This document captures implementation details of the Virtual Remote Terminal Unit (Virtual RTU) application on the Cisco IR8x9 Integrated Services Router and Cisco IR1101 Integrated Services Router Rugged, which can be deployed as a secondary substation or as a distribution automation gateway. The Virtual RTU application's life cycle is managed using the Cisco Internet of Things (IoT) Field Network Director (FND). Eximprod, which provides our Supervisory Control and Data Acquisition (SCADA), is a Cisco Solution partner. The ES200 is Eximprod's Virtual RTU application. When we use Virtual RTU terminology in this document, we are referring to the only software we have validated—the ES200.
