To set up CitectSCADA v7.20 communications with CTAPI applications in your system (including CitectSCADA Reports and Ampla), verify that these products have been upgraded to their latest versions before running any upgraded CitectSCADAv7.20 projects.
Similarly, if you are using any custom CTAPI applications, upgrade CitectSCADA on the computers where these applications are installed before upgrading any other CitectSCADA computers.
