This section explains each of the properties in the configuration blade.
This associates the Agent to a specific Collection (default to that of the current Data Stream).
Polling Interval (seconds)
A timespan to specify how often should the Agent check for new data/changes or update its cache.
Once the Server Url is provided, the Agent will attempt to connect to the OPC UA Server and retrieve its available Endpoints. Selecting an Endpoint will populate the Security dropdown with the available User Security Policies for the Endpoint.
Tick to select saved Server Url, User Name, and Password variables; or enter the text manually.
The Url of the OPC UA Server to connect to.
The Endpoint of the OPC UA Server to connect to. Each Endpoint follows a different Protocol, Security Mode, Security Policy, and Message Encoding.
Auto Accept Server Certificate
Tick to auto accept the certificate during server authentication.
The authentication options are:
The User Name used to authenticate with the server (applies to UserName Security only).
The Password used to authenticate with the server (applies to UserName Security only).
When the Connection details are completed, the Agent attempts to authenticate with the OPC UA Server. If successful, the Address Space of the Server is made available to the Agent, allowing the navigation of Branches.
The method used to navigate to the Node where the Tag values are retrieved:
The dot-separated Branch path to the Node where the Tag values are retrieved (applies to Using Dot Notation Branch Navigation only). A path that is invalid or does not exist will not display any available Tags.
Do not use dots (.) in the Branch names to ensure the Address Space is traversed correctly.
Level 1 (up to Level 10)
Select the Branch path to the Node where the Tag values are retrieved - limited to 10 Levels (applies to Using Drill Down Branch Navigation only).
Once the Branch is provided, the Agent retrieves the available Tags for that Branch. Tag Value and current Timestamp is updated on the selected Tag when published.
The available Tag values for the branch specified.
Add Selected Tags
Tick to add the selected Tags from Available Tags selection to the Tags Grid.
Tags Grid (Tag, Tag Value)
The grid defines the values to be published:
