<div class="markdown_content"><p>Hello,</p> <p>which plc are you using, is this Control Win?<br/> I would recommend to the check this examples here:<br/> <a class="" href="https://store.codesys.com/serial-com.html" rel="nofollow">https://store.codesys.com/serial-com.html</a><br/> -&gt;install it via CODESYS shopping cart and open it then here<br/> 'c:\Users\&lt;yourwindowsusername&gt;\CODESYS Examples\SerialCom\1.0.0.1\SerialCom.project &lt;/yourwindowsusername&gt;</p> <p>There are two applications in you need to decide which one is better for your needs (SyscomExample is more low Level based on the syslibs)</p> <p>If you see the project, there is nothing in the device tree according the Serial communcation... so for plain using the com port<br/> this is not needed.<br/> If you use a higher level protocoll like modbus rtu, then you need to add a modbus serial com port.</p> <p>BR<br/> Edwin</p> <p><img alt="IMG: serialcom.jpg" rel="nofollow" src="https://forum.codesys.com//download/file.php?id=3398"/></p></div>

<div class="markdown_content"><p>I am currently using CoDeSys V3.5 SP12 trying to grab drab some sensor data using a controller. Let me touch on the hardware architecture first.</p> <p>Computer -&gt; LAN cable -&gt; Conprosys controller -&gt; RS-232 Serial cable -&gt; CHINO temperature senor</p> <hr/> <p>I have seen guides on how to open serial com ports using "COM.Open" and such but they are focusing on Computer -&gt; Serial -&gt; Controller. In my case I am hoping to open the Controller SERIAL COM port. I searched for the data sheet and it indicated that the CoDeSys syntax for that controller serial com port being "PORT 1"</p> <p>Link to mentioned controller (CPS-PCS341MB-DS1-1201): <a class="" href="https://www.contec.com/jp/download/contract/contract3/?itemid=d66e4a64-6719-4675-869a-ab50c6cb2dc2&amp;downloaditemid=377a41d5-c7f9-43cc-b5f0-9d370d53120a" rel="nofollow">https://www.contec.com/jp/download/cont ... 370d53120a</a></p> <p>So how do I actually go about activating that Serial com port on the controller in CoDeSys?</p> <hr/> <p>Another issue being more of CoDeSys.</p> <p>When I add Devices in CoDeSys, which do I select for my LAN then Serial configuration?</p> <p>MODBUS_COM&gt; MODBUS_SERIAL_DEVICE</p> <p>or</p> <p>MODBUS_COM&gt; MODBUS_MASTER_COM_PORT&gt; MODBUS_SLAVE_COM_PORT</p> <p>or</p> <p>Ethernet&gt; MODBUSTCP_SLAVE_DEVICE</p> <hr/> <p>This has been confusing me for quite some time now, have no background on CoDeSys. Appreciate any help and confirmation, thanks.</p></div>
