RF600 system planning
4.3 Antenna configurations
4.3.9 Guidelines for selecting RFID UHF antennas
4.3.9.1 Note safety information
Before planning how to use third-party components, as the operator of a system that
comprises both RF600 components and third-party components, you must comply with the
safety information in Section Safety instructions for third-party antennas as well as for
modifications to the RF600 system (Page 21).
4.3.9.2 Preconditions for selecting RFID UHF antennas
Target group
This chapter has been prepared for configuration engineers who thoroughly understand and
wish to carry out the selection and installation of an external antenna or an external cable for
the SIMATIC RF600 system. The various antenna and cable parameters are explained, and
information is provided on the criteria you must particularly observe. Otherwise this chapter
is equally suitable for theoretical and practice-oriented users.
Purpose of this chapter
This section will help you to select the suitable third-party antenna or the suitable third-party
cable taking into account all important criteria and to make the relevant settings in the
configuration software/WBM of the SIMATIC RF600 system. Correct and safe integration
into the SIMATIC RF600 system is only possible following adaptation of all required
parameters.
4.3.9.3 General application planning
Overview of the total SIMATIC RF600 system and its influencing factors
In the following graphic you can see the design of a SIMATIC RF600 reader with connected
antenna and the influencing factors. The influencing factors affect the radiated power output.
Radiated power = transmit power ± influencing factors
You must be aware of these influencing factors and also consider them if you wish to
integrate third-party components such as antennas or cables into the system. These
influencing factors are described in more detail in sections "Antennas (Page 179)" and
"Antenna cables (Page 54)".
