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/Event Log object, the Alarm Display

object, and the Alarm Bar object. The Alarm/Event Log 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).

Monitoring Alarms with the Alarm (Event) Log

The Alarm/Event Log 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 HMI screen.

To create an Alarm/Event Log:

1. From the Objects menu, select Alarm > Alarm (Event) Log, or click the Alarm (Event) Log icon in the PLC

toolbar. The Alarm(Event) Log dialog box appears.
