Self-Diagnosis During Operation

During operation, the SIM continuously monitors itself. If a fault is found, the byteflight  communication is stopped and the power supply of the satellites is switched off by the SIM. (See WATCHDOG FUNCTION  )

The S/E modules are capable of diagnosing the optical signal quality. A warning signal is generated when the optical reception quality falls below a certain threshold. The communication still can function without faults.

The SIM and all the satellites continuously check the VIN received across the byteflight  against the VIN entered in the control units. If there is no match or an entry is missing, the AWL is switched on.
