Appendix B 1768 EtherNet/IP Module Status Indicators
Flashing red The module detected a recoverable minor fault.
Check the module configuration. If necessary,
reconfigure the module.
Red The module detected an unrecoverable major
fault. Cycle power to the module. If this does not
clear the fault, replace the module.
4 Network Status (NET) Indicates if CIP connections are established.
The 1756-EN2TR and 1756-EN3TR modules do not
have a NET status indicator.
Off One of these conditions exists:
• The module is not powered.
– Verify there is chassis power.
– Verify that the module is completely
inserted into the chassis and backplane.
– Make sure the module has been
configured.
• The module is powered but does not have an
IP address. Assign an IP address to the
module.
Flashing green The controller has an IP address and one of these
conditions exists:
• The module has not established any CIP
connections.
If connections are configured for this module,
check the connection originator for a
connection error code.
• One or more connections have timed out. For
example, an HMI or I/O connection has timed
out.
Reestablish the connection.
Green The module has established at least 1 CIP
connection and is operating properly. The
module’s IP address scrolls across the Module
Status display.
Red The module is in conflict mode. It shares an IP
address with another device on the network. The
module’s current IP address scrolls across the
Module Status display. The display scrolls: OK
<IP_address_of_this_module> Duplicate IP
<Mac_address_of_duplicate_node_detected>
For example: OK 10.88.60.196 Duplicate IP -
00:00:BC:02:34:B4
Change the module’s IP address.
Flashing green/
flashing red The module is performing its power-up testing.
