Chapter 11 - Capturing Alarms and Events

This chapter looks at how the Silver Series uses alarms and events.

Using Alarms

EasyBuilder has three parts that are used to perform alarm functions: the Alarm Scan object, the Alarm Display
object, and the Alarm Bar object. The Alarm Scan object monitors alarm conditions and alerts the Alarm Display
object and the Alarm Bar object when an alarm condition occurs. Use the Alarm Display object if you want to
display a scrollable list of all alarms that are active. Use the Alarm Bar object to display all active alarms on a
single horizontally scrolling line (like a marquee).

Mon i tor ing Alarms with the Alarm Scan Ob ject

The Alarm Scan Object continuously monitors PLC coils to determine if an alarm condition has occurred. Once an
alarm is active, the Alarm Scan Object directs a string of characters associated with that alarm to the Alarm Display
Object and the Alarm Bar Object for display on the OIT screen.
To create an Alarm Scan Object
1. From the Parts menu, click Alarm Scan. Or click the Alarm Scan icon in the Draw toolbar.
The Alarm Scan Object dialog box appears.
You can also use the Alarm Indicator on the Task Bar to determine if any alarms
are active. For more information on using the Alarm Indicator, refer to the section
Using the Task Bar in Chapter 5 "Creating Windows".
