Description
High alarm condition detection. Set to enable detection of the High alarm condition. Clear to disable
detection of the High alarm condition.
Default is set.
Low alarm condition detection. Set to enable detection of the Low alarm condition. Clear to disable
detection of the Low alarm condition.
Default is set.
Low Low alarm condition detection. Set to enable detection of the Low Low alarm condition. Clear to
disable detection of the Low Low alarm condition.
Default is set.
Specifies whether alarm acknowledgement is required. When set, acknowledgement is required. When
cleared, acknowledgement is not required and HHAcked, HAcked, LAcked, LLAcked, ROCPosAcked, and
ROCNegAcked are always set.
Default is set.
Set by the user program to acknowledge all conditions of this alarm. Requires a cleared-to-set transition
while the alarm conditions are unacknowledged.
Default is cleared.
