State-based alarming

State-based alarming is implemented for analog, rate, and status records. State-based alarming helps prevent nuisance alarms, which occur when the actions of devices affect the readings of other devices. High/low/creep/rate-of-change alarm checking is implemented for tables that hold floating record values, such as analog and rate records.

Status records can be configured to have normal and abnormal states. Analog records have LowLow/Low/High/HighHigh abnormal states and a normal state.
