This video demonstrates how to change a RealFlo license in the Schneider-Eletric SCADAPack.
Please note that you will have to provide a Controll ID to the Schnider-Electric guys as the RealFlo license is attached to the SCADAPack Controller ID. YOu can get the Controller ID using either Telepace, RealFlo software or a sticker affixed on the SCADAPack itself.
