Variables can be sent to Distributed Control System (DCS) to trigger an alarm. Suitable trigger levels vary from application to application. Guidelines for appropriate values can be determined by logging Signal Quality Metrics over time and viewing minimum/maximum values. The Signal Quality alarm trigger value should be at least 1, but a better guideline is 2-3.
