1. What is CAMS for HIS (Human Interface Station)?

Stands for Consolidated Alarm Management System Consolidation of real-time alarms

Acquired from DCS(CS 3000), SIS(ProSafe-RS), AMS(PRM), NCS/PLC(STARDOM )

Consolidation of historical alarms and events A&E and SOE

Consolidation of alarm-related applications Alarm design Real-time monitor Historical viewer Change management Statistical analysis and report

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

Acquisition: Acquiring all available A&E online real-time Normalization: Removing dialect or mismatch of

information Re-classification: Re-classifying alarms or events

Alarm prioritization: Prioritizing alarms based on purpose &consequence

Attribute addition: Adding identifiers and value-added information

Grouping: Unifying redundant alarms Suppression: Suppressing nuisance alarms

Filtering: Extracting necessary alarms Sorting: Sorting alarms based on urgency or

importance Eclipsing: Integrating repeated alarm in a single line Shelving: Shelving unnecessary alarms temporarily Load shedding: Activating predefined filter automatically

in case of alarm flooding

3. Feature functions of CAMS for HIS

8

Acquisition

Acquisition: Acquiring various types of alarms and events from sub-systems Types of alarms

DCS (Process alarms, System alarms, etc..) SIS (Safety related alarms) Asset management system (Field device alarms) Network Control System (Process alarms)

Types of interfaces Proprietary control bus interface OPC A&E Serial port logger (under consideration) FTP (under consideration), etc.

9

Normalization & Re-classification

Normalization: Removing dialect or mismatch of information Data arrangement Standardizing terminology (e.g. High, HI, H+) Level of alarm priority Level of plant hierarchy, etc.

Re-classification: Re-classifying alarms or events Examples

Correct events that were incorrectly classified as alarms

Vice versa

10

Attribute Addition Attribute addition: Adding identifiers and value-added information

Identifiers Purpose: safety, environmental, financial Consequence: very large, large, medium, small Time to respond: urgent, quick, routine Plant hierarchy: plant, area, unit, line Alarm priority: critical, high, medium, low, logging Type of user: operator, maintenance, production staff

Value-added information Reason of alarm occurrence Role-based action to be taken Past action

11

EclipsingEclipsing: Integrating repeated alarm in a single line

Chattering alarms can be visually hidden. Alarm shown after Eclipsing will be the one with the highest

priority and latest time stamp.

12

Grouping & Suppression

Grouping: Unifying redundant alarms Same alarms acquired from different sub-

systems

Suppression: Suppressing nuisance alarms Suppressing obvious alarms statically (e.g.

alarms generated by stopping plant)

13

Filtering & Sorting

Filtering: Extracting necessary alarms By timestamp, plant hierarchy, alarm priority,

user name, purpose, consequence, etc.

Sorting: Sorting alarms based on urgency or importance By timestamp, alarm priority, time to respond,

etc.

14

Examples of Filters SIS: Alarms from SIS Field devices: Alarms from PRM Stardom: Alarms from Stardom System: DCS system alarms Process: DCS process alarms

Plant A: Alarms in plant hierarchy Alarm Priority: High/Medium/Low Time to Respond: Urgent/Quick/Routine Purpose: Safety/Environmental/Financial

Operating Shifts: Alarms in each shift Start Up: Important/Unimportant

Combination filter also can be created.

15

Shelving

Shelving: Moving unnecessary alarms to the shelf temporarilyExamples of shelving functions

One-shot: Moving unimportant alarm into a shelf one by one.

Continuous: Moving unimportant alarms into a shelf once, then repeated alarms are automatically moved for certain periods or by certain clock time.

Automatic: Assigning one of existing filters as a condition of shelving, then relevant alarms are automatically moved for certain periods or by certain clock time.

16

Load SheddingLoad shedding: Activating predefined filter

automatically in case of alarm flooding If 100 alarms has happened within 60 sec, then

automatically select high priority filter. (This is the default setting and can be configured per customer preference.)
