Function
The EGX400 server is used as an Ethernet coupler for the PowerLogic System
devices and for any other communicating devices operating under the Modbus
RS 485 protocol.
It contains HTML pages (set up using WPG) that can be accessed using a standard
internet browser. The HTML pages are used to display the information provided by
the devices connected to the server.
SMS software and internet browser
The EGX400 server makes it possible to implement two types of user interface:
b SMS power-monitoring software providing access to all status and measurement
information. It also prepares summary reports
b a standard internet browser providing access to the main information organised in
predefined HTML pages.
These two approaches, SMS and internet browser, are complementary:
b SMS offers complete access to all information, but must be installed on each PC
b the HTML pages offer partial access to the main information via any PC connected
to the network.
