10.9 Stream 5 Exception Handling — This stream contains messages regarding binary and analog equipment
exceptions. Exceptions are classified into two categories: errors and alarms. Messages S5,F1 through S5,F8 of this
section provide basic alarm messages. The messages S5,F9 through S5,F18 provide extended capabilities for
Exception Handling. When using messages F1–F8, alarms may be divided into categories as follows:
1. personal safety — Condition may be dangerous to people.
2. equipment safety — Condition may harm equipment.
3. parameter control warning — Parameter variation outside of preset limits — may harm product.
4. parameter control error — Parameter variation outside of reasonable control limits — may indicate an
equipment malfunction.
5. irrecoverable error — Intervention required before normal use of equipment can resume.
6. equipment status warning — An unexpected condition has occurred, but operation can continue.
7. attention flags — A signal from a process program indicating that a particular step has been reached.
8. data integrity — A condition which may cause loss of data; usually related to Stream 6.
10.9.1 For messages F1 through F8, it will be the equipment’s responsibility to categorize the alarm. Some alarm
conditions may cause more than one type of alarm to be issued. For example, a parameter control error on over
temperature may also trip a protective device that makes the alarm irrecoverable without some intervention.
