2.5.2 Event types
Events will be created by the relay under the following circumstances:
• Change of state of output contact
• Change of state of opto input
• Protection element operation
• Alarm condition
• Setting change
• Password entered/timed-out
• Fault record (Type 3 Courier Event)
• Maintenance record (Type 3 Courier Event)
2.5.3 Event format
The send event command results in the following fields being returned by the relay:
• Cell reference
• Timestamp
• Cell text
• Cell value
The menu database contains a table of the events created by the relay and indicates how
the contents of the above fields are interpreted. Fault records and maintenance records will
return a Courier Type 3 event, which contains the above fields together with two additional
fields:
• Event extraction column
• Event number
These events contain additional information that is extracted from the relay using the
referenced extraction column. Row 01 of the extraction column contains a setting that allows
the fault/maintenance record to be selected. This setting should be set to the event number
value returned within the record; the extended data can be extracted from the relay by
uploading the text and data from the column.
2.5.4 Manual event record extraction
Column 01 of the database can be used for manual viewing of event, fault, and maintenance
records. The contents of this column will depend on the nature of the record selected. It is
possible to select events by event number and to directly select a fault record or
maintenance record by number.
Event Record Selection (Row 01) - This cell can be set to a value between 0 to 511 to select
which of the 512 stored events is selected, 0 will select the most recent record; 511 the
oldest stored record. For simple event records, (Type 0) cells 0102 to 0105 contain the event
details. A single cell is used to represent each of the event fields. If the event selected is a
fault or maintenance record (Type 3) then the remainder of the column will contain the
additional information.
Fault Record Selection (Row 05) – This cell can be used to directly select a fault record
using a value between 0 and 4 to select one of up to five stored fault records. (0 will be the
most recent fault and 4 will be the oldest). The column will then contain the details of the
fault record selected.
