Chapter 4-WEB Browser Alarm and Events Display Option
This option provides the ability to see alarms and events with timestamps via the WEB Browser
display. The WEB Browser display option provides an Active Alarm page and an Event Log page.
Active Alarms
This web page will display any inputs that are currently in the Alarm State. The alarms are displayed
in chronological order and can be color coded to differentiate alarms that have been acknowledged or
returned to normal. New alarms are automatically updated on this page as they occur. In systems
equipped with the CR (Combined Rack) option, all the alarms from multiple Logic Card Racks will be
presented on one common Active Alarm Display page for easy determination of root cause. Alarms
include their data and time stamp, station ID, device ID, input number and pre-configured alarm
legend.
The web display also includes an Acknowledge Pushbutton so operators can respond to alarms
remotely. There is a selection for latching alarms in case you want them to remain on this display
when they clear until they are acknowledged. Otherwise, they will clear from this display when the
alarm returns to normal.
Event Log
This web page is used to view all alarms, past and present , up to 1000 events max. It displays the
date and timestamp when the inputs went into alarm and returned to normal. It also logs any
diagnostic events and monitors the external time synchronization status. The alarms are presented in
chronological order, but can be sorted by any field: date and time, event type, station ID, device ID,
input number. It will store a maximum of 40,000 events.
In addition, the event log can be filtered to display events in a specific time frame, type of events or
specific alarm inputs so you can create a custom report detailing the information you need. You can
then download the events into a csv file and send them to a printer on your network.
