To add a new continuous tag to the Tag Watch List:

  1. Click Add . The Adding window opens.

    Adding window

  2. Enter the tag's details:

    • Tag - Enter a name for the tag. This name needs to be unique in the j5 Event Manager application. The name can remain unchanged even if the underlying data source or process tag name changes.

    • Variable Type - Select Continuous from the list.

    • Datasource - Select the tag’s data source from the list.

    • Datasource Tag - Select the tag from the list.

    • UOM - Enter the appropriate unit of measurement for the tag’s data.

    • Site, Section, Area, Unit - Select the operational area information for where the tag is positioned.

    • Monitoring Strategy - Choose how the data is retrieved.

      • Poll: This option retrieves a single value at each polling interval.

      • Query for Updates: This option retrieves all values since the last retrieval occurred.

      • Subscribe for Updated: This option receives values pushed to it by the data source and does not poll. This option may result in a high network usage, as the number of push events is determined by the data source. The number of entries with this option should be carefully considered and tested.

    • Target Polling Frequency - If you select Poll or Query for Updates, choose how frequently the data is retrieved.

  3. Enter a tag Description.

  4. Set the tag limits (Target High/Low, Standard High/Low, and Critical High/Low). Refer to the Continuous tag limits section for more information.

  5. Set the Deadband on the tag limits. Refer to the Deadband section for more information.

  6. If aggregate event information is required in another application, select the relevant application from the Target Form list.

  7. If a Target Form is selected, enter the Aggregate Period (minutes). This determines how long the events will be grouped together (one entry) in the target form. If there is another event after the aggregate period has expired, a new entry is created in the target form and the aggregate period is started again.

  8. Click Save . An Enable Monitoring dialog box appears.

    Enable Monitoring dialog box

If you click No, the tag monitoring can be enabled later by clicking Edit and then selecting Enabled from the Monitoring Enabled? list.
