You can now replace the defective AS-i slave as follows:
Replace the defective AS-i slave with an
identical
AS-i slave with address zero
(default address).
The IE/AS-i LINK now programs this slave with the address of the original slave
you are replacing.
The “AUP” and “CER” LEDs go off.

You will see the corresponding error messages on the display or via WBM.
Table 10-1 Error/fault displays of the LEDs for the IE/AS-i LINK (top right)
“LED” / Fault/error
Possible Cause
Remedy
”SF” lit
IE/AS-i LINK signals remove/in-
sert module interrupts or diagno-
stic information to the PROFINET
IO controller.
Causes: Parameter assignment/
configuration errors on PROFI-
NET or on the AS-Interface.
Check the “SF”, “APF” and “CER”
LEDs in the AS-i line block.
Evaluate the bits in the slave dia-
gnostic information to identify the
error in greater detail.
”BF” LED lit (indicates an error on
LAN attachment)
The connection to the PROFINET
IO controller is interrupted.
Check PROFINET connector on
the PROFINET IO controller and
on the IE/AS-i LINK.
“BF” flashes.
Wrong PROFINET IO controller
mode (STOP).
Check/correct PROFINET IO
controller mode.
The PROFINET device name con-
figured on the PROFINET IO con-
troller does not match that of the
IE/AS-i LINK.
Check/correct PROFINET IO con-
troller configuration.
”ON” LED is not lit
No operating voltage on the
IE/AS-i LINK.
Check the connection of the AS-i
power supply unit and if
necessary replace it.
