yes that is a bit much.<br/>
better use visualisation or ODP.</p></div>monitoring mulitple PLC's via TCP/IP2020-02-27T22:56:00.026000Z2020-02-27T22:56:00.026000ZKiranKhttps://forge.codesys.com/u/kirank/https://forge.codesys.com9cf3505f1428eaa719ffdf65dc9e4f479b3bc89b<div class="markdown_content"><blockquote>

<p>Hi,<br/>
I just wanted to know what are the limitations of TCP or UDP protocol:<br/>
Distance<br/>
No of bytes for each frame<br/>
No of nodes <br/>
and other limitations if any .</p>
<p>Regards,</p></div>monitoring mulitple PLC's via TCP/IP2020-02-27T22:55:58.257000Z2020-02-27T22:55:58.257000Ztimvhhttps://forge.codesys.com/u/timvh/https://forge.codesys.com0b6bc20ec259671046fff74ff2574064d2a930d9<div class="markdown_content"><p>Make sure all devices have different IP adresses.</p></div>monitoring mulitple PLC's via TCP/IP2020-02-27T22:55:56.628000Z2020-02-27T22:55:56.628000Zbobtr1https://forge.codesys.com/u/bobtr1/https://forge.codesys.com9b774d80cd6f65b74d1d43e367b96a45a9c5fd24<div class="markdown_content"><p>Doug,</p>
<p>I am monitoring 3 PLC's using CoDeSys on this computer as I write this with no trouble. I sometimes monitor 5.</p>
<p>There's no problem with CoDeSys or TCP/IP. It may be that you're using a hub. I found that using a switch insteadof a hub works better.</p></div>monitoring mulitple PLC's via TCP/IP2020-02-27T22:55:52.106000Z2020-02-27T22:55:52.106000Zdtrhttps://forge.codesys.com/u/dtr/https://forge.codesys.comef3f0951819dbd876dcc2c03e59ad048b70c349a<div class="markdown_content"><p>Greetings everyone,</p>
<p>I am logging in an monitoring multiple projects (3 at the moment) running on three different PLC's using a network hub. Once I start running I lose communication after a period of time (< 15 - 20 s) to one of the PLC's. All 3 applications are running fine, just no communications (LOGIN) to one of them. Any ideas or is this not possible due to limitations of TCP/IP or CoDeSys?</p>
