Yokogawa has developed a new concept
for the rationalization of alarm management and is now introducing this in a new software
package called the Consolidated Alarm Management Software for Human Interface Station
(CAMS for HIS) embedded in its DCS. This Yokogawa solution reduces alarm flooding.
It is well known that operators experience problems with alarm flooding in process control
and monitoring. This is the first ever package that is dedicated for use by operators who are looking for
appropriate solutions to the problem of alarm flooding and by engineers who lack the time to implement
engineering measures for the reduction of alarms.
CAMS on HIS
has a function for the acquisition of all alarms and events from the DCS,
including subsystems. The alarms and events are processed by the standard sorting/filtering, eclipsing, shelving, and
load shedding functions of the package. Value-added information on items such as the root cause of alarm
occurrence, role-based actions, and previous action procedures help operators respond to alarms even
more quickly. The addition of identifiers (e.g. purpose of monitoring, alarm
priorities, time allowed to respond, user names) in the course of day-to-day
operations ensures operators receive only essential alarms at the right time.
When the number of alarms is reduced on the monitoring display, the most important alarms will not be
overlooked and operators can devote more time to taking care of them.
This effort during routine operations to eliminate less critical alarms ensures that management can focus on
those alarms that are most essential over the long term. CAMS on HIS also helps with the implementation of a top-down alarm
rationalization approach to deal with alarms over the long term.
CAMS for HIS delivers only optimal alarms to the right person at the right time. It improves
alarm monitoring efficiency and provides guidelines for the practical reduction
of alarms.
