Panel Name

fwAlarmHandlingScreen.pnl

Introduction

This screen is used to show alarms in your PVSS system.

Instructions

This panel allows you to view the alarms in your system. You can choose to view all current alarms, filter alarms on certain criteria and/or show historical alarms between two given times.

The alarm screen shows the table of alarms that match the current filter and gives a count of how many alarms are displayed and how many are unacknowledged.

At the top left of the screen, there are facilities to acknowledge alarms in the table and to print the contents of the table.

Filtering Alarms

To filter the alarms you see, you should click the edit button in the "Alarm Filters" section of the panel. A new panel will load and it is here that you can enter criteria in the filter fields. The following text pattern based filters can be applied:

  • Device Name
  • Logical Name
  • Device Type
  • Device Description
  • Alert Text

To clear all filtering, you can simply press the red cross button in the "Alarm Filters" section of the panel.

Filter Modification (in separate panel)

The "*" in the fields means that the criteria will not be taken into account when filtering - i.e. everything meets the "*" criteria.

In addition you can also filter on system names and alarm severity. To change the systems being viewed you can click in the "Systems" box that shows the current systems being displayed. A new panel will open, allowing you to choose the systems you want to view.

To filter out alarms of certain severities, you can press the "W" (Warning), "E" (Error) and "F" (Fatal) buttons. When these have a dark background, they will be shown. When they have a light background, they will be filtered out and not shown.

Datapoint names and aliases can also be a list of space-separated items, i.e. "*temperature *channel*".

Alarms defined as Global or Local can be filtered using the combo box "Global/Local Alarms".

Once the desired filter has been entered, you must press the button with the green tick to apply the filter and see the results. You can also press the button marked with a red cross to remove all the filters and update the screen accordingly.

It is possible to save and load filters. Pressing the button marked with a disk will open a panel and you can choose a name to save the current filter as. Pressing the button marked with a folder will open a panel where you can choose a saved filter to show in the screen. When you load a filter, you will need to press the green tick button to apply the newly loaded filter.

Current/Historical Alarms

You can choose to view either current alarms or historical alarms. If you choose to see historical alarms, you will need to choose a time range for which you want to see in the history. Once you have chosen the mode (current or historical) you must press the green tick to apply this change to the alarm screen.

Clicking on Manage Display..., you can specify the maximum amount of historical alarms to be displayed.
