Evaluating Fieldbus Status

The health of the ETHERNET Fieldbus is signaled through the top LED group
('LINK ACT 1, 2', 'MS', und 'NS').
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.

Meaning
The fieldbus node is connected to
the physical network.
The fieldbus node sends and
receives ETHERNET telegrams
The fieldbus node is not
connected to the physical
network.
Normal operation
The system is not yet configures
The system indicates a not
remediable error
Self test
No system supply voltage
At least one connection
(MODBUS/TCP or EtherNet/IP) is
developed (also connection to the
Message rout applies)
No connection (MODBUS/TCP or
EtherNet/IP).
The system indicates a double
IP-address in the network
At least one connection
(MODBUS/TCP or EtherNet/IP)
announced a Timeout, where the
controller functions as target.
Self test
No IP address is assigned to the
system.
Solution
-
-
1. Check the fieldbus cable.
-
-
1. Restart the device by turning the
power supply off and on again.
2. If the error still exists, please
contact the I/O support.
-
1. Check the supply voltage.
-
-
1. Use an IP address that is not used
yet.
1. Restart the device by turning the
power supply off and on again.
2. Develop a new connection.
-
1. Assign to the system an IP address
for example by BootP or DHCP.
