Comments |
This technique is ideal for use in alarms, for it "cleans itself up." If an alarm’s trigger condition is set to WeekBeforeExpire(NG#), and its Trigger When State is set to true, the alarm will trigger during the last five business days of the lead-month contract. Once expiration has passed, and first out month rolls to the lead month, the function evaluates false. |
