<div class="markdown_content"><p>Communicating between the CoDeSys program and Linux should be possible through /dev/plcvar, according to Kontron.</p> <p>But that's empty </p> <p>Any other idea's? Shared memory is an option, but I cannot figure out how to write to it from my PLC program.</p></div>

<div class="markdown_content"><p>Hi,</p> <p>I like to run a non-CoDeSys real time task together with the CoDeSys runtime. AFAIK, the priorities that can be set in the CoDeSys environment are RTAI priorities. Correct?</p> <p>Next, I like to use the non-CoDeSys task to get input from my CoDeSys task, and be able to give output back.</p> <p>Meaning is to be able to fetch information from a remote database, and feed it into the PLC task.</p> <p>Thanks for any anwsers.</p></div>
