<div class="markdown_content"><p>I have a program and the only change I made was add 3 global variables, each a string and as soon as I try to run the program in simulation mode I receive this error. These three variable are included in the write file from the master (PLC) to the slave (Screen), as soon as I remove them I can run the program no problem. </p> <p>When I go to Online&gt; Show Call stack... there is nothing in there.</p> <p>I can get it to run a single cycle, as soon as I try to get it to run another cycle I receive the error.</p></div>
