Introduction

The following document explains custom alarm areas within iFIX, and how to properly use them with WIN-911 Scan and Alarm.

Discussion

WIN-911 listens for alarm updates via an alarm queue. Alarm updates coming from an alarm queue will include an Alarm Area and if you're using Custom Alarm Areas, WIN-911 will miss the updates. WIN-911 will only listen for Alarm updates using at least one of the default iFIX Alarm Areas which are the letters A - P. You can still use Custom Alarm Areas but you must also include at least one of the default Alarm Areas. This article will guide you through this process. 


Understanding iFIX Alarm Terminology

  • Alarm: A Block condition indicating that a process value has crossed a pre-defined limit and requires a response.
  • Operator Messages: System, database, or operator information that does not require a response.
  • Alarm Areas: A physical or functional division of a plant that acts as a routing table for alarms and messages.


Resolution


In order for WIN-911 to function properly, the alarm block must be assigned to at least one standard (non-custom) alarm area. iFIX allows blocks to be assigned multiple alarm areas, both standard and custom, including all areas.


In the screenshot below you can see this block is using a custom Alarm Area called Control, in order for WIN-911 to function properly, you must also include one the default Alarm Areas which again, are the letters A - P. You can see we've added the Alarm Area A. Make this change to all your Blocks and WIN-911 will now read the Alarm updates from the Alarm Queue.
