Sensor (VLX-F231-B6)
Power
The "Power" LED is green: The VLX-F231-B6 interface module is correctly connected to the
power supply.

The "State" LED is green: Data is being exchanged with the sensor(s). The four "Error
No/Select ID" LEDs are used to display the number of the currently polled sensor.
The "State" LED lights up red: The interface module has detected an error or a warning. The
interface module uses the "ErrorNo/Select ID" LEDs to display the binary coded error number
or warning number, and sends the number to the PROFIBUS master via the external diagnostic
byte.
