Network Variables currently provide support for OPC DA. However, the industry has been moving from OPC DA to OPC UA (Unified Architecture). The reasons for this are many, but mainly based on security and ease of use. Surveys over the last couple of years show that there are now more devices and applications being produced with OPC UA support than DA support. I have enquired whether NI are planning to support UA technology, but it seems that this is not in the pipe line.
There are solutions available (open62541, for example) that may provide a solution. Does anyone have any experience with using this solution with CVI?
