0: The associated alert may clear when the priority is changed
to 0, but it will never occur.
1: The associated alert is not send as a notification. If the
priority is above 1, then the alert must be reported.
2: Reserved for alerts that do not require the attention of a
plant operator, e.g. diagnostic and system alerts. Block alarm,
error alarm and update event have a fixed priority of 2.
3...7: Increasing higher priorities - advisory alarms.
8...15: Increasing higher priorities - critical alarms.

R/W Limit used in square root processing. A value of zero percent
of scale is used in block processing if the transducer value
falls below this limit, in %of scale. This feature may be used to
eliminate noise near zero for a flow sensor.
