• Enable Alarming - Defines whether alarm processing is enabled or disabled.
Generates alarm messages indicating that a value has crossed pre-defined limits and
requires a response. Allows other blocks to detect an alarm from the block. An entire
chain can be affected when you disable alarms for a block.
• Enable Messaging - provides information about database events, operator inputs, or
system activities that do not imply potential problems. Records process activity, but
does not require an acknowledgment. Is sent to the same destinations as alarms for
a given block, but messages do not appear in the alarm summary link. Output blocks
generate messages whenever a value is written. If you check Enable Messaging,
you must check both the Enable Alarming and the Event Msg check boxes.
