Unable to connect from a FactoryTalk client to a FactoryTalk Linx OPC UA Connector workstation

Possible cause and solution:
  • The
    FactoryTalk
     client or
    FactoryTalk Linx
    OPC
     UA Connector workstation does not have network connectivity.
    Verify network continuity between the
    FactoryTalk Administration Console
     or client application and the
    FactoryTalk Linx
    OPC
     UA Connector workstation.
    View the messages in
    FactoryTalk Linx
    OPC
     UA Connector >
    FactoryTalk
     Diagnostics Log
     to determine if a connection to the
    FactoryTalk Linx
    OPC
     UA Connector has been established.
  • The
    FactoryTalk Linx
    OPC
     UA Connector software is no longer running, has crashed, or its host computer is shut down or restarting.
    Verify the host PC is running. Use
    Windows
     Services to determine if the
    FactoryTalk Linx
    OPC
     UA Connector service is running.
  • The
    FactoryTalk Linx
    OPC
     UA Connector hostname, IP address, or fully qualified domain name is incorrect.
    Verify the hostname, IP address, or fully qualified domain name is entered correctly in
    FactoryTalk Linx
    OPC
     UA Connector > Computer hosting the
    FactoryTalk Linx
    OPC
     UA Connector
    .
  • The
    FactoryTalk Linx
    OPC
     UA Server hostname or fully qualified domain name is not resolved.
    Enter an IP address in
    Computer hosting the
    FactoryTalk Linx
    OPC
     UA Connector
     instead of a hostname or fully qualified domain name.
  • The network hosting the
    FactoryTalk
     client and
    FactoryTalk Linx
    OPC
     UA Connector does not support IPv4 connectivity.
    Ensure the
    FactoryTalk
     client and
    FactoryTalk Linx
    OPC
     Connector connect over an IPv4 only network.
  • Windows
     firewall or another software firewall is not configured to allow
    FactoryTalk Linx
    OPC
     UA Connector communications.
    For computers using
    Windows
     firewall, use the
    Rockwell Automation
    Windows
     Firewall Configuration Utility to permit the
    FactoryTalk Linx
    OPC
     UA Connector to listen on the specified IP address.
    For computers using other software firewalls, use the configuration utility included with the firewall to permit the
    FactoryTalk Linx
    OPC
     UA Connector to listen on the specified IP address and port number.
