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.

A control system and a functional unit are capable of freely setting a place at which an operation for executing an access process is performed independently of an installation place of a controller. A CPU unit capable of communicating with a storage unit, and a plurality of functional units communicatively connected to the CPU unit are included. The functional unit includes an input unit including a switch that receives a user operation. The input unit generates a command for executing an access process when an input portion receives execution of the access process for accessing the storage unit from an IO unit. A designated IO unit executes the access process.
