Read out a OPC UA server via the OPC UA client

I would like to read out a OPC UA server via the OPC UA client possibilities of C8y.

I have several tags that I need to capture at 50 ms which is not problem. However to avoid having a lot of data, I have a trigger available to me that tells me when the sampling should happen. So if a certain tag is 1, I want to sample some parameters, when it is zero, I do not sample.


According to the documentation it should be no problem:

https://reference.opcfoundation.org/Core/Part4/v104/docs/5.12.1.6


Please see support ticket SI-510167 for more context

    Hi Nathan,

    you are right – this functionality is supported by OPC UA in general. Unfortunately, this is not the case for the SDK our gateway is based on, which is why we would have to implement this functionality ourselves. We will consider it for future implementation but won’t be able to plan for it yet as we have too many other items we have to work on first.

    Best regards,
    Aaron
