How do I pull the last 3 months of historical data from all of the alarms in a tag provider?

Hi all, I got a request to obtain all of the historical data of our alarms from the last 3 months and if possible download to a CSV/Excel file. Is this possible? And if so, how?

You'll need to script something to use system.alarm.queryJournal to fetch the alarm data. The return format is a list of pyAlarmEvents, you'll likely need to loop through this to pick out the information you want to export.

From there, convert it to an excel or csv format, and write it to a file using system.file.writeFile

If you assemble your data you plan to export into a dataset, you can pass it to system.dataset.exportExcel or system.dataset.exportCSV to have Ignition handle the conversion and file writing for you.
