<div class="markdown_content"><p>Hi all,<br/> I am a newcomer in the Codesys and EtherCAT world and I am absolutely amazed by the power and versatility of these systems.<br/> I have a Beckhoff EL6022 module (2 RS485 ports) and I would like to know if there is a way to communicate via Modbus RTU with PLCs or if it will be possible in the future.<br/> In my little development system I also have an EL6751 (CAN Master) and it works very well.<br/> I tried to insert the EL6022 in a test project but I did not understand how to use configurations such as Expert Process Data, Process Data, and so on.<br/> However, there are many other things that I didn't understand so I don't get angry<br/> BR<br/> Marcello</p></div>

<div class="markdown_content"><p>Thanks! Will try out a RS232/485 converter. Also got confirmed availability of Berghof EC-COM-02 unit with onboard RS485 (with some deliver time delay). Will update when tested.</p></div>

<div class="markdown_content"><p>An RS232 to RS485 converter will get you out of trouble. <br/> Here's an example from MOXA.<br/> <a class="" href="https://www.iiotzone.com/tcc-100100i-series?c=3" rel="nofollow">https://www.iiotzone.com/tcc-100100i-series?c=3</a></p> <p>If you don't want to use 232 for whatever reason, you can go via ethernet as well. You just install the Linux driver, and the remote comport shows up as a tty. Also from MOXA.<br/> <a class="" href="https://www.iiotzone.com/nport-5100-series" rel="nofollow">https://www.iiotzone.com/nport-5100-series</a></p> <p>I can't see any EL602x in the store or online help.</p></div>

<div class="markdown_content"><p>Sorry for bumping an old thread!</p> <p>Is this still the case (no serial com-port driver available for Beckhoff EL602x-modules)??</p> <p>Im using Berghof EC1000 with Beckhoff-IO and will need RS485 to communicate. Berghof EC1000 has on-board RS232 but not RS485. Speaking with supplier about availability of EC-COM 01/02 module which should provide RS485, but unsure if they are available. Are there other alternatives?</p></div>

<div class="markdown_content"><p>Hi,<br/> no there are no drivers available to have them as serial device.<br/> The only way to use them is to use the process data in your application which is<br/> probably a huge effort.</p> <p>BR<br/> Edwin</p></div>

<div class="markdown_content"><p>I also like to know the answer. I am using EL6021 (RS485).<br/> Can I use it with Codesys Modbus master? <br/> When I try, the Modbus master asks me for COM port... </p> <p>How can we do that?</p></div>

<div class="markdown_content"><p>Hi there,<br/> Is it possible to use some EtherCat serial Communication terminals like the Beckhoff EL6001, EL6002, EL6021, EL6022 right in CODESYS?<br/> I know how to use them in TwinCat with the function blocks provided from Beckhoff but I'm wondering how to use them in CODESYS V3.<br/> Can I use the Beckhoff function blocks in CODESYS? Or are there any other function blocks I can use?<br/> Does someone have a sample code?</p> <p>Thank you.</p></div>
