Configure the OPC Alarms and Events Collector

About this task

The following table provides the OPC Classic Alarms and Events collector-specific configuration fields.

Procedure

  1. Access Historian Administrator.
  2. Access the OPC Classic Alarms and Events collector, and then select Configuration.
  3. Provide values as specified in the following table.
    Field Description
    OPC Server PROGID The PROGID of the OPC Alarms and Events server.
    Link to Data Collector The data collector to link to the alarms and events. This allows you to join alarms and events data with tag data when querying the Historian database for data. This is usually located on the same server as the OPC Alarms and Events server.
    Filtering Enables or disables filtering of the alarms and events data. For information, refer to Filter Alarms and Events Data.
    Show Last Alarms Displays the last 10 collected alarms and events data points.
    Close Alarms Opens the Close Alarms window.
    Important: Although the collector will function properly with no associated data collector, alarms and events data will not be associated with tag data from the data collector if it is not specified in this field. As a result, queries through the Excel Add-in or the OLE DB provider will not be able to join tag and alarm data.
