<div class="markdown_content"><p>Hi Turckone,</p> <p>maybe you already found the solution... hopefully!</p> <p>To answer your last question: In the menu project / project settings you will find a tab visualistion profiles. There you can change the profile. But when you have a closed system with your own programming and runtime, this shouldn't be a problem.</p> <p>When using libraries, you sometimes have a situation of rivalling sublibraries, i.e. in one library there is a reference to eg. "standard.lib" version 3.5.5, in your program you use same lib, but version 3.5.8 (only example). Then you might get the same error messages.....</p> <p>Good luck!</p> <p>Alfred</p></div>

<div class="markdown_content"><p>Hi TURCKONE!</p> <p>Did you use an old project with a different version of the plc?</p> <p>I know this error messages and fault behaviour, when I have a different version of runtime on the controller than I have selected in the project. "Update device" often does not work correctly, so I suggest to set up a new project from the beginning and select all the hardware components completely new. (I know, this may be a pain in the a...)<br/> You can copy the code from the old project, and then try build and download....</p> <p>If this doesn't help, it might be a problem of using libraries in the project, that are not compatible with the runtime version or device description file of your controller.</p> <p>Last but not least, the concept of vizualisation profiles is tricky.... maybe you can solve the problem by changing the visu profile in the project settings.</p> <p>Reading my words, I would say - start at the end, because that's the easiest work....</p> <p>Best regards</p> <p>Alfred</p></div>

<div class="markdown_content"><p><em>Originally created by:</em> barkamharikrishna</p> <p>Hello,<br/> if your visualization has some error ( some Version Software will not Pop up Errors in visu) . </p> <p>example u Change something in visu or even you just move visu element . you Need to do clean all and re build then download .</p> <p>i think this will help you.</p> <p>for below two Problems<br/> 1“No connection to the device, please rescan your network.”<br/> 2“Object reference not set to an instance of an object.” </p> <p>solution : save ur Project .. Close completely even codesys and start the codesys again and open Project then clean all , rebuild . and download <br/> if u find Gateway Problem still .<br/> go to Gateway Manager and add new Gateway same as last Gateway and delete old one and scan ....<br/> Regards<br/> Harikrishna</p></div>

<div class="markdown_content"><p>I think it maybe the bugs of Ver3.4.4 ,after I used Ver3.5.0, the program never happen again.</p></div>

<div class="markdown_content"><p>The same problem at my PLC,</p> <p>I'm using Vendor specific RTE, so when I login eg. 10-15 times, the connection breaks and gateway losts (No cennection to the device. Please restart the gateway). I have to restart whole PC (windows XP embedded). I think this is global problem of 3S Gateway.</p> <p>regards,</p> <p>Alex</p></div>
