• Can not find driver for CompactLogix L32E in OPC Server OR

  Anyone know how to contact the CompactLogix L32E Lookout 6.5.

  It doesn't seem to be a driver for it in the OPC server from OR.  Can someone point me in the right direction.

  I thought that the 5300 ENI:CompactLogix would work, but it does not work.

  Thanks to the folks at Kepware. I was able to get this working for CompactLogix L32E.

  Step 1: In the OPC Server OR create a new channel. The channel name can be anything you want.

  Step 2: Device driver will be ControlLogix Ethernet.  You can also enable diagnostics if you want.

  Step 3: Network adapter. I used default.

  Step 4: Write only the latest values.  Service at 10. (These are the default settings and are recommended.)

  Step 5: Finish new channels configuration

  Step 6: Click the icon to create the new device

  Step 7: The name of the device can be selected.

  Step 8: Select model of device in this case CompactLogix 5300

  Step 9: Device for me ID been XXX.XXX.XXX.XXX, 1, 0 IP address (note the 1 redirects the path at the bottom of basket.) 0 to the location where the processor is)

  Step 9: Device synchronization.  Leave the default values.

  Step 10: Automatic demotion leave unchecked.

  Step 11: Leave default values do not generate start remove create and enable the subgroups

  Step 12: Port and watchdogs with default settings

  Step 13: Options of the project leave default. (In my case, I've changed to short because that's what most of my tags was)

  Step 14: Create tagname of the device.

  Step 14: Finishing Device setup.

  You now have two options.

  Option 1: Start creating labels according to your needs. (This is what I did)

  Option 2: Newly created device right click and select property.  Then select the database creation and click auto create.

  Go to the belvedere and create the new driver.

  Select Client OPC

  The server name will be on the menu drop down. National Instruments: NIOPCServers

  Click OK

  You must be done and smiling.

• connect a controller without opc Server

  Hi, I can connect a controller for labview 7.1 (to send and read the data) without an opc server, using only one cable rs232 of the plc to the pc.

  Hi syd_b,

  Yes, VISA read and write operations are essentially functions, you need to use. Please refer to the shipping of serial communication examples. Again I have not the slightest idea how complex the DF-1 protocol is to implement. It could be a much better deal to buy an OPC server or a ready to use the library instead of reinventing the wheel, but of course it depends on your personal situation.

  Kind regards

• DSC: Connection to the 3rd party OPC Server

  I had this work with LabVIEW 2011 and Win XP...  After update I can't make it work...   Now with LabVIEW 2012 and Win 7, the server is now upgraded to Win 7 system.

  I'm reading a commercial server OPC of Yokogawa variables.  I can connect to the server.  I can see the variables and create a related shared variable.  But when I access the variable fails.

  Dave,

  My problem is very basic.  Go to the administrator in the 'control panel' the instructions say.  It does not exist in Windows 7.  I'm stuck.  Here is the complete procedure as given by the very useful Dylan Caswell.

  Here are the instructions for Windows 7 (I'll put this on the forum so that others can see or change the KB if it works)

  1. press on the Start button and Type: Component Services
  2. click on "Component Services" under programs
  3. in the left Section of "Component Services" expand: ' Component Services > computers > my computer > DCOM Config.

  
  4. search for the name of your OPC Server (in your case should be in the sense of: "Yokogawa Exaopc Data Access Server")
  4A (not sure if this is necessary, but I also repeated for the other server "Yokogawa Exaopc data access server OPC Link1")
  5. right click and select properties of your OPC Server

  6. click on the identity of the Properties window tab
  7. Select "interactive user."
  8. click OK, and then restart the computer

  This does not solve the problem, so I went to the second stage.

  If this does not work, let's try the other method, as described in the KB but for Windows 7:

  1. press on the Start button and Type: Services
  2. Select 'Services' under programs
  3. in the right part of the window, sort by name by clicking on the 'Name' column, and then select: NEITHER engine Variable
  4. right click NI Variable engine and go to properties
  5. Select the log tab, click this account:
  6. Select an account that is an administrator
  7. Select OK and restart the computer.

  There is a 'right click' option to stop and start the service.  I don't reboot but simply stopped the service, numbered 5 and restarted the service.

  Immediately my VI running began to show valid numbers!

• Connecting a PLC Siemens S7-300 NI OPC Server

  The project of memory Bachelor last year, I have two other are involved, I was instructed to implement a HMI/SCADA system to control the level and flow in several water storage tanks. This must be done locally via a "operator panel" and also remotely via Internet through a webbrowser. These storage tanks and control system is placed on a wheeled demonstration model, so it can be used in classrooms and auditoriums. Therefore, I have a Siemens PLC S7-300 and the latest edition of LabVIEW (ed. professional 2009) available to me. To create an HMI system, we will also acquire the DSC module OR that she would have everything we need (OR OCP is included?).

