Fault Message Via The Blink Code Of The I/O Led - WAGO LONWORKS 750-319 Manual

3.1.7.4 Fault message via the blink code of the I/O LED

Fault argument
Fault code 1: Hardware and configuration fault
Fault code 2: Fault in programmed configuration
Fault code 3: Internal bus command fault
Fault code 4: Internal bus data fault
Fault code 5: Register communication fault
Fault code 6: Fieldbus specific fault
Fault code 7: I/O module not supported
Fault code 8: unused
Fault code 9: CPU TRAP error
* 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)

Fault description
0 EEPROM check sum fault / check sum
fault in parameter area of the flash
memory
1 Overflow of the internal buffer memory
for the inline code
2 Unknown data type
3 Module type of the flash program
memory could not be determined / is
incorrect
4 Fault during writing in the flash mem-
ory
5 Fault when deleting the FLASH mem-
ory
6 Changed I/O module configuration
found after AUTORESET
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
n* (n<0, n>65) Incorrect table entry
0 I/O module(s) has (have) identified
internal bus command as incorrect.
n* (n<0, n>65) Interruption after the nth module
n* (n<0, n>65) Module bus fault during register com-
munication
0 Fault code 6 is not implemented
n* I/O module not supported at position n
0 Fault code 8 is not used.
1 Illegal Opcode
2 Stack overflow
3 Stack underflow
4 NMI

Change the entry in the configuration for
I/O module n.
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.
Replace the nth module within the node
