Scan time is too long

Recommended Posts

Hi,

In my Unilogic programme, Scan time is between 6-9ms, with Ladder Time Max about 2.7ms. But sometimes, aperiodically, Scan time is 35-38ms, while Ladder time is the same. Never 15 or 20 or 25ms, always 35-38ms. I need Scan time to be less then 10ms. How to solve this?

Hi,

Only by viewing the application it will be possible to understand why the scan will jump to 35-38ms.

There are several actions that might cause the scan time to increase such as loops (Jump to region) , handling data tables such as insert row or remove row that will need to copy large amount of memory etc..
