<div class="markdown_content"><p>not correct , as a program has no I/O defined.<br/> however it is possible to do:</p> <p>copy the program and give it other name (something like FB_SFC_blabla)<br/> change indeed the name program to Function_block<br/> now define what variables are used as Input<br/> and as Output and which ones are global and local etc.<br/> within the program no changes are needed.<br/> check the real I/O Tags as you will mess it up when using double.</p> <p>It is normal for a beginner to do it this way.<br/> I only use Function blocks and my main program just calls blocks. so my main program is max one page, same for a sub btw make them max one page so you can overview what happens.</p></div>

<div class="markdown_content"><p><em>Originally created by:</em> scott_cunningham</p> <p>Open the object. Change the word PROGRAM to FUNCTION_BLOCK above where your variables are defined. Close the object. It should switch to an FB. I use v3.x now and this is how it is done in 3.x, but if I remember correctly, it was the same on v2.3.</p></div>

<div class="markdown_content"><p>I have a program written as a SFC but I now need to implement several instances of the program so I thought it best to have the code as a function block. Is there a way to convert the program into a function block or would I need to start again?</p> <p>Thanks,</p> <p>Tony</p></div>