  Since it is a project of the bachelor and the school is mainly to pay for everything, we are on a pretty strict budget. This means that we have not opted for a solution for the "operator panel" because this would be depends on the way in which the Group and the PLC interfaces. We would like to do for the sake of simplicity is to use commercial laptop computer with touchscreen ability thus having a solution 'all-in-one' low cost, both for the local input & control and ability to web publishing. Now, most of the computers today do not serial agrees, but rather USB ports.

  On the Web server under the title OPC Device Connectivity page, it is specifically indicated "Siemens HMI adapter for S7-300/400 via Serial with HMI adapter". I guess this means the following Siemens unit: https://support.automation.siemens.com/WW/llisapi.dll/csfetch/8774263/hmi_adapter_x.pdf?func=cslib.c... (6ES7 972-0CA1X-0XA0).

  This means that the server of the OCP can only use a connecting series via the HMI adapter for S7-300 directly? Is it not possible to use a USB adapter series without driver with the HMI, or for example the Siemens CP5711 MPI adapter USB adapter? If it is not possible to use a USB based solution, we would have to use an old desktop PC with a Compote series or an additional PCI card and it's something that we would like to avoid.

  Any help on this would be much appreciated.

  -DanJack, NUC Norway

  Through 3rd party providers that I discovered that pilots of NI OPC for Siemens S7-300 Server supports ONLY in legacy communication RS232, no USB connectivity support any. You can only use the MPI for adapter RS232 or HMI for RS232 adapter.

• OPC will not AB L32E - write Will Read

  OPC will not AB L32E - write Will Read.

  I was able to put in place an OPC server using OPC server, OR by using the ControlLogix Ethernet driver for the 1769-L32E AB PLC.

  All tags are visible. The lookout 6.7.1 see data in real time, but everything that I write too, never appears in the PLC.

  Using the OPCclient at Lookout. There is no alarm, another that a value has been adjusted by the direct user...

  There is no error of comm.

  I just bought this software last month.

  The OPC Server NOR, events, no error.

  Thank you.

  Dave

  I had figured it out. The address may be a little different than Lookout Direct.

• cRIO communication as a PLC with NOR-OPC-Server

  Hello

  I have the task to implement communication between multiple cRIO and NOR-OPC-server. The OPC OR server should act as a data manager for a complex interface.

  I tried the NO-OPC Server and I managed to communicate with the server OPC-NOR as OPC-Client in Windows using a server IO and shared Variables. But the task is to do it on a cRIO. I tried to open a data from a cRIO socket connection to the NOR-OPC-server using a specific URL by using "DataSocket select URL.vi." But as long I do not activate the simulation in the OPC Server - OR-I get errors on the data socket connection opening. If I activate the simulation, which is not the solution, I can write data without error, but the quick OR-OPC-Server Client sees no change for the data label.

  I have the feeling that I am not a good way to get this working. Is there anyone with experience with this? Is data taken one possible at all? It is possible at all? I have to put in place a cRIO-OPC-driver?

  Thank you.

  Hello

• Problems using Modbus TCP accessible by NI OPC Server

  Hello

  I use OPC OR server to access a module of measure. The accumulation is pretty easy, my system with NI OPC, modbus door and the module connected with RS485.

  There is a thermocouple to provide me with some examples of data.

  But there is the point. I know, my data is in the records to be kept and I can access, but each type of data, I'm train does not bring my outgoing, any other (sometimes huge with e34, sometimes very small as e - 13...) my data sort, I do not understand.

  The type provided by the module must be single precision.

  The address used to be lookout is 41000 Labview in is just 999 and in the 'target' - OPC Server I get some values to 401000 but not useful.

  I also get the same results to access the 301000 into different types.

  Read/write or read-only is equal.

  I tried to tell my mutual FUND values are strings, floats, words, BCD, and all other possible means what mutual FUNDS offered to me, but nothing results in a usable temperature.

  I hope that I missed something and it might suggest.

  Cateros

  Finally, the issue is resolved.

  We tried a few others setting for the device in NI OPC modbus Modbus function 06 use simple written record. Using the Modbus 05 functions for single coil written and use default Modbus byte order.

  These parameters were not default and I tried some combinations but bad not these.

  As the tag data type, we tried anyway and got the content of the Register Holding data [0].

  Now it works, and the value is the casting of Holding register [0] and [1] Holding and I got the temperature.

  Already you are quite right, thanks again.

• OPC Server run only a few Variables - DSC

  Hello

  System: Win7, LabView2010 SP1, DSC

  I have a (Bachmann M1) SPS connected to the PC via an OPC server. I have a draft LabView 100 Variables. These Variables a figure on a HyperTrend a saved in an ASCII file. It works very well, most of the time

  But after a restart of the SPS it gives reading tower, about 25% of the Variables. In the control of the OPC tool, I can see that the OPC server is running and all Variables are very well. I also see in the NOR-DSM. Here, I can see that the value of the Variables is "NAN". After a restart of the process library, it works fine until the next reboot of the SPS.

