S
a
Operating distance between transponder and reader
Secondary fields
In addition to the transmission window, there are also secondary fields whose size is
generally smaller than that of the transmission window; the shape and size of the secondary
fields, depends among other things on the metallic environment. Secondary fields should not
be used in configuring.

See limit distance
Static mode
In static mode the transponder is positioned at a fixed distance (maximum: limit distance)
exactly above the read/write device.

See transponder
Telegram cycles
The transfer of a read or write command takes place in three cycles, known as frame cycles.
1 or 2 bytes of user data can be transferred with each command. The acknowledgement
transfer (status or read data) takes place in 3 further cycles.
Transmission distance
Distance between communication module (read/write device) and transponder (mobile data
storage unit)
Transmission window
Area in which reliable data exchange between transponder and read/write device is possible
due to a particular minimum field strength.
Transponder
An invented word from transmitter and responder. Transponders are used on the product,
the product carrier, the object, or its transport or packaging unit, and contain production and
manufacturing data, i.e. all application-specific data. They follow the product through
assembly lines, transfer and production lines and are used to control material flow.
Because of their wireless design, transponders can be used, if necessary, at individual work
locations or manufacturing stations, where their data can be read and updated.
