Hi, I am a PLC programming expert. I can help you on this project. I've done a lot of projects like this before. For this, I'll just be needing some files and info from you to do this. Like the back-up program, model of the old and new vfd and model of its communication modules. Or we can talk about the details over chat. You can visit my profile to check some of my finish projects on Siemens PLC. Thank you
