Alarm Management Software


SAMA Alarm Management & Analysis suite of software is part of Supra Advanced Manufacturing Analytics. It comes as SAMA AS Basic package; Alerts, Analysis, Metrics, Dynamic Alarm modules; Documentation (change management) & Rationalisation module; Root Cause Analysis module as well as Upset Predictor module.




Basic Package – Data Logger with AE client

Captures data from serial or Ethernet ports - typically data from DCS SCADA PLC SOE SNMP Traps, Postscript data, Files, ftp, OPC A&E, OPC DA, ODBC or direct connectivity with database such as Structware . Alarm server handles multiple date-time formats, event definition – alarms, operator actions, system diagnostic messages; track configuration changes and other messages; detect and store log reports, format & archive data. Detect alarm floods. Feature Rich Client, unique set of windows for each user, powerful real time search, sorting and filters.



Alerts module


Alerts can be sent based on Logical processing of events. Alerts can be made via Email, SMS, Dial out, audible alerts by speakers, PLC DO, Modbus, Interactive messaging can be achieved by Dialling in or SMS-in or E mail-in. Users can be alerted in groups as well as based on Shift Rota






Escalation based on time-in-alarm as well as frequency can be configured. If an alarm stays for more than say 5 minutes or f it alarms more than a certain number of times in a time window, it can be escalated.








Alarm Bands option is for multiple alarm bands on large video screens. Bands can be based on priority of event. Chattering alarms can be excluded. Latest alarm appears on the leftmost window and so on.








Dynamic Alarm Management

Alarm settings can be automatically changed , say based on throughput or Raw material mix or product Mix criteria; Or certain alarms can be disabled and enabled based on equipment running status; or in the case of batch to enable alarms only for those equipments which are in use.


Analysis Module


Analysis with dynamic charts as required by EEUMA 191 for Priority Distribution, Standing alarms, stale alarms, unacknowledged alarms, frequency, time-in-alarm & between alarms, alarm sequence display, chattering alarms and symptomatic alarms.






Alarm Metrics helps comply with ISA 18.02 standards. View reports for plant, area, unit, equipment over different time scales. Auto store, print and e mail reports.








Advanced Root Cause Analysis & Upset Predictor


Root Cause Analysis is exploratory. Root cause, which fulfilled the conditions, is highlighted, along with the path. Historical Root Causes can be selected and viewed as they are stored. If auto mode is chosen, auto relevance calculated (self- learnt automatically) is used to calculate adjusted probability. Real-time calculations include Relevance, Learn factor, probability and confidence level..





Overview gives glance of all defined trees and their current status. Upset Predictor uses similar technology. It helps operator and plant staff in identifying possible trips or upset conditions. Apart from monitoring through the Graphical user interface, SMS, email and call out alerts can be sent, giving sufficient lead time to avoid possible upsets or trips.





Dynamic DR Manager


Can we have access & version control for all documents, and know which are the ones approved?

Can I know whether Alarm & Trip set points are same as per design or are they changed without approval?

Can we do Alarm Rationalization? How do we handle Alarm set points for different process modes?

Is there an efficient context sensitive Operator help in place, apart from his access to different docs?

Can I make an adhoc query or query by document or asset?



Plant documents can be classified as Static Documents & Dynamic Data. Static Documents include Engineered Documents such as P&ID as well as Process Flow drawings, Data sheets & specifications, Instrument index, point data base, hook up or installation drawings, power supply & distribution, loop drawings etc; Device or system manuals; procedures and standards. Dynamic Data are those which are changed frequently, say instrument ranges, alarm & trip points as well as tuning parameters. Dynamic data is retrieved from control systems typically through OPC. This can be scheduled or on demand. User displays and reports include Discrepancy reports and audit trail.


Rationalisation tool provides the user with a simple but efficient tool.

To ensure consistency in alarm & trip point settings for similar equipment

To ensure correct priority is calculated for alarms

To reduce configured alarms to reduce uncontrollable alarm load

To correct mis-configured settings

To correct alarm setting for nuisance / chattering alarms

To remove Duplicate alarms

To aid in State based, multi process mode alarm systems

Audit & enforce
