ABB RET670 - Introduction

3.15.3.1 Introduction
When using a Substation Automation system with LON or SPA communication, time-
tagged events can be sent at change or cyclically from the IED to the station level.
These events are created from any available signal in the IED that is connected to the
Event function (EVENT). The event function block is used for remote communication.
Analog and double indication values are also transferred through EVENT function.
3.15.3.2 Setting guidelines
The parameters for the Event (EVENT) function are set via the local HMI or PCM600.
EventMask (Ch_1 - 16)
The inputs can be set individually as:
• NoEvents
• OnSet, at pick-up of the signal
• OnReset, at drop-out of the signal
• OnChange, at both pick-up and drop-out of the signal
• AutoDetect
LONChannelMask or SPAChannelMask
Definition of which part of the event function block that shall generate events:
• Disabled
• Channel 1-8
• Channel 9-16
• Channel 1-16
MinRepIntVal (1 - 16)
A time interval between cyclic events can be set individually for each input channel.
This can be set between 0.0 s to 1000.0 s in steps of 0.1 s. It should normally be set to
0, that is, no cyclic communication.
It is important to set the time interval for cyclic events in an optimized
way to minimize the load on the station bus.
