Communicaton with Rockwell by DF1 protocol

I am implementing an Industry 4.0 project and, to collect field data, I adopted IoT2050Basic (6ES7647-0BA00-0YA2). Everything is going well and without difficulties, but on some machines I will need to use a communication flow exchanging data with Rockwell CPUs using the DF1 protocol (mandatory). In the Node-red repertoires we did not find any flow with this type of communication active (the only one I found "node-red-contrib-df1" is owned by a company that does not sell it, and, although it is available for installation via npm, it is incomplete). Can anyone recommend another repertoire or flow that I can test and use in my project?
