Correct any invalid data in the configuration for proper module operation. When
the configuration contains a valid parameter set, all the bits in the configuration
word will be clear. This does not indicate that the configuration is valid for the
user application. Make sure each parameter is set correctly for the specific
application.
4.9.2 Ethernet LED Indicators
LED State Description
Off No activity on the Ethernet port. Data
Green Flash The Ethernet port is actively transmitting or receiving data.
Off No physical network connection is detected. No Ethernet
communication is possible. Check wiring and cables. Link
Green Solid Physical network connection detected. This LED must be on
solid for Ethernet communication to be possible.
4.9.3 Clearing a Fault Condition
Typically, if the OK LED on the front of the module turns red for more than ten
seconds, a hardware problem has been detected in the module, or the program
has exited.
To clear the condition, follow these steps:
1 Turn off power to the rack
2 Remove the card from the rack
3 Verify that all jumpers are set correctly
4 If the module requires a Compact Flash card, verify that the card is installed
correctly
5 Re-insert the card in the rack and turn the power back on
6 Verify the configuration data being transferred to the module from the
ControlLogix processor.
If the module's OK LED does not turn green, verify that the module is inserted
completely into the rack. If this does not cure the problem, contact ProSoft
Technology Support.
