text: <s>[INST] The event task trigger issue I use a registration input (REG1) to a Kinetix 6000 drive (now is K6k_Axis) to trigger an event task in RSlogix 5000. In the event task I need execute MAPC instruction (the run condition is a XIC of K6k_AXis.RegEvent1Status). But I find I have to check Execute task if no event occurs within 5.00 ms in the event task configuration screen, otherwise the MAPC not executed, There is Registration input but it seems that event task not triggered. [/INST] I’m not so expert on this, but I will try to give some help… :smileytongue: Did you test if your MAR instruction is executed ? Anyway, I would like to suggest a test… Using the Event Task as you want ( I mean without the flag over the “execute task if…” ), program inside the routine of the Event Task just a rung with an unconditioned OTL of a bit; this just to see if the Event occurs and your task executes. If this happens, it could be your “RegEvent1Status” bit is sometimes lost… - fuzzy logic \\n </s>
