“Railroading” – SYS (or MS) and NET (or NS) LEDs
AN-X alternates (railroads) flashing the SYS (or MS) and NET (or NS) LEDs to indicate
its state.
It railroads the LEDs yellow while it is copying new maintenance or production firmware
files from the microSD card to flash memory.
It railroads the LEDs green for 20 to 30 seconds as it starts production mode.
MS and NS LEDs: Runtime
IMPORTANT!
There are two possible runtime LED modes.
Standard mode is the new default mode and is compliant with the
Ethernet/IP specification.
Debug mode provides more information about the state of the remote I/O
network.
To set debug mode, enter a line with the keyword LedModeDebug in the ControlLogix
configuration file.
When you autoconfigure the AN-X, it sets debug mode in the file it creates.
IMPORTANT!
The AN-X enters debug mode only if the ControlLogix configuration
succeeds.
Standard Mode
The MS and NS LEDs are used by the AN-X operating system and software to indicate
the state of operations and errors.
In standard mode, the MS and NS LEDs should be used in conjunction with the logs to
locate the cause of problems.
