Uploading has always been to send a file and downloading has always meant to retrieve a file from a remote computer. If I send my program from a laptop to a plc, that would be considered uploading on any other platform.
I agree completely, the terminology used by most PLC manufacturers is backwords! But just like the QWERTY keyboard, someone made a bad decision at some point and we are stuck with it.
By the way, anyone ever used the Reliance Electric Automax DCS system? In that system, an Upload writes to the controller, and a download reads from the controller. That makes much more sense to me.
