AVEVA HISTORIAN 2023 : Unable to log data cyclically

Hello,

I’m Iftekhar, and I would like to ask about data logging behavior in AVEVA Historian 2023.
I’ve configured data logging through IOServer with a 1-second cyclic frequency, but I’ve observed that the Historian is logging data in Delta mode — that is, only when the tag value changes.

Could you please advise how to configure the system so that data is logged cyclically every 1 second, regardless of value change?

Thank you for your assistance.

Please see attached images.

Best Regards,

Iftekhar
