<div class="markdown_content"><p>Your connection configuration should look something like this consuming assembly O-&gt;T will be the hex of the assembly you want to reference for output data - I want 102 (DO Data Only) shown in the Wago web page 102 = 16#66. Producting assembly (T-&gt;O) is the assembly you require for input data - again shown in the Wago web page - I want 108 (DI Data Only) or 16#6C</p> <p>Then set the number of bytes as per the data in the Wago web page too (both 2 in my case)</p></div>

<div class="markdown_content"><p>Make sure the number of bytes matches the values in the Ethernet/IP&gt;Assembly Information section of the Wagos web management page (expand by clicking on the +). The EDS file will probably have defaulted to assemblies 101 and 104. </p></div>

<div class="markdown_content"><p>Hello, </p> <p>I'm getting a similar error Error IoDrvEthernetIP: Connection Failure. (16#1) when connecting to a Ethernet IP Driver (Oriental Motors AZD-AEP driver). But when expanding the error, I'm getting reasons like "Connection timeout" or "Ownership conflict"</p> <p>Is this related to size as well?</p></div>

<div class="markdown_content"><p>In the PLC, the sizes are on the connection tab of the remote adapter.</p> <p><a href="https://content.helpme-codesys.com/en/CODESYS%20EtherNetIP/_enic_edt_target_connections.html" rel="nofollow">https://content.helpme-codesys.com/en/CODESYS%20EtherNetIP/_enic_edt_target_connections.html</a></p> <p>I am not sure about how you get the sizes from the Wago. It is either on the web interface, or you will have to find the manual for it.</p></div>

<div class="markdown_content"><p>Sorry for the question, but could you tell me what are those sizes and what they mean.</p></div>

<div class="markdown_content"><p>The size will have to match. Maybe the 750-352 can be accessed from a webbrowser, that it may tell you the correct sizes to use.</p></div>
