RF600 system planning
4.6 Planning and installation of UHF read points
Dynamic identification
Dead spots cannot be excluded. To be able to compensate for dead spots, we recommend
that you give preference to dynamic identification rather than static identification. Dynamic
identification means that the transponders are read while they are moving (e.g. on the
conveyor belt). If static identification is necessary, the antenna field can e virtually
dynamized with the RF685R antenna or RF680A.
Triggering
To read out all right transponder data, you can have the readers perform permanent
write/read actions or have specific write/read actions triggered. For the following reasons, we
recommend that you trigger specific write/read actions:
● The RFID system only performs write/read actions when an object to be identified enters
the antenna field. This reduces the number of process errors and they can be identified
more quickly.
● Due to the fact that the various RFID systems only perform write/read actions when
necessary, this reduces the possibility of antenna fields disrupting each other. This
increases process reliability in plants, particularly when there is a high reader density.
Decoupling third-party RFID systems
If you are using different RFID systems, make sure that no two systems are active at the
same time or operate separately from each other. Ideally there should be no mixed usage.
Training
Make sure that the engineers commissioning the UHF RFID systems are adequately trained.

Test phase

Metals and absorbent materials have a major influence on the functioning of UHF RFID
systems. Since every environment has different conditions, we recommend that you run a
test with all the objects to be identified for each read point. Include neighboring readers in
these tests as well as scenarios for overshoots. Run through the tests an adequate number
of times to make sure that any sporadically occurring influences on the antenna fields are
also tested.
The final position of the transponder should only be decided after an adequately intensive
test phase so that suitable variations can be tried out if errors occur.
4.6.2.3

Setting up read points

The read point setup described in this section is performed using the Web Based
Management (WBM) and applies to the RF600 readers. You can find a detailed description
of the WBM in the configuration manual "SIMATIC RF600
(https://support.industry.siemens.com/cs/ww/en/ps/15081/man)".
