<div class="markdown_content"><p>Hello everybody,<br/> I'm working on a RunTime Plc (Codesys 3.5.16/18.20) connected to an EtherCat bus<br/> with many devices.<br/> The bus has some communication fault but I don't know how understand which is the <br/> device or the cable that has the trouble.<br/> To understand the cause of the problem I would like to read the WKC (Working counter) of<br/> the devices (0x0300...0x030C), how is explained in EtherCat documents, but it seems that the read of <br/> the counter is disabled.<br/> Attached there is an extract of the Ethercat document.<br/> Can anyone give me some advice about how and with function can I read it.</p> <p>Thank you in advance!</p></div>
