Chapter 13 - Capturing Alarms and Events

This chapter looks at how the Silver Plus 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/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).

Mon i tor ing 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 OIT screen.
