Networks for Wide Area Automated Systems
PCD controllers support the connection to the WAN (Wide Area Network) via all established telecommunication technologies. The IP-
based protocols (automation server) are used to connect directly to the Internet either wired via Ethernet interfaces and DSL broadband
routers or wirelessly with GPRS/UMTS routers. Non-IP based connections with analog, digital (ISDN) or GSM modems are also supported.
The PCD3.WAC (Wide Area Controller) allows a direct connection via the integrated analog, ISDN or GPRS/GSM modems.
Protocols and services
The WEB/IT protocols are used to support access to the automation server functions (web/FTP server, email, SNMP, etc.).
The S-Bus protocol enables communication with the PG5 programming device, the SBC OPC server or Visi.Plus. S-Bus is also used
to exchange data between PCD controllers via the WAN.
Other IP-based protocols such as Modbus TCP and BACnet® are also supported.

Wide Area Automation with Saia PCD®
Spanning geographical distances with a larger number of substations often places significant demands on a system. The integrated
automation server can be used to combine geographically distributed systems easily using the Internet and Intranet. This allows
the systems to be monitored and controlled remotely. It is possible to access the controllers directly during commissioning or servicing.
