<div class="markdown_content"><p>Dear all.</p> <p>I am trying to connect RaspberryPi(installed CODESYS 3) to PLC using EtherNet / IP.<br/> In this system, PLC is a scanner and RaspberryPI is an adapter.</p> <p>I was able to connect PLC and RaspberryPi by Forward_Open command.<br/> However, I could not get RaspberryPi's data using ExplicitMessage, and I got an error response.<br/> (General Status code : 0x14 =&gt; "Attribute not supported")<br/> When I checked the command output from the PLC, "Logical Format" was "16-bit logical value".</p> <p>I want to connect PLC to RaspberryPi with "16-bit logical value". Do I need to make any configuration changes?</p> <p>When I conducted a communication test using two RaspberryPi (one scanner + one adapter), data was successfully acquired."Logical Format" was "8-bit logical value" when communication was successful.</p> <p>Could you help me this problem ?<br/> Thank you.</p> <p>【Explicit Message data】<br/> - Service Code : 0x0E (Get_Attribute_Single) - Class ID : 16#01 (Identity Object) - Instance ID : 16#01 - Attribute ID : 16#05 (Status) <br/> 【CODESYS Information】<br/> - Raspberry Pi : Target Version 3.5.14.10 - Ethernet device : Version: 3.5.14.0 - EtherNet/IP Adapter : Version: 3.5.14.10 </p> <p><img alt="IMG: WireShark data.png" rel="nofollow" src="https://forum.codesys.com//download/file.php?id=4556"/></p></div>
