| The default [https://midas.triumf.ca/MidasWiki/index.php/Status_Page MIDAS Status page] has been replaced by a custom status page for the {{bnmqr|join=and}} experiments. Note that the MIDAS client [https://midas.triumf.ca/MidasWiki/index.php/Mhttpd mhttpd] must be running for the webserver to be available. To connect to the Custom Status page, see [[BNMR: Getting Started|Getting Started]]. | | The standard [https://midas.triumf.ca/MidasWiki/index.php/Status_Page MIDAS Status page] is not very useful for {{bnmqr|join=and}}, so it has been replaced by a custom version for these experiments. |

|
| == Custom Status Page ==
| | Note that the MIDAS client [https://midas.triumf.ca/MidasWiki/index.php/Mhttpd mhttpd] must be running for the webserver to be available. To connect to the Custom Status page, see [[BNMR: Getting Started|Getting Started]]. |

| <gallery>
| | The custom status page allows the user to |

| | * view the current state of the run, including scan status, histogram counts, EPICS values and CAMP values |

|
| The custom status page is a [https://midas.triumf.ca/MidasWiki/index.php/Custom_Page MIDAS Custom Page] written for the {{bnmqr|join=and}} experiments.
| | == Implementation == |
| It is written in HTML and Javascript and uses the MIDAS [https://midas.triumf.ca/MidasWiki/index.php/Custom_Page_Features#Access_the_ODB_using_mjson-rpc_asynchronous_functions asynchronous functions] to access the ODB.
| |
|
| |
|
| The custom status page allows users to enter experimental parameters easily, including changing [[BNMR: Experimental Modes|Experimental Modes]] and [[BNMR: Run numbering|run type]]. A [[BNMR: Custom Parameter page|Custom Parameter page]] accessed from the custom status page allows users to enter run parameters easily.
| | 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. |
|
| |
|
| == Features of the Custom Status Page ==
| | The page uses [https://daq00.triumf.ca/MidasWiki/index.php/Mjsonrpc Midas JRPC] calls to talk to: |
| 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. | | * 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 |
|
| |
|
| === Command and Page Buttons ===
| | 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. |

| |
| 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.

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.
