●
Display of RF activity
Indicates whether the reader is sending via the antenna (constant green), whether
transponders were detected by the reader (flashing yellow) and whether a transponder
was sent to the user application (constant yellow).
●
Indication of the quality of the antenna alignment (RSSI)
When aligning the antenna, using the WBM, the status display indicates the RSSI value
with which the transponder was detected. The more LEDs light up (first 3x red, then 3x
yellow, then 3x green), the higher the RSSI value with which the transponder was
detected.
You can find more information on the antenna alignment in the configuration manual
"SIMATIC RF600".

How the LED status display works
Note that the RF615R/RF650R readers do not have an LED status display. The LED status
display displays the error messages of the RF680R/RF685R readers.

LED displays of the RF680R/RF685R readers
Error messages are indicated by red flashing status LEDs and the red flashing "ER" LED. A
distinction is made between hardware errors (faults) and normal errors. With hardware
errors, the LEDs flash with a fast frequency of 4 Hz. With all other errors, the LEDs flash with
a slow frequency of 2 Hz.
The detailed LED error display described here is enabled as default. If required, you can
disable this in the "Settings - General" menu item of the WBM. If the LED error display is
enabled, a separate LED pattern is assigned to every error in the LED status display. The
displayed LED patterns are based on the error code of the hexadecimal error message
converted to binary.
