Figure 1 shows an example of the Alarms Page where the [[Alarm System]] is enabled and no alarms are triggered. The page displays information from the

[[/Alarms ODB tree]].

At the top of the Alarms page are two buttons,

Purpose

The purpose of the mhttpd Alarms page is to display information about the MIDAS Alarm System, and to allow the user to reset individual alarms or all alarms.


Access the Alarms page

The Alarms Page is accessed from the Status Page (or any of the other Pages) by clicking on the menu-button Alarms. The top level ODB trees will be visible as key-links (i.e.links to a key) (Figure 1).



Features of the Alarms page

Figure 1: Alarms page example
Figure 2: Alarms page with Alarm system disabled
Figure 3: Demo ODB alarm subtree
Figure 4: Caution class alarms subtree

Figure 1 shows an example of the Alarms Page where the Alarm System is enabled and no alarms are triggered. The page displays information from the /Alarms ODB tree. At the top of the Alarms page are two buttons, Reset all alarms and Alarms on/off. The latter button will disable/enable the Alarm System. If the Alarm system is disabled, it will appear as in Figure 2.


The Alarms Page is divided into four areas, one for each of the alarm types :

Program
Periodic
Evaluated
Internal

Clicking on one of the alarm-links on the left hand side of the page (under heading Alarm) switches to the ODB Page displaying the contents of the /Alarms/Alarms/<alarm-name> subtree. For example, Figure 2 shows the Demo ODB alarm subtree.

In Figure 1, under heading State, the Demo ODB is shown as  Disabled  because the ODB key Active for that alarm is set to "n". Alarms with this key set to "y" are shown as   OK  .

The class for each alarm is shown as a link under the Class heading. Clicking on one of the class-links switches to the ODB Page displaying the contents of the /Alarms/Alarms/<class-name> subtree. For example, Figure 4 shows the "Caution" class subtree.


The Condition reflects the contents of the ODB Condition key for that alarm.

The Current value for Evaluated alarms displays the current value of the Condition. In the case of Alarm Demo ODB, this is the current run number.


Figure 5: Alarms page example with an alarm triggered



Figure 5 shows an example of the Alarms page with the alarm pol_fevme is  Triggered . This causes an alarm banner to appear on the Status Page (see Alarm Banner).
