Hi,

I’m new here and want to know how to get newest 

OpcRcw.Ae.dll

OpcRcw.Batch.dll

OpcRcw.Comn.dll 

I know the link is https://opcfoundation.org/deve…..omponents/

But inside the zip is a OpcComRcw.2.1.108.nupkg, I don’t know how to use it to get the above dll.

Thanks a lot.

I use 3.00.108 and unzip the following dll

OpcComRcw.dll

OpcNetApi.Xml.dll

OpcNetApi.dll

OpcNetApi.Com.dll

Did the above four dlls replace the original seven dlls?

The original dll are

OpcRcw.Ae.dll

OpcRcw.Batch.dll

OpcRcw.Da.dll

OpcRcw.Hda.dll

OpcRcw.Comn.dll

OpcRcw.Sec.dll

The old DLLs do not work with .NET 2.0 or later.

I’m also a newbie, and may in the same boat.  I need to port some of our .NET software from OPC DA Version 2 to Version 3.  I’ve downloaded both the opc-core-components-redistributables-3.00.108-20191220 and opc-net-rcw-2.01.108-20200806 mentioned above.

The dlls in 3.00.108 are NOT Assemblies, so I can’t just reference them in my .Net project, so I installed the NuGet packages from 2.01.108, but it’s not clear to me if those DLLs support OPC DA Version 3, because they all are labeled 2.01.108

Once I’ve replaced our existing references with the 4 DLLs in the NuGet packages, everything compiles and seems to run fine. But now my next task is to add Batch Read support.

I don’t see any Batch functionality in any of these NuGet DLLs.

So questions I have:

1) Do I have the correct NuGet packages for Version 3 ??

2) Do they cover all or most of the Version 3 API ??

3) Does Version 3 include Batch functionality ??

4) Am I heading in the correct direction ??

Thanks, LES

CoreComponents are C++ COM DLLs. The version 3.00.108 is unrelated to the specification version or the .NET API.

It is a prerequisite for the .NET API

.NET API. 2.01.108 NuGet package supports all specifications available for download here:
https://opcfoundation.org/deve…..ns-classic except for DA 1.0a.
