# Operation Mode »Mirror Image«

A combination of two or more Raindancer Beacons can optionally be used to reflect another device to be remotely monitored and controlled. Using this method, all signals coming from or going a Beacon will be available to a »Mirror« Beacon, via a »virtual cable extension«. Periphery connected to the »Mirror« (e.g. a PLC) can retrieve this information, process it and control the remotely  
controlled device via commands sent from this »Mirror« to its actual counterpart.

<p class="callout info">The number of devices configured as »Mirror« are practically unlimited.</p>
