modules.
Table 10 - Module Status (MS) Indicator
State Status Description Recommended Action
Off No power or autobauding No power is applied to the DeviceNet connector. Apply power to this connector.
Solid green Normal operation The module is operating normally. None.
Solid red Unrecoverable fault The module has detected an unrecoverable fault. Cycle power to the module. If the anomaly persists, replace the
module.
Flashing green Module needs commissioning
due to missing, incomplete,
or incorrect configuration Module is unconfigured. Reconfigure the module. For additional information, inspect the
Network Status (NS) indicator.
Flashing red Recoverable fault The module detected a recoverable fault. Cycle power to the module or reset the module.
User-initiated firmware
update User-initiated firmware update is in progress. Wait for the firmware update to complete.
Flashing red and
green Device in self test The module is performing its power-cycle diagnostic tests. Wait for the module to complete its power-cycle diagnostics.
Table 11 - Network Status (NS) Indicator
State Status Description Recommended Action
Off Module not online or
no power The module is not online with the network. Verify your network.
Flashing green Module online with no
connections in established
state The module identified the communication rate of the network
but no connections are established. Verify your network and module configuration.
Solid green Module online with
connections in established
state The module is operating normally. None.
Flashing red One or more I/O connections
in timed-out state The module detected a recoverable network fault. Verify your network and module configuration.
User-initiated firmware
update User-initiated firmware update is in progress. Wait for the firmware update to complete.
Solid red Critical link failure The module detected an error that prevents it from
communicating on the network. Cycle power to the module. If the anomaly persists, replace the
module.
Flashing red and
green Communication faulted
module The module detected a network access error and is in
communication faulted state. The module has received and
accepted an Identity Communication Faulted Request-long
protocol message. Verify your network and module configuration.
