CA Watcher
What is CA Watcher?
CA Watcher is a program which supervises EPICS variables.
The user can receive warnings if desired.
These warnings can be sounds on the local computer, SMS or emails.
The text messaging option is only available at the HZB campus in Adlershof.
All detected alarm states including values are visible in a table
and can be stored for further useage.
CA Watcher should work on every platform, only Java (1.6 and above) is required.
It is available in English and German.

What does the table show?
The table of the main window contains:
- name
- For the PV name.
- If the PV-name is not valid, it is coloured red.
- note
- For individual comments.
- Does not affect the program sequence.
- current value
- If the PV is valid the current value is shown.
- If the PV has enumeration values, the text values will be shown.
- timestamp
- Date and time of the last change.
- status
- Displays the .STAT field of the PV.
- Provides an additional information about severity.
- severity
- Displays the .SEVR field of the PV.
- Displays a global error classification.
- operator
- An alarm is triggered if the comparison with the "comparison value" field is true.
- There is an intelligent selection of valid operators depending on the PV type.
- comparison value
- Value to compare with.
- If the PV has enumeration values, you can choose them from a combobox.

Where can I see the alarms?
The alarm history is stored in a separate alarm window.
The first tab stores the alarms for all PVs.
The other tabs with names store only the alarms for one PV.
Each table can be saved to a CSV-File.
