Functions of the LED status display (RF680R/RF685R)
With the LED operating display, you can read out the various operating statuses of the
readers. The LED status display of the RF680R and RF685R readers has several functions.
Among other things, the status display provides the following functions:
●
Startup of the reader
The startup process of the reader is displayed by a status bar lit yellow. As soon as the
startup is completed, the reader requires several seconds before it is operational. This
phase is indicated by a status bar flashing yellow. During a firmware update, the startup
takes longer.
The reader is ready for operation when the "R/S" LED is lit/flashes green. If the "R/S"
LED is flashing, the reader is waiting for a connection. If the "R/S" LED is lit constantly,
the reader is connected to the controller or PC.
●
Error display
If there is an error, the actual error is indicated by the lighting/flashing pattern. The "ER"
LED of the LED operating display also flashes. You will find more information on error
messages in the section "XML/PLC error messages (Page 473)".
●
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".
