SBC S-Net networking concept
SBC S-Net is the name of the new flexible networking concept for innovative and
economical automation solutions with SaiaPCD.
Based on the open standards Ethernet-TCP/IP (Ether S-net) and Profibus
(Profi S-net): Utilization of existing network infrastructure
no double ca-
bling required
Supports multivendor and multi-protocol operation:
Reduce costs for project planning, programming, commissioning and mainte-
nance thanks to end-to-end use of Ethernet TCP / IP and Profibus with S-Net
for the Private Control Network (PCN) for SaiaPCD
Consistent use of web technologies via Ethernet TCP / IP and Profibus for com
-
missioning, operation, monitoring and diagnostics
Integrated programming and commissioning via Ethernet TCP / IP and Profibus
Integrated network connections in the base unit Profibus interface integrated in the
operating system of the new PCD3 controllers and PCD3 RIO (included in the
base unit at no extra cost)
Profi-S-Net with optimized protocols and services for the efficient operation of
PCD3 RIO and PCD3 controllers on Profibus
Multi-protocol operation:
The new PCD3 controllers and PCD3 RIOs support Profibus-DP and S-Net on
the same connector
Continuity and investment protection:
Alle Saia PCD systems can be integrated in the concept with the existing Profi
-
bus and Ethernet TCP / IP connections.
