S-Net for communicating between Saia PCD® devices
2.5.1
The basic features of S-Net
S-Net incorporates the S-Bus and S-I/O system protocols for
communicating between SBC devices. Both protocols are optimised
for SBC devices and compared to other standard protocols
(e. g. Modbus) they offer greater functionality and are simpler
and more efficient to use.
S-Bus
supports all services and functions regarding the exchange
of data, programming, commissioning and service of Saia PCD®
controllers. The S-Bus protocol does not depend on the physical
aspects and can be used on Ethernet, USB, Profibus-FDL and serial
interfaces (RS-232, RS-422, RS-485).
The
S-IO
protocol supports the operation of SBC remote I/O stations
with Ethernet (PCD3.T66x) and Profibus (PCD3.T760)

Services and functions using S-Bus
Programming and commissioning
S-Bus is the programming device system protocol. It supports all programming,
commissioning and diagnostic functions.
The programming device is accessed via Ethernet,
USB or serial interfaces.
Exchanging data between PCD controllers via
Ethernet, Profibus or serial interfaces
Connecting to SCADA systems via Ethernet, USB,
Profibus or serial interfaces
Access to the PCD web server is also possible via
USB and Serial interfaces
Visualising with web browsers
S-Bus supports HTTP protocol transmission. This also allows websites to be transmitted
together with “SBC-Web.Connect” via USB and serial interfaces and displayed
on a Windows PC with the standard web browser or a micro-browser web panel.
Visualising with OPC servers and SCADA systems
S-Bus together with an OPC Server or the SBC.Net-Suite supports access (reading
ad writing) to all PCD data with a Windows SCADA system.
Exchanging data between PCD controllers
S-Bus supports the transmission of all PCD media (register, flags, timer/counter,
database and text) and is optimized for the exchange of data between PCD controllers
whereby Ethernet and Profibus allow multi-master operation.
Serial interfaces (RS-232, RS-422, RS-485) enable “single”-Master-Slave mode or S-Bus-
Master-multpile-Slave mode.
