Hi Paulo, what type of PLC are you using? I am new here. I found this page searching information about DMX protocol to implement it directly to our PLC TECOMAT FOXTROT as an inherent interface/protocol with the function blocks. Is it interesting for you to be in touch during development of PLC/DMX interface? It can take some time. Are you in the stress of some urgent project? Or is DMX for PLC your long term interest?
