AS-i Bus Diagnostics

AS‐i Bus Visual Diagnostics

When a fault occurs on the AS-i bus, the I/O LED on the gateway remains lit as long as this fault remains present. The cause of the fault may be:

Missing power supply: when the AS-i power supply is not present, all LEDs of slaves expected in the reference configuration flash whatever operating mode the TBX SAP 10 is in,
Slave present at address 0: when a slave with the address 0 is connected to the AS-i bus, the LED 0 of the left-hand row flashes whatever operating mode the TBX SAP 10 is in,
AS-i bus configuration fault: whatever operating mode the TBX SAP 10 is in, it constantly compares the real configuration of the AS-i bus with the reference configuration. When a slave is removed or is missing from the AS-i bus, the LED for the address concerned flashes whatever operating mode the TBX SAP 10 is in. When a slave whose profile differs from the one in the reference configuration is installed on the AS-i bus, the LED for the address concerned lights up if the TBX SAP 10 is in configuration mode (in this case, the slave is still activated), and flashes if the TBX SAP 10 is in protected mode (in which case, the slave is not activated).
