mean that two separate alarms are configured on a single variable with either two
high or two low trip points.
The high, low, and rate of change alarms are extensions of output limiting. For
example, the OUTPUT HIGH LIMIT specifies the maximum output value. This
value is used as a limit in modes where limiting is allowed by the LIMITED
OUTPUT MODES field. In a similar manner, the high and low setpoint alarms can
be limited by the LIMITED SETPT MODES field. Ratio and bias are limited by the
LIMITED RATIO MODES and LIMITED BIAS MODES fields.
