3.5 Troubleshooting

3.5 Troubleshooting
The following sections describe some typical problems and how to address them.
Unable to communicate with the device
See the "Communication faults" section of the previous topic "Faults".
All of the LEDs are off
It is necessary to provide module power via the power terminals on the front of the
ET 200pro EtherNet/IP module The module does not attempt to initialize until power is
applied to the 24 VDC terminals.
Module Status LED is solid red
If a major unrecoverable fault occurs, the device ceases all communication on the network
and the Module Status LED will be solid red. This condition could occur due to a hardware
failure that prevents proper operation of the device. Replace the interface module, or contact
your Siemens representative.
Module Status LED is flashing red
If the Module Status LED is flashing red, this is most likely due to a configuration error. In
automatic configuration mode, this may be due to a module hot swap in which an incorrect
module was used in place of the previous module or a new module has not been inserted. In
user configured mode, this may indicate that an invalid Adapter parameter combination has
been specified or the configuration specified by the module does not match the actual
configuration currently connected to the ET 200pro EtherNet/IP module.
Module Status LED is flashing green
The module configuration is correct, but an invalid parameter combination has been
assigned for either the ET 200pro EtherNet/IP module or one or more other modules.
Network Status LED is solid red
The device fails the duplicate MAC ID check sequence during power-up due to a conflicting
node ID.
To recover, perform one of the following steps:
● If the ET 200pro EtherNet/IP module is using DHCP, change the IP address at the DHCP
server and power cycle the module.
● If you are using a configured IP address, modify one of the IP addresses with the
EIP ET200 Configuration Tool. You may have to disconnect one of the conflicting devices
from the network first.
