I've been looking around for an industrial PC model to take the place of several desktop-class pc's we have running as PI interface nodes. I've been looking for something that I can push as close as possible to the source systems (mainly PLC's and DCS's), so something that I could rail mount right next to the PLCs is appealing. We are a Dell shop, so one option are their new Edge Gateways. Is anybody out there using these? Are they overkill (or underkill) for an interface node? Are you using the I/O for anything?
