Utilities are migrating their substations from serial to Ethernet communications. Given the amount of serial communications in energy infrastructure today, the migration will take place over a number of years. The 8-port Async/Sync serial module in the Cisco CGR 2010 helps transport legacy SCADA (supervisory control and data acquisition) traffic across a TCP/IP network.
The serial interfaces provide a converged communications solution while energy infrastructure is migrated from serial-based Remote Terminal Units (RTUs) to Ethernet enabled RTUs and Intelligent Electronic Devices (IEDs). This supports network convergence andeliminates the need for costly separate leased lines for this traffic.
