of the individual abbreviations are shown in the following:
Status Bits Meaning
TOUT TIMEOUT-ERROR the device has detected a skipped timeout supervision
time because of rejected PROFIBUS telegrams. It's an indication of bus
short circuits while the Master interrupts the communication. The numbers
of detected timeouts are fixed in the statistic bus information variable. The
bit will be set when the first timeout was detected and will not be deleted.
NRDY HOST-NOT-READY-NOTIFICATION shows if the application is ready or
not. If this bit is set, the application is not ready to receive data.
EVE EVENT-ERROR the device has detected bus short circuits. The numbers of
detected events are fixed in the statistic bus information variable. The bit
will be set when the first event was detected and will not be deleted.
FAT FATAL-ERROR because of heavy bus error, no further bus communication
is possible.
