A communication terminal includes: a network communication section configured to communicate with a device that possesses a target to be accessed and access information; a setting section configured to set, for a transmission means that is used to carry out transmission by communication carried out by a program for exchanging messages, (i) specifying information for specifying the target and (ii) an action that the device is caused to execute with respect to the access information, the specifying information and the action being set by an operation of a user so as to be associated with each other; and an execution control section configured to send the transmission means to the device, and cause the device to execute, with respect to the access information on the target that is specified by the specifying information having been set for the transmission means, the action having been set for the transmission means.

The present invention enables a user to accurately perform operation when the user operates a touch panel of a terminal to control propulsion of a vehicle. A terminal control unit 20 causes a touch panel 9 to display a vehicle control screen on which an operation button allowing touch operation is displayed, moves a position of the operation button following a movement of the position of the touch operation, and maintains a state where the touch operation is performed on the operation button when the position of the touch operation moves after the touch operation is performed on the operation button displayed on the vehicle control screen, transmits a propulsion instruction signal instructing propulsion of the vehicle to an information processing device 4 provided in a vehicle while the touch operation is being performed on the operation button displayed on the vehicle control screen, and stops transmission of the propulsion instruction signal in response to ending of the touch operation on the operation button.

A smart valve positioner is provided with a local user interface with non-mechanical touch buttons and a display inside a positioner housing under a housing cover for locally operating the valve positioner. The touch buttons are user-operable by touching the touch buttons when the housing cover is open. The housing cover is arranged to make the touch buttons user-operable from outside the housing by touching the housing cover, when the housing cover is closed.
