<div class="markdown_content"><p>Hi all, new to the Codesys environment and was hoping someone could help me out.</p> <p>I have a question about a behavior I am seeing when I am logged into the PLC and monitoring the program.</p> <p>Program:<br/> - Main program is using the CFC language <br/> - It has a few function blocks that are using the SFC language.</p> <p>When I double click to "hop into" the FB to see what the SFC's steps are doing, I always see "???".<br/> Logging out and back into the PLC fixes the behavior and allows me to see the steps running in the SFC.</p> <p>Any reason why I get the ??? when first jumping into the function block?</p></div>
