x_y_Priority
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 Determines if the values passed by the TB to the AI block may
be used directly (Direct) or if the value is in different units and
must be converted linearly (Indirect) or with square root (Ind
Sqr Root), using the input range defined by the transducer and
the associated output range.
