OPC Services on DeltaV 11.3

Hi everyone,

I have two questions regarding OPC services on DeltaV 11.3 :

a) Is there any way I could read on a module some of the diadnostic parameters of OPC Subsystem on an Application Station, i.e., OInteg, Clients, etc.?

b) Is there any way to manage the conecction clients to the OPC Subsystem, i.e., to force a disconnect on some particular Client connection?

Thanks in advanced for your attention and help.

Best Regards,

Marcos Moreno.

  • If you double click an item in Diagnostics it shows you the path to that item.  You can then access that path via OPC to get the value outside of Diagnostics.  The picture above shows a path in Diagnostics and then the same item browsed via OPCWatchit.

    I don't know of any way to programmatically manage connectivity with OPC clients.  That being said, it could certainly be possible and I just don't know how.
