Error Indication (IO LED)
The blink code is repeated cyclically until the error is corrected and/or the
Linux fieldbus coupler is rebooted.
The following table lists the types of errors with the associated blink codes:
Error ar-
gument
Fault Code 1: Hardware and Configuration Fault
Error code 4: Physical error of the internal bus
Error code 6: Node configuration error
Error description
1 Overflow of the internal buffer
memory for the inline code.
4 Error when writing to
EEPROM
5 Fault when reading the serial
EEPROM
6 The I/O module configuration
after an internal bus reset
differs from the one after the
last I/O-IPC start-up.
14 Maximum number of gateway
modules or mailbox modules
exceeded
n* Interruption of the internal bus
behind the nth I/O module with
process data.
8 Error during process image
generation
Remedy
Turn off the supply voltage of the Linux
fieldbus coupler, reduce the number of
modules and turn on the supply voltage again.
If the error remains, replace the coupler
Switch off the supply voltage of the Linux
fieldbus coupler, replace the coupler and
switch on again.
Switch off the supply voltage of the Linux
fieldbus coupler, replace the coupler and
switch on again.
Restart the Linux fieldbus coupler by turning
the power supply off and on again.
Reduce the number of corresponding
modules to a valid number.
Turn off the supply voltage of the Linux
fieldbus coupler, replace the (n+1)th I/O
module with process data and turn on the
supply voltage again.
Reduce the number of I/O modules on the
node
