Error code 4 "Physical error, internal bus"
Error
argument
Error description
Solution
6. LED continues to flash?
Switch off the power and plug the end module
into the middle of the first half of the node
(toward the controller).
LED not flashing?
Switch off the power and plug the end module
into the middle of the second half of the node
(away from controller).
7. Turn on the power supply again.
8. Repeat procedure 6 and 7 (while halving the step
size) until the faulty bus module is detected.
9. Replace the faulty bus module.
10. If there is only one bus module left and the LED
continues to flash, then either this module or the
controller is defective. Replace the faulty
component.
n*
Interruption of the
internal bus behind the
nth bus module with
process data.
1. Turn off the supply voltage of the node, replace
the (n+1)th bus module with process data and
turn on the supply voltage again.
Error code 5 “Initialization error internal bus”
Error
argument
Error description
Solution
n*
Error in register com-
munication during inter-
nal bus initialization.
1. Switch off the power for the node.
2. Exchange the nth bus module with process data.
3. Turn on the power supply again.
Error code 6 " Node configuration error "
Error
argument
Error description
Solution
1
Invalid MAC ID
1. Switch off the power for the node.
2. Replace the bus coupler.
3. Turn on the power supply again.
2
Initialization error
ETHERNET hardware
1. Restart the fieldbus coupler by turning the power
supply off and on again.
2. If the error remains, replace the fieldbus coupler.
3 Initialization
error
TCP/IP stack
1. Restart the fieldbus coupler by turning the power
supply off and on again.
2. If the error remains, replace the fieldbus coupler.
4 Network
configuration
error (no IP address)
