REMOTE CONTROL DEVICE AND CONTROL SYSTEM

A remote control device includes, in one housing: a communication functional unit that communicates with a programmable controller; an input/output functional unit that outputs control-target-device control information for controlling an operation of a control target device to the control target device on the basis of remote-control-device control information, which is output from the programmable controller and is used for controlling the remote control device, and to which operation result information, which is output from the control target device and indicates an operation result of the control target device that operates on the basis of the remote-control-device control information, is input; a backup managing unit that creates backup data for internal data stored in the remote control device; and a nonvolatile memory that stores the backup data.
