<div class="markdown_content"><p>Oh I see. <br/> Thought it didnt work with SFC in actions but turned out that's only the case if the fb is programmed in sfc.</p></div>

<div class="markdown_content"><p>Hi.</p> <p>Not. </p> <p>Fb extends from Fa. And Fb will be programed in st.</p> <p>Create in Fb an action to be programed in sfc mode.</p> <p>From the main of fb call super^() and call his sfcAction...</p></div>

<div class="markdown_content"><p>I'm not quite sure I understand what you mean.</p> <p>To clarify I have two fbs; FB_A and FB_B, both programmed with SFC where FB_B extends FB_A,<br/> and I need to have FB_A running cyclically. </p> <p>Do you mean I should create an action in FB_A with SUPER^() as content, and run that action in main program?</p></div>

<div class="markdown_content"><p>Hi. Somlioy.</p> <p>Create in extended fb an action where you will implements the sfc. </p> <p>From the main program you can call the action with the grafcet, super, and any other action you want run parallel to sfc.</p> <p>Be healty!</p></div>

<div class="markdown_content"><p>Yes, but what if the funtionality needs more than one scan cycle ? most of the time you need call another FBs and need several cycles.</p> <p>My point is, seems that, on the contrary of OOP standar languages, in Codesys you have to call explicitly super function to execute the base code.</p></div>

<div class="markdown_content"><p><em>Originally created by:</em> rickj</p> <blockquote> <p><strong>Zitat:</strong><br/> I have to write on his body super^() to get the base functionality of FB_A running.</p> </blockquote> <p>Put the desired functionality into a FB_A method, which is inherited by FB_B. Then simply call the method, from FB_B. No need for ^super.</p></div>

<div class="markdown_content"><p>Hello,</p> <p>I have FB_A and FB_B, and FB_B extends FB_A.</p> <p>I call FB_B countinuosly from one task, but inside FB_B I have to write on his body super^() to get the base functionality of FB_A running.</p> <p>Then When I call the FB_B methods from some point of the program, all the code is able to work.</p> <p>Question is, maybe there is another way to achieve this without access the super pointer.</p> <p>Someone know another way ? </p> <p>Thanks.</p></div>

<div class="markdown_content"><p>Hello</p> <p>I got two function blocks programmed in SFC where one extends the other.</p> <p>How can I call SUPER^(); without placing it in every action-step?</p></div>
