Transponder

Forming effective ranges and zones with transponders
Transponders form effective ranges and zones. Effective ranges and zones are defined by
the maximum distance from one or more transponders.
Effective ranges
You can define effective ranges in your system.
An effective range is the range in which sections of the system, for example a machine, can
be operated with the enabling buttons of the HMI device.
