Remote management device and remote management method

A remote management server serving as a remote management device is communicably connected to, via a converter, at least one controller serving as a machine tool which allows only direct connection to another device via a predetermined connector, thus exchanging data with a fixed input/output destination and which does not have a setting function of setting a data output destination and a data input destination. The controller is further communicably connected to a mobile terminal via a network. The remote management server includes an input/output control unit configured to control settings relating to data output and data input in the controller and a setting screen providing unit configured to provide the mobile terminal with a setting screen allowing input of setting information relating to the data output and the data input.
