SBC S-Web Technology
1. Should the PC be included in the automation pyramid?
Specifically designed control PC (Windows PC) and control/management
software are no longer required for recording and for the regular operation
of the ICA technology of a property/site. Each device and system already has
its own integrated control/management function.
2. Local versus central – bottom-up versus top-down
In the individual systems, the control/management function is already de-
signed as part of the “automation levels”. This is implemented in the form of
SCADA web pages which are loaded via the automation device web servers
and displayed in the browser. This allows the maintenance, optimisation and
monitoring of a system and all connected devices/equipment. The historical
operating data and alarms are stored locally in the automation devices.
Analogy: As with SBC S-Web, with BACnet the “SCADA” function is integrated
as an object in the BACnet automation device!
3. The end of extremes:
Text displays in the field - 21” system images in the control centre
A single text display on the system does not meet the operator’s needs. A
large screen in the remote control centre is also of little help: its complexity
is also slightly daunting for non-specialists. S-Web provides usable, practical
system conditions “on site” and anywhere a network connection is available.
Depending on the complexity of the application, a 5…10“ touch panel with
web browser is designed for the system control cabinet. A text display is not
suitable for the web technology. The local browser panel works only as a
client and loads its applications from the control devices (server) as required.
Each browser device connected to the LAN/WLAN (PC/mobile device) also
has access to the plant operating/monitoring.
S-Web requires fewer fixed on-site panels compared to classic technology.
This reduces costs and saves space.
Example of a real design specification for lean
automation: Each system already has a SCADA
function embedded.
This separate item is no longer required with
SBC S-Web. Browser touch panels require no
dedicated software.
