<div class="markdown_content"><p>Hi forum,</p> <p>just a quick question:</p> <p>in terms of efficiency, there are some difference between implementation languages?</p> <p>For example in Siemens S7, if you write a program in structured text, before performing the program the PLC "translates" the structured text (or any other languages) into instruction list text and then execute it. So if you really need "speed" the best way is to program in instruction list text.</p> <p>Codesys will do the same or whatever implementation language I choose the program will have the same cycle time?</p></div>
