If selected, all the modules - including front-ends, sorting modules and conveyors - are polled at regular intervals to query their status. If not selected, only the status events sent by the sorter control unit are received.

Polling allows more reliable and complete status of the device to be displayed, for example a sorting module does not send any information if it is not available - only by polling the module is it possible to determine, that the module is not available. However, polling also causes traffic in the control channel of the sorter and should only be used if such accuracy is needed in the Visual Status Monitor system.
