LEDs Meaning
*
ON Lights up when the RF180C has completed start-up without errors.
24 VDC Lights up when the 24 V supply voltage is connected to the RF180C.
ACT_1, ACT_2 The corresponding reader/SLG is active in processing a user command.
ERR_1, ERR_2 * A flashing pattern indicates the last error to occur.
PRE_1, PRE_2 ** Indicates the presence of a tag/MDS.
RxD_1, RxD_2 Indicates live communication with the reader / SLG. May also indicate malfunctions on the
reader / SLG.
*) The meaning of the individual flash patterns and the associated fault descriptions can be found in the relevant FB
documentation.
**) In multitag mode, this LED uses a flash interval to indicate the number of data media currently within the range of
influence of the reader/SLG.

BF SF Cause of error Error handling
On –
• Communication module is in
start-up mode.
• No cable inserted
When the bus is configured correctly, this state ends
a few seconds after switching the module on.
Flashes -
• There is no connection to the
PROFINET IO controller.
• Check the PROFINET IO connection.
• Check your PROFINET IO configuration (device
name, GSDML file).
• Reload the configuration into the RF180C (see
the Section "Configuration parameters of the
RF180C")
Off On
• A PROFINET diagnostic signal
exists.
• Analyze the diagnostic data.
Off Off
• Normal mode
On Flashes for 10
seconds after
switching on
The firmware has set the MAC addresses 2 and 3 to the default setting. This happens
only if the module was updated from Version 1 to Version 2.
– = Status not relevant
