Further information (r047.002 to r047.016)
F069 MLFB data are faulty
(active in all operating states)
Possible fault causes
♦ Excessive EMC-related interference is present
(e.g. due to unprotected contactors, unscreened cables, loose shield connections)
♦ A7009 backplane wiring assembly is defective
Fault value: r047 Index 002 to 016:
1 MLFB code number (r070) = MLFB code number (r070)
is illegal
i002 Incorrect MLFB code number
2 MLFB data checksum error -
3 Works number checksum error -
4 Number of words of MLFB data is incorrect -
10.1.2.13 Communication errors with supplementary boards
F070 SCB1: Serious initialization error
(active in all operating states)
SCB1 and SCI cannot power up correctly (see diagnostic parameter n697 for details)
Fault value:
12 No connection to slave 1
22 No connection to slave 2
F073 SCB1: Current below 4mA minimum value at analog input1 of slave 1
(active in all operating states)
The cause of the fault may be a cable break
F074 SCB1: Current below 4mA minimum value at analog input2 of slave 1
(active in all operating states)
The cause of the fault may be a cable break

1 The "Heartbeat counter“ of the CB/TB has not started to
count within 20 s
i015 Code number of board:
1 TB or 1
st
CB
2 2
nd
CB
2 The product version of the installed CT/TB board is not
compatible with the SIMOREG 6RA70 converter
i002 Code number of slot containing incompatible board:
2 Slot D
3 Slot E
4 Slot F
5 Slot G
6 CB when configuration includes TB
