3.1.7.4 Fault message via the blink code of the I/O LED
Fault argument Fault description Trouble shooting
Fault code 1: Hardware and configuration fault
0 EEPROM check sum fault / check sum
fault in parameter area of the flash
memory Change the fieldbus coupler
1 Overflow of the internal buffer memory
for the inline code Change the fieldbus coupler
2 Unknown data type Change the fieldbus coupler
3 Module type of the flash program
memory could not be determined / is
incorrect Change the fieldbus coupler
4 Fault during writing in the flash mem-
ory Change the fieldbus coupler
5 Fault when deleting the FLASH mem-
ory Change the fieldbus coupler
6 Changed I/O module configuration
found after AUTORESET Change the fieldbus coupler
7 Fault when writing in the serial
EEPROM
8 Invalid firmware
9 Checksum error serial EPROM
10 Initial error serial EPROM
11 Read error serial EPROM
12 Timeout error serial EPROM
Fault code 2: Fault in programmed configuration
n* (n<0, n>65) Incorrect table entry
Change the entry in the configuration for
I/O module n.
Fault code 3: Internal bus command fault
0 I/O module(s) has (have) identified
internal bus command as incorrect. Determine where the module bus has been
interrupted by removing the fieldbus cable.
Plug the end module in the middle of the
node. Switch the coupler off and on again.
If the I/O LED keeps blinking, displace the
end module anew. If there is only one
module left which is connected to the
coupler and if the I/O LED lights up, either
the module or the coupler is defective.
Change the defective component.
Fault code 4: Internal bus data fault
n* (n<0, n>65) Interruption after the nth module Replace the nth module within the node
Fault code 5: Register communication fault
n* (n<0, n>65) Module bus fault during register com-
munication Replace the nth module within the node
Fault code 6: Fieldbus specific fault
0 Fault code 6 is not implemented
Fault code 7: I/O module not supported
n* I/O module not supported at position n
Fault code 8: unused
0 Fault code 8 is not used.
Fault code 9: CPU TRAP error
1 Illegal Opcode
2 Stack overflow
3 Stack underflow
4 NMI
* The number of blink pulses (n) indicates the position of the I/O module. I/O modules
without data are not counted (i.e. supply module without diagnosis)
