This document captures implementation details of the Virtual Remote Terminal Unit (Remote RTU) application on the Cisco IR809 router, which can be deployed as a secondary substation router in the Europe region or as a distribution automation gateway in the North America region. The Virtual RTU application's lifecycle is managed using the Cisco Fog Director. Eximprod, which provides our Supervisory Control and Data Acquisition (SCADA), is a Cisco Solution partner. The ES 200 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 ES 200.
