Interface between an OPC UA server and the Alarm Control Center

    The OPC UA agent enables the connection of the Alarm Control Center (ACC) to an OPC UA server. It reads out data such as message text, alarm bit, client or alarm group from the connected OPC UA server. These can then be used by the Alarm Control Center for alarm processes.

    Platform-independent with OPC UA

    OPC UA (Unified Architecture) is the successor to the old OPC Classic standard and has a platform-independent, service-oriented architecture. Communication no longer takes place via COM/DCOM, but purely binary via TCP/IP.

    OPC UA also integrates the functionality of the previous OPC Classic standard into an expandable framework.

    OPC UA agent - connection as a client

    The OPC UA agent processes incoming and outgoing messages that are received from an OPC UA server.

    The structure preceding the OPC UA server is irrelevant. Whether the connected OPC UA server is a single PLC, a complex control system or even a chain of control systems to whose last link the OPC UA agent is connected makes no difference to the agent.

    The OPC UA agent connects as a client to the OPC UA server mentioned and subscribes there to the data it requires.

    Increased reliability with the Monitoring option

    The Monitoring optionprovides increased fail-safety. The option monitors all functions of the Alarm Control Center and additionally provides the following functionalities for the OPC UA agent:

    • Agent function check: It is checked whether the agent is successfully connected to the OPC UA server and can perform write operations.
    • OPC UA server connection check: It is checked whether the connection to the OPC UA server is available.
    • Message load: It is checked whether a defined number of incoming messages at the OPC UA agent is exceeded within a defined period of time.
    • OPC UA device availability: It is checked which devices are additionally connected to the OPC UA server.
