Consolidated Alarm Management Software (CAMS) for Human Interface Station (HIS) ー CAMS for HIS

One is a practical approach that sorts out alarms and displays only those alarms that require operator actions. The other is a fundamental approach that allows defining only the necessary alarms in accordance with EEMUA Publication No. 191 which is regarded as the de facto industry guideline for alarm management.

CAMS for HIS helps customers thwart the problem of alarm flooding, a potential cause of troubles in the plan, with the aim of ensuring safe operation. It also provides operators with an environment that frees them of tedious repetitive alarm tasks and allows them to focus on true process concerns.

CAMS for HIS is an alarm management software designed based on a totally new alarm concept. That new concept is to acquire real-time alarms and events from various systems - not only from CENTUM but also Plant Resource Manager (PRM), Safety Instrumented System ProSafe-RS and Network-based Control System STARDOM; then to sort and deliver only the necessary alarms to the right person at the right time. Important information such as the root cause of alarm occurrence or role-based guidance can also be added to the displayed message.

The number and variety of alarms and events handled in the plant are increasing substantially as plant operations become more complex. This software takes two engineering approaches to help rationalize alarms with the aim of preventing alarm flooding.

What is CAMS for HIS?* Have you ever missed a critical alarm or made an erroneous judgment because of alarm flooding?* How do you rationalize and implement your alarms? * Do you want to enhance the alarm monitoring functions of your DCS?

•EEMUA Publication 191A guideline for design, management and procurement of optimum alarm systems published in 1999, which has been prepared by EEMUA (Engineering Equipment and Materials Users Association) Sub-Committee formed by representatives of EEMUA member companies and the HSE (Health and Safety Executive).

Various identifiers for sorting alarms can be defined. In addition, various types of value-added information can be defined for alarms to help users take role-based action for alarms quickly and accurately.

• Examples of identifiers for providing only necessary alarms Purpose of monitoring (e.g. safety, environment, economic efficiency), operation mode to be monitored 　 　　(e.g. at plant startup, during steady-state operation)

• Examples of identifiers for providing an alarm only to the person who needs it (e.g. user name)• Examples of identifiers for providing an alarm at the right time Maximum allowable time to respond, estimated amount of loss, alarm priority• Examples of value-added information Root cause of alarm occurrence, role-based action to be taken, previous action procedures

“To deliver the necessary alarms to the right person at the right time”

• Prioritizing Alarms A function to help set alarm priority and to allow only necessary alarms in accordance with the criteria 　　　recommended by EEMUA Publication No. 191. When you input the purpose of monitoring and consequence, 　CAMS for HIS determines the alarm priority quantitatively in accordance with user-defined rules.

• Alarm Suppression Alarms coming from an out of service units can be suppressed based on predefined alarm groups.

Alarm Definitions Following Industry Guidelines

CAMS for HIS provides an operational environment that allows users to define only necessary alarms in accordance with established industry standards like EEMUA Publication No. 191.

Alarm Flooding Can be Reduced Just by Installing the Software

● Sorting/Filtering Alarm messages can be filtered and sorted using identifiers included in the alarm messages as the keys. 　 Basic filters such as a process alarm filter or a plant-hierarchy filter can be used without configuration. Filters unique to individual users can be defined, and temporary filters can also be created flexibly.

● Eclipsing Alarm messages that are activated repeatedly by the same tag can be integrated and displayed on a single line. Reducing the number of alarm messages displayed on the window will allow operators to reach the critical alarms more 　　 　quickly and easily.

● Shelving Unnecessary or nuisance alarms can be moved to a temporary area called a shelf in order to “hide” alarms due to special 　　circumstances. Individual unnecessary alarms can be manually moved to the shelf.

Chattering alarms or alarms that match user-defined conditions can be automatically moved to the shelf. This enhances operations by allowing an operator to eliminate the distraction from alarms that are of no current operational relevance.

● Load Shedding If many alarms are displayed by an unexpected event in a short period of time, predefined filters can be automatically activated 　to reduce the monitoring load.

● Seamless Operation with DCS　Screen linkage, beep sounds, LEDs, alarm verification actions, and the like are completely integrated into the CENTUM VP and CENTUM CS 3000　to ensure the seamless operation.

CAMS for HIS provides many functions that are ready to use immediately after installation. Alarm flooding will significantly be reduced immediately on the spot with built-in capabilities.
