8 Diagnosis
8.3 LEDs on the master module
The diagnostic LEDs on the master module are all accommodated on the front
plate. The basic functions of the module are checked when it is switched on.
If no faults are detected, “SC” flashes green after approx. 5 seconds. “HF”
goes out when the drivers are activated.
The state of the Interbus is indicated by other LEDs:
INST_AUTO_RESTART 0x4000 This status bit indicates that the driver should
cyclically attempt to restart the bus in the case
of a bus error. The bus is thus automatically
restarted once the error has been rectified.
INST_DOING_SHUTDOWN 0x8000 This status bit indicates that the driver is being
shut down. This bit is only set in addition to all
the others and serves to provide information for
other functions (e.g. IOCTL) that must be ter-
minated.
