Time Stamp at Source At the heart of an effective alarm & event management system is the ability to handle avalanche conditions without losing events or losing track of time. The advanced MAXIFLEX 32SOE Module and Terminal Board technology Sequence-of-Events architecture to meet these needs. At the core of this architecture is the advanced MAXIFLEX 32SOE module. This module microseconds and queues any changes of state The 32SOE Event Flow Management detected in a front-end queue within the module that can hold up to 9362 events. Ahead of the front-end queue in every 32SOE module is a...

Compliant Alarm Annunciation Alarm Annunciation Each MAXILARM alarm node is pre-programmed with a full function alarm annunciator. Up to 240 points of alarm annunciation can be configured with your choice of any of 27 pre-programmed alarm sequences, compliant with ISA-18.1 ISA SP18.02 and EEMUA 191. If none of these suit your needs, then you can configure your own. PER MAXILARM ALARM NODE Up to 240 alarm points includes “First-Out” Alarm annunciator sequences. These providing operators with the earliest possible indication of the root cause of failures, even in the face of a large number of...

Alarm Windows improve reaction times Alarm Fascias Traditional window alarm annunciator fascias provide the fastest means of alarm notification to operators in the face of avalanche conditions. MAXILARM provides the option of adding alarm fascias to any MAXILARM node. Omni-X Alarm Displays OMNIFLEX manufactures a wide range of alarm displays to suit the application. The most popular range of displays for MAXILARM systems is the Omni-X series. Sizes from 8 to 144 Windows Bright Back-Lit Display. Any Configuration The Omni-X Remote Displays provide from 8 to 144 points of annunciator display...

Networking for the harsh environment Choice of Network MAXILARM, as a distributed alarm and event system, relies upon a data network to interconnect the remote nodes with a supervisory computer such as the Omni4000 Alarm and Event Station. MAXILARM supports two network choices: Ethernet Ethernet has become the leading industrial network on the modern plant, and MAXILARM supports Ethernet communications. Conet There are many situations where the laying of dedicated network cabling to integrate the alarm and event system is impossible or cost prohibitive. To suit these situations, Omniflex...

Seeing the complete picture System Integration No alarm and event system stands alone. All alarms are part of some larger control system, and relating the alarms to the rest of the plant is vital to quick diagnostics, and hence reduced down-time and increased safety. Omniflex understands this and has added to MAXILARM the ability to integrate other data into the Alarm and Event System, so that this data can be logged and viewed together with the alarms and events. Analogue Inputs The MAXIFLEX hardware platform includes a comprehensive set of analogue input modules that can be included in...

OPC Standard Interface Choice of Supervisory MAXILARM is designed to work with a supervisory computer system for alarm and event logging, operator control and system administration. Omni4000 Omniflex recommends the Omni4000 Alarm and Event Station which is purpose designed with the tightest integration with the MAXILARM system. The Omni4000 interfaces to the MAXILARM AES through an OPC server, allowing multiple operator stations to co-exist on the system. OPC Server A key component to the supervisory interface is the Omniflex Conet/OPC server. The Conet/OPC server has the ability to accept...
