<div class="markdown_content"><p>Yes, Data Source Manager seems to be another way to do what you want.<br/> I spoke about network variables, because I use more than Daa Source Manager </p></div>

<div class="markdown_content"><p>Thank you.</p> <p>Network variables did work, and I could use them in two separate projects as well.</p> <p>But I found in the docs in the section after network variables about Data Source Manager <a class="" href="https://help.codesys.com/webapp/_cds_f_datasourcesmanager;product=codesys;version=3.5.12.0" rel="nofollow">https://help.codesys.com/webapp/_cds_f_datasourcesmanager;product=codesys;version=3.5.12.0</a> which seem to solve my problem.</p></div>

<div class="markdown_content"><p>Hello,</p> <p>J think the most simple way to communicate between 2 PLC (Raspberry PI or other !) is to use Network Variables.<br/> You create A application for RAspberryA and B Application for RaspberryB in the same project.<br/> In RaspberryA you add Network Variable List (Sender) and in RaspberryB you create Network Variable List (Receiver). <br/> Please see the online Help to know how to set these Lists.</p> <p>BR </p></div>

<div class="markdown_content"><p>I have 2 Raspberry PI running Codesys programs. And I want program A running on rpi A to read and write data to program B on rpi B.</p> <p>I've been been Googling and trying but I can not find a suitable solution for this.</p> <p>Does anyone have a neat solution?</p></div>
