LEDs
The AN-X4-ABRIO-SCAN has LEDs that indicate the state of the Ethernet connection, the overall
module state and the connection to the remote I/O network.
Ethernet LEDs
There are two LEDs that indicate the state of the Ethernet connection, above the Ethernet connector.
The yellow LED is on if the link is running at 100 Mbits/second and is off otherwise.
The green LED is off if the link is inactive and is on if the link is active. If activity is detected, the
link blinks and continues blinking as long as activity is present.
If the AN-X4 is not connected to Ethernet, both LEDs are off.
MS (Module Status) and NS (Network Status) LEDs
The MS LED is used by the AN-X operating system and software to indicate the state of operations
and errors.
It should be used in conjunction with the logs to locate the cause of problems.
In the following, RED/3 for example means three red flashes followed by a pause.
