PCo & OPC UA: Where to get the core components 1.0 redistributable?
PCo 2.0 requires the "OPC core components 1.0 redistributable (build 224 or later)" (Installation Guide, p. 9) to be able to create a source system of type OpcUaClient. Otherwise the creation fails, because the Opc.Ua.Core assembly could not be found.
But where to get these OPC UA core components? www.opcfoundation.org just offers the core components for the old OPC DA (2.0 & 3.0), which works by the way.
There is a "OPC UA SDK 1.00 Redistributables Setup (x86)" at OPC foundation, which includes the required DLL, but is only available for corporate members of the foundation.
Where can I download the core components?
Info from SAP:
The most official way to get the right dll's [Opc.Ua.Core.dll and Opc.Ua.Client.dll]would be to go to the www.opcfoundation.org -> Downloads -> SDK page, register and get the latest version of the "OPC UA Local Discovery Server 1.00". This package is available for non OPC members.
When installing this SDK the two DLL's that PCo needs in order to run OPC UA would be located in a folder like " C:\Program Files (x86)\Common Files\OPC Foundation\UA\v1.0\250
" or "C:\Program Files\Common Files\OPC Foundation\UA\v1.0\250"
When running now (again) the PCo 2.3 installer, our installer detects these dll's and simply copies them into the folder where PCo is installed, usually
C:\Program Files (x86)\SAP\Plant Connectivity\System.
Starting the PCo then again, you can create and run an Agent based on an OPC UA Server as source.
From PCo 2.3 SP 1 on the OPC UA version 1.00.250.8 is required (see release notes).
