opcUaClient-OpcUaDevice

This device-level component in an OPU UA network represents a client connection to a specific OPC UA server and contains the configuration properties necessary for the driver to communicate with the server. The OpcUaDevice has a points device extension (OpcUaClientPointDeviceExt) that contains all subscribed proxy points.

Figure 9. OpcUaDevice properties

The default view for an OpcUaDevice is the Opc Ua Client Manager.

In addition to the standard properties (Status, Enabled, Fault Cause, Health, Alarm Scorce Info, and Poll Scheduler), these properties configure an OPC UA device.

Property	Value	Description
Server Endpoint Url	URL	Defines the connection address (URL) for the Opc Ua Server, for example: opc.tcp://IE67DTDVYXX.honeywell.com:52520/OPCUA/N4OpcUaServer
Security Mode	drop-down list (defaults to `Sign Ecript Basic256 Sha256`)	Specifies what security should be applied to message exchanges during a session. `Sign Ecript Basic256 Sha256` signs and encrypts all messages. The signature or signing of the message detects if it has been manipulated by any third party. `Sign Ecript Basic256` `Sign Basic256 Sha256` `Sign Basic256` `Sign Ecript Basic128Rsa15` `Sign Basic128 Rsa15` `None`
Certificate	drop-down list (defaults to `tridium`)	Selects the client’s TLS certificate. The default self-signed certificate should be approved and used only until a signed certificate is available.
User Authentication Mode	drop-down list (defaults to `User Name and Password`)	Configures the type of user authentication. For a successful connection, these settings must match the OPC UA server’s `User Authentication Methods` settings. `Anonymous` `User Name and Password`
User Name	text string	Configures the user’s name. User authentication by `User Name and Password` requires this property be set. The username and password must be defined in the station’s UserService.
Password	text string	Configures the user’s password. User authentication by `User Name and Password` requires this property be set. The username and password must be defined in the station’s UserService.
Server State	read-only	Reports the current condition of the server.
Server Current Time	read-only	Reports the current time as maintained in the server.
Server Start Time	read-only	Reports when the server came online.
Time Interval	hours minutes seconds (defaults to 30 seconds)
Status Check Timeout	hours minutes seconds (defaults to 10 seconds)
Server Info	additional properties	Displays read-only data read from the OPC UA server configured for the device. These data are documented in a separate topic.
Alarm Ext	additional properties	Opens the Opc Ua Client Alarm Manager. A separate topic documents this component’s properties.
Points	additional properties	Opens the Opc ua Client Point Manager that contains device point data. A separate topic documents this folder’s related discovery preferences.
Histories	additional properties	Opens the Opc Ua Client History Import Manager. The Histories AX Property Sheet configures the driver’s Retry Trigger. This typical set of properties are documented in the Niagara Drivers Guide.

Actions

Ping sends a message to a network object (device, database, etc). The message provokes a response, which indicates the current state of the object.
Learn discovers device objects.
Reset Comm enables and disables the device (closes and reopens server connection).
