Data source configuration settings

Name

Required

Data source name

Data source description

Optional

Description of the data source configuration.

Mapping Type

Required

Select one of the following:

Generic
TagsOnly
PCS7
ISA95

Discovery or Server Endpoint URL

Required

The endpoint URL of the OPC UA or Discovery server.

For example, the URL format is:

opc.tcp://OPCServerHost:Port/OpcUa/SimulationServer

To discover the endpoints, select Discover Available Endpoints and then pick the desired endpoint.

Note: Not all OPC UA Servers support Discovery Available Endpoints. This is not a requirement in the OPC UA standard.

Select Discover Available Endpoints if the endpoint given is a discovery server or if the OPC UA Server can display the available endpoints.

If you know the full connection string and security policy/mode is known, enter the string and select Save. Otherwise, the discovery may fail even if the endpoint is valid for the connector to connect

User Name

Optional

User name for accessing the OPC UA server. Default is empty string.

Password

Optional

Password for accessing the OPC UA server. Default is empty string.

Root NodeIds

Optional

List of comma separated NodeIds of those objects from where the connector will browse the OPC UA server address space. This option allows selecting only subsets of the OPC UA address space by explicitly listing one or more NodeIds which will be included into the initial browse. For example:

ns=5;s=85/0:Simulation

In effect, only this node and all its underlying descendants will be considered.

Default is empty list, which means the whole address space will be browsed.

Note: An exception to it is the case when the PCS 7 mode is selected, then the following string is pre-populated in the Root NodeId's input:
ns=1;s=f|[ProjectName]::SIMATIC S7 Protocol Suite
The [ProjectName] shall be replaced with an existing project name listed under the OpenPCS7 object in the PCS 7 hierarchy. At least one such Root NodeId must be included.
