Introduction

Continuous event-logging is useful for monitoring the system from an overview
perspective and is a complement to specific disturbance recorder functions.
The event list logs all binary input signals connected to the Disturbance report
function. The list may contain up to 1000 time-tagged events stored in a ring-buffer.

Principle of operation

When a binary signal, connected to the disturbance report function, changes status,
the event list function stores input name, status and time in the event list 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.
