6.2. Status LEDs of theTPS-1
The TPS-1 uses 4 GPIOs to indicate the device status. These GPIOs can be connected directly to LEDs to display the status.

Description:
LED_BF_OUT Red B13 Bus Communication:
ON
No link status available.
Flashing Link status ok; no communication link to a PROFINET-
Controller.
OFF
The PROFINET -Controller has an active communication link
to this PROFINET -Device.
LED_SF_OUT Red B11 System Fail:
ON
PROFINET diagnostic exists.
OFF No PROFINET diagnostic.
LED_MT_OUT
Yellow
B10
ON
Maintenance required / demanded:
PROFINET diagnostic alarm with maintenance state
required or demanded.
OFF No diagnostic alarm with maintenance state required or
demanded pending.
LED_READY_OUT
Green
C10
Device Ready:
OFF TPS-1 has not started correctly.
Flashing
TPS-1 is waiting for the synchronization of the Host CPU
(firmware start is complete).
ON TPS-1 has started correctly.
The status signals LED_BF_OUT, LED_SF_OUT, LED_READY_OUT and LED_MT_OUT are driven “active low”.
6.3. I2C-Bus – LWL Diagnostic
The TPS-1 provides two “I
2
C Interface Lines” for fiber optics diagnostic purposes. The recommended AVAGO transceiver (AFBR-5978Z) features
internal registers that can be read by the I
2
C interface. The transceiver can deliver diagnostic information via the I
2
C interface. If signal quality is
dropping, an alarm indication can be sent to the controller.
