<div class="markdown_content"><p>Hi <br/> The Output of R_Trig is active only for 1 cycle so you would Need to do something like this</p> <p>FUNCTION_BLOCK FB_Test<br/> VAR_INPUT<br/> xInTrigger : BOOL;<br/> END_VAR<br/> VAR<br/> fbRTrig : R_Trig;<br/> END_VAR</p> <p>fbRTrig(clk := xInTrigger);<br/> IF fbRTrig.Q THEN<br/> // the code that Needs to work only on Trigger<br/> END_IF</p></div>
