XWEB is a Controlling and Monitoring system based on "WEB server" technology. In this document we can
refer to XWEB as 'server'. It is capable to communicate data to one external Client with the same kind of
procedure used by the Internet Web Sites. Client need only a standard Browser such as Microsoft
Explorer.
The Web Pages with all the information are contained into the server itself; Linux operative system ensures
maximum efficiency and security.
The server reads, logs and checks the data coming from the Dixell instruments connected to a RS485 line.
The communication protocol is the Modbus-Rtu. The XWEB is capable of recognising also most of the
Modbus-Rtu compatible instruments not manufactured by Dixell.
ATTENTION: Always check the proper RS485 connections (see 2.1.1 rs485)
ATTENTION: Dixell S.r.l. reserves itself the right to analyse the Modbus-RTU compatibility of other
manufacturer's devices before ensuring their integration into XWEB system.
