AN-X2-MOD-MON
May 2016
“Railroading” – SYS (or MS) and NET (or NS) LEDs
AN-X2 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 I/O
network.
Debug mode was the mode used in earlier versions of the firmware.
To set debug mode, enter a line with just the keyword LedModeDebug in the
ControlLogix configuration file.
When you autoconfigure the AN-X, it enables debug mode in the file it creates.
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.
