Planning an RF200 IO-Link system
4.2 Field data of transponders and readers
Minimum distance from reader to reader
All values are in mm
NOTICE
Effect on inductive fields by not maintaining the minimum distances of the readers
If the values fall below those specified in the "minimum distance from reader to reader",
there is a risk of the function being affected by inductive fields. In this case, the data
transfer time would increase unpredictably or a command would be aborted with an error.
Adherence to the values specified in the "Minimum distance from reader to reader" table is
therefore essential.
If the minimum clearance cannot be maintained due to the construction, the HF field
(antenna) of the reader can be turned on or off via the process image (PIQ).
