The scanner communicates with devices via strobe, poll, change of state, or cyclic I/O messages. It uses these messages to solicit data from or deliver data to each device. Data received from the devices, input data, is organized by the scanner and made available to the controller. Data sent from your controller, output data, is organized in the scanner and sent on to your devices.
