Don't you know all the node IDs of an OPC UA node in advance? The function browse iot node() browses the node at runtime. It writes the discovered node IDs to a list. This way, you can also process node structures that change at runtime.
Parameters
Parameter | Type | Default value | Description |
|---|---|---|---|
a | String (alias) | – | IoT server alias. Determines which configured IoT server the function communicates with. See IOT (Input agent). |
b | String (node ID) | – | Node ID of the node to search. Example: ns=3;i=1001. NOTE: Click the three dots at the field, then select IOT Node. This opens an IoT browser where you select a single value. |
c | String (list name) | – | Name of the list the function writes the discovered node IDs to. |
d | Boolean | false | Optional. If true, the function clears list c before it inserts new values. |
NOTE: Node IDs follow the OPC UA format
ns=<Namespace Index>;i=<Numeric ID>orns=<Namespace Index>;s=<String ID>.
