In addition to the different displays described in Table 8-2 and Table 8-3,
combinations of several LEDs are also possible. Table 8-4 shows you the
meanings of the displays.

Meaning
Remedy
All on
DP/ASi link starting up.
–
All on except ASi
POWER FAIL
A fault has occurred in the PROFIBUS-DP
during start-up.
Check the PROFIBUS-DP, the DP master
and the bus connection.
ASi SLAVE FAIL
flashing
DP/ASi link has not detected an ASi slave.
DP/ASi link not starting.
Check the ASi cable and the cable termina-
tion.
BF flashing
Station number 126 or 127 is set on the DIP
switch block or switch 8 is in OFF position.
Set the correct station number on the DIP
switch block.
Set switch 8 on the DIP switch block to ON
and set a valid station number in the EE-
PROM.
CONFIG ERROR
and all ASi SLAVE
FAIL light
Normal mode: ASi slave 31 has failed
S7 start-up: data record 128 missing
Check your configuration. Possibly no ASi
slaves have been configured.
If several ASi slaves have failed, the failed ASi slave having the lowest ASi
address is indicated with the ”ASi-SLAVE FAIL” LEDs. You recognize the
failure of several ASi slaves by the ”AUTOPROG AV” LED not being on.
Check, therefore, the ASi cable for damage in all cases as well.
If the DP/ASi link detects that an ASi slave has failed or that there is no
longer a connection to it, it takes the following action:
The input data to the DP master are reset to 0 for the failed ASi slave.
A diagnostic message is generated (refer to section 8.2)
All data, including the reset data of the failed ASi slave, are still transmitted
to the DP master.
If you have remedied the reason for the failure, you can establish immedi-
ately whether the DP/ASi link is working properly again. If everything is in
order, the DP/ASi link enters normal operation. Only the ”RUN” LED is on.
