maybe this FAQ should explain why this could happen:&lt;br/&gt;
 l &lt;a class="" href="http://forum.codesys.com/viewtopic.php?f=22&amp;amp;t=5641&amp;amp;x=10085&amp;amp;p=10085&amp;amp;lan=en" rel="nofollow"&gt;viewtopic.php?f=22&amp;amp;t=5641&amp;amp;p=10085#p10085&lt;/a&gt; l &lt;br/&gt;
Looking forward for 3.5SP5 to have a really good solution for this.&lt;br/&gt;
Which plc and which version of it are you using (the placeholders in the devicedescription are responsible for the library versions)?&lt;br/&gt;

&lt;p&gt;Hello all,&lt;/p&gt;
&lt;p&gt;For a project i need several PLCs (codesys 3.5) communicating with each other. We like to do that with TCP/IP.&lt;br/&gt;
We have to transfer structs with information. The structs contain arrays and normal variables.&lt;br/&gt;
The CAA Net Base Services looks the perfect library.&lt;/p&gt;
&lt;p&gt;I downloaded the example program in the Codesys store. Every thing runs fine on a local soft PLC.&lt;/p&gt;
&lt;p&gt;But when i make a project in the controller it self, the library gives a lot of errors.&lt;br/&gt;
When i choose "try to reload library" i'll get a pop up that the library is  not installed om the system.&lt;/p&gt;
&lt;p&gt;Does this mean that this library is not installed for this type of PLC? &lt;br/&gt;
Is the TCP/IP communication always availible on every type / brand of PLC in code sys 3.5?&lt;/p&gt;
&lt;p&gt;regards Patrick&lt;/p&gt;&lt;/div&gt;</summary></entry></feed>
