  1. First, we will create a new “Event (Alarm) Log”. This object will be found in the “Data/History” tab:

  2. Select the “New” button to create a new log:

  3. Within the “General” tab, you can fine-tune your alarm settings. This includes selecting a “Category” (A) and, if necessary, a “Priority Level” (B). Additionally, you’ll need to choose between two options for the “Type”. Select “Bit” if you want the alarm to trigger when a specific bit changes state. Opt for “Word” if you prefer to set up a condition (E) within the “Enable if the value is:” boxes. This condition will activate the alarm if a value meeting the specified criteria is attained. Finally, choose a memory address (D) that does not overlap with any other objects in your project:

  4. Next, navigate to the “Message” tab, and within the “Content” box, write the message you want your alarm to display:

  5. After setting up your “Event (Alarm) Log”, we will create an object to display the alarms you have configured. Within the “Data/History” tab you can select “Alarm Bar”, “Alarm Display” or “Event Display” to display alarms. For this demo, we will be using the “Alarm Bar”:

  6. Within the “Alarm Bar” object, you can modify the “Scroll Speed”, what categories are displayed, and the transparency of the bar. You can also modify how to sort the messages in the alarm bar within the “Sort” tab:

  7. Now, your alarm bar should be configured to display alerts from your “Event (Alarm) log”!
