1 CHAPTER OVERVIEW
This product supports Substation Automation System (SAS), and Supervisory Control and Data Acquisition (SCADA)
communication. The suppor
t embraces the evolution of communications technologies that have taken place since
microprocessor technologies were introduced into protection, control, and monitoring devices which are now
ubiquitously known as Intelligent Electronic Devices for the substation (IEDs).
As standard, all products support rugged serial communications for SCADA and SAS applications. By option, any
product can support Ethernet communications for more advanced SCADA and SAS applications.
