Current Status of Monitoring and Control Pictures on the Server

The main CDF page:

1. The detector subsystem buttons should navigate the operator to the specific subsystems. These pictures are the responsibility of the detector groups. Once these pictures are developed, Margherita Vitonne or Mike Kirk can provide the link to the pictures on this page. An alarm in the a subsystem should turn the corresponding button on this page red.
2. The server button toggles the directory from which your pictures are retrieved; either the server or your local pc directory. To enable this on your local pc, copy all the directories from the server to the C:\ drive on your local PC.
3. Two examples of the hierarchy currently on the server are the Plug Temperature Monitoring System and the Power Supply Monitoring System.

Example of navigation: Plug Temperature Monitoring

1. The Plug button opens the Plug Menu page.

2. The Plug Temp button opens the Plug Temperature Monitoring page developed by the detector group responsible for the Plug Temperature Monitoring and Control.

3. This page will eventually display global box temperatures. Currently, clicking on a PMT box opens a picture containing box specific temperature, % heating and cooling, set point, and dew point. The update alert window is a VB form which can display warnings which require an operator response. The is just one form of an alarm display. This picture contains a timer which monitors temperature control processes and automatically adjusts the process to keep the boxes in a safe condition.

4. The expert button on the previous pictures is password protected to restrict access to expert pages. for example:

5. The alarm button on the Plug Menu page will open a picture containing a summary of the Plug Temperature Alarms. Which fields are displayed is optional. The fields in this Alarm Summary Object are: the time at which the alarm was received, the last time this alarm occurred, the specific detector subsystem node, which tag in the Fix Database, the status (Low, Medium or High), and the current value of the Tag.
The Alarm Extension field contains a picture name which can be displayed to provide the operator with additional information about the alarm. In this case the specific PMT box with a temperature alarm can be displayed by clicking on the line in the spreadsheet. This is optional but does combine the alarm summary list with the 'drill-down' approach being implemented on the main pages. In other words, this alarm should also turn the plug button on the main page red, and the plug temp button on the Plug Menu page red etc., eventually guiding the operator to this PMT box.

6. The Plug Temperature subsystem currently uses Analog Alarm blocks for alarming. The values of the blocks can be set using the EDA toolkit.

Example of navigation: Power Supply Monitoring

1. Clicking on the 1st Floor button on the Main Page:

opens a picture displaying all the racks on the West side of the first floor.

2. The East Side button open a picture of the East Side Racks.

3. The blue Power Supply button simulates the rack button functionality and opens a picture which displays the voltages of the power supplies in that rack.

4. The view history buttons opens a graph of the current voltage on one channel.
