Driver.CredentialsHandling (PROP) ¶ PROPERTY CredentialsHandling : IDatasources.IDriverCredentialsHandling If this kind of driver requires credentials for logging in to a specific kind of device, then this property can return an object handling the assignment of credentials.

Driver.DataByteOrder (PROP) ¶ PROPERTY DataByteOrder : IDatasources.ByteOrder Returns the byteorder of value data managed by this instance. Note It is not expected that this value changes at runtime. Important Please remark that this value does not give information about the byte order used by the connected device but merely returns the information about the byteorder of data managed by |IDataItemValueAssigner| .
