OPC UA Adapter

OPC UA client with browse, scan, and NodeId addressing.

OPC_UA connects to an opc.tcp:// endpoint and reads NodeIds. Tag browse and scan are supported in the console.

Connection config

FieldDescription
endpointUrlRequired — e.g. opc.tcp://192.168.1.10:4840
username / passwordOptional
securityPolicyOptional — None, Basic256Sha256, etc. (default None)
browseRootOptional NodeId or path for browse starting point

Tag addresses (NodeId)

ns=3;s=Counter
ns=2;i=1001
i=2258

Browse and scan

  1. Save device with valid endpointUrl
  2. Open device → TagsBrowse or Scan
  3. Import discovered nodes; adjust tag codes and units
  4. Export CSV / Import CSV for bulk edits

ScanTagExplorer (large servers)

For servers with thousands of nodes, Scan opens a folder tree explorer (similar to an OPC Quick Client):

  • Expand OPC folders in a tree; search by node name or browse path
  • Select nodes with checkboxes; the pick list paginates so you are not loading the entire address space at once
  • Import selected nodes — then refine codes, units, and active flags on the device Tags tab

Use Browse for a shallow preview; use Scan when you need structured multi-select from a deep hierarchy.
