Maximum number of readable tags

The maximum number of readable tags depends on the following parameters:
● Size of the antenna field
● Readability of the tags
For a transmit power of 500 mW ERP, the following is read when the tag RF620T is used:
● Max. 40 tags in the antenna field (tags perpendicular to antenna at 1 m distance). If 2
antennas are used, up to 80 tags can be recognized.
● Max. 18 tags per second
Note for 2-antenna operation
● If 2 antennas are connected to the SIMATIC RF630R, the antennas must be controlled
using the SET-ANT command.
● If 2 antennas are configured as a gate, both antennas should be simultaneously switched
on with the SET-ANT command. The reader multiplexes both antennas internally. The
multiplexing time is 100°ms (internal read time per antenna).
