Exercise: Checking the Alarm Contents with Alarm Summary

• Alarm Configuration

• Checking the Operation

Alarm Configuration

1. Create an INT (INT16) tag named TANK LEVEL in the Tag Editor with an Initial Value of 50. Then, create four BOOL tags: PUMP 1, PUMP 2, DRAIN 1, and DRAIN 2.
   
   

   Open

   

    

2. Click Tools > Alarm Editor to bring up the Alarm Editor window. Configure four alarms for the tag TANK LEVEL with the conditions of “Greater Than 90.0”, “Greater Than 80.0”, “Less Than 20.0”, and “Less Than 10.0”. Enter the Alarm Names as “TANK LEVEL - HIGH HIGH”, “TANK LEVEL - HIGH”, “TANK LEVEL - LOW”, and “TANK LEVEL - LOW LOW”, respectively.

Open

3. Actions will be assigned to the ON Action and OFF Action fields of each alarm created in the previous step. Click on the dropdown menu for the ON Action field of the “TANK LEVEL - HIGH HIGH” Edit Alarm window and select Create New Commands. Click + Add New Command > Command Field Dropdown > Set Tag Value within the Command Editor window. Double-click the “…” in the Tag field to assign DRAIN 2, then press OK. Repeat this step for the OFF Action field, but uncheck the box in the Value field. Redo this entire step for alarms “TANK - HIGH”, “TANK - LOW”, and “TANK - LOW LOW”, with tags DRAIN 1, PUMP 1, and PUMP 2, respectively.

4. Within the “TANK LEVEL - HIGH HIGH” Edit Alarm window, navigate to the Descriptions tab and click New Description. Type “HIGH HIGH” in the title field and “TANK LEVEL > 90%” in the body field and press OK. Repeat this for the “TANK LEVEL - HIGH”, “TANK LEVEL - LOW”, and “TANK LEVEL - LOW LOW” alarms with “HIGH”, “LOW”, and “LOW LOW” in the title field, and “TANK LEVEL > 80%”, “TANK LEVEL < 20%”, and “TANK LEVEL < 10%” in the body field, respectively.
   
   

    

5. Click Insert > Alarm Summary, then click and drag on the page to add the Alarm Summary object.

6. Change the parameters within the Basic Properties (Alarm Summary) pane to configure the Alarm Summary object. Add Column 5 to the Active Tab by scrolling down to just below Column 4 and pressing + Add Column. Column 5 will automatically default to Description. Change the Width field to 200 by double-clicking 100 and typing 200.

Checking the Operation

1. Click Tools >Launch Simulator to launch the Canvas Simulator.
   
   

2. Double-click the 50 next to TANK LEVEL and place the number 5 there. Two alarms should occur since both alarms, “TANK LEVEL - LOW” and “TANK LEVEL - LOW LOW”, are satisfied, and you can check the contents of those alarms. Red text means the alarm is active. Additionally, tags PUMP 1 and PUMP 2 are set to 1 (True) because of the simultaneous ON Actions from the two alarms.
   
   

    

3. Setting the TANK LEVEL to 15 will resolve the “TANK LEVEL - LOW LOW” alarm and reset tag PUMP 2 to 0 (False). Green text means the active alarm was resolved.
   
   

    

4. Setting the TANK LEVEL to 85 will resolve the “TANK LEVEL - LOW” alarm but triggers the “TANK LEVEL - HIGH” alarm, resetting tag PUMP 1 to 0 (False) and setting tag DRAIN 1 to 1 (True).
   
   

    

5. Setting the TANK LEVEL to 95 will trigger the “TANK LEVEL - HIGH HIGH” alarm, setting the tag DRAIN 2 to 1 (True).
   
   

    

6. Setting the TANK LEVEL to 50 will resolve all alarms, resetting tags DRAIN 1 and DRAIN 2 to 0 (False).
   
   

    

7. Navigate to the Historical Alarm tab to view the archived alarm events.
