HI
I want to send image (jpg, png, bmp) on OPC UA server from my delphi app.
How I will create Image node on simulation server and how in delphi implement that ability?

Exists any sample code or documentation?

Thanks a lot!

Unfortunately, there is no way to define image data in the Simulation Server at the moment. You could do that with the Delphi SDK quite simply, though. The image variables just need to declare the DataType properly. The data is provided a TUaByteString, which is defined as

TUaByteString = array of Byte;

So, you will just need to create a TUaVariant with that kind of data.

And the same principle works in the client and server – I was not even sure which one you are creating with Delphi.
