SBC S-Web Technology
1. Should the PC be included in the automation pyramid?
A dedicated designed control PC (Windows PC) and control/management
software is no longer needed for recording and for regular operation
of the ICA technology of a property/site. Every 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
designed as part of the “automation levels”. This is realised in the form
of SCADA web pages which are loaded via the automation devices’ web
servers and displayed in the browser. A system and all connected devices/
sub-sections can be maintained, optimised and monitored in this way.
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 extremism:
Text displays in the field - 21” system images in the control centre
A single text display on the system does not provide the operators 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 brings usable, practical
system conditions “on site” and everywhere where 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. Every 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 than 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 needed with
SBC S-Web. Browser touch panels do not need any
dedicated software.
What difference does S-Web make to lean automation tender specifications?
