Marin59 Posted November 24, 2020 Report Share Posted November 24, 2020 Hi, can anyone suggest what is the execution time for float math functions on a Vision Controllers 700/1000/1200? Also where this type of data is available? Thanks Quote Link to comment Share on other sites More sharing options...
MVP 2021 Flex727 Posted November 24, 2020 MVP 2021 Report Share Posted November 24, 2020 I've never seen this data, but it should be fairly easy to determine empirically. Load a blank program into a PLC, check the scan time, add 10 or maybe even 100 rungs with the float math function you're interested in, then check the scan time again.

MVP 2021 kratmel Posted November 24, 2020 MVP 2021 Report Share Posted November 24, 2020 You can masure this time via Utils/Debug/Interval (Start-Stop). Quote Link to comment Share on other sites More sharing options...
MVP 2021 Flex727 Posted November 25, 2020 MVP 2021 Report Share Posted November 25, 2020 That's good to know, @kratmel! I didn't realize Vision could monitor in units of micro-seconds (or even tens of micro-seconds). Quote Link to comment Share on other sites More sharing options...
John_R Posted November 25, 2020 Report Share Posted November 25, 2020 I never realized that was there.... Does the Start Interval have to hang on the rail before the ladder you want to monitor, or can it be at the end of a conditional rung so it only starts when the rung goes true?

AlexUT Posted November 25, 2020 Report Share Posted November 25, 2020 You have to use pair - Start Interval/Stop Interval. Stop Interval store measured interval into linked DW. B.R. Quote Link to comment Share on other sites More sharing options...
