Table 7 Fault identification
Fault list
Use DVT to access the Fault list. If you don’t have DVT you can use any configuration tool as
follows:
1. Object 5300
h
gives information about all active faults. Read sub-index 1 to get the number
of active faults. Write to sub-index 2 to select one of the active faults (0 = highest priority)
and read back sub-index 3 to read the fault ID at that index.
3. Object 5610
h
can be used to read a text description of the fault. Write the fault ID to sub-
index 1 and read back the fault description from sub-index 2.
