[safety instrumented function]
Operator response to alarms is important layers of protection (LOP). When implemented with good design, engineering and maintenance practices, an alarm can help reduce the safety integrity level (SIL) of a safety instrumented function (SIF).

Engineers and designers are highly skilled individuals. Forcing them to enter design changes using tables, forms and spreadsheets is unproductive and uneconomical, and it increases the likelihood of human error—this is the way that most instrumentation software systems currently work. For too long, software vendors have denied engineers and designers the simple practicality of a graphical visual engineering interface with “drag and drop” capability and inbuilt intelligence, ensuring changes are automatically replicated into all the associated data and databases.
