I have an alarm database where the alarms would show when the value of a signal is changed from a 0 to a 1. However, I also need to show alarms whose values change from a 1 to a 0. How would I go about to accomplish this?
Using which Control system ?
In the Signal Configuration, under the Common Tab, you are able to invert the value. This allowed me to accomplish to task.
Return to Normal (RTN) condition cannot be an alarm.
Use Alarm expression to accomplish this.
