When the webserver is used to connect to a MIDAS experiment, the standard [https://midas.triumf.ca/MidasWiki/index.php/Status_Page MIDAS Status page] is shown, unless
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MIDAS Status page] is not very useful for {{bnmqr|join=and}}, so it has been replaced by a custom version for these experiments.
it has been replaced by a '''Custom Status page'''. This is the case for the  {{bnmqr|join=and}} experiments. A  [[BNMR: Custom pages|custom page]] written specifically for the  {{bnmqr|join=and}} experiments replaces the standard MIDAS Status page. It is called the '''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]].

== Features of the Custom Status Page ==
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:
;Figure 3 Command and Page Buttons and Page Update Information
* the <code>mode_changer.py</code> program for changing modes and changing between real/test runs
[[Image:Bnmr_top_buttons.png]]
* the <code>rf_calculator_fe.py</code> program for visualizing the PPG and PSM settings as plots
<br clear=all>
In the middle of the top line on the Custom Status page (Figure 1) 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 (Figure 3). 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. More buttons appear when a run is in progress (Figure 4).
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.

The actions of these buttons are described in Table 1.

=== Page Update Information ===
The page update information is also visible in Figure 3. 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 3). This minimum time is 5s.  The relevant ODB data are read asynchronously using the [https://midas.triumf.ca/MidasWiki/index.php/Mjsonrpc#Javascript_client_library  MIDAS mjson rpc client library] each time a full or partial reload is done. The times of the last full and partial reloads and ODB data last read are also shown in Figure 3.
 
==== Countdown and Progress ====
A '''countdown''' to the next full reload is also visible. If the page is set to update every 10 sec, the Countdown will count down from 6 to 1, when a full page reload will occur.
 
The '''Progress''' display is a numerical progress flag. This is a debugging tool to indicate the progress of reading the data from the ODB. It works on a timer, updating every half a second. The Progress Code numbers/colours are explained in Table 2. The functions whose names begin with "''mjsonrpc''" refer to [https://midas.triumf.ca/MidasWiki/index.php/Mjsonrpc#Javascript_client_library MIDAS mjson rpc] functions. All other functions are found in the Javascript source code  {{Filepath|path=/home/bn[mq]r/online/custom/cs_functions.js}}. If the progress code is shown in black, the callback has been received or the function is finished. If the page is between updated, the same black code number would fill the progress line. Instead, the colour is alternated between black and grey.

=== 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  [[BNMR: Experimental Modes|Experimental (PPG) Mode]]. This changes when the mode is changed by pressing one of the
[#Select PPG and Run Mode|PPG Mode buttons]. The run number (Table 3) is shown in different colours for a '''test''' or '''real''' run (see [[BNMR: Run numbering]]). The [#Select PPG and Run Mode|Run Mode buttons] are used to switch between test and real runs.

|}
|}
The run state is shown in different colours depending on the run state (Table 4).
An orange box (Table 5) is present on the Status Line when the run is in transition. This normally occurs when the run is being started or stopped. If the run is stuck in transition, an alarm message may appear.
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 6). Most are provided with a checkbox so the user can change the values from the custom status page.

This line on the Custom Status Page contains the PPG Mode change and Run Mode buttons  (Figure 5).
;Figure 5 PPG and Run Mode switch buttons

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.
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 the message "Toggle not supported".
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).

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.
