Table 8.3-2 SLB fault display
♦ B0041: Time out:
Bit = 1 indicates that an interruption has occurred in cyclic data
transfer. This status remains active until cyclic data transfer has
been resumed.
The reaction time is permanently stored in the SLB and cannot be
changed.
Every time "Time out" occurs, the SLB diagnostics parameter (r748,
Index 3) is incremented by the value 1 (→ statistics).
At the same time, the address of the node that has first noticed the
interruption in the ring can be upread in r748, Index 5.
♦ B0040: SLB telegram failure
Bit = 1 indicates that the telegram failure time set in the "SLB
TlgOFF" parameter (P741) has run out in this node, without a valid
SYNC signal having been received.
♦ B0042: Start alarm
Bit = 1 indicates that the SIMOLINK ring is physically open and that
a start cannot be carried out. This status is also signaled by alarm
A002.
Bit = 0 indicates that the SIMOLINK ring is physically closed.
♦ B0043: Drive synchr. (only MC)
Bit = 1 indicates whether the CU is synchronized to the SIMOLINK
BUS. Corresponds to the inverse of alarm A003.
