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.
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 ===
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

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.

=== 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.

Introduction

The standard MIDAS Status page is not very useful for bnmr and bnqr, so it has been replaced by a custom version for these experiments.

Note that the MIDAS client mhttpd must be running for the webserver to be available. To connect to the Custom Status page, see Getting Started.

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
  • change which experimental mode is being used
  • change whether a run is "real" or "test" data
  • change/view the helicity and beam settings
  • enable/disable the alarm system
  • force neutral beam checks to be re-referenced

Implementation

We force Midas to use our custom status page by deleting the file $MIDASSYS/resources/status.html with a symlink to bnxr_common/custom/status.html from the bnmr repository.

The page uses Midas JRPC calls to talk to:

  • the mode_changer.py program for changing modes and changing between real/test runs
  • the rf_calculator_fe.py program for visualizing the PPG and PSM settings as plots

The page uses standard Midas custom page tools for editing ODB settings. An ODB hotlink is used for the neutral beam re-referencing.
