CHAPTER OVERVIEW

The MiCOM products support substation automation system and SCADA communications based on two
communications technologies; serial and Ethernet. Serial communications has been around for a long time,
and there are many substations still wired up this way. Ethernet is a more modern medium and all modern
substation communications is based on this technology. Alstom Grid's MiCOM products support both of
these communication technologies.
