Description

The OPCUA client driver subscribes to single array elements which causes slow performance with an OPCUA server with a larger number of large arrays. (>150.000)

The peformance of the OPC UA client driver should be improved in regard to handling of large arrays.

Solution

The OPCUA client driver has been enhanced to allow a more efficient communication for large arrays in the OPCUA server.


The OPCUA client driver is now able to advise a complete array, rather than single items.

Also the request to translate the browsename into a NodeID has been limited to a maximum of 500 nodes per request.
