  • LabVIEW 2017 OPC UA Toolkit


Kepware as OPC UA Server

Issue Details

I have created a Tag using OPC Quick Client following the following document: 
Connecting to the LabVIEW OPC UA Server VIs Using OPC Quick Client

I would like to write the Tag and I am using NI OPC UA Write VI.

When I run the VI a error occurs:
Error -35667 occured at NI OPC UA Client.lvlib:Write
Possible reason(s):
LabVIEW: (Hex 0xFFFA8EBB) The node path refers to a node that does not exist in the server address space.



To fix this error remove "ns=2;s=" from the node ID string input of the Write VI the header.
