My brother recently bought a KEP HMI for a small project, he asked me to check out the software which is called EasyBuilder 8000 http://www.kep.com/downloads/index.html, I made a simple screen at work and connected to compactlogix, I was up and running in about a hour or so, I am not an HMI guru, but exporting/importing tags was a pretty straighforward process. I also tested at home with rslogix 500, using df1 and virtual ports. Anyways I thought I could share it with you folks since is free. Enjoy
