A widespread issue in manufacturing plants is alarm overload. As formerly independent systems are integrated for more effective operation by fewer operators, each operator has to monitor an increasingly wider area and consequently deal with more alarms. Without rigorous alarm rationalization efforts, alarm flooding becomes a serious problem and increases the risk of safety and environmental incidents.
There are a number of documents such as EEMUA #191 and ISA 18.2 that help customers reduce alarms, but practical tools that can be implemented are still in short supply. Yokogawa proposes a smart approach to alarm management that helps customers achieve safe and agile plant operations based on the concept of combining practical bottom-up solutions with fundamental top-down improvements.
Yokogawa urges customers facing alarm flooding situations in their plants to introduce CAMS for HIS. It also benefits those who are looking for alarm management capabilities that go beyond the current generation of DCS alarm systems. Customers planning to consolidate their control rooms and design their alarm system to be in compliance with the ISA 18.2 standard will benefit from this product's practical and immediate solutions.

Alarm Reporting and Analytics (Exaquantum/ARA)
- Alarm Reporting and Analytics (Exaquantum/ARA)
- Prevent safety related incidents, environmental issues, shutdowns, equipment damage
-
Alarm Master Database (Exaquantum/AMD)
- Exaquantum/AMD
- Yokogawa Master Alarm Database solution
- Based on ANSI/ISA-18.2-2009 and EEMUA 191,
- Monitor, assess, audit alarm setpoints
- Alarm documentation/rationalization
-
Sequence of Events (Exaquantum/SER)
Exaquantum/SER is an event driven integrated reporting system that acquires alarm & event messages and point data from plant monitoring and control systems, and stores this information in a single database for ease of analysis.
-
Alarm Analysis (Exaplog)
The new Exaplog event analysis package facilitates the quantitative analysis of problems in the DCS event log. By alternating analysis with alarm setting adjustment and operation sequence tuning, you can continuously improve operational efficiency.
-
Dynamic Alarm Management (AAASuite)
Advanced Alarm Administrator allows alarm review, alarm optimizing, and enhancement of alarm response by simplifying the process of alarm reduction and minimizing alarm flooding.

Alarm management is not just a project that has a start and end date; it's a continuous cycle. Once the alarm system has been reviewed and improvements have been identified, we must check that controls are in place to ensure the alarm system remains functional. The key is to ensure that the system is continuously monitored and any changes are fully documented. There are seven key steps for alarm management. Rationalization is one of those critical steps.
Summarizing the standard's 10 stages into four general tasks can simplify implementation and speed up the schedule.
Modern historians do much more than just store process data. They also provide analysis, reports, and valuable operational and business information.

CAMS for HIS is based on recommendations for presentation of alarms to operators from EEMUA publication 191.
Exaquantum is a comprehensive Plant Information Management System (PIMS) incorporating a data historian for real time and historical data, alarms, and events along with aggregations, role-based views and KPIs, graphical HMI, trends, reports, and integration with different systems. It provides a cetralized repository for users throughout the plant and is the foundation for most of Yokogawa's production, safety, and alarm optimization solutions and operator effectiveness solutions. Exaquantum can acquire data from all facets of a process and transform that data into easily usable, high-value actionable information that can be made avaialable across the enterprise.
President & CEO of Yokogawa Electric Corporation of Japan, Shu Kaihori, discusses optimizing plant performance with Andy Chatha, President & CEO of ARC Advisory Group.
This Webinar will present a detailed look at a software demonstration of how to configure Yokogawa's Consolidated Alarm Management Software (CAMS) for HIS (Human Interface Station). How users can implement CAMS to meet some of the recommendations from EEMUA 191, ISA 18.2 and other published guidelines for alarm management will also be presented.
