Posted 7 Nov 2023 Hello, I want to ask "is there any formula that shows how to calculate the HMI data logging retention time?" For example, I want to set Trend and Alarm data retention time to 1 month. So how to calculate and setup in GX work3 HMI Designer? If you have any related documents, please share. Thank you. Have a good day! Share this post Link to post Share on other sites
