Lecture Notes: Alarm Handling in IQ Vision

Introduction

• Presenter: Leon Turner of Trend
• Topic: Alarm handling in IQ Vision
• Objective: Address how to change alarm formats and how to deliver alarms successfully from IQ controllers to IQ Vision.

Controller Setup

• Snapshot Overview:
  • Uses a couple of controllers with the same setup.
  • Trigger: Drives two internal digital inputs.
  • Inputs are fed through the group, root, and destination path in the controller.
  • Alarms are output as IP alarms directed to the laptop's IP address.

Alarm Delivery Process

• Alarm Classes:
  • Alarms are received and fed through different alarm classes.
  • Delivered to a "console recipient"—day-to-day alarm view.

Viewing Alarms

• IQ Alarm Demo Overview:
  • Launched from the controller called "IQ Alarm Demo".
  • Includes virtual points and various information from the controller.
  • Alarm Trigger Button: Fires alarms in the controller.
  • Alarms initially go to the default alarm console and default alarm class.

Alarm Consoles

• Default Alarm Console:

  • Displays alarms from digital input modules.

• Alternative Alarm Console:

  • Shows both acknowledged and cleared alarms.
  • Different view option available that shows acknowledged and cleared states.

Alarm Format Customization

• Common Question: How to modify alarm format?

• Alarm Extension Level:

  • Changes to alarm format are made at the alarm extension level.

• Modifying Alarm Text:

  • Adjust settings to show desired information (e.g., parent display name, controller hosting name).
  • Can include hyperlinks and alarm instructions.

Batch Changes for Alarms

• Program Editor:

  • Suitable for changes to multiple points.
  • Allows applying changes to thousands of points.
  • Introduced later in IQ Vision versions.

• Alarm Manager:

  • Found under Trend Systems folder.
  • Trend Source Mapper: Adjust default alarm format for point alarms.

Filtering Alarms

• Specific Alarm Consoles:

  • Example with alarms "Pump Fail" and "Boiler Tripped".
  • Use filters to route alarms to different consoles.

• Alarm Preprocessor:

  • Found in the property sheet for trend systems.
  • Filters alarms based on labels or other info.
  • Allows enabling/disabling filters for specific alarms.

Advanced Alarm Management

• Alarm Filters:

  • Created by duplicating existing filters or adding new ones.
  • Customize based on desired conditions (e.g., label contains "Boiler").

• Use Cases:

  • Black building tests, managing multiple alarms simultaneously.

Conclusion

• The lecture provided a comprehensive overview of customizing and managing alarms in IQ Vision.
• Recommended to refer to IQ Vision documentation for further details.
