supply The LED lights up to indicate that there is a
supply voltage to the interface driver.
LED2
(green) PROFIBUS data
exchange Shows the status of data exchange for cyclic
data exchange.
LED3
(yellow) PROFIBUS diagnosis The LED is lit if there is an internal error. The
measurement data may be invalid.
LED4 (red) PROFIBUS error The LED lights up if there is an bus error. Pos­
