Using Events for an Alarm His tory

Events are a complicated feature to understand and it may be a little unclear as to how events can be used. So let's
go through an application example in which we will use the events feature to create and display an alarm history.
The alarm history shows all alarms that may have occurred in the past. The Alarm objects described earlier in this
chapter cannot be used to create a history since the alarm strings are removed from display once the alarm condition
no longer exists. But we may want to know what alarms have occurred in the past even though they no longer exist.
Events can be used for just such a purpose.
For this example, we will use the same alarms that were shown in the section earlier in this chapter that described
using the Alarm Display Object. Therefore, we will create five events which trigger from internal memory coils
LB0-4.
Create five Set Bit Objects to trigger the events
1. Open a new project with the startup screen displayed
2. Create five Set Bit Objects with the following parameters. Refer to Chapter 8 Representing
Data with Graphics Objects if necessary, for more information on how to use the Set Bit part.
