<div class="markdown_content"><p>I can access my OPC tags via opcda:///CoDeSys.OPC.02/{key} with Softing OPC client application. But Labview uses the <a class="">opc://localhost/CoDeSys.OPC.02/PLC1:tag</a> path and doesn't have a connection with the OPC server at the moment. I really don't know where to look.</p></div>

<div class="markdown_content"><p>Okay I think my OPC server is running. Now I want to communicate from LabView, but I'm wondering what the OPC url is.<br/> <a class="">opc://localhost/</a>"CoDeSys"/PLC1 it's probably something like this, but I want to change "CodeSys" in it, I have no idea where I can change this (I don't want to change every OPC-link in LabView).</p> <p>Thank you for every help already!</p></div>

<div class="markdown_content"><p>Nevermind, it's working right now. I needed to change to another TCP/IP configuration.</p></div>

<div class="markdown_content"><p>Ok, great to hear that it's possible with PLCWinNT.<br/> Problem right now is that I can't load the program. When I select PLCWinNT as target and want to login it gives me an communication error.<br/> I changed the communication parameters to 'localhost' and gateway connection to local, like I found in this guide: <a class="" href="https://www.yumpu.com/en/document/view/7404167/robotino-view-kommunikation-mit-opc-festo-didactic/11" rel="nofollow">https://www.yumpu.com/en/document/view/ ... idactic/11</a> m </p></div>

<div class="markdown_content"><p>if you run winnt then just start your program without using simulation. in demo it will run for 2 hours.</p></div>

<div class="markdown_content"><p>I added variables for the PLC I/O so I don't work with the PLC driver anymore.</p> <p>Now I want to get the OPC server start working, it's not clear for me if it will work in Simulation mode (Codesys) or maybe with PLCWinNT soft PLC.</p> <p>Vision</p></div>

<div class="markdown_content"><p>no sorry, the codesys software can run on a PC to have remote I/O, however you can simulate I/O even when remote, but not a driver as communication is very hard to simulate, you can however use a visualisation to simulate communication by sending commands via the vis to the program, and later on replace it with proper drivers.</p></div>

<div class="markdown_content"><p>But it must be possible to simulate the program without changing the PLC config I suppose? Is that not the whole matter of a software PLC to simulate the I/O?</p></div>

<div class="markdown_content"><p>programs and libs can be target specific, for example a PC can not have direct I/O so when you specify them it will give compile errors, the choice of target is therefore important before starting a project.</p></div>

<div class="markdown_content"><p>Problem at the moment with PLCWinNT is when I select the target my PLC config is lost, thereby my program gives error so I can't go online anymore.</p></div>
