<div class="markdown_content"><p>I would recommend using the OsCat Network Library it has been tested and validated. It also has a built in NET Var module or Modbus TCP Slave/Master.</p> <p>You have to be signed in to download. This has been updated for CoDeSys V3.</p> <p><a class="" href="http://www.oscat.de/community/index.php/topic,1784.0.html" rel="nofollow">http://www.oscat.de/community/index.php ... 784.0.html</a> m </p></div>

<div class="markdown_content"><p><em>Originally created by:</em> Matthias S.</p> <p>Hello,</p> <p>I would also prefer network variable. This is the easiest way.<br/> As an alternative to the "raw" sockets, I can also recommend the CoDeSys CAA_NetBasedServices.lib in V3.<br/> This lib encapsulat the socket interface. I used the TCP Server and Client Blocks in a project without problems.</p> <p>By the way: what specific problems do you have?</p> <p>Thanks,<br/> Matthias</p></div>

<div class="markdown_content"><p>It is much easier to use Network Variables. For this you don't have to program anything (just configuring).<br/> In the menu Tools-Options-Features, enable Network Variables.</p> <p>Add a Global Variable list to your application and set in the properties that the variables should be sent over the network.<br/> In the application of the other device, add a Network Variable List and link this to the GVL of the other application.</p> <p>Now the application will automatically send the values of the variables from one PC to the other.</p> <p>It is most easy to have both applications for both devices in one project.</p></div>
