<div class="markdown_content"><p>I assume that you do not have a source code of your or client Siemes system. I think there is not an easy way to do that, because you simply do not know where is what on what adresses, offsets and so on... If your Siemens panel is broken buy a new one, or buy VIPA little bit cheaper and in most cases compatible.</p> <p>regards,<br/> Alex</p></div>

<div class="markdown_content"><p>Hello.<br/> I want to use a CoDeSys panel to communicate with a Siemens S7-300 PLC via the Ethernet port without installing the MODBUS addition to the Siemens.<br/> Basically, I want to replace a Siemens panel without doing any changes in the Siemens PLC.Is it possible, and how?</p></div>
