Configuring the OPC Alarm and Event Collector

Procedure

  1. Open the Historian Administrator.
  2. Select the Collectors screen.
  3. Select the OPC Alarm and Event collector instance you wish to configure.
  4. Configure the OPC Alarm and Event Collector's General options.
  5. Configure the OPC Alarm and Event Collector-specific options. Refer to Configuration of OPC Alarm and Event Collector-Specific Fields for more information.
    1. Click the Configuration tab.
    2. In the OPC Server PROGID field, enter the PROGID of your OPC Alarm and Event server.
    3. In the Link to Data Collector list box, select a data collector to link the Alarm and Events collector to. Alternately, you can enter the name of the collector to link to manually by typing it in the field.
      Important: Although the collector will function properly with no associated data collector, alarm and event 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.
    4. If you want to filter your events, enable the Filtering option and click on the Filters... button. Refer to Alarm filters for more information.
  6. Click Update to save your configuration.
    Note: To install additional OPC Alarm and Event collectors, you must re-run the Historian install.
