<div class="markdown_content"><p>Indeed, VAR_STAT can be seen as if a variable is declared in the body of the main POU (so an FB or a PROGRAM). In techspeak: the declaration of the VAR_STAT is placed on the stack of the parent POU, instead of on the stack of the METHOD itself.</p> <p>To sum it up: 'regular' variables in the METHOD declaration lose their contents after ending the METHOD, while VAR_STAT variables never lose their content after ending the METHOD. </p> <p>I Hope this anwsers your question.</p></div>

<div class="markdown_content"><p>Situation:<br/> - I have a program with many methods.<br/> - Some methods use fb/vars that need memory between one call and next call</p> <p>If a won't declare it in program body, how i can proceed? I found VAR_STAT and test it, with success.</p> <p>Help says that static variables retain their value when the application exits the function block</p> <p>It is true also for PROGRAMS?</p> <p>Thank's in advance</p> <p>Massimo</p></div>
