ETHERNET TCP/IP
Fieldbus status
The health of the ETHERNET Fieldbus is signalled through the top LED
group (‘LINK‘, ‘MS‘, ‘NS‘ and ‘TxD/RxD‘). The two-colored LEDs ‘MS’
(module status) and ‘NS’ (network status) are solely used by the Ethernet/IP
protocol. These two LEDs conform to the Ethernet/IP specifications.

Trouble shooting
Restart the fieldbus coupler by turning the power
supply off and on again. If the error still exists,
please contact the I/O Support.
Check the supply voltage (24V and 0V)
Use an IP address that is not used yet.
Restart the fieldbus coupler by turning the power
supply off and on again and develop a new
connection.
Assign to the system an IP address by BootP,
DHCP or the Ethernet Settings tool.
Check the fieldbus connection.
