Hello!I would like to install the NI OPC server via the Data Logging and Supervisory Control (DSC) module. All of the DSC module components has been installed successfully but the OPC server component fails and throws me an error before it rolls back.Error 1935. Error has been occured during 'OpcRcw.Hda, Version='1.20.1.21', Culture='neutral', PublicKeyToken='9A40E993CBFACE53',ProcessorArchitecture='MSIL' ' installation.Continue?Yes or NoI'm using Labview 2013 32bit with Pro license on Win7 64bit system. I have previously checked the posts related to this issue but none of those solved my problem.Not working for me:- disable firewall/anti-virus etc.- run as administrator- use Microsoft registry key fix- uninstall/reinstall DSC module- I have.NET v4.5.
FrameworkCould you help me to solve this installation issue?Regards,Bence. Hello Bence,this error is a general Windows Installer issue, which according to numerous articles available on the web can be caused by corrupted.NET components, missing permissions, registry size limits amongst others. To pinpoint to root cause specific to your case please create a MAX report (please see the following ) and attach it to your reply, that contains the installation logs.Another thing that you have not tried yet is to repair or reinstall your.NET Framework installation.
Please check if either one helps.Regards.
Additional Information Communicate to OPC UA Server with LabVIEW DSC 2013 - 2016 or LabVIEW 2017 OPC UA Toolkit using the OPC UA APIFrom LabVIEW 2013 to 2016, the LabVIEW DSC module contains an API for programmatically communicating with and exchanging data between OPC UA servers and clients. Starting with LabVIEW 2017, OPC UA Toolkit was released separately from the LabVIEW DSC Module and became a stand-alone LabVIEW toolkit. See for more information on this process.Communicate to OPC Server with LabVIEW DSC 8.0 and later using Shared VariablesStarting with LabVIEW 8.0, the LabVIEW DSC module extends the functionality of the Shared Variable Engine (SVE) to allow LabVIEW to serve as an OPC DA client. OPC Server Functionality is provided by the separate NI OPC Servers software. See for more information on this process.Communicate to OPC Server with LabVIEW DSC 7.1 and previous using the Tag EngineThe LabVIEW DSC Engine (Tag Engine) takes care of OPC for you. Because LabVIEW Datalogging and Supervisory Control is an OPC Client, it is much more efficient at OPC operations. If you are going to have more than 30 I/O points, you will sacrifice efficiency using data sockets. At 30 I/O points, you should consider using LabVIEW DSC and the Tag Engine.Because LabVIEW DSC is an OPC server, an OPC client can launch the Tag Engine.
When an OPC client launches the Tag Engine, the Tag Engine loads the current.scf file. The Tag Engine can then load any servers that the tags in that.scf file require. However, an OPC client cannot specify which.scf file the Tag Engine should use. The Tag Engine will only use the current.scf file, so you must make sure the correct.scf file is set as the default if you want this type of access.When you access data from the Tag Engine acting as an OPC server, the client software, such as Lookout or some other OPC client software, sees the Tag Engine as an OPC server named National Instruments.OPCLabVIEW, while the tag names you set in the.scf file appear as the OPC item names.Communicate to OPC Servers through DataSocketThe DataSocket protocol has an OPC layer, which allows you to read and write to an OPC server using DataSocket. Starting with LabVIEW 5.1, any version of LabVIEW can connect to an OPC Server as a DataSocket Client.LabVIEW ships with an example that demonstrates the above process. To access the example in LabVIEW, go to Help » Find Examples to open the LabVIEW Example Finder.
Once the Example Finder opens, click Browse and then navigate to Networking » DataSocket » OLE for Process Control (OPC) and you will see the example ( Monitor OPC Items with DataSocket.vi).Note: DataSockets cannot communicate with OPC Server 3.x.
