Alarmlog wrong entry in Field {Comment}

Hello,

I'm using Citect Version 8.10.

I have a problem with recording alarms.

I have defined two devices ("Alarmfile" and "Alarmlog") with the following format:
{TAG,50}{NAME,8}{SUMDESC,76}{ONTIME,10}{OnMilli,3}{OnDate,10}{Comment,20}

Recording alarms to DBF files works fine, but if the Comment field is left empty the status of the alarm (ON) is recorded in the DBF file instead of remaining empty.

Does anyone have a suggestion how I can solve this problem.

Thanks a lot
