Subject: Limit (between 0.1 and 86400) of Archiver Appliance sampling period for PVs

Dear all,

We have some diagnostics PVs which update every 0.04 secs (25Hz) and we want to archive all the values. However, the AA management web UI prohibits setting the sampling period to the value lower than 0.1 secs with the following prompt:
"The sampling period should be a non-zero number between 0.1 and 86400"

Why does AA enforce this restriction? Can it archive PVs with the sampling period less than 0.1 secs?


Thanks,
Lin
