Configuring the Connection to the PLC

The controller is connected through a gateway, which can be your development computer or a network computer connected to the controller. The Communication Settings dialog box is available for configuring this connection path. This dialog box opens automatically when you attempt to log in, but the communication settings have not been configured yet.
