16.5.6
Operation principle
The main purpose of the Event function (EVENT) is to generate events when the state
or value of any of the connected input signals is in a state, or is undergoing a state
transition, for which event generation is enabled.
Each EVENT function has 16 inputs INPUT1 - INPUT16. Each input can be given a
name from the Application Configuration tool. The inputs are normally used to create
single events, but are also intended for double indication events.
The EVENT function also has an input BLOCK to block the generation of events.
Events that are sent from the IED can originate from both internal logical signals and
binary input channels. The internal signals are time-tagged in the main processing
module, while the binary input channels are time-tagged directly on the input module.
Time-tagging of the events that are originated from internal logical signals have a
resolution corresponding to the execution cycle-time of the source application. Time-
tagging of the events that are originated from binary input signals have a resolution of
1 ms.
The outputs from the EVENT function are formed by the reading of status, events and
alarms by the station level on every single input. The user-defined name for each input
is intended to be used by the station level.
All events according to the event mask are stored in a buffer, which contains up to
1000 events. If new events appear before the oldest event in the buffer is read, the
oldest event is overwritten and an overflow alarm appears.
Events are produced according to set event masks. The event masks are treated
commonly for both the LON and SPA communication. An
EventMask
can be set
individually for each input channel. These settings are available:
•
NoEvents
•
OnSet
•
OnReset
•
OnChange
•
AutoDetect
It is possible to define which part of the EVENT function generates the events. This
can be performed individually for communication types
SPAChannelMask
and
LONChannelMask
. For each communication type these settings are available:
•
Off
•
Channel 1-8
•
Channel 9-16
•
Channel 1-16
For LON communication, events are normally sent to station level at change. It is also
possible to set a time for cyclic sending of the events individually for each input
channel.
