<div class="markdown_content"><p>Had the same thing and this solved my problem, Thanks!</p> <p>Please allow me to clarify the procedure for people that might have the same problem...</p> <ol> <li>In codesys you double click on the device </li> <li>go to PLC Shell. You will only see a gray field with an input area at the bottom</li> <li>type serialmode rs485 and enter</li> </ol> <p>Et voila... </p></div>

<div class="markdown_content"><p>I runed my project (Modbus).<br/> I set in PLC Shell:<br/> serialmode rs485</p> <p>Very strange thing, because earlier I runed command serial mode and I get : rs485, so I didn't even think about overwriting it - but it helped.</p></div>

<div class="markdown_content"><p>Are you sure ?<br/> Linux.Devicefile.4=/dev/ttyMdm0 this is for SMS Modem - Modem I use on port COM4 in CODESYS - it works.<br/> Linux.Devicefile.1=/dev/serial this is for Modbus? - I use Modbus on port COM1 in CODESYS.....</p> <p>Earlier I had have this settings and it was good.</p></div>

<div class="markdown_content"><p>Exactly, I had to install firmware in PLC again (WAGO_FW0750-8xxx_V030107_IX13_r40667), because earlier I did test with firewall and I block access to PLC.</p> <p>My steps:<br/> I lost acces to WAGO PFC200, so:<br/> I installed fresh firmware on WAGO, next I Updated PFC - from my Codesys Environment, next i installed target license and I did "download to" my project. Next I have just changed the setting in<br/> /etc/CODESYSControl.cfg</p> <p><span>[SysCom]</span></p> <p>Linux.Devicefile.1=/dev/serial<br/> Linux.Devicefile.4=/dev/ttyMdm0</p> <p>And everything works good (even SMS's) except modbus communication.<br/> What can be wrong ?</p></div>
