To establish communication with a device, the associated Board, Port and I/O Device need to be correctly configured in Plant SCADA Studio's Topology activity.
If you use the Express Communications Wizard to connect to a device, these settings will be automatically configured for you. However, if you need to manually configure them, use the information outlined below.
Boards
