Alarm Journal Profile and Alarms Configuration

This section assumes that an Alarm Journal Profile and alarms are already configured before proceeding with filtering alarms using a date range. To learn more about alarms, go to Configuring Alarms and Alarm Journal pages.

Alarm Journal Table

The Alarm Journal Table displays the complete history of all alarms within a specific time period. Ignition offers several types of date pickers under the Calendar tab of the Component Palette, but it's far easier and more common to use the Date Range component for filtering alarms over time. 

When the Alarm Journal Table component is initially placed on a window, the component shows the last 8 hours of alarm events stored in the Alarm Journal Profile. Typically, operators want to filter alarm events within a specific time period rather than scroll through a long list of alarm events. Selecting Start and End Dates is very easy using a Date Range component.

Alarm Journal - Filter on Date Range

Setting up Alarm Journal Table to Filter on Date Range

 The Start Date and End Date are built into the Date Range component so you can select the Start Date and End Date all in one place.

  1. In the Designer, drag the Date Range component from the Component Palette to your window and place it above your Alarm Journal Table. 




  2. Link the Alarm Journal Table component to the Date Range component beginning with the Start Date.

    1. Select the Alarm Journal Table component, click the Start Date binding  icon. The Property Binding window will open.
    2. Click the Property binding type.
    3. Select the Date Range component's Start Date.
    4. Click OK. 



       
  3.  Now, let's link the Alarm Journal Table to the Date Range component's End Date.  

    1. Select the Alarm Journal Table component, click the End Date binding  icon. The Property Binding window will open.
    2. Click the Property binding type.
    3. Select the End Date for the Date Range component. 
    4. Click OK.


       

  4. The Alarm Journal Table will refresh with all alarm events within that time period. Click on Preview Mode and drag the slider on a specified date range on the timeline. You can drag or stretch the selection box around the timeline. The selected date range is always a whole number of units, where the unit is determined by the current zoom level. You can also zoom in or out on specific time periods to see the alarm events that exist in the alarm history table.  



     

    Refreshing New Alarm Events

    Alarm Journal Table fetches data only when the window is first opened and when the Start or End Dates change. To see new alarm events come into the table, use the slider to change the dates.
