Summary0002979: ServerCapabilitiesType::MaxByteStringLength missing
Description

With FileType we have a way to transfer files of any size.

In FileType::Read, a client can limit the data size returned with the length parameter and the server can further limit the returned data length. Therefore the limits of both sides are known.

In FileType::Write, a client must decide about the size of the data to write. But there is currently no way for a client to get the ByteString size limits of the server.

Additional Information

Proposed change:
Add Property MaxByteStringLength

The MaxByteStringLength Property indicates the maximum length of ByteStrings supported by Variables or FileType Objects of the Server. The Server might further restrict the ByteString length for individual Variables or FileType Objects without notice to the client. Servers may use the Property MaxByteStringLength on individual DataVariables or FileType Objects to specify the length on individual nodes. The individual Property may have larger or smaller values than MaxByteStringLength.
