<div class="markdown_content"><p><em>Originally created by:</em> scott_cunningham</p> <p>I am not quite sure which section you are getting the error on ("First Steps..."), but my first guess is you missed the ":" in an assignment statement ("x := 2;", not "x = 2;"). Also, possibly to missed a ";" at the end of a previous line. Goto the line of the code the compiler is complaining about and look at that line and a few previous to it. If you are using CFC, then maybe a wire is not actually terminating at an input/output on a function block.</p></div>

<div class="markdown_content"><p>THis is my first week Programming PLC's and i'm working through the First Steps with CoDeSys.<br/> It all seems to go fine until i try to Build the Project, which brings me up multiply errors with the same code,<br/> Error 4024: PLC_PRG (4): Expecting ":" before "2" as an example.<br/> Now im using the latest software and the instructions are Dated 2004.<br/> I imagine the software has been updated numerous times since the instrutions where last updated.<br/> Could this be where its all going wrong?<br/> Any help would be much appreciated.</p> <p>Gary</p></div>
