Bryan, A quick way I get these reports from DeltaV Explorer is through Applications ---> System Alarm Management option. You can then choose how you want to get the alarms (area, module, unit, node). This will create the table of all alarms configured. Choose the File ---> Print option and check the Print to XML file. This file can be imported to Excel. All of this takes only a few minutes.

Robert Sentz approach is a really good idea. The other way that you can export the information is using the Bulk Edit utility (File pull down menu > Export > User Defined. You can create a custom Format Specification File which just contains Module Name, Area, alarm enable parameters, and limits. Using this you can then select the items to export using a search result of all modules with a subtype containing something like 'AI' depending on how you have defined your module library. It isn't as elegant as Robert's solution but will work. You may need to repeat it for a number of different module types ie. PID.
In reply to scottjturner:
Mind that Roberts and Scotts methods will only give you the offline data. If alarms were en-/disabled online or alarm limits were changed online, they will not show up in the above mentioned exports. Same goes for PID tuning parameters. I recommend to also document those.
There are several ways to get this data as well. An easy way would be to do an upload of all controllers and look for modified alarm parameters. After the upload do an export explained before. Always be careful when uploading, because it will change the offline database. More advanced ways are to use VB scripting in iFix. (I run a similar script regularly to check for simulated process-values for example.)
Another thing to consider is that alarms are enabled and disabled dynamically by other control modules or phases etc. But this depends on the application and should be known by the software-engineers.
In reply to Robert Rijnders:
On line alarm assessment should be done through the event chronicle. The event chronicle contains information about every alarm that is both configured, assigned to a controller, and enabled. The chronicle is also updated of when an alarm limit or enable/disable state is changed both manually and programmatically. Process history view can be used for this purpose, but to get all data easily, it will probably be better to hit the SQL databases representing the chronicles (active and current) or the batch historian alarm tables (if configured to aggregate the chronicles) through query analyzer or SQL Server Management Studio. The specific query would need to use the latest record regarding each distinct module alarm to determine what the current on-line state is.
In reply to Youssef.El-Bahtimy:
I also use the bulk edit method to pull the alarms for all my modules. I then use Excel on the .txt file that is generated to create a list for the process engineer in each area to review. We also use the DeltaV alarm help so the spreadsheets are used to perform alarm rationalization. After rationalization you can update the information in the spreadsheets and reverse the process to update the Process Alarms in DeltaV.
