I have a Christ (no joke) Touch screen HMI. Model Comfort+. I looked on Christ Elektronic's website and they don't offer that model. The only products I see are touch display's and embedded PC type displays. This is connected to a Siemens's PLC. I tried connecting a keyboard and mouse and it doesn't act like a PC type device. I would like to replace it with something made in the USA, but need to get the software for this one and upload it if possible. Anyone have any experience with these and could provide some background? Its a German company and I sent an Inquiry but I'm not real hopeful.
