Simatic S7-300. Which OPC Server shall I use?
I would like a manual for connecting DasyLab via OPC server to the PLC if it is possible.
Could I use NI OPC Servers which are compatible with LabView?
Thank you for your help

I believe that Siemens has an OPC server that you can purchase.
KepWare has the KepServer and drivers for Siemens www.kepware.com.
DASYLab has the Help menu with the instructions for the OPC DA modules. It's straightforward - configure the OPC server with the necessary drivers and connections (tags). Update rates are in milliseconds, for example, 100 ms is typical. You need to know your device and driver, to determine data types.
Once configured, KepServer has an OPC quick client to allow you to test your settings.
Then, add the OPC DA module to DASYLab, connect to the server, and select the tags to read or write.
Note that it's simple to set up on a single computer - to set up on multiple computers requires assistance from your It team to correctly configure the DCOM permissions. That's specific to the OPC server.

PCO Query: tag not found

Hi,
I am writing values to a datablock on a PLC using SAP PCO and OPC as middleware.
It is working for all tags in the datablock except for 2.
This is a screenshot of both tags in the OPC Quick client (I am using Kepware OPC server).
I can read and write the tags from here.
I have created a small test. In the MII workbench I created a PCO Query.
Next I dragged the two tags from the tag browser on the left, to the right.
For both tags I filled in a value.
When I execute the query I get following error messages.
M1 Order Dispatch/OrderQuantityTarget: Tag PoederMagazijn/ATS PLC/M1 Order Dispatch/OrderQuantityTarget not found.
M1 Order Dispatch/OrderQuantityConfirmed: Tag PoederMagazijn/ATS PLC/M1 Order Dispatch/OrderQuantityConfirmed not found.
Any other tags work fine.
Thank you for your time.

Hi Philippe,
I tested a similar tag name in Kepware with the Simulator device as I do not have a Siemens hardware connection at present. I was able to read and write DWord tags without issues on these versions:
Kepware V5.15.585.0
MII 14.0 SP5 Patch 15
PCo 2.305.2141.1051 (Patch 3)
Additional question: What is the Agent Instance Tag Query Cache Mode set for?
Regards, Steve

Unusual issue with tag engine and BELKIN USB to Ethernet adapter??

I have an .scf file with 72 tags and several tag groups in it. If I open the tag engine without the usb adapter, I can read the tag group names with the get group list.vi. The tag group names are listed in black letters when wired to an indicator. When I plug in the usb ethernet adapter, immediately the group tag names are greyed out in the indicator without even running the vi. If I put a tag constant on the block diagram and try to select a tag name with the pointer, no tagnames pop up. It worked yesterday and my IT. department sent down a shockwave and flash5 update download when I booted up this morning. anyone have any ideas??

I am still seeing the tag groups disappear when I start the tag engine on labview7.0. I have several other programs running at the same time, KEPWARE, PROWORX NXT, USB to ethernet adapter. This is on a win2000 machine.

Unable to access only Read Write addresses of AB Micrologix 1400 PLC using NI DSC and NI OPC server

Hi,
I have been using NI DSC and OPC servers (NI and Kepware) to communicate with Allen Bradley Micrologix 1400 PLC (1766-L32BXB). Recently at one site I found that I could access Process values from the PLC correctly (Read Only tags) but could not access the Read Write Tags at all. The latter are addresses to which it should be possible to write Set (i.e., references) values from MMI or PC software. I am able to do so from the MMI not from the PC software. I get communication error message on the MMI and PC, mentioning the PLC address being accessed (e.g. N7:0).
Support from the supplier is not available. Hence can anyone let me know if ladder logic could have been written to prevent PC software based access of Read/write addresses (N7:0 to 9 in this case), while permitting access to Read only addresses? Is the problem at the PLC end or OPC server end? Is there a way to get around this?
Thanks in advance.

The OPC Server cannot force Outputs so if th registers in question are the outputs of ladder rungs you cannot write to them via the server. The controller will accept the write from the server but will not execute the write. In some cases the server event log will post an error if it is the PLC. Do you get errors when you try to write and if so what are the posted error messages.
