keyword=Alarm for when iocse20 gets stuck.
I have developed a very simple alarm script which tests for the iocse20 getting
stuck. It is installed on the cvxwrks account on jeffylab, as:
~/pking/g0_BPM_tester.pl
I have started the script in a small terminal window on the top of the jeffylab
console, and have made the window sticky so that it shows up on all workspaces.
It does not take any arguements, and does not produce any output when the
IOC is working. It will produce an audible alarm using the jeffylab sound card
when the IOC gain values do not change when there is beam present; it will
also print the BPM gain values and the beam current as measured by BCM1.
There is not currently any means of acknowlegding the alarm while leaving the
script running; you will need to kill it and restart it after MCC has rebooted the
IOC.
To verify that the script has correctly detected the IOC locking up, you should
request a short beam shut-off and verify that the BPMs report a non-zero position
with the beam off.
I will later try to improve the script and incorporate it into one of the standard
alarm handlers to make it easier to acknowledge the alarms.
