3.11.5 Fault Message via Blink Code of the I/O LED
Fault
Argument
Fault Description Remedy
Fault Code 1: Hardware and Configuration Fault
- Check sum fault in
parameter area of the
flash memory.
Switch off the supply voltage of the node.
Replace the coupler and switch on the supply
voltage again.
1 Overflow of the internal
buffer memory for the
inline code.
Switch off the supply voltage of the node. Reduce
the number of modules and switch on the supply
voltage again. In case that the fault still exists,
replace the coupler.
2 Unknown data type Detect faulty I/O module as follows: turn off the
power supply. Place the end module in the middle
of the field bus node. Turn the power supply on
again.
- If the LED is still blinking, turn off the power
supply and place the end module in the middle of
the first half of the node (towards the coupler).
- If the LED doesn't blink, turn off the power
supply and place the end module in the middle of
the second half of the node (away from the
coupler). Turn the power supply on again. Repeat
this procedure until the faulty I/O module is
detected. Replace the faulty I/O module.
Ask about a firmware update for the field bus
coupler.
3 Module type of the flash
program memory could
not be determined / is
incorrect.
Switch off the supply voltage of the node.
Replace the coupler and switch on the supply
voltage again.
4 Fault during writing in
the flash memory.
Switch off the supply voltage of the node.
Replace the coupler and switch on the supply
voltage again.
5 Fault when deleting the
FLASH memory.
Switch off the supply voltage of the node.
Replace the coupler and switch on the supply
voltage again.
6 Changed I/O module
configuration found after
AUTORESET.
Restart the coupler by switching the supply
voltage off and on again.
7 Fault when writing in the
serial EEPROM.
Switch off the supply voltage of the node.
Replace the coupler and switch on the supply
voltage again.
