12.6 Sequential of events
12.6.1 Functionality
Continuous event-logging is useful for monitoring the system from an overview
perspective and is a complement to specific disturbance recorder functions.
The sequential of events logs all binary input signals connected to the Disturbance
report function. The list may contain up to 1000 time-tagged events stored in a FIFO-
buffer.
12.6.2 Function block
The Sequential of events has no function block of it’s own.
12.6.3 Signals
12.6.3.1 Input signals
The Sequential of events logs the same binary input signals as configured for the
Disturbance report function.
12.6.4 Operation principle
When a binary signal, connected to the disturbance report function, changes status, the
sequential of events function stores input name, status and time in the sequential of
events in chronological order. The list can contain up to 1000 events from both internal
logic signals and binary input channels. If the list is full, the oldest event is overwritten
when a new event arrives.
