<p>We will add this to the Raspberry PI Application section too. ( Just as information how to do it)<br/>

<p>Note: to moderator: Maybe, seeing this, the reply I wrote would be better put here.</p></div>Multiple USB devices different COMPORTs2020-02-27T17:05:02.635000Z2020-02-27T17:05:02.635000Zeschwellingerhttps://forge.codesys.com/u/eschwellinger/https://forge.codesys.comc44f8a575fb68f2eabbe747137d468bf9791104a<div class="markdown_content"><p>Hi,</p>
<p>hm if you have added ttyUSB in the config file you could access<br/>
the serial com's in CODESYS<br/>
Com1,Com2,Com3... that is the way it works.<br/>
Maybe I do no really understand it, please explain .</p>

<p>Unfortunately I havent found anything regarding my question using the search function.</p>
<p>Here is my question:</p>
<p>I want to connect 4 serial devices to the 4 USB ports on Raspi. All 4 devices are exactely the same (Roboclaw motor controller).<br/>
Using udev rules I am able to give all of them reproducable names, even if I disconnect and reconnect them, so thats all fine.</p>
<p>To use the serial USB in codesys I know that I need to add the following lines to CODESYSControl_User.cfg:</p>
<p><span>[SysCom]</span><br/>
Linux.Devicefile=/dev/ttyUSB<br/>
portnum:=COM.SysCom.SYS_COMPORT1</p>
<p>After this I am able to control the devices vial the CAA serial library.</p>
<p>My question is now if there is a way to assign each Motorcontroller to a specific comport, so that I can decide which motorcontroller to "speak" without sending every command to each motor?</p>
<p>Thank for any help!</p></div>
