Hi:

The alarm handler simply reports the alarms provided by records.

Hello all
 
In the CSS Alarm Handler client we get alarms with these status messages:
1.       CALC_ALARM.
The calc record will set a CALC alarm when for example the formula in the CALC field is garbage.

2.       SCAN_ALARM.
EPICS IOC database processing logic sets this alarm if it cannot process a record.

3.       TIMEOUT_ALARM.
Device support code may set this alarm when it cannot communicate with a device

Can somebody explains what is the meaning of these messages and how to fix ?
Fix the underlying reason:
Enter a correct formula in the CALC field,
debug your IOC database,
check that the device is powered and the network cable is plugged in.
