<div class="markdown_content"><p>I had similar assertion failed error messages today.<br/> I am fairly new to Codesys.<br/> I tried using SFC for the first time, I usually use ST.<br/> Anyway I had errors in some of my transitions.<br/> I copied and pasted transition code and forgot to change the target of the code.<br/> I started getting lots of the assertion errors but now I have sorted out the problems and it compiles OK the assertion error messages seem to have stopped.</p> <p>There do not seem to be any other responses to your post, did you resolve your problem?</p></div>

<div class="markdown_content"><p>Any idea what this is? I get it every time I try to compile a program. The only way around it is to click "Ignore" about 50 times. After that the program compiles and runs fine.</p></div>
