Some analog points have different types of alarm limit to those mentioned in this guide. For example, the range supported by some analog points is Underrange to Overrange, rather than Zero Scale to Full Scale. The Procedure for Configuring an Analog Point’s Limits is typically similar, regardless of the type of limit. The driver guides explain any limits and configuration differences that are driver-specific.
Analog points can also be configured to:
- Have two sets of alarm limits (see Multiple Alarm Limits)
- Use a separate set of limits at the server (see Master Station Alarm Limits)
- Have Multiple Point State Alarms (in which case an additional Alarm column is displayed in the Alarm Limits section of the Point Form).
