Intended usage
Use this object to receive information concerning a circuit-
breaker event (e.g. trip) which has occurred relating to
• Alarms,
• Trip conditions,
• Status of the phases,
• Fault states.
By saving 10 diagnosis records, the time up to a trip can also
be successfully diagnosed.
Addressing and length of the object
Please use the following information for addressing of the
object:
• API is equal to 0 (only required for class 2 DPV1 master),
• Slot number is equal to 0,
• Index is equal to the following:
– 1 for diagnosis record 1,
– 2 for diagnosis record 2,
– 3 for diagnosis record 3 to
– 10 for diagnosis record 10.
The length of the data to be read is 27 Octets. Please ensure
that you do not enter smaller lengths when calling the Read
service as otherwise you will receive a fault indication.
h
If no data exists in the circuit-breaker for an addressed
diagnosis record, because the number of saved events is
less than the selected number, the “resource unavailable”
fault indication (fault code C3 hexadecimal) is generated
as an answer.
