| == Features of the Custom Status Page ==
| |
| The Custom Status Page provides status information specific to the {{bnmqr|join=or}} experiments. The option of reverting to the MIDAS standard status page is provided via the ToggleStatusPage button.
| |
| | |
| === Command and Page Buttons ===
| |
| | |
| [[Image:Bnqr_top_buttons2.png|Figure 3 Command and Page Buttons]]
| |
| <br clear=all>
| |
| In the middle of the top line on the Custom Status page are found the standard [https://midas.triumf.ca/MidasWiki/index.php/Status_Page#Menu_Buttons Menu buttons] to stop and start runs or to display
| |
| different MIDAS pages. These standard buttons appear on most MIDAS pages (see [https://midas.triumf.ca/MidasWiki/index.php/Status_Page MIDAS Status page] for more information).
| |
| | |
| Below these buttons are buttons specific to the {{bnmqr|join=and}} experiment. Some are [[BNMR: Perlscripts#Customscripts|customscript buttons]], that is, a script is run when the button is pressed. Others switch to a different custom page. The actions of these buttons are described in Table 1.

After refreshing the page, the MIDAS status page will appear.

A message can be seen at the top of the custom page in this case "Using alias link "CustomStatus&" from Midas Main Status Page". To revert to running this page as the Custom Status Page, press the button once more and refresh the page.

| === Page Update Information ===
| |
| The page update information is also visible in Figure 1. The custom status page updates completely with a full page reload every minute. In between, it updates the information using innerHTML. This is called a partial reload. The time between partial reloads can be set by the user by clicking on the link "Page update 10 sec (min 5s)" (Figure 1). This minimum time is 5s. The ODB data is read each time a partial reload is done. The times of the last ODB data read, last full reload etc are also shown in Figure 1. A countdown to the next full reload is also visible.
| |
| | |
| === Status Line ===
| |
| The Status lines on the Custom Status Page show the status of the run and some of the important settings (Figure 4).

| |

| |
| <br clear=all>
| |
| The first line shows the selected PPG Mode. This changes when the mode is changed by pressing one of the PPG Mode buttons. The run number (Table 2) is shown in different colours for a '''test''' or '''real''' run (see [[BNMR: Run numbering]]).

| |
| The run state is shown in different colours depending on the run state (Table 3). The time the run started is shown and, if running, the run duration, otherwise the time the run stopped.
| |
| The next line shows the Status, which may show an information message. Below this is a line showing the directory of the saved files.
| |
| | |
| Next are a number of boxes showing important settings (Table 4). Most are provided with a checkbox so the user can change the values from the custom status page.

| |
| ;NOTE
| |
| :When '''real''' data is being taken (i.e. the run mode is set to '''real''' ), this line should
| |
| look similar to Figure 4, with Alarms Active, Helicity Check, Helicity Flip and Single/Dual Mode Switch Check all being enabled.
| |
|
| |
|
| === Logging/Threshold/Helicity === | | == Implementation == |
|
| |
|
| === Last Midas Message ===
| | We force Midas to use our custom status page by deleting the file <code>$MIDASSYS/resources/status.html</code> with a symlink to <code>bnxr_common/custom/status.html</code> from the bnmr repository. |
|
| |
|
| ===Frontend Scalers===
| | The page uses [https://daq00.triumf.ca/MidasWiki/index.php/Mjsonrpc Midas JRPC] calls to talk to: |
| | * the <code>mode_changer.py</code> program for changing modes and changing between real/test runs |
| | * the <code>rf_calculator_fe.py</code> program for visualizing the PPG and PSM settings as plots |
|
| |
|
| === Histogram Stats ===
| | The page uses standard [https://daq00.triumf.ca/MidasWiki/index.php/Custom_Page Midas custom page] tools for editing ODB settings. An ODB hotlink is used for the neutral beam re-referencing. |
|
| |
|
| === Select PPG and Run Mode === | | == Example screenshot == |
| This line on the Custom Status Page contains the PPG Mode change and Run Mode buttons (Figure 5).

| <br clear=all>
| |
| These buttons are only visible when the run is stopped. The user selects the desired PPG Mode by pressing one of the PPG Mode buttons. The buttons will then be replaced by a message as in Figure 6.

|
| After a short time, the PPG Mode will change to the selected mode and the PPG Mode buttons will reappear. The Custom Parameters page can be viewed by pressing the PPG Mode button again.
| | [[Category:BNMR]] [[Category:Webserver]] |
| | |
| The PPG Mode buttons are [[BNMR: Perlscripts#Customscripts|customscript buttons]] which call the perlscript [[BNMR: Perlscripts#change_mode.pl|change_mode.pl]]. The perlscript may take a few seconds to run, so a message is displayed to prevent the impatient user from clicking more buttons.
| |
| | |
| | |
| This line also contains the '''Run Mode''' buttons <span style="font-size:80%">{{Button|name=TEST}}</span> and <span style="font-size:80%">{{Button|name=REAL}}</span>. The coloured (non-grey) button indicates whether the run mode is currently TEST or REAL. The buttons are only visible when the run is stopped. When running, they are replaced by <span style="font-size:80%">{{Button|name=TOGGLE}}</span> for Type 2 runs only. For Type 1 runs, they are replaced by a message.
| |
| | |
| If the run type is REAL as in Figure 5, and the TEST button is pressed, a message will appear (Figure 7), then the run type will change to TEST (Figure 8).
