Posted 21 Mar 2023 (edited) Hi, I need to start interrupt from built-in input 1. Interrupt should be proceed on falling edge. Regarding manual I set: MSKS 7 #0 - enable interrupt in direct mode MSKS 11 #1 - interrupt 141 detect falling edge task no 141 Problem is that interrupt task is not executed - Q2.11 is not ON when signal goes off Maybe you see some wrong settings/code thankls Pawel Edited 21 Mar 2023 by pszczepan Share this post Link to post Share on other sites
Posted 23 Mar 2023 Have you cycled power to PLC after changing the settings? Share this post Link to post Share on other sites
Posted 23 Mar 2023 Maybe not - I stop only PLC program and run again. I'll check soon and see if it was just the reason Share this post Link to post Share on other sites
