Use a Third-party OPC Client to Access Alarm Server Data

You can use a third-party OPC client application, such as Matrikon, to access your Plant SCADA system and view alarm server data. To do this, you need to initially register a Plant SCADA alarm server as a runtime OPC AE Server. This requires administrative privileges.

Note: The OPC AE Server does not support DCOM for remote communications. It is recommended that you run any connecting OPC client applications on the computer that is registered as the OPC AE Server.

To connect a third-party client application to an OPC AE Server:

1. Run the Setup Wizard.

2. On the General Options Setup page, dialog select Register.

   The will register the alarm server as an OPC AE server and make it accessible to the third-party OPC applications.

3. Run the third party application.

4. From the list of available servers select the following:

   Serck.ScxV6OPCAE.<AlarmServerName>.<IP address>

   Where:

   <Server Name> is the name of the registered alarm server.

   <IP Address> is the address defined in the Network Address settings.

5. Connect to the OPC AE Server and create an event subscription within your third party application.

   The events retrieved from the OPC AE Server will be listed. The information returned to the OPC client may differ slightly to what is presented on Plant SCADA's alarm pages.

   Note: Do not attempt to connect an OPC DA application to a Plant SCADA alarm server. This is not supported and will not be enabled in any future releases. This is only intended for use with OPC AE clients.
