Hi
I am working on an application using Labview DSC 2017. I would like members' feedback on a couple of issues.
1. I have around 500 double SVs in my library, with alarming enabled for all and logging of data for almost 175. The alarms are generated and logged without a problem. However, for a couple of variables there is a problem in alarm activation. The variable has Lo(L) and Lo_Lo(LL) alarms defined. When values decreases the Lo alarm is activated correctly. However, as it decreases further Lo_Lo should be activated but it is not. On the alarming page, I have set the acknowledge type to AUTO, both alarms have same priority. I disabled the Lo alarm the Lo_Lo was successfully activated. I am unable to figure this out, any suggestions would be welcome.
2. While retrieving the alarms using Alarm and Event Query VI I place the filter on Timestamp and Newest entries first. The results are returned but it seems Labview is ignoring the start time. The query fetches results 5 to 10 minutes prior to the start timestamp. I have checked the query filter values seem fine.
Thanks

Has anybody else encountered this issue?
I was wondering if it is a issue in DSC 2017
