Reader is not active, a serious error has occurred. In addition, this LED also indicates |
|
|
|
the fault status through the number of flashing pulses. Reboot (operating voltage Off |
|
|
|
→ On is necessary). |
|
|
|
The LED flashes once for the 'INACTIVE' status, rebooting is not necessary in this |
|
|
|
case. |
For more detailed information on the flash codes of the reader see Chapter Error messages and flash codes for RF620R/RF630R (Page Fehler! Textmarke nicht definiert.)
Note
LED not lit yellow?
If the LED does not light up yellow even though a tag is located within the field, common causes are:
•Incorrect configuration in the init_run command, or init_run command was not executed (see "Configuration Manual RF620R/RF630R")
•Antenna is switched off
•A tag is used, that is not compatible with the reader protocol (EPC Global Class 1 Gen 2).
•Tag is defective
•Reader or antenna has a defect
•Tag is not in the field of radiation of the transmit antenna

Earth (shield) |
The knurled bolt of the M12 plug is not connected to the shield (on the reader side).
Note
You must therefore not use any SIMATIC connecting cables that use the angled M12 plug.

Readers 1.1 RF620R reader
Note
This cable has an 8-pin M12 connector at one end and the other cable end is 'open'. There are 8 color-coded single cores there for connecting to external devices. There are different cable lengths in the product range (3 m to 50 m). Long cables can be reduced if necessary.
Note
For long cables: Adapt supply voltage and data rate accordingly
Note that with long cables in particular, the supply voltage of 24 V DC must always be applied. Note also that the data rate on the serial interface must, if necessary, be reduced. (See "Configuration Manual RF620R/RF630R")
1.1.1.5Grounding connection
The RF620R/RF630R can be electrically connected to the ground potential through a contact washer. The tightening torque must be increased in this case to ensure that electrical contact is made (2.7 Nm).

1.1.2Planning application
1.1.2.1Minimum mounting clearances of two readers
The RF620R has a circular polarized antenna. At 500 mW ERP radiated power, due to the opening angle of the antennas, their fields can overlap considerably. It is no longer possible to clarify in which antenna field access to the data of a tag is performed.
In order to avoid this, always keep a minimum distance of 3 m between two readers with the maximum radiated power of 500 mW ERP.

Dense Reader Mode (DRM)
The readers can also interfere with each other (secondary fields), if the channels (Reader TX, Transponder TX) overlap. In order to prevent a transponder channel overlapping with a reader channel, we recommend that the Dense Reader Mode (DRM) is used.
1.1.2.2Antenna diagram for RF620R (ETSI)
The following radiation diagrams show the directional radiation pattern of the internal antenna of the RF620R (ETSI) reader. For the spatial presentation of the directional radiation pattern, the vertical plane in space (Azimuth section) as well as the horizontal plane (elevation section) must be considered. This results in a spatial image of the directional radiation pattern of the antenna with its main and auxiliary fields.
