Sierra Monitor Corporation Sentry Webserver - Manual (Page 2)

Sierra Monitor’s Sentry Gas Risk Management Sys-
tem has always been a leader in data handling for haz-
ardous gas monitoring systems for over 15 years. First
with digital 2-way communication bus from sensors to
controller, first with serial Modbus communication out-
put for plant-wide systems, first with the ability to in-
terface to other sensors and devices and now first to
offer a cost-effective web-based graphical system for
monitoring plant-wide hazardous gas conditions.
How it Works
All of the data available from the Sentry Modbus serial
communications link interfaces to the FieldServer via
an RS-232 link. The FieldServer contains the software
and interoperability features to convert that information
into a graphical display package that can be viewed by
Microsoft Internet Explorer browser. Standard introduc-
tory screens are provided free with the system to en-
able the user to quickly start operating. With the
WebServer option the user receives the FieldServer, con-
figuration software and the ActiveX tools necessary to
modify the provided display or create their own graphi-
cal display. These simple tools along with an already
familiar web browser means that the user does not need
to endure the cost of learning a new program and hiring
an integrator to develop the system. The system can
easily be designed to meet your specific graphical and
user interface needs using FrontPage from Microsoft.
Also, Sierra Monitor can provide graphical design and
development service if desired. The standard WebServer package includes an initial
“home” screen, one graphical “zone” screen, a tabu-
lar “zone” screen, and alarms screen plus an event
log screen. The user can then modify the Home screen
and Zone screens to meet their specific needs or add ad-
ditional screens using Microsoft FrontPage. Examples of
these screens are seen below. The Alarms page contains
all active alarms and notes whether or not they have been
acknowledged. The Event Log page notes all events (alarms
and change of states) that have occurred over a recent
period of time.