  I have this combination of Hard - and Software component (SPS - OPC - PC) which works well on 10 other Test applications. Also after a reboot of the SPS. I also run the same software. I only change the address of the OPC Server and must import the reactive power. But the rest is the same.

  If anbody else have the same problem and maybe a solution for this problem?

  THX Martin

  Hi Martin,

  The LabVIEW Datalogging and Supervisory Control (DSC) Module offers servers OPC Client IO can communicate with any server that implements the OPC Foundation OPC server interface, which is a standard based on Microsoft COM.

  You should check the DCOM configuration for a local OPC server before connect you to a server OPC Client IO on the OPC server. National Instruments recommends configuring the server OPC runs with an identity of the interactive user.

• 2011 OPC Server V5.5 in Lookout 6.6

  Hello

  I use Lookout 6.6 with the OPC 2011 V5.5 server.

  The OR - the server is accessible via Lookout and the integrated OPC Quick Client. But if I use another Client such as the OPC data-spy or PROFILAB,

  the server is not accessible, the name of the server appears in the list, but is not accessible. Other OPC servers installed on my PC are accessible by each customer. Do I need to have a special license for the OPC Server OR provided with the software of Lookout 6.6? I am using Windows 7 32-bit edition.

  Thank you for all the advice

  Greetings

  Claude

  Mike's right. We don't allow connection to the OPC Server OR the other OPC clients.

• Application built with an OPC Server

  Hello everyone
  I build the application on the development using wich S7 computer - connected to the OPC Server 1200
  and I want to build the application to run the VI on another PC without installing labview, however when I finished to build the application with the installer and install the application on another PC it cannot connect to shared variables so I installed an opc Server ON this machine and add the server to the software mutual FUND that contains tags and variables
  but it is not also connect to the opc Server
  So how do you run the application on another PC with an opc Server!
  How the VI to use a specific opc server on this PC with no labview?

  Hello

  What do you call the OPC Server? You are creating a mutual FUND of LabVIEW client and linking to the shared variable? If this is the case while you use the LabVIEW DSC module and it works very well in the development environment.

  However, every time that you deploy (creation of executable or installer) a VI using DSC module, you must have a license to run on each computer that runs the executable file. http://sine.NI.com/NIPs/CDs/view/p/lang/en/NID/210561

  the alternative would be to use the socket api in LabVIEW to call the server.the attached VI OR OPC illustrates how.

  I hope this helps!

• Is there a maximum number of clients to one opc Server opc

  I created a server using this tutorial:

  http://digital.NI.com/public.nsf/allkb/CC9CDD577F041786862572120061EB5A

  I am noto using NI OPC Server (I think) and I'm using DSC noto (obviously)

  Is there a maximum number of customers mutual funds for an opc server created in this way?

  I have LabVIEW 2009 now but the main code was written in LabVIEW 8.6.

  Thank you

  OLA.

  Neste caso, a limitacao para a Criação customers also estara watch a ability of sua rede e MATERIAL, or seja, na o maximo para um indefinido e OPC Server clients number theory.

  E claro what puder use OPC server o senhor NOR e o DSC module, a confibilidade e estabilidade of sua aumentarao, POI software esses size adicionam tools ao LabVIEW as facilitam a programcao of codes para este projeto tipo.

  Atenciosamente.

  Hello

  In this case, the maximum number of clients t connect to an OPC server is limited by the configuration of the network and equipment, in other words, in theory, this maximum number is undefined.

  It is also true that if you can use the OPC server of NOR and the DSC Module, your application reliability and stability increases, because this two software add tools in LabVIEW that facilitate deploying code for this kind of project.

  Sincerely.

• Photosmart 7520: Scan to email - server connection error

  Apologies for another post on this subject, I worked my way through the various fixes but none have worked.

  Scan to e-mail worked very well - we use it quite regularly. Then, about 3 or 4 weeks, we got our first message "error server connection." I'm not aware of nothing to bud in our home network, where we use the printer.

  A moden is connected to an Airport Extreme (82.1.132.1, DNS 194.168.4.100 IP / 194.168.8.100). The printer is connected wireless. We can print and I see that the printer is registered on the network.

  I tried:

  1 Manual IP and DNS: IP 10.0.1.249, DNS 8.8.8.8 / 8.8.4.4

  2. as stated above, but DNS changed to 194.168.4.100 / 194.168.8.100 - the same as AirPort Extreme

  3. automatic IP (10.0.1.7) but manual DNS (both variants above).

  After each change, I stop, wait and restart the printer.
