Honeywell
Alarm Handling - General
6.1 General
You can set various alarm configurations using the MSC-L menu. Also,
the active alarms and alarm logs can be viewed through the MSC-L
menu.
6.2 Basic Concepts
An alarm is an indication that an undesired situation has occurred. In
MSC-L, the following collection of information is associated with an
alarm.
Name

Scope

State

Action

Date

Time

6.2.1 Alarm Name
The alarm name is used for describing the situation in which the alarm
has occurred.
6.2.2 Alarm Scope
Conceptually, an MSC-L device has loading bays. A bay has multiple
loading arms and loading arms have zero or more streams associated
with them. They are referred to as scope type.
There are five scope types in the MSC-L as follows:
Device

Bay (or transaction)

Loading arm (or batch)

Product stream

Additive stream

On the alarm log screen, the emphasized first character of the alarm
chapter is used for indicating the chapter to which the alarm belongs to.
Consider the example of an Tank empty alarm on product stream 3. The
scope type is a Product stream. But this information is not enough to
uniquely identify the source of the alarm. The index of the product
stream, 3 in this case is missing.
