6.4 Guidelines for selecting RFID UHF antennas
● Selection of third-party components:
you wish to select appropriate third-party components for the SIMATIC RF600 system and
to subsequently configure the reader for these components.
● Configuration of existing third-party components:
you already have third-party components (antenna, antenna cable or both) and wish to
appropriately configure the reader for these components.
Procedure for selecting third-party components
Always proceed in the following order during your considerations and the practical
implementation:
1. Consider which third-party components you wish to use in the SIMATIC RF600 system.
2. Depending on the third-party component required, refer either to Section Antennas
(Page 185) or Section Antenna cables (Page 196) for the important criteria for selection
of your components. The selection criteria/parameters are sorted in descending relevance.
3. Use the specified equations to calculate your missing parameters, and check whether the
required values are reached (e.g. antenna gain) and that important secondary values (e.g.
cable loss) are not exceeded or undershot.
4. Configure the reader with the parameters of your third-party components. You can usually
carry this out in the SIMATIC RF660R configuration software. The exact procedure is
described in Section .
5. For advanced users or in exceptional cases, e.g. input of an antenna gain <4.0 dBi), it is
recommendable to carry out the configuration directly using XML commands. For further
information, refer to Section .
Procedure for configuration of existing third-party components
If you already have third-party components which you wish to integrate into the SIMATIC
RF600 system, proceed as follows:
1. Depending on the third-party component, refer either to Section "Antennas" or Section
"Antenna cables" for the important criteria of your components. The parameters are sorted
in descending relevance.
2. Compare the limits with the data of your antenna or cable vendor.
3. Subsequently proceed exactly as described above in "Procedure for selecting third-party
components" from Paragraph 3. onwards.
