Fundamentals of application planning
4.1.1
Selection criteria for SIMATIC RF200 components
Assess your application according to the following criteria, in order to choose the right
SIMATIC RF200 components:
●
Static or dynamic data transfer
●
Data volume to be transferred
●
Speed in case of dynamic transfer
●
Ambient conditions such as relative humidity, temperature, chemical impacts, etc.
4.1.2
Transmission window and read/write distance
The reader generates an inductive alternating field. The field is strongest close to the reader;
however, a read/write distance of "zero" between reader and transponder is not
recommended.
The field strength of the alternating field decreases quickly in proportion to the distance from
the reader. The distribution of the field depends on the structure and geometry of the
antennas in the reader and transponder
A prerequisite for the function of the transponder is a minimum field strength at the
transponder, which is still barely achieved at distance S
g
from the reader.
The picture below shows the transmission window of the SIMATIC RF210R and
SIMATIC RF220R readers between transponder and reader:
