Testing and Health

Purpose

Verify that an endpoint and its NodeIDs actually deliver data, and monitor the ongoing health of a connection.

Actions

• Test — test the selected node.
• Test all — test every node on the connection at once.
• Reinitialize — restart the endpoint connection (applies configuration changes).
• Value inspector — view the latest raw and interpreted value for a node.

Health indicators

• Attention badge — the connection needs a look (for example a failing node).
• Missing current value badge — one or more nodes have no recent value.
• Current values — persisted last-known values per node, shown in the nodes table.

Steps

1. Open a connection from OPC UA Connections.
2. Select Test all and review the results summary.
3. For any failing node, open it, check the mapping, and Test again.
4. After configuration changes, Reinitialize the endpoint and confirm current values return.

What users see

A test results summary per node, status badges on the connection card and detail header, and current values in the nodes table.

Troubleshooting

• Test all reports failures -> Endpoint unreachable or nodes misconfigured -> Fix the endpoint/nodes, reinitialize, and re-test -> Review the Logs with the endpoint URL.
