Information and Alarm Windows

Chapter 7

7-37

PLC Controlled QTY/Time Reset is enabled, and the PLC controller

resets the counts. The reset occurs when the PLC Controlled Reset bit
changes from 0 to 1. Alarm monitoring continues even though the bit is
on

When off-line to the PLC controller, the PanelView terminal stops
monitoring alarm time and quantity. In this case, “off-line” means:

the PanelView terminal is disconnected

the PanelView terminal is in Configuration mode

the PLC controller is not in Run mode

the PLC controller has the PanelView terminal Remote I/O racks

disabled

When the terminal goes back on-line, the alarm counts are increased by
one for those alarms already listed that are currently in-alarm, and the
times continue accumulating.

The Alarm Status screen can hold up to 496 alarm messages, but only 16
messages can fit on the screen. Use the PgUp and PgDn buttons to scroll
through the alarm messages.

IMPORTANT: In order to be displayed in the Alarm Status screen,
alarms must have messages defined, and be of the bit data type.

Configuring the Alarm Status Screen

To configure the Alarm Status screen, choose Windows in the File menu,
then choose Alarm Status, and set the required parameters.

You can define its screen number, its colors, and whether the alarm count
(QTY) and total time in-alarm (TIME) of all messages can be reset to 0 by
the PLC controller and/or the Alarm Status screen’s QTY/TIME Reset
button. You can also enable the QTY/TIME Reset to PLC Controller
button to indicate when an Alarm Status QTY/TIME Reset has occurred.

You must assign the Alarm window control address to the bit data type,
otherwise the Alarm Status screen will not be displayed. For more
information, see the section on bit position data type for the Alarm
Window earlier in this chapter.

The Alarm Status screen can be accessed via:

a “Go to Screen” button
