<div class="markdown_content"><p>I can't run the module 750-653 in PFC200 and Codesys Runtime. <br/> To communicte with Modbus RTU Slave's I am using RS485/Ethernet USR DR302 Modbus RTU/TCP converter. Works great.<br/> As far as I know the 750-653 module is no a device in linux- /dev/ttyS1, /dev/ttyS2 etc etc... , so probably your COM2, COM3 configuration in Codesys will not work. </p> <p>If you find any example using this module in codesys please share it please :)</p></div>

<div class="markdown_content"><p>Hi ;<br/> i have same matter , i cant read or know com number for 750-653 , im using 2 And 3 by default<br/> ,, 1 its for X3 RS232/485 of PFC200</p> <p>Thank you</p></div>

<div class="markdown_content"><p>I runned my application like "Modbus TCP Master" together with MODBUS TCP to MODBUS RTU gateway. Works great.<br/> I have next device with RS485. This device send automatically data frame - 20 bytes periodically. To read this device I can use 750-653 module ? How can read all frame when I have only 4 bytes in receive data in my conffiguration -please find in attachement.</p></div>

<div class="markdown_content"><p>In addition to what they said... contact Wago.</p> <p>There is <a class="" href="https://www.youtube.com/watch?v=TCV_BqcwM30&amp;t=20s" rel="nofollow">this video</a> by Kurt Braun for something very much like this. e!Cockpit is setup as a modbus tcp/ip slave in 1 Docker instance while another instance has the master which in the case would be Codesys. </p></div>

<div class="markdown_content"><p>Damian,<br/> I read on the moxa website that they have linux tty drivers :<br/> <a href="https://www.moxa.com/en/products/industrial-edge-connectivity/serial-device-servers/general-device-servers/nport-5400-series#resources" rel="nofollow">https://www.moxa.com/en/products/industrial-edge-connectivity/serial-device-servers/general-device-servers/nport-5400-series#resources</a></p> <p>You could try getting that working. once you have a tty address, you just have to add the appropriate tty address to your /etc/CODESYSControl_User.cfg file:</p> <p><span>[SysCom]</span> <br/> Linux.Devicefile.1=/dev/ttyMOXA <br/> Linux.Devicefile.4=/dev/ttyMAYBEANOTHERNAME </p> <p>The number after the dot is the COM number to use in CODESYS. </p> <p>Of course, easier would be a MODBUS TCP to MODBUS RTU gateway, like <a href="https://www.moxa.com/en/products/industrial-edge-connectivity/protocol-gateways/modbus-tcp-gateways/mgate-mb3180-mb3280-mb3480-series" rel="nofollow">https://www.moxa.com/en/products/industrial-edge-connectivity/protocol-gateways/modbus-tcp-gateways/mgate-mb3180-mb3280-mb3480-series</a><br/> Ian</p></div>

<div class="markdown_content"><p>So I have a problem. I must have several Modbus Master. Please tell me if is available in Codesys store some library to using Modbus Master RTU over TCP. I have a MOXA devices work as port server with RS485 (TCP&lt;-&gt;RS485). Is it some a simple way send Modbus RTU command by TCP from Codesys ?</p></div>

<div class="markdown_content"><p>no not really, because the PFC has no USB connector..</p></div>

<div class="markdown_content"><p>So, is it available some module on that i can doing second modbus master RTU? </p></div>

<div class="markdown_content"><p>as I tried to say:<br/> There is no com interface in Linux available in the Wago OS on the PFC.<br/> So it is not possible to do Modbus with it.<br/> Wago has an own library which is <strong>not</strong> based on a com device /dev/ttyxx ... this Wago library does handle the process data from KBUS, but this is not compatible with.<br/> So no chance to do 'CODESYS' Modbus via these modules.</p></div>

<div class="markdown_content"><p>Look on the 'print screen' in attachment. One of the article in internet (but polish language) is described that it is possible. <br/> What do you think?</p></div>
