Looking for assistance is reading and writing File ObjectTypes from our Beckhoff OPC Server. The following is a snippet from the server documentation that explains the functionality that has been exposed. I am able to access the files via a tool like UA Expert, but I am unclear how to achieve the same using Easy OPC.
I think this is as straightforward as calling the various methods on the folder and file types, but I am struggling with how to properly handle the byteString in the method calls.
Thanks for any guidance.
From OPC UA specification version 1.02, OPC UA contains a specialized ObjectType for file transfer, which is described in Appendix C of the specification. This special ObjectType called "FileType" describes the information model for the data transfer. Files can be modeled as simple variables in OPC UA with ByteStrings. FileType is a file with methods for accessing the file. The OPC UA specification provides further information about FileType and the structure and handling of the underlying methods and properties for accessing a file in the OPC UA namespace.
