The study aims to develop a remote monitor & control system of a ship based on the network. The monitor & control system, which is integrated by PC, Programmable Logic Controller (PLC), and the ship equipment, serves as Distributed Data Base Management and Real-time Multitasking. By applying the Home Page technology of ASP and Active X, the Servo-Home-Page acts as the man-machine-interface to supervise the ship equipment. The results show that the computers and PDA in use, i.e., the clients of the remote system, are able to successfully supervise the equipment of a ship. The characteristic of the wireless PDA facilitates the remote monitor & control to work efficiently.
