<div class="markdown_content"><p>Hi,<br/> just want to say in my opinion this is not correct:</p> <p>Linux.Device=/dev/tty<span style="color: #FF0000;">1</span></p> <p>If you are using for example ttyAMA<span style="color: #FF4000;">0</span> the config file should be<br/> Linux.Device=/dev/ttyAMA<br/> portnum:=COM.SysCom.SYS_COMPORT1;</p> <p>BR<br/> Edwin</p></div>

<div class="markdown_content"><p>Hi Edwin,</p> <blockquote> <p><strong>Zitat:</strong><br/> what is your interfacename in /dev?</p> </blockquote> <p>excuse me, what do you mean?</p> <p>As I told I copied from old CODESYSControl.cfg</p> <p>if it's wrong, the com port would start well? I tryed, for example, to put tty0 but the com port no start.</p> <p><img alt="IMG: dev.jpg" rel="nofollow" src="https://forum.codesys.com//download/file.php?id=2039"/></p></div>

<div class="markdown_content"><p>Yes Edwin,<br/> I'm using really Modbus Serial/RTU.</p> <p>In CODESYSControl.cfg I have:</p> <p><span>[SysCom]</span><br/> Linux.Device=/dev/tty1<br/> portnum:=COM.SysCom.SYS_COMPORT1;</p> <p>(I copy from old CODESYSControl.cfg)</p> <p>I don't understand where is my error, same software, same hardware. I checked serial port with a little python script and it work perfectly, I see LED on when it transmit.</p></div>

<div class="markdown_content"><p>Hi,<br/> so you are using really Modbus Serial/RTU the I agree Johan you need to add the serialcom to <br/> /etc/CODESYSControl.cfg as he proposed in his post before.</p> <p>BR<br/> Edwin</p></div>

<div class="markdown_content"><p>Hi,</p> <p>yes I know, I already add this code in CODESYSControl.cfg. If you no add this raw the com port no start. In my case as you can see, com port start, master modbus start, but communication with slave no work now!!! Before it work perfectly for months!!!</p></div>

<div class="markdown_content"><p>Hi Johan,<br/> yes this overwriting of the CODESYSControl.cfg file is an open point on Raspberry Pi runtime updates <br/> (hope this will be fixed with next version -)</p> <p>BR<br/> Edwin</p></div>

<div class="markdown_content"><p>Hello Suibaf,</p> <p>I had the same problem and fixed it by editing the /etc/CODESYSControl.cfg</p> <p>After the update the section</p> <p><span>[SysCom]</span><br/> Linux.Devicefile=/dev/ttyUSB<br/> portnum := COM.SysCom.SYS_COMPORT1;</p> <p>was missing.</p> <p>Just put this back and it should work again.</p> <p>Regards,</p> <p>Johan</p></div>
