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 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.

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.

Advanced Alarm Management Options

MADB Master Alarm Database comes with following optional applications: Change Management, Dynamic Alarming, Rationalisation, Operator Assist.

Change Management

Dynamic data such as Alarm settings, instrument ranges etc can also be maintained, via a secure OPC DA client.

Can I know whether Alarm & Trip set points, ranges are same as per design or are they changed without approval? Can we have access & version control for all configurable parameters and know which are the ones approved? Dynamic Data are those which are changed frequently, say instrument ranges, alarm & trip points as well as tuning parameters. These are retrieved from control systems typically through OPC. Retrieval can be scheduled or on demand, through user friendly HMIqueries based on instrument, equipment, type. Multiple user roles. Secure OPC Client with read - write access on a per tag level basis is offered.

Discrepency List

you can query for Dynamic Data and view them, make changes, propose and approve. Periodically, say review unauthorized changes everyday via Discrepancy list. Authorized Enforcer users may write these changes to control system OPC server through secure OPC Client.

Change management Life cycle: Need to change - propose - approve - enforce via Secure OPC Client - change design data.

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 suppressed or 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.

Rationalisation-Rationalisation module provides the user with a simple and efficient tool along with secure OPC client.

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 define Operator assist - Alarm description, consequences, action to be taken and time to respond.

To reduce configured alarms to reduce uncontrollable alarm load

To correct alarm setting for nuisance / chattering alarms

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
