jkc8560 Posted April 1, 2015 Report Share Posted April 1, 2015 Working today with a V1040, I found something I was not aware of; complex HMI screens use a tremendous amount of scan time. I have placed 100 very small bar graphs on the screen with 100 very small bianary objects to create a graphic display of a process control profile. Whenever this screen is active the scan time will increase from 2 ms to 10 ms and this is not good for my application. I am trying to control a rather fast process with 100 profile points via analog output and 10ms is on the edge of non-functionality. Is there a way to slow the refresh rate on this particulat HMI screen, so as to decrease the scan time? Quote Link to comment Share on other sites More sharing options...
