Does there exist an OPC-UA equivalent of OPC-DA "readasync" and "writeasync"

Hello All,

I have been using OPC-DA with the with great succes in Matlab. I used the "async" type for reading and writing values, as this was nessesary to speed up the communication compared to standard the OPC-DA read and write. I am forced to use the OPC-UA type now, but can not find the equivalent "async" function for reading and writing. Standard "readValue()" and "writeValue()" is too slow, as with OPC-DA.

Do any of you know a way to read and write to the OPC-UA server using the async method? Or is there a workaround, so that my proram does not need to stop while reading and writing..?

Kind Regards Lars Petersen
