<div class="markdown_content"><p>As the input data of serial communication is random,<br/> does CodeSys have a trigger bit to read buffer for Read FB of free serial communication (RS485/RS422/RS232)?<br/> It looks like that,when the input buffer of COMx get a data package,it send a trigger signal to ask Read FB to read accordingly,in that case, we can trigger the Read.xExcute timely.</p></div>
