Usage : ALARMS processes alarms (events and exceptions).
ALARMS and FrontEnd communicate via ACNET, task name is "AEOLUS"
ALARMS and alarms daemon communicate via multicast, task name is "ALARMR"
alarms daemon communicates with clients via TCP/IP
Restart: ALARMS restarts when CENTRA restarts.
To restart manually, type "acnet restart alarms".
See here for a more detailed document on the alarm system.
See here for a block diagram of the alarm system.

ALARMS is also the name of an Open Access Client front-end. This abstract is
actually defined by name for this OAC.
______________________________________________________________________________
Usage : ALARMS supports alarm devices with a client controlled interface as
well as alarm properties for devices belonging to front-ends that
do not support alarms. Finally, it supports alarms to be sampled
on a specific Tevatron clock event similar to MOOC front-ends.
Use D80 to add an analog or digital alarms block of 20 bytes long
with the node of the alarm block property being ALARMS. The reading
or status property will be scanned at 1 Hertz unless the event #1
field contains a -1, then the reading or status will be sampled on
the Tevatron clock event in field event #2. When a device is going
bad or good the tries needed accumulate at 1 Hertz. This OAC must
download by scanning all the properties in the database to find the
ones it must monitor. Consequently, the scan job to monitor readings
and status will not begin until about 5 minutes after the last
database addition, and this OAC takes 10 minutes or more to
initialize since it runs on a slow Netra and the autotune servlet
shares the CPU.
ALARMS also has a client interface for posting and clearing software
alarms. See gov.fnal.controls.daq.oac.clients.alarms Java code and
Charlie King for details.
ALARMS is a Java Open Access Client (OAC) process which runs on DCE32.
You can view log files for ALARMS in the directory
'daesrv\\engines\files\oac'.
Restart: ALARMS is restarted its DAE is restarted.
