OPC

UA Connector cannot connect or has lost connection to the

OPC

UA Server.

The

FactoryTalk Linx

OPC

UA Connector is actively monitoring for incoming connection requests from the OPC UA Server. This status only applies to the case of a reverse connection.

The

FactoryTalk Linx

OPC

UA Connector has detected the OPC UA Server configured for reverse connection and is retrieving its endpoint URL to establish communication.

The

FactoryTalk Linx

OPC

UA Connector fails to establish communication with the OPC UA Server through reverse connection and presents unsuccessful connection attempts for a duration of 10 seconds before switching the status to

Listening for connection request

. The failed connection count resets upon service restart or successful connection. Possible causes are as follows:

The network path to the OPC UA Server entered in the
Endpoint URL
box does not match the actual one.
The security policy configured in the OPC UA Connector does not match that configured in the OPC UA Server.
The OPC UA Server does not trust the security certificate of the OPC UA Connector.
The user ID or password that the OPC UA Connector is using to connect to the OPC UA Server does not match that configured in the OPC UA Server.

Adds an

OPC

UA Server to the

FactoryTalk Linx

OPC

UA Connector.

Removes the selected

OPC

UA Server from the

FactoryTalk Linx

OPC

UA Connector.

Sets the name for the

OPC

UA Server. The name must be unique. The server name displays in the

FactoryTalk

application tree and is included in the full tag path for all tags provided by the server.

Sets the description for the

OPC

UA Server as needed.

Sets the network path to the

OPC

UA Server. The path must be in the format of

opc.tcp://

hostname_or_ip:port

/

EndpointName

where

hostname_or_ip

,

port

, and

EndpointName

are replaced with the host name or IP address, port number, and endpoint name of an

OPC

UA Server and its local discovery service.

If no port is specified, the

FactoryTalk Linx

OPC

UA Connector will attempt to connect to port 4880.

The security system on the

OPC

UA Server must allow incoming connections to the selected port for the connection to succeed.

If the

OPC

UA server is on the same computer as the connector, enter

opc.tcp://

localhost:port

.

Typically, an

OPC

UA Server identifies its Endpoint URL within the server management interface. If the server or endpoint cannot be browsed, copy this URL from the server and enter it manually.

If the UA Connector is configured to operate in a redundant configuration, one additional selection is available:

All the settings and configuration of OPC UA Servers are the same as the primary and secondary URLs.

Enables or disables the Reverse Connection function by selecting or clearing this checkbox. After this property is initially configured, any change to it requires restarting the

FactoryTalk Linx

OPC

UA Connector service.

The @OPC_ReverseConnectEnabled diagnostic item is read-only.

Specifies the host name or the IP address of

FactoryTalk Linx

OPC

UA Connector.

When the OPC UA Connector is configured locally, select the host name or IP address from the list or enter the value in the box.

When the OPC UA Connector is configured remotely, the default is the host name. You can also choose to enter the IP address in the box.

Specifies the port of the OPC UA Client to be used for Reverse Connection. The port must not be used by another endpoint or application.

Tip

:

FactoryTalk Linx

OPC

UA Connector will verify the usage availability of the specified port. When the OPC UA Connector is configured locally, the port that passes the verification is available to use. When the OPC UA Connector is configured remotely, you must go to the local workstation to verify if the port is used by another application.

Generates the network path to the

FactoryTalk Linx

OPC

UA Connector in the format of

opc.tcp://

ClientAddress:ClientPort

based on the values specified in

Client Address

and

Client Port

. This value will be used by the OPC UA Server to initiate a reverse connection to the

FactoryTalk Linx

OPC

UA Connector.

This property is read-only. Select

Copy

next to this property to copy the value if needed.

Determines what type of encryption algorithm is used for protecting data passed between the

FactoryTalk Linx

OPC

UA Connector and the

OPC

UA Server.

Use either:

Determines how the connection between the

FactoryTalk Linx

OPC

UA Connector and the

OPC

UA Server is authenticated and whether the data is protected by encryption.

Use either:

Displays the path to the certificate provided by the

FactoryTalk Linx

OPC

UA Connector. If the

FactoryTalk Linx

OPC

UA Connector is hosted on a remote computer, the path represents the file location on the remote computer.

The default path is C:\ProgramData\Rockwell\OpcUaConnector\RnaUaClientDataProvider\PKI\.

Allows the FactoryTalk Linx OPC UA Connector to accept the certificate of OPC UA Server automatically. This checkbox is selected by default and cannot be cleared.

Uses an anonymous connection to the OPC UA Server

Specify the user name and password to use to log on to the OPC UA Server.

Determines the update rate for each UA server that the

FactoryTalk Linx

OPC

UA Connector uses to request a tag.

Determines how the

FactoryTalk Linx

OPC

UA Connector accesses data on the UA Server.

Selects this option to enable writing to arrays. This option works with the array access method to control writing data to the array.

When using the default array access method -

Operate on entire array at once (all elements)

- selecting this option results in writing the entire array if an element within the array changes. The array is read into memory, the elements that were modified are changed, and then the array is written back to the OPC UA server. There is a potential that the data on the OPC UA Server changed after it was read. These changes will be overwritten by the previously read data, which could lead to some data inconsistencies.

If the UA Server supports indexed arrays, selecting the

Access subset of array (indexed elements)

access method and then enabling this option results in writing only changed elements within an array. Before using this mode in a production system, test the results to confirm that the values are updating as expected.

Selects

Provide string tags for unsupported types

to convert the OPC UA Connector data types that are not supported in Live Data to strings.

Selects FactoryTalk Linx OPC UA Connector the source timestamp to be delivered with each tag value it receives and passes to a FactoryTalk Live Data client when the source timestamp changes.

Enables alarm and event support and activate the options on the properties dialog box by selecting the checkbox. By default, this setting is disabled.

Shows the alarm server status.

Used to enable group alarm severities. Grouping severities by priority level helps operators filter and sort alarms more quickly and distinguish among degrees of urgency.

Select the

Enable server-assigned priorities

checkbox to override default system-wide priority settings with

FactoryTalk Linx

OPC

UA server-specific priorities.

The following are the default server-assigned priorities and their associated default severity range:

By default, this setting is disabled. When the setting is disabled, you can view the alarms, but the alarms will not be recorded.

Used to select a database definition that receives data from the alarm server.

Tip: If you have not created a database definition, refer to

FactoryTalk Alarms and Events

Help

to create one.

Displays the name of the computer that contains the database.

Displays the name of the database to which the data is logged.

Displays the location of alarm and event data cache files. If the connection to a database is lost, alarm and event history is cached to files in this path. Once the connection to the database is restored, the information in the cache files is written to the database. Only change the default value if the location does not have enough free disk space.

The cache file location must be local to the computer hosting the alarm server so that events can be cached if the computer is temporarily disconnected from the network.

Enable this item to include events related to writing data to tag values in the diagnostic log.

Displays the most recent date and time that the

FactoryTalk Linx

OPC

UA Connector refreshed the namespace cache of the specified

OPC

UA Server.

Updates all tag information sent from the

OPC

UA Server.

Analyzes the namespace of the

OPC

UA server and saves a report of all namespace items that have unsupported data types.

The

FactoryTalk Linx

OPC

UA Connector saves the namespace on its host computer to the file

C:\ProgramData\Rockwell\OpcUaConnector\RnaUaClientDataProvider\AddressSpace\ConnectorName_ServerName_ServerEndpointURL.txt

. In the output filename, ConnectorName, ServerName, and ServerEndpointURL are replaced with the names and Endpoint URL of a
