Status Indicators Appendix A
Network Channel Indicators
These are the ControlNet network channel indicators.
Channel B is only labelled on the 1769-L35CR controller. The 1769-L32C
controller only has channel A but uses the second indicator in some status
indicator patterns as described below.
EtherNet/IP Indicators
The EtherNet/IP indicators are only on 1769-L32E and 1769-L35E controllers.
Module Status (MS) Indicator
These are the EtherNet/IP module indicators.
Indicator Condition Recommended Action
Off A channel is disabled. Program network for redundant media, if necessary.
Steady green Normal operation is occurring. Normal operation - No action is required.
Flashing green/off Temporary network errors have occurred. 1. Check media for broken cables, loose connectors, and missing
terminators.
2. If condition persists, refer to the ControlNet Planning and Installation
Manual, publication 1786-6.2.1.
The node is not configured to go online. Make sure the network keeper is present and working and the selected
address is less or equal to the UMAX
(1)
.
Flashing red/off Media fault has occurred. 1. Check media for broken cables, loose connectors, and missing
terminators.
2. If condition persists, refer to the ControlNet Planning and Installation
Manual, publication 1786-6.2.1.
No other nodes are present on the network. Add other nodes to the network.
Flashing red/green The network is configured incorrectly. Reconfigure the ControlNet network so that UMAX is greater than or equal
to the card’s node address.
Off You should check the MS indicators. Check the MS indicators.
Steady red The controller is faulted. 1. Cycle power.
2. If the fault persists, contact your Rockwell Automation representative
or distributor.
Alternating red/green The controller is performing a self test. Normal operation - No action is required.
Alternating red/off The node is configured incorrectly. Check the card’s network address and other ControlNet configuration
parameters.
(1) UMAX is the highest node address on a ControlNet network that can transmit data.
Indicator Condition Recommended Action
Off The controller does not have power. Check the controller power supply.
Flashing green The port is in standby mode; it does not have an IP address and is operating
in BOOTP mode.
Verify that the BOOTP server is running.
Steady green The port is operating correctly. Normal operation - No action is required.
Steady red The controller is holding the port in reset or the controller has faulted. 1. Clear the controller fault.
2. If the fault will not clear, replace the controller.
The port is performing its power-up self test. Normal operation - No action is required.
A nonrecoverable fault has occurred. 1. Cycle power to the controller.
2. If the fault will not clear, replace the controller.
Flashing red The port firmware is being updated. Normal operation - No action is required.
