OPC UA Connection configuration

Pascal

Dear users,

I need to communicate between a DeltaV Project (V14.3) and a Citect project (2018 R2 Update 17) . In my Citect project I have to access some tags of the DeltaV project, a temperature measurement (Real) and a value of type UINT.

The result on display is as follows:

I can read the temperature but it is impossible to read the UINT value ?!

The result with TagDebug after several 'Read' attempts

To make sure that the OPC UA server is ok I installed another client on the Citect station to test the communication:

Communication is working properly and tags are read normally. 

Can anyone help me solve this problem!
Thanks in advance

  • Hi Pascal,

    That's strange. Configuration looks to be all-right.
    Have you installed the newest driver already? v3.04.06.000 is currently the latest version available from the Support site.

    Do you get any errors in the kernel and/or syslog file of the I/O server? Or any errors on the OPC server side that may hint at an issue?

    Also, do you see bad quality or any errors if you try to read the tag using TagDebugForm() instead of TagDebug() ?

    If nothing is showing out of place, then perhaps Support may be able to assist you.

    Regards,
    Patrick
