10.3.4 Event registers
The triggering of an event in trip unit can provide historical data object values at the instance
in time the event occurs occurring around the time of the event. Trip unit categorizes the
event information into classifications to provide various numbers of each type. Modbus
communication can only have the access to obtain historical summary, trip and alarm event
data, as shown:
event type
Historical summary
Historical trip
Historical alarm
Event classification
A single triggering can place information into multiple event types. For example, the occur-
rence of an event triggered by a circuit breaker trip may provide both historical summary and
historical trip information.
Access to event information is based on the selection of event type and event ID. Register
408193 is a R/W register used to select the event type, using function code 06 or 16 to
write. The event information may be read by using function code 03 or 04.
When written event type selection in register 408193, the earliest and latest event ID can be
obtained respectively in register 408194 and 408196 to determine the range of events saved
for the selected event type. Register 408198 is a R/W register used to select the request
event ID and is written with function code 16. If request event exists in trip unit, register
408200 and 408202 provide the Previous event ID and Next event ID. If the requested
event doesn't exist in trip unit, exception code 0 x 87 is returned.
The date and time when request event happened is read in registers 408204 through
408211 using the same date and time description as shown in 0. This value corresponds to
the time of occurrence of the historical event.
Register 408212 provides an indication of the selected event type's data content. This is a
constant value for the three event types Modbus port supports.
