ROCHESTER, NY, U.S.A.- AMETEK Power Instruments--a recognized leader in alarm management products--has introduced an advanced web-based alarm management system that captures critical alarms with one millisecond precision.
The SERNET Sequence of Events Recorder is a distributed, network-enabled alarm manager that captures critical alarms in the sequence they occur for quick determination of the root cause. The alarms are displayed on a web browser hosted by the SERNET for easy analysis and include real-time outputs via serial and Ethernet ports for connection to DCS, PLC and other plant monitoring HMI software systems.
AMETEK partnered with EATON Corporation in developing the SERNET using EATON's established communication platform for the web interface, NTP technology. It directly interfaces with EATON Powerware using Modbus and BACnet protocols.
Each SERNET unit can operate as a stand-alone system monitoring up to 48 digital inputs, or multiple SERNET units can be networked together to form a larger system with all events consolidated into a single chronological list as they occur. This distributed architecture saves on installation as SERNET units can be located throughout a plant in close proximity to the alarms eliminating long wire runs.
The advanced web browser displays alarms from multiple units providing a system view of all alarms within a plant or even throughout multiple sites all with the same time synchronization providing a real-time analysis of the plant conditions.
SERNET is configured via the web browser and includes various filtering and contact de-bounce tools to screen out nuisance alarms. Each SERNET unit is able to store 40,000 events for long-term data storage, and events can be downloaded in csv and ASCII formats. The web browser includes a graphical display and a list of events that can be sorted and filtered to make it easy to view alarms for determining the root cause.
SERNET provides e-mail notification of alarms and includes SNMP for network management and can be synchronized to real time through GPS clocks using IRIG-B and NTP time inputs. NTP helps reduce cost for distributed applications as a single clock can synchronize all units connected to the LAN.
