<div class="markdown_content"><p>A simulation is not accurate, the trigger does work for one cycle, (taking very small time, not enough to be visible at screen,<br/> you will need to use a SET coil to see it working correct.</p></div>

<div class="markdown_content"><p>rtrig's output is only True for one cycle when the signal changes, so for maybe 20ms if you have a default cycle time set.<br/> The fact that you can see it at all is due to the scan of the visualisation. <br/> If you stick a tof at the end of it with let's say 3s then you will see the trigger.</p> <p>Sent from my SM-G935F using Tapatalk</p></div>

<div class="markdown_content"><p>Hi,</p> <p>I need to use Rising Edge Trigger in a program. To understand how it functions, I wrote a simple program with single input and output. Simulation can be seen here: <a class="" href="https://youtu.be/SLGQLkMbE2g" rel="nofollow">https://youtu.be/SLGQLkMbE2g</a></p> <p>In the video you can see that R_Trig function block detects the rising edge of the input on only two occasions.</p> <p>Is there a problem with software/ function block or anything else?</p> <p>Thank you</p></div>
