Re: Means of comparing alarm status with a conditional in a CALC record

["Johnson, Andrew N. via Tech-talk" <tech-talk at aps.anl.gov>]

There are some additional values for the STAT field that can’t be transmitted over CA as an ENUM (the protocol only sends the first 16 state names as shown in Tim’s graphic from MEDM), but the calc record will get their numeric values. The full list of STAT values can be found in any of include/alarm.h, include/menuAlarmStat.h or dbd/menuAlarmStat.dbd in Base.

Hi Andrew,

Yes, just specify the record's stat field in one of the calc record's input fields.  You'll get a number from the following list

All,

 

I was wondering if there was some method to compare the alarm severity, where I want to determine if one of my record’s STAT field is set to be NO_ALARM or COMM. Can that be done using something like a CALC record?

 

Thanks,

Andy
