How to install a Sx2WEB system 

5

 

 

1.1 The master unit: Sx2WEB24 (SH2WEB24 or SB2WEB24) 

 
The system is based on a central CPU, the Sx2WEB24, a Linux based embedded PC that manages all 
the smart functions. It is programmed by means of powerful software, the Sx tool. The Sx2WEB24 has 
the Ethernet communication capability to be remotely controlled and monitored by smart-devices/PCs; it 
is  also  a  data  logger  that  can  record  any value/event  coming  from  the  many  buses  it  can  connect  to 
(Wireless and Dupline®  buses, two  RS485  ports, Ethernet).  This master unit is also provided  with an 
SD-card and USB port to upload/download data and system configurations. 
The Sx2WEB24 is the brain of the system. It collects all the information from the buses it is connected 
to. All the field devices such as light switches, input/output modules, sensors and so on  are connected 
to the Sx2WEB24 via the Dupline® bus. The Dupline® bus is not generated directly by the Sx2WEB24 
but a bus generator is needed, the SH2MCG24. 
 
 
 
 
Here below a diagram of the system is shown.
